The Problem

Solo founders consistently struggle to find trustworthy, complementary co-founders. Existing channels like LinkedIn feel too formal, Reddit is random, and hackathons are rare and location-dependent. Non-technical founders especially lack reliable ways to connect with technical partners who share their vision and commitment level.

Potential Solution

A dedicated matching platform that pairs founders based on complementary skills, work styles, industry interests, and commitment levels. The app uses verified profiles, compatibility algorithms, and structured trial collaboration periods so founders can test working together before committing. Built-in tools for equity discussions, role definitions, and co-founder agreements reduce early partnership friction.

Why Now?

The explosion of AI-assisted building tools has empowered more solo founders than ever to start projects, but they hit scaling walls that require partners. Remote-first work culture has also made geographic barriers irrelevant, vastly expanding the potential co-founder pool if the right matching infrastructure exists.

Community for people wanting to build together!

Hi all, I recently launched **Cofounnder** \- [cofounnder.com](cofounnder.com) \- a platform and community for people looking for a co-founder, mentor, accountability partner, wanting to meet other ambitious people, or just looking for someone to explore an idea with. There are already people on there with variety of skills, ideas and backgrounds. Our the goal isn't only to help you find someone but give you enough evidence to make an informed decision. You set out what you bring and what you're looking for - skills, experience, how much time you can commit, location, proof of work, progress - and see the same back from everyone else. Once you connect, you can run **Alignment Check**. You both answer the same questions without seeing each other's answers, and they're only revealed once you've both finished. It covers commitment, goals, decision-making and how you'd handle disagreements. From there you can interview each other in writing (we have a set of questions but you can change them how you like), work through equity, and sign a mutual NDA and a partnership agreement you both keep as PDFs. There's also an Idea Lab if you're still shaping what you want to build, and a toolkit for the company setup admin. If you're looking for a co-founder, have an idea to explore, or just want to meet people who are building, have a look. Would be great to see some of you join :)

Looking for a partner

I’m looking for someone who complements me. My strength is on the product and AI side. I work in enterprise AI and AI governance, and I’m comfortable taking a problem from an initial idea to a working prototype or MVP. I can figure out the product, build quickly with AI tools, test different approaches, and handle a lot of the strategy and execution behind the scenes. Where I’m not naturally strongest is constantly networking, opening doors, building a pipeline, and selling. I can do those things when needed, but I know a business will have a much better chance if I partner with someone who genuinely enjoys and excels at the commercial side. I’m looking for someone who is good at: Speaking with potential customers and understanding what they will actually pay for Building relationships and partnerships Finding creative ways to distribute a product Selling B2B products, software, or services Turning conversations into pilots and paying customers Staying persistent when the first few approaches do not work I have several ideas around AI, enterprise workflows, regulated industries, risk, compliance, governance, and cybersecurity. But I’m not attached to forcing one of my ideas through. Ideally, we would look at the markets and people we each have access to, identify a real pain point, speak to potential customers, and decide together what is worth building. I’m not looking for someone who only has ideas, wants me to build everything, or describes themselves as a “growth hacker” without having actually sold anything. At the same time, I’m also not expecting someone to immediately quit their job or commit to a company after one conversation. I think the sensible way to start is to work together on a small, focused experiment for four to six weeks: Pick one specific customer problem. Speak with potential users or buyers. Build a basic version quickly. Try to get a paid pilot or strong evidence that people want it. See whether we act...

Looking for technical co founder to build something for cofounders

I've been thinking a lot about why co-founder matching is broken. Most platforms are one-sided... technical founders browse profiles like a job board, or non-technical founders post ideas and wait for someone to apply. Both miss the point. Real partnerships form when two people independently choose each other based on mutual fit, not when one person pitches and the other evaluates. So I'm building Mock Draft. Dual preference co-founder matching where both sides set their preferences anonymously before either sees the other. A match only happens when both people independently signal interest. No public rejection. No pitching into a void. Anonymity removes bias so you evaluate based on values, work style, communication, and what you're actually building together... not name, photo, or school. Why I'm building this: co-founder breakups are the #1 startup killer, and most happen because of misaligned expectations, values, or working styles... not skills. Dual preference forces alignment BEFORE introduction. And as someone who's been through recovery and built in mental health, I know how much anonymity matters when you're putting yourself out there vulnerably. Looking for a technical co-founder to build this with me. Here's what I bring as the GTM side: \- 10+ years in tech sales and business development across SaaS, security, and healthcare \- Deep network of founders, investors, advisors, and operators through Boardy partnerships \- Experience taking products from zero to early traction through founder-led outbound and community building \- Background in partnership sourcing, demand gen, and account management across multiple industries What I need from you: \- Ability to build MVP and iterate fast \- Comfort with privacy-first architecture (anonymity is core, not optional) \- Interest in solving human connection problems, not just tech problems \- Work style and communication that...
