What I've learnt recruiting 50+ grassroots co-founders

In my five years at Founders Factory, I've led on hiring for over 50 co-founders for our venture studio concepts across multiple continents and industries. The assessment framework we use is deliberately designed to cut through the noise of CVs and surface the things that actually predict founder success. I want to share how it works, because I think any early-stage founder can adapt it for their first hires.

We assess on four dimensions, and domain expertise isn't the first one

For every founder-candidate, we evaluate against four core questions.

1. What gives this person the unfair advantage to build THIS business?

This is the most important question, and it's a different question to "do they know the industry." An unfair advantage might be lived experience with the problem (not just professional exposure to it), a rare combination of skills from adjacent sectors, a network that unlocks distribution, or a technical capability that's directly relevant to the product thesis. The best founder for an AI-native insurance venture, for instance, might not be someone who's spent 20 years in insurance. It might be someone who's built algorithmic products in a similarly regulated industry and can credibly sit across from a corporate partner's CUO while also shipping code.

What we're really asking is whether this person has something, be it experience, insight, network, or obsession, that would be genuinely difficult to replicate. If the answer is "they know the sector well," that's a start, but it's not enough. Sector knowledge can be hired for. Founder-grade conviction and capability cannot.

2. What makes this person emotionally connected to the concept? Why this, and why now?

Here is where we probe for intrinsic motivation, and it's the dimension most hiring processes miss entirely. We want to understand whether this person has been independently circling this problem. Have they been sketching solutions in their spare time? Are they at a genuine inflection point in their life where going all-in on something ambitious feels not just possible but necessary?

The strongest signals I've seen are candidates who've arrived at essentially the same thesis as our venture concept before they even saw the brief. When someone demos a quick proof-of-concept on the first call, not because we asked but because they couldn't help themselves, that tells you more about their likelihood of success than any CV line ever could. Equally, we look for honest answers about timing. Someone who's quick to quit their full time job to commit, who’s already spoken at length with their partner about the enormous support they’ll need, and who's ready to commit fully. Founders who are half-in rarely succeed.

3. What are the flags, and are they manageable?

Every candidate has gaps. The question is whether they're the kind that can be supported or the kind that will sink the venture. Limited fundraising experience? We can coach that. "Too nice" to make hard commercial calls? That needs probing, because the role will demand it. A conservative instinct around financial planning in a context that requires aggressive pace? That tension needs to be named and tested.

We structure references specifically around these flags. Rather than asking generic questions, we ask the referee's perspective on the exact risk we've identified. "How does this person respond when things go badly?" and "Would you choose to build or work with them again?" are worth more than any professional endorsement.

4. What type of co-founder do they need beside them?

This is where the "hire for drive" thesis becomes operationally concrete. We're not looking for a single individual who can do everything. We're looking for someone whose strengths are clear enough that we can define precisely what the complementary co-founder profile should be. The strongest candidates are self-aware about where they're exceptional and where they need a partner. A CEO founder with deep commercial instinct and stakeholder credibility but limited technical depth needs a CTO who can build at scale. Getting this pairing right is as important as getting the individual right.

The patterns that predict success

Having run this framework across dozens of ventures and hundreds of candidates, some consistent patterns have emerged.

The strongest founders often come from adjacent, not identical, backgrounds. Cross-pollination of experience is a feature, not a bug. Someone who's built and scaled a product in a similarly complex, regulated environment often outperforms a pure industry insider because they bring fresh perspective without the anchoring bias of "how things have always been done."

The best signal of drive is what someone does before they're asked. The candidate who builds a prototype before the first call. The one who sends a follow-up email with three ideas for GTM before you've even discussed the role in detail. The one who asks questions about the venture's biggest risks rather than the compensation structure. These behaviours are diagnostic. They tell you how this person will operate on day one.

References should be structured around specific risks. When we call a referee, we already know what we're worried about. We ask them to speak directly to that concern. This transforms references from a box-ticking exercise into genuine signal.

The bottom line

The market is moving towards a clear consensus. In high-growth, early-stage environments, drive beats domain. The companies scaling fastest are all, in different ways, hiring for motivation, adaptability, and raw capability over industry credentials.

Intrinsic motivation is harder to assess than years of experience. But it can be assessed, systematically and rigorously, at the point of hire. And the people most traditional processes overlook are often the ones who end up building the most remarkable companies.

Your first five hires define your culture. Make them count.
