Co-founders wanted | EU adult platform

Co-founders wanted | EU adult platform

Hey all,

Two of us have been building and we're now looking for 1-2 co-founders to take it further with us. We are already building for six months besides our full-time jobs.

Upfront and honest, because it saves everyone time: it's an adult platform. Legal, above-board, built to comply with EU law - not a grey-area thing. If that's a dealbreaker for you, no hard feelings, better to know now.

The idea

A verified-only social platform for adults to connect with like-minded people. Community boards, chat, profiles, a feed. Creators can also sell content on a per-post basis (no subscriptions - a deliberate choice). Users can buy platform subscriptions for premium features. EU/UK focus, with Germany as a key market. We care about it being a genuinely trustworthy, non-sleazy place, which is most of the reason the harder parts below matter so much.

The team right now

  • My colleague - senior fullstack dev, located in southern German
  • Me - business side + senior frontend, located in Austria

Neither of us has founded a company before. We were probably a bit naive going in, but we believe in the vision and there's real work behind it already.

We were three, actually. One person stepped away - not over anything between us, but because he decided the space itself is just too tough. Complying with everything a social platform has to, and an adult one in particular, is a steep hill. It's a fair concern and we're not pretending otherwise. We're going in with our eyes open, which is exactly why the risk/legal role below matters as much as it does.

Where we are

  • Solid working prototype: feed, discussion boards, chat, profiles, notifications, real-time via websockets
  • Pre-incorporation - no company founded yet
  • No payment provider integrated yet

The hard parts - why we want help

  • Payments: finding and integrating a provider that will actually work with adult content
  • Legal & compliance: EU obligations around CSAM/NCII, age verification, content moderation, etc.
  • Production-readiness: getting from strong prototype to something we can safely launch

Who we're looking for (one or more of these):

  1. Senior software architect - helps shape and build the platform with us. Not a CTO title; decisions made collectively.
  2. Finance / CFO - ideally someone who has founded and scaled a company before.
  3. Risk / audit / legal - someone willing to own the compliance side of a genuinely tricky domain.

It's an ambitious project in a difficult field with real regulatory weight - but a large market if we get it right.

The practical stuff

  • Equity: equal, co-founder-level split. It vests over time with the usual cliff, so it's earned rather than handed over on day one.
  • Commitment: it's a side project for now, so part-time to start. The plan is for it to become full-time work for all of us as it grows.
  • Location: EU-based and remote. This is a hard requirement.
  • Timeline: targeting launch in spring/summer 2027.
  • Funding: bootstrapped for now. We plan to raise once the platform is hardened on the legal side and payments are in place.

If this sounds like your thing, drop a comment or DM me. Happy to walk through the prototype and where we're headed.

As show offs are only allowed on Fridays I'm not disclosing the name or website url of our already publicly reachable marketing website.

Do you ever wish you could test startup decisions before actually shipping them?

I’m working on a product for founders who want to make better decisions before spending time, money, or traffic on the wrong thing.

The problem I’m trying to solve:

A lot of startup decisions are expensive to validate.

Changing pricing can hurt conversion.
Changing copy can confuse users.
Changing onboarding can reduce activation.
Launching a feature can waste weeks.
Running interviews or A/B tests takes time and often requires traffic you may not have yet.

So I’m building Polyhyle: a simulation platform where you can model a product/business scenario and see how different synthetic user segments might react.

Examples:

  • simulate a pricing change
  • test positioning and landing page copy
  • predict objections before launching
  • compare feature concepts
  • simulate user reactions to a competitor move
  • estimate impact on conversion, churn, adoption, or trust

To be clear: I don’t think simulated users replace real customers.

But I do think they can help founders narrow down bad ideas faster, generate better hypotheses, and decide what is actually worth testing.

I’d love feedback from other founders:

What’s one startup decision you wish you could simulate before making it?

My app got more attention than I thought

Early this year, I built a privacy-focused document scanner and management tool for myself. It is free with no ads.  It’s offline-first, with optional features to back up your scans to Google Drive, iCloud, Paperless-ng, and Nextcloud.

The idea was born out of my dealing with paper documents, business cards, and having a digital copy of my driver's license without needing to purchase a scanner.  I didn't build it with the intention of starting something up, but to solve my own problem. It’s great to see other people using it, which I only discovered last week by looking at App Store data. I decided to check my email and waitlist, and there have been requests about when the Android version will land.

Just want to share this small success

Building for EU ESG market from India

I'm an Indian founder building a data intelligence tool focused on European ESG compliance (specifically CSRD/ESRS workflows).

​The core problem we solve is the manual grunt work: sustainability teams burning hours digging through 800+ page reports just to find specific disclosures or metrics, where every number needs to be 100% traceable back to the source page/table.

​Product-wise, the engine works, and we have clear pricing/credits locked down. But cross-border GTM is where I'm hitting a wall. Selling B2B from India into Europe comes with obvious trust, compliance, and timezone hurdles.

​For anyone selling B2B into the EU (especially in ESG/compliance):

​Where did you find your first early conversations—cold outbound on LinkedIn, specialized communities, or channel partners/consultancies?

​How did you handle the trust barrier of being an offshore founder in a highly regulated EU space?

​Would love candid advice or teardowns.

Europe-based business co-founder

Hi everyone,

We’re a small technical founding team based in APAC looking to connect with a business-focused co-founder or small team based in Europe to jointly validate, build and grow technology companies.

Our team currently consists of:

  • I’m a software engineer specialising in platform engineering, cloud infrastructure and scalable systems.
  • My co-founder is an AI engineer with experience building AI-driven products and intelligent systems.

We can take ownership of much of the technical side: product engineering, architecture, cloud infrastructure, AI integration, automation and scaling.

What we’re looking for now is the business side of the founding team, potentially someone who could eventually become the CEO / commercial co-founder and lead market validation, partnerships, sales, operations, fundraising and go-to-market within Europe.

We currently have two main concepts we’re interested in exploring.

1. Grocery / food-tech platform

We’re exploring a grocery and food-commerce platform that could combine several business models:

Instacart-style marketplace: connecting customers with grocery retailers and enabling fast online ordering and delivery.

HelloFresh-style model: curated products or meal solutions, subscriptions and recurring customer relationships.

More vertically integrated supply-chain model: as the company grows, potentially developing stronger relationships with producers and suppliers and gaining greater control over sourcing, fulfilment and distribution rather than remaining only a marketplace.

The interesting opportunity for us is combining AI, logistics optimisation, supplier technology, subscriptions and marketplace infrastructure to see whether we can create something differentiated for European markets.

2. Real-estate / PropTech platform

We have also been developing the concept for an all-in-one real-estate and rental platform.

Think of something combining the simplicity and discovery experience of Airbnb with a more complete operating platform for landlords, property managers and tenants.

For renters, the platform could provide:

  • Property discovery and intelligent property matching
  • Viewing requests and communication with landlords or agents
  • Rental applications
  • Digital lease agreements
  • Rent and deposit payments
  • Payment reminders and history
  • Maintenance requests and tracking

For landlords and property managers, it could provide:

  • Property and listing management
  • Tenant management and screening
  • Lease management
  • Automated rent collection and reminders
  • Maintenance management
  • Occupancy and rental-income analytics
  • AI-assisted rental pricing
  • Portfolio dashboards and property insights

The business could eventually operate through a combination of subscriptions, listing fees, transaction fees and premium services, while building a larger marketplace connecting tenants, landlords, property managers and potentially other real-estate service providers.

We see significant potential to apply AI and automation to areas such as property matching, pricing, tenant workflows, documentation, support and portfolio analytics.

What we're looking for

Rather than simply finding someone to execute our ideas, we want a real founding partner who challenges assumptions, understands the European market and helps decide what is actually worth building.

A background in any of the following would be particularly interesting:

Business development, startups, marketing, finance, operations, retail, logistics, supply chains, real estate, PropTech, marketplaces, SaaS, fundraising or partnerships.

You don't need to already be a CEO. We care more about entrepreneurial ability, commercial thinking, execution and founder fit.

Partnership

This is not a job opening.

We’re looking at this as an equity and profit-based partnership, with ownership and responsibilities structured around each founder's contribution and long-term involvement.

We’re also not limiting ourselves to these two concepts.

If we connect with the right person or team and discover a stronger SaaS, AI, marketplace or technology opportunity, we're completely open to exploring and building that together.

The goal is simple:

Strong technical founders + strong European business leadership + local market knowledge**.**

Validate the problem, speak to customers, build quickly, launch, measure traction and keep pushing the ideas that prove they have a market.

If you're based in Europe and interested in building something from the ground up, DM me with a little about your background, location and the type of company you'd like to build.

We can connect on LinkedIn first, exchange ideas and see whether there is a genuine founder fit.

Also happy to hear from existing business teams looking for technical co-founders, not only individuals.

I’m building 'Pezzo' a dating app where you match other people instead of yourself

Honestly, I think traditional dating apps have some pretty big problems, especially lately.

It often feels like men struggle to get matches, while women can end up with an overwhelming number of choices. In both cases, I think the endless swiping can become repetitive and frustrating.

But while endlessly swiping, I noticed something interesting...

You scroll through Tinder, Hinge, etc. and sometimes you see someone and immediately think:

“Wait… I saw a profile 5 minutes ago that would be perfect for this person.”

But there's nothing you can do about it.

So I decided to create Pezzo (Piece in Italian)

The idea is simple:

Instead of swiping for yourself, you're shown two dating profiles and asked:

“Would these two make a good match?”

Yes or No

You can also say why you think they're compatible.

Over time, I want to build statistics around these “ships”:

“You and X have been matched by 27 people.”

And if the same two people keep getting matched, they could eventually choose whether they actually want to connect.

Basically, I'm trying to turn matchmaking into a social game.

I think there's something really interesting about letting other people notice compatibility that you might completely miss yourself.

Right now I have basically 2 test users, so I'm looking for the first 100 people to try it and tell me honestly:

Is this actually fun? Is it useful? What would you change?

Startup registration

Hello,
I am a eu citizen (French) residing outside of Europe for now (Saudi Arabia).
I am currently building a platform online and it can possibly provide subscription based services.

I have multiple ideas, this is only one of them , but all of them provides this kind of product. The target users is worldwide.

I want to have a real company and have this legal. Where do I start? Where should I open my company?

- In Saudi Arabia I can’t open the company as a resident non saudi.
- I want to be legal and doing the right thing if I ever go back to France or Europe.
- for now no external investment, aiming to grow organically, should my decision be based on if I want to take profit out or no?

- I have no legal background and more of a tech background so I dont know from where to start

Thanks,

LF technical co-founder

We're looking for a technical co-founder to join the team, replacing our current CTO.

He's been poached by a startup offering him a ridiculous salary — he wants to buy a house, so I get it. He's staying around for calls when needed, but we need someone to properly take the reins on the tech.

The product is roughly 80% built — you'd be taking over an already largely-made system, not starting from scratch. The gap between where we are and launch is three things:

  1. Finishing the single-creator theme (white-label) — this is already underway; the foundational work (CSS pipeline, design tokens, cleanup) is done, and the theme build itself is in progress. Needs finishing off.
  2. Automated DNS for creator subdomains — the core domain infrastructure is built and live (creation, SSL, admin management). What's left is the last mile — automated preview domains for new creators — which hasn't been started yet.
  3. Balance & payout system — this is the part with the most left to do. A couple of underlying pieces exist (payout intake, notifications), but the backend foundation, creator-facing UI, and admin/ops tooling for payouts are all still to be built.

A good chunk of this is already in progress — you'd be finishing things off rather than starting cold.

We're building a creator commerce platform for the adult industry, made up of three products that all sit on one underlying system:

  1. Multi-creator white-labels — functional and live, but early, and working through the cold-start problem
  2. AI creator-generation tool — releasing next week
  3. Headless CMS — the multi-creator white-label above is built on top of this

We've architected it so that individual creator sites will eventually feed content into the multi-creator network — so as creators post, the network itself gets more valuable. It's a long-term network effect play.

Me and my other co-founder have been in the adult space for 4 years. We've got relationships with site owners and brands who'll be promoting our products directly to their models. We've also got a waitlist of ~10,000 models who've registered interest in our single-creator site product, and our partners will be pushing it out to their creator networks too.

Barriers to entry in adult are high — payments, regulatory compliance, age assurance, etc — and we've built an out-of-the-box compliant solution. It's not a clone, not a script. Everything runs on our own infrastructure going forward.

Looking for someone with real technical chops — proper system architecture experience, comfortable using AI orchestration for coding rather than vibe coding. There are a few repos to maintain (platform, white-label, API) so you need to genuinely understand how it all fits together, not just bolt things on.

It's an equity-only role for now, salary tied to earnings — we want to get the wheels turning properly before we try to raise (there's a stigma around adult that makes fundraising harder).

We also have some v. strong propsects in podcasting and music who want to use the same system, but see adult as the quickest and most sustainable cash.

If you're interested, send me a DM with a bit about yourself — previous work, relevant experience, and any questions you've got. If it looks like a good fit, we'll set up a call and go from there.

I built Self, a tool that turns your CV into a personal website in under a minute

Hi everyone, I’m the founder of Self, a tool that turns your CV into a personal & professional website.

I started working on it because building a personal site often feels like more effort than it should. Most people already have their experience, education, projects and skills written down in a CV, but they still have to choose a website builder, copy everything over, arrange the sections and make the site look good on mobile.

With Self, you can upload your CV as a PDF, image, or text file, or even import it from LinkedIn. Self uses this information to create a responsive website that you can edit and publish. You can change the text, layout, and design, and add visual project sections if you work in a creative field where your work is best showcased through images.

I recently changed the product from a seven-day trial to a permanent free plan. The original trial felt too restrictive because people could not properly use or share their website before deciding whether they wanted to pay. The free plan now includes one published website on a self.cv subdomain, with no time limit.

There is also a Pro plan for people who want to use a custom domain, access more design options, view analytics, control SEO settings and use AI-assisted editing. My goal is to keep the basic version genuinely useful while charging for the features that are more valuable to professionals who want greater control.

Self is intentionally more focused than a general website builder. It is for people who want a professional website without having to design and build one from scratch.

I would really appreciate any feedback on the idea, the onboarding experience, the generated websites or the free and paid plans. You can try it as a guest, without creating an account 😎

Cheers!

I have a question for you.

I currently have a trademark right related to cars in the area of EU.

The trademark is also protected by the Madrid system, which gives it potential protection in other countries.

I want to produce electric supercar as an industrial designer

and the headquarters of the company to be established wants to be in Europe.

So I'd like to get an investment for my first project, what should I do? (Except for defective countries)

Request for threat-model feedback on an open-source crypto inheritance design

I’m building Vaultpass web application, an open-source crypto inheritance system, and I’m looking for technical criticism of the design rather than promotion.

Current design:
- The vault is encrypted client-side with AES-256-GCM before upload.
- The encryption key is split using a 2-of-3 Shamir Secret Sharing scheme.
- One shard stays with the owner.
- The other two encrypted shards are currently held by the service and are used in the succession path after a time-based dead man’s switch.

The important limitation: because the service currently holds two of three shards, it can reconstruct the key in the succession path. I am not calling this zero-knowledge. Removing that trust-model concession is the next architecture milestone.

The crypto core is MIT-licensed and open source:
https://github.com/lionzion351-dev/crypto-core

I’d value criticism on four points:

  1. Are there implementation or misuse risks in using Shamir Secret Sharing this way?
  2. What threat-model assumptions should be documented more explicitly?
  3. What failure cases should be tested before asking for an independent review?
  4. Would you recommend a different succession design, such as timelocked transactions, multisig, or a threshold-signature approach?

This has not had a formal external audit yet. Please assume the code is unaudited and do not use it with real assets. I’m looking for people willing to challenge the design and, if interested, review the implementation publicly.

How EU startups manage tech complexity

A startup can start with a fairly simple application and eventually end up with APIs, databases, Redis, background workers, containers and cloud infrastructure.

For a small team, keeping all those pieces connected and understandable can become a bigger challenge than expected.

How are European startups dealing with this?

Do you keep the architecture simple for as long as possible, invest in DevOps early, or use AI-assisted development to reduce some of the engineering overhead?

106 design engineers on EU pay data

There's no reliable public number for what a design engineer earns in Europe. The salary aggregators mostly report mechanical and hardware engineers who share the job title, and the role means something different at every company. So I ran an anonymous survey: 106 design engineers across Europe, total comp including realistic equity value, captured in bands.

Disclosure: I run a small firm that places design and product engineers, so I had a commercial reason to want this data. Posting the findings here rather than a link.

Overall median: €115k. Middle 50% between €70k and €140k. A quarter earn under €70k, a third earn over €130k.

By company stage:

  • Pre-seed / seed: €90k (n=24)
  • Series A: €115k (n=17)
  • Series B: €115k (n=11)
  • Series C+ / growth: €140k (n=11)
  • Large / public company: €115k (n=15)
  • Not a startup: €70k (n=24)

Non-startup companies pay the least, below even pre-seed. I don't have an explanation from the data. It might be that traditional companies benchmark this role against internal design or IT bands rather than engineering ones.

By country (only samples large enough to mean anything):

  • UK: €140k (n=19)
  • Spain: €115k (n=9)
  • Sweden: €115k (n=9)
  • Germany: €90k (n=14)
  • France: €70k (n=10)
  • Italy: €60k (n=8)

Spain and Sweden landing at the same median despite very different living costs was the one that stood out. Remote work may be flattening the geographic hierarchy at the top end.

By contract title:

  • Design Engineer: €115k (n=48)
  • Product Designer: €90k (n=15)
  • Frontend Engineer: €70k (n=12)

Seniority would explain this, except it doesn't hold up — comparing people with the same years of experience, the gap stays. Only 46% of respondents have "Design Engineer" on their actual contract.

I can't say from a survey this size why the title tracks so closely with pay. It could be that companies using the design engineer title already understand the role. It could be that the title sets which salary band gets used for benchmarking. Probably both.

Other cuts: pay jumps once at around four years (€90k to €115k) then flattens. Remote and fully onsite both €115k; hybrid came in at €90k, which I can't explain.

Caveats: self-selected sample from my network and networks of people who shared it, not a census. Bands mean medians use midpoints, accurate to within a band rather than to the euro. Country samples outside these six were too small to report.

Happy to get into methodology in the comments.

Seeking a co-founder:ConstructionProduct

TL;DR: I’m building BuildEye, a field-first construction management platform designed around how construction sites actually operate.

I come from the construction side. I’m looking for a technical/product co-founder who wants to turn what started as an internal solution into a real product for construction companies.

The problem
A huge amount of site management still happens through:
phone calls
WhatsApp/Viber messages
Excel sheets
handwritten notes
photos
verbal instructions
An engineer walks the site, notices that something is unfinished, calls a subcontractor, writes something down, requests materials from procurement, checks manpower and tries to remember what changed yesterday.
The information exists — but it is fragmented.
And most construction software I’ve seen adds more administration instead of reducing it.

What I’m building
BuildEye is designed as a simple operational layer between the construction site and the office.
The goal is not to create another generic task manager.
The goal is to let a site engineer quickly understand:
what is finished
what is late
where each subcontractor is working
how many workers are on site
what problems are open
what materials have been requested
what needs attention today
how the project is progressing by building, floor, apartment and trade
The product is currently being developed as an AppSheet-based MVP so that workflows can be tested quickly against real construction operations.

What I bring
I bring the construction side.
I’ve worked directly on construction sites and I understand the workflows, the people, the problems and the gap between what software designers think happens on site and what actually happens.
I’m defining the product and testing the workflows from that perspective.

Who I’m looking for
Not an employee and not an AppSheet freelancer.
I’m looking for someone who wants to potentially build BuildEye as a company with me.
Ideally someone with experience in:
AppSheet / Google ecosystem
workflow automation
databases and integrations
product development
eventually moving from low-code MVP to a scalable SaaS architecture if the market requires it
You don’t need to be a construction expert.
That’s the part I bring.
But you should be interested in understanding construction operations deeply enough to build software that people on site will actually use.

Why I think there’s something here
Construction has plenty of software.
What it still lacks is software that a site engineer can actually use while walking the site, without turning every action into administration.
That’s the problem I want BuildEye to solve.
If this sounds interesting, DM me.

I’d be happy to show you what I’ve built so far, the workflow behind it and where I think this could go

Looking for PaaS/cloud recommendations f

Me and another founder are building a B2B SaaS aimed at European and UK customers.

Of the two founders, I’m the techy one. The other founder is the product owner, has experience in the industry and handles sales, so I’m currently the only person doing the technical work, including development and infrastructure.

Because the software needs to have 99.99% availability, the technical requirements leave us with relatively few options in terms of providers.

Since I’m the only person doing the tech, my thinking was to use a PaaS for the first customers rather than spending a lot of time managing infrastructure ourselves.

At the moment, I have Scalingo, Clever Cloud and Northflank on my list. There don’t seem to be many reviews or much discussion about them, so I was wondering if anyone here has used them. If you have, what was your experience?

I’ve also looked at providers like Hetzner, OVHcloud and Scaleway, where managing more of the infrastructure ourselves is an option. I was shocked by the amount of the negative reviews in Trustpilot.

So:

  • Has anyone here used Scalingo, Clever Cloud or Northflank?
  • How reliable have they been for production workloads?
  • Are there any other PaaS or cloud providers you would recommend?
  • Has anyone here run a B2B SaaS with high availability requirements in Europe?

Cheapest EOR for hiring globally?

We're 5 hires in through an EOR across Germany and the Netherlands, and what we're paying per hire is at the point where the question of setting up a direct entity in at least one of those markets has come up internally.

But I have no idea whether that crossover happens somewhere between 5 and 15 hires or depends entirely on the country.

Part of what makes it hard to compare is that we're not clear on what we're paying as EOR management fee versus what's employer contribution markup, and with our current provider those line items aren't clearly separated, so comparing against the cost of running direct payroll in Germany is basically guessing.

A founder I know had been on Deel before switching and mentioned Workmotion as having a cleaner cost breakdown, which is what made me wonder if the problem is the provider or just EOR pricing generally.

So, what's the cheapest EOR you've found for Europe-first hiring, and at what team size did EOR stop making sense for you?
