Edit: thanks everyone for the interest and messages. No more inquiries needed as I have a lot of messages to go through and chats to have. Thanks again.

I’m a professional engineer, based in western Canada. 6 years of experience in heavy civil construction as the prime contractor and experience in engineering consulting. I’ve identified a pain point in heavy civil construction safety and subcontractors management. I know how to fix it, I know the industry well and have mapped my idea out, fully explained it, determined an offer to sell to clients (B2B), and have validated the idea with other people in my industry, and I have the industry connections to sell it. It would be as a B2B SaaS, reoccurring revenue.

I’m seeking a technical cofounder, preferably located in Vancouver Canada or close by, and someone with mid to senior level full stack experience.

I’ve been reaching out to connections on LinkedIn but I also want to post here. Please share your portfolio/linkedin and experience and if I can dm you to chat more.

Hey All,

I am a non-tech founder myself .

I went though learning curve of building with AI.

So I created this small WhatsApp group - we already have a few founders , and want to share if someone wants to join.

It is exclusive for non-tech founders so people who had a tech background please do not apply/approach.

Looking forward to connect and learn with like-minded founders

Comment or DM if interested.

Cheers

Hey everyone,

I'm Esteban, founder of Sidetick, a French startup trying to rethink how we recognize and reward cultural fans.

We're building a Cultural Passport: instead of knowing fans only by what they buy, we want to recognize their actual engagement with artists, venues and events.

I'm not a developer. I previously had a technical co-founder, but we recently went separate ways, so I'm currently rebuilding the product with a lot of help from AI.

And honestly, AI is great but I prefer to share a beer with people.

I'm looking for someone who wants to build and think with me, not someone waiting for a list of tickets to execute.

The project is early, the company already exists in France, and there's a lot to build and challenge.

Current WIP:
https://sidetick-ticketing-api.vercel.app

I'm open to remote / international profiles.

Equity available, depending on fit and involvement.

​

I’m K, the founder of Cryptheim.

The idea started from a simple observation: people with a high security profile still rely on a completely fragmented stack.

One app for encrypted messaging. Another solution for identity. Another for crypto or sensitive credentials. Separate threat-intelligence feeds. Google Maps for navigation. A security company when something becomes physical.

None of these systems really understand the complete situation.

I want to build Cryptheim to change that.

What Cryptheim is

Cryptheim is an AI-powered personal security platform built around a hardened smartphone.

The long-term product combines:

a cryptographically secured smartphone

hardened Android/AOSP-based operating environment

hardware-backed encryption and secure elements

mechanical privacy / kill switches where technically feasible

end-to-end encrypted messaging, calls, video and files

cryptographically verified identity

secure storage for credentials and digital assets

policy-based transaction/signing controls

real-time cyber and geopolitical threat intelligence

OSINT and commercial/private intelligence sources

AI-powered personal risk analysis

risk-aware navigation

travel security

emergency assistance and human escalation

an enterprise command platform for security teams

The phone is important, but Cryptheim is not just a phone company.

The device becomes the trusted endpoint through which we can connect:

device → identity → communications → assets → location → intelligence → risk → response

Imagine travelling to an important meeting.

Instead of simply telling you that protests are occurring somewhere in the city, Cryptheim could understand that the incident is close to your planned route, that your destination is inside an elevated-risk area and that your device has simultaneously connected to a suspicious network.

It could then recommend another route, increase the device security posture, protect sensitive operations and — if necessary — connect you or your organisation with human security support.

That is the product I want to build.

Who I’m looking for

I’m looking for a technical co-founder / CTO, not an agency, freelancer or someone who only wants to advise from the sidelines.

Someone who wants to help turn the concept into the actual company.

Ideally you are strong in several of these areas:

Android / AOSP / mobile systems

mobile or endpoint security

applied cryptography

secure communications

backend / distributed systems

AI/ML engineering

threat-intelligence pipelines

privacy-preserving architecture

device attestation / secure elements / hardware security

infrastructure and cloud security

You do not need to know everything on that list.

What matters more is that you can think like a systems architect, know where you need specialists, and are comfortable making difficult security-versus-product trade-offs.

What I do not want to do

I don’t want us to make claims like “unhackable phone” or pretend we can reinvent an entire mobile operating system, manufacture proprietary hardware, build an intelligence company and create a global protection network on day one.

The first version should be much more disciplined.

My current thinking is:

Phase 1: hardened AOSP/reference hardware + secure communications + identity + intelligence MVP

Phase 2: integrated Cryptheim reference device + Command platform + enterprise pilots

Phase 3: certification, production hardware and broader security services

The architecture should assume that components can fail or be compromised and use compartmentalisation, zero-trust principles, hardware-backed trust and minimal data collection to limit the blast radius.

Current stage

Cryptheim is currently at the concept / company formation stage.

I am working on the product vision, market positioning, business model, funding strategy and early company architecture.

The founding technical team will be formed as part of this stage.

I’m not going to pretend that we already have customers, revenue or a finished device when we don’t.

The next objective is to turn the vision into:

a credible technical architecture

an integrated MVP

a reference-device prototype

design-partner conversations

initial enterprise pilots

a security and certification roadmap

I’m planning a founding/pre-seed round to finance that transition rather than trying to raise a huge hardware round before we have proven anything.

Why I'm looking for a co-founder instead of hiring a CTO

Because the technical architecture is the company.

Security cannot be outsourced as an implementation detail.

The person making decisions about the operating environment, cryptographic boundaries, identity model, intelligence architecture, telemetry, AI, privacy and hardware trust should have founder-level ownership.

I’m looking for someone who wants to sit on the same side of the table and build this for years.

Not someone waiting for a Jira ticket.

The bigger vision

If we execute this correctly, Cryptheim could eventually sit between a high-risk person or organisation and the threats around them.

Not only:

“Your communication is encrypted.”

But:

“We understand the changing risk around you, protect the systems and assets you depend on, and help you decide what to do next.”

That combination of secure endpoint + encrypted communications + intelligence + AI + navigation + response is the company thesis.

If you are a senior technical builder who finds mobile security, cryptography, intelligence systems and ambitious hardware/software products genuinely interesting, I’d like to talk.

Full-time / all-in co-founder role.

DM me with a little about yourself, what you’ve built, which part of this problem interests you most, and — importantly — what you think is wrong with the idea.

I’d much rather meet someone who challenges the architecture than someone who simply tells me it sounds great.

Hi there! Solo founder here. I’ve spent the past six months researching, designing, validating and building an AI product for the health and service space. We’re currently pre-seed. I’m leading the product, design and marketing with a UK-based partner focused on the commercial side.

It is complex, with enterprise potential and long-term defensibility. The product is designed to help businesses in specific verticals drive sales and customer loyalty through a WhatsApp AI agent and automation.

The prototype was built in Lovable, with most of the frontend done and half of the backend in place. You would take it through to production, own engineering across backend APIs, integrations and technical support, and work closely with me on the product towards a September- October beta launch.

What we are looking for:

• Are a senior AI/full-stack developer
• Must have taken a product from 0->1 and launched it with real users
• Must have worked on WhatsApp Business API and have a thorough understanding of their compliance
• Have experience with AI agents or chatbot configuration 
• Are comfortable with sprint planning and backlog ownership.
• Are commercially minded, communicative and understand the importance of keeping the wider team aligned through clear visibility into development
• Have experience in healthcare or another regulated industry — a bonus, but not essential

This is an equity-based technical co-founder opportunity, starting with a trial focusing on technical implementation. If it goes well, it will broaden to wider company responsibility. I'm not only looking for technical competency also someone whom I can have a pleasant time working together.

If this sounds interesting, please send me a dm and let's chat!

I’m exploring a HealthTech startup focused on preventive health and regular home diagnostics.

The idea is to make it easier for people to keep track of their health reports over time and stay consistent with their routine health checks, including convenient home sample collection.

I’m currently looking for a co-founder with experience in:

• Diagnostics / pathology
• Home sample collection
• Healthcare operations
• HealthTech
• Healthcare partnerships

Having existing connections with diagnostic labs, phlebotomists, or healthcare providers would be a big plus.

I’m looking for someone who wants to build and validate the idea together, not just work as an employee or freelancer.

If this interests you, feel free to DM me and we can discuss the idea further.

Hello, I'm building a discovery led platform-sorry can't talk much about it here. Looking for a genuine techie who can build this platform from scratch. I am not from a tech background so I have no idea how much will this whole project cost me for now. Open to working with freshers, students who are serious about building an MVP from scratch.

Just to give a little context- met with a very known and famous Indian investor (portfolio worth 600 Cr) last week and took him through this idea of mine and he loved it. As per him the idea is very different & unique and not the usual pitches he gets.

So anyone who is ready to build something for India and take it the world, this is your chance.

Happy to offer equity :)

Let's build something great together.Cheers!

Kindly DM

NO AGENCIES! No freelancers. No consultants.

If you know a product person who could be interested in this — please forward 🙏

Searching for a late cofounder to own product management.

Product is a marketplace in tourism.

It is fully bootstrapped and has $6k MRR, growing.

There is no strict plan to raise funding, but we are in touch with VCs and will raise when the moment is right.

Compensation: 15% equity with standard vesting, plus a share of all revenue growth from the day you join. There is no base salary — current revenue goes back into growth. So: the upside you create is yours to share in, from day one. This is for someone who wants ownership, not a job.

If you

1. want to take ownership,
2. want to work with people you like,
3. want to work on something you believe in.

This person should be biased towards action and comfortable talking to users every week. Please ask yourself if you're financially and emotionally ready for that journey. More info will only be provided to people who are.

Have a fantastic day guap@s

TL;DR: I’m building a specialized customer-acquisition agency for a massive, established market. I’m looking for a technical co-founder who can architect the systems behind prospecting, communication, sales automation, and AI. This is equity-first with no initial salary, can begin flexibly, and could develop into a full-time role.

The agency will use technology to create a repeatable customer-acquisition engine across lead sourcing, research, outreach, qualification, follow-up, and sales.

The technology stack has not been predetermined. I want a technical co-founder who can objectively decide what should be built, what should be integrated, and where existing platforms are better than custom software.

I’m not naming the market publicly, but I’ll share the opportunity and go-to-market thesis early in a private conversation.

I bring the business and marketing vision and will lead sales, customer development, and growth. I’m looking for a technical counterpart who can turn the vision into a dependable, scalable system.

Relevant experience could include:

- CRM, marketing automation, or sales-automation architecture

- Multichannel workflows involving email, SMS, calling, and other communication methods

- APIs, webhooks, OAuth, databases, data pipelines, and third-party integrations

- Practical AI and LLM workflows for research, personalization, qualification, and next-best actions

- Custom development, low-code platforms, or a thoughtful combination of both

- Building reliable, reusable systems rather than fragile one-off automations

- Evaluating build-versus-buy decisions based on cost, speed, flexibility, and long-term scale

The right person will think like an owner. You should be willing to challenge weak assumptions, run experiments, talk to customers, and care about the business model—not just the technical requirements.

To be completely transparent: this is not a salaried developer position. It is also not an invitation to perform months of free work in exchange for a vague possibility of equity.

We would first determine whether we have genuine founder fit. Before substantial development begins, we would document equity, vesting, responsibilities, decision rights, IP ownership, expected commitment, and the path toward working on the business full-time.

If this sounds more interesting than another development or automation project, send me a DM answering these five questions:

1. What is the most complex customer-acquisition, sales, or automation system you have personally built?

2. How do you decide when to use an existing platform versus building something custom?

3. What experience do you have connecting multiple communication channels and data sources?

4. What practical AI or LLM workflow have you deployed?

5. Why do you want to become a founder, and how much time could you realistically contribute over the next three to six months?

Please also include your time zone and a LinkedIn profile, portfolio, GitHub account, or other example of your work if available.

You must be in the US. I’m happy to do zoom demos for what we are building but we are rushing to launch as fast as we can. We are targeting 100 users 6 weeks after launch. I’ll personally sell to my network. Let’s meet if you’re in the US. If you can really, really design. If you are a cracked designer who can code, let’s chat. The rest of the team is in place. We move fast but given the compliance heavy nature of things we need to plan. Attention to detail is key, you should know how the product makes you feel and be hyper vigilant of the minor details that impact the full page.

I’ve posted on here a bunch, long story short we are building Jarvis for your home.

Let’s do a google meet for 30 minutes and see how we like each other.

Hello everyone i have been into this space for more than 6 months i did a campaign with a Streetwear brand with few micro influencers then stopped it for a while and now i have restarted it again and i'm looking for a co founder who have good experience in influencer marketing and help me to scale my agency further.

Some skills that he must have is:

1. He should he able to speak fluently English and hindi.

2. Have good negotiations skills.

3. Can help me to get new clients.

I'm ready to put time into this if you have time issue you just have to guide thoughout the journey.

Interested people please connect.

I am looking for some form of assistance or investment in putting up a Software Development and AI Engineering company. I have implementations and Revenue model set. So all I need now is a working Capital.
Target Market will be North America, Australia, and the UK. Products will be Web apps, mobile apps, API, Portals, websites and shopping carts.
AI implementation and Automations too.

It would mean so much if anyone can help. This will help me and many people because I spread out the blessings I get. Never a selfish person. I always believe that if there’s a will. There’s a way.

Do not hesitate to reach out.

I’m a full-stack/backend-heavy developer from India, and I’ve just made the decision to leave my job.

I’ve spent the last few years building production systems rather than just tutorial projects — everything from AI products and SaaS platforms to distributed backend systems and an international multivendor OMS.

One of the projects I worked on was in a pretty rough state when I joined. After around 10–11 months, it was only about 10% complete. I took ownership of the backend architecture and core workflows, restructured the system, and helped get it delivered in roughly 6 months.

Technically, I’m comfortable owning the entire stack:

• Next.js / React / TypeScript
• Node.js / NestJS / Express
• PostgreSQL / MongoDB
• Redis / BullMQ / Kafka
• AWS / Docker / cloud infrastructure
• Authentication, RBAC, APIs, distributed systems
• AI/LLM integrations
• Building products from 0 → production

I’ve also built products like an AI transcription platform, a multi-LLM platform, deployment tooling, e-commerce systems, and other SaaS applications.

What I don't want is another job.

I’m looking for a cofounder.

I want someone who is strong on the other side of the equation — product thinking, customer discovery, sales, growth, business development, marketing, partnerships, or a combination of those.

You don't need to come with a million-dollar idea.

I’m much more interested in finding someone who is hungry enough to spend the next few years figuring out a real problem, validating it, and building something people actually want.

I’ll own the technical side completely.

You should be comfortable owning the business/customer side.

I’m open to starting from zero, validating ideas together, killing bad ideas quickly, and going all-in on the one that makes sense.

This would be an equity/founder conversation, not a freelance project or employment opportunity.

Remote is completely fine. I’m based in India (IST).

If you're serious about building a company rather than just talking about startups, DM me.

Tell me:

1. What you do
2. What you're exceptionally good at
3. What you've built or sold before
4. What kind of company you want to build

Maybe we build something together.

Maybe we realize we're not the right fit.

Either way, I'm ready to start.

I have an idea I'm working on, broadly forecasting and optimization for small teams. I won't lay out the whole thing here, but I'm happy to get into specifics once we’re talking.

Nothing is built right now. I want to validate this by talking to people actually living the problem. If you join now, the first weeks are discovery and validation.

About me: 28, technical, been programming since I was a kid. Most of my work lately has been done in systems languages, C++ mostly. I’m strongest in product, architecture, and tooling.

What I'm looking for:

1. Someone math-focused: A quant background isn't required, but it's a plus. More importantly, you should be comfortable with math and willing to dig into whatever's needed.

2. Someone sales-focused: Not traditional sales at first. Think early discovery, talking to potential users, figuring out pain points, and looping the team in on what you're hearing.

This is a serious attempt. Not a guarantee it'll work out, but the general shape of the plan is to set us up for success. Ideally you're someone who could go full-time if things get to that point. I'm open to people from anywhere, but we'd need the logistics to be workable.

I’m looking for people who like to problem solve from ground zero rather than be handed a spec, think borderline research problem.

If this sounds interesting, DM me, tell me a bit about yourself, what you've built/worked on, and what kind of team you want to build. I'm going to read every DM, might not reply to all of them, but I'll read every single one.

All the best.

I'm looking for a Founding Full-Stack Engineer to join at a very early stage.

Not looking for someone who just wants another developer job. Looking for someone who wants to build, take ownership, and grow with the company.

Remote

High equity

No fixed salary currently

Part-time / Full-time

Full technical ownership

Potential CTO / Technical Co-Founder

Strong engineering skills matter. Previous startup experience doesn't.

I have recently come up with good idea, but i think my knowledge in marketing is not enough to grow this product. So i am looking for a teammate who can help me with growth and sales part. I am absolutely ready to contribute into marketing also, but i can do that correctly only by your help. I am a software engineer with 5 years of experience and im going to build product fully myself you do not have to worry about it. Before starting to build it we have to verify the idea to make sure it is worth working on. Thank you for attention guys!

Building a Digital Nomads Startup Community in Bangalore - Expanding to Goa

Hi everyone,

We are building a Digital Nomads Community in Bangalore, focused on bringing together founders, entrepreneurs, freelancers, creators, remote professionals, and people building meaningful businesses.

Our community has already grown to 250+ members, and we are now planning to expand the community to Goa.

We are looking to connect with individuals, founders, community builders, businesses, and potential partners who are interested in collaborating with us to build and grow the Goa chapter.

Potential areas of collaboration include:

- Community building

- Startup and founder networking

- Events and meetups

- Business collaborations

- Partnerships

- Workshops and knowledge-sharing

- Supporting digital nomads and remote entrepreneurs

If you are based in Goa or planning to build something within the startup, entrepreneurship, remote-work, or digital-nomad ecosystem, we would be interested in connecting.

If this interests you, please DM me and let's explore how we can collaborate.

I’m 22. My friend and I talk business pretty much every day, and honestly it’s just the two of us in there so far. It’s been useful, but it’d be a lot more useful with a few more people who aren’t each other.

On my end, I can handle most of what a small company needs. Coding in Python, HTML, web design, app design and development, content creation, shooting and editing, plus the finance, business and operations side. So I’m not turning up empty handed looking for someone to do the work.

I’ve also got a few ideas of my own that I’m already working on and could genuinely use help with. And if you’ve got ideas you want to bring, I’m just as happy to put work into those.
Ideally you know your way around AI, or at least really want to learn it. A lot of what I’m building leans on it. I’ve got money to put in on my side, so if we end up building something together we wouldn’t be starting from nothing. Not looking for gurus or anyone selling a course. Just people who want somewhere to think out loud and maybe find a cofounder out of it. Comment or DM me and I’ll send the link. Or just join in my bio
