r/StartupAccelerators

Unusual background: I've spent my career in professional kitchens in Switzerland. Nights and weekends over the last two years, I taught myself software engineering and built a production-grade algorithmic trading platform for crypto perpetual futures — full order management system, VaR/CVaR risk engine, portfolio allocator, 500+ tests under strict TDD, and a fully local AI stack (nothing leaves the machine — a deliberate data-sovereignty angle for the Swiss B2B clients I'm targeting, like family offices).

The system runs and has out-of-sample results. What I don't have: a co-founder, a network, or fundraising experience. I've hit the ceiling of what one person can do alone, and I want to go from "solo builder with a working MVP" to a pre-seed-ready startup.

Questions for people who've walked this path:

1. Which accelerators are genuinely worth it for fintech/quant infrastructure — and which accept solo founders? (I know YC does in theory; what about Tenity, Techstars, or other Swiss/EU programs?)

2. For a trading-tech product, is an accelerator even the right move vs. building a live track record and going straight to angels?

3. What do pre-seed investors actually need to see from a trading-tech company — audited performance, first paying client, regulatory clarity?

4. Solo founder in fintech: dealbreaker, or manageable if the tech and traction are real?

Not selling anything, not sharing signals. I'm not looking for validation — I'm looking for the map. Brutal honesty welcome.

Hi everyone!

I'm working on a small developer tool, and before I build more features, I'd rather understand how people actually use AI day to day. If you're using tools I'd love to hear about your experience. A few things I'm curious about:

- What's your typical AI workflow?

- Do you ever paste logs, stack traces, or config files into AI?

- Have you ever worried about accidentally sharing something sensitive?

Is there anything about your current workflow that feels annoying or risky?

I'm not looking to pitch anything I genuinely want to learn from people who use these tools every day. Every reply helps me understand the problem better.

Based on public analysis, solo founders have acceptance odds that are roughly five times lower than founding teams.

But after looking through founders who beat those odds, I noticed they share a few characteristics that make the "solo founder" label much less relevant.

1. They had already built products people actually used.

Not just startup experience or the ideas. They had a track record of shipping products into the hands of real users. MagicBell's Hana Mohan had spent nine years building products before YC. Mattan Griffel had already launched multiple products before creating One Month Rails.

2. Their traction was unusually strong for one person.

Not "I have a few hundred users."

More like:

• MagicBell was delivering 1M+ notifications every month before YC.
• One Month Rails already had 2,000+ students.
• Anja Health already had paying customers, despite being built with contractors.

The common pattern was traction that looked difficult for a single founder to achieve.

3. They knew their customers inside out.

Because they were doing every demo, every support conversation, and every sales call themselves, they could explain customer problems with a level of detail that's hard to fake. Being solo had become an advantage because it forced them closer to the customer.

4. They answered the "team" question with a plan, not an argument.

None of them tried to convince YC that solo founders are better. Instead, they had a clear idea of who they'd hire next, what skills they were missing, and how the company would grow beyond one person.

My takeaway isn't that YC doesn't fund solo founders. The average solo founder is competing against teams.The solo founders who get accepted often look like they've already accomplished what an early team would normally accomplish together.

If you're building solo, where do you think your evidence is strongest? Is it your product, your traction, your customer knowledge, or something else? & what is that..

We all know the pain — you pour weeks into your pitch deck, send it to dozens of investors, and get... crickets. Or the classic “not the right fit right now” with zero explanation.

No insight into what actually landed, what confused people, or what red flags killed your chances.

So I’m curious — how are other founders getting useful feedback on their pitches?

• Cold outreach to investors?
• Friends & family (brutally honest ones)?
• Accelerators / incubators?
• Paid coaches / consultants?
• Online communities or “roast my deck” threads?
• AI tools?
• Something else?

What’s worked best for you? What hasn’t? Any horror stories or game-changing moments where feedback completely leveled up your deck and fundraising?

Would love to hear real experiences (especially from anyone who’s recently raised or iterated multiple times).

Thanks in advance!

(For context — I’m building something to help close this exact feedback gap, so all input is gold.)

We launched the first version of Hackyard about a week ago.

We had a lot of features. Twitter-style feed, public build logs, weekly ship reports, builder profiles, bookmarks, notifications, DMs, reputation system, founding member badges. We threw in everything.

Then we started talking to people. Got about 200+ replies across Reddit, email, and LinkedIn.

I kept waiting for questions about growing an audience or getting funding. Barely anyone brought that up. The actual messages were things like "how do I find customers," "I need a technical co-founder," "know any good designers," "I need someone who knows sales," "I just want to meet builders working on similar shit."

Made me stop and think.

We'd accidentally built this thing that was part LinkedIn, part Twitter, part GitHub, part Discord all smushed together. Nobody came for another social network. They came because we'd put one sentence on the page: find the people you need to build with.

So we started ripping stuff out.

We killed the idea that the feed was the product. Stopped caring about posts and likes and doomscrolling. Onboarding used to walk you through everything. Now it's two fields: what are you building, who are you looking for.

Profiles are slowly becoming proof of work instead of resumes. The feed is becoming a discovery tool instead of engagement bait. We're rewriting the algorithm to surface introductions and collaborations, not whatever keeps people clicking.

If you're building something and you need a co-founder, first engineer, designer, researcher, operator, beta users, or early customers, we want Hackyard to help you find them faster. That's the point. Everything else can wait.

We've got about with all founding members and we're actively rebuilding big pieces of the product based on what they told us. It honestly hurts to delete features we spent days on. But I'd rather ship one thing people actually need than ten things nobody asked for.

For anyone else building in public: what would make a network like this something you'd actually come back to every week?

Lately I've been trying to put together a list of really early-stage startups, and it's been more frustrating than I expected. Every recommendation seems to lead back to the same places. Apollo, LinkedIn, Crunchbase, Product Hunt after a while it starts feeling like everyone is looking at the exact same companies.

By the time a startup shows up on those platforms, I kind of assume they've already had dozens of sales emails sitting in their inbox. What I actually want are the companies that are still under the radar. The ones that have just registered the business, quietly launched a website, or started hiring before they've made much noise.I stumbled across AtlasForgeX while looking into this because it apparently builds lists from public records instead of a stored database. I haven't used it enough to know if it's actually better, but it did make me wonder if I've been searching in the wrong places this whole time.

Curious how other people here do it. If you're trying to find startups before they're on everyone's radar, where are you actually looking?

Employees belonging to legal, and Finance are not technically advanced and are prone to share sensitive and client related data AI models.

Employees are given access to ChatGPT and Claude but they are sharing sensitive information, emails and files to AI for quick help. We don't have any audit and usage patterns for the employees. How to track the usage of AI models from such employees.

trust me.
investors who already funded something in your space dont need the market explained, they already believe in it.
so instead of educating cold investors from zero, i went straight to the ones who’d backed competitors or adjacent companies. the only work was figuring out who those people actually were, which angels and funds had checks in companies like mine. once i had that list, the conversations were 10x faster because they got it in the first sentence. find the people already convinced of the problem, and you only have to sell them on you.

Founders, how do you currently keep track of things that could impact your startup?

• Competitor launches
• Product Hunt launches
• Funding rounds
• Customer discussions on Reddit/X
• Market shifts

Do you actively monitor these, or mostly ignore them?

I'm exploring an idea where founders describe their startup once, and the system alerts them when something materially requires attention.

Examples:

• Competitor launches a feature → Ignore
• Three competitors raise prices → Alert
• Customers suddenly complain about the same issue across Reddit → Alert

Would something like this be useful, or do dashboards/newsletters already solve the problem for you?

(Just validating the idea before building.)
