How to find a co-founder
Why you need a co-founder, where to look, how to assess candidates and what to agree before starting the partnership.
By Editorial Team
Many investors prefer a complementary founding team to a solo founder. The right co-founder brings more than shared workload: a different perspective on hard decisions and resilience in tough times. The wrong one can be a startup's biggest risk.
Why a co-founder?
- Complementary skills: a technical founder paired with someone who knows sales and business development, or the reverse
- Speed: two or three people do more than one
- Investor confidence: team risk is what early-stage investors look at most
Where to look
- Your network: former colleagues, classmates, people you have built projects with. Having worked together before is the strongest signal.
- Ecosystem events: hackathons, entrepreneurship programmes, demo days and meetups
- Incubators and accelerators: some run co-founder matching; see our incubator vs accelerator guide.
- Universities and technoparks: especially for deep tech; see our technopark guide.
- Online communities and platforms: industry groups and founder communities. A profile on Türkiye Startups makes you visible in the ecosystem.
Assessing a candidate
Skills
Does the candidate have a proven record in the area you lack? Look at their work and references.
Values and goals
- How big do you want to grow, and when would you consider an exit?
- Are you aligned on risk, pace and raising investment?
- How do they behave when a hard decision comes up?
Commitment
Can they join full-time? Can they afford a period with little or no salary?
A trial period
Before formalising, do a small, time-boxed project together: an MVP, a series of customer interviews or a competition entry. It is the best way to see how you work together. Our MVP guide is a good starting point.
Agree before you start
- Equity and vesting: earning shares over time manages early-departure risk.
- Roles and decisions: who decides what?
- Departure scenarios: what happens to shares if someone leaves?
- Intellectual property: everything built belongs to the company
See our founders' agreement guide for details.
Warning signs
- A candidate who keeps postponing going full-time
- A rigid, non-negotiable stance on equity from day one
- Avoiding clear answers to hard questions
- Having the same skills as you instead of filling the gap
Conclusion
Choosing a co-founder is as serious as a marriage. Do not rush, get to know each other by working together and put everything in writing.
