Founding a startup alone is possible. But the data is clear: startups with two or more co-founders raise more money, grow faster, and are less likely to fail than solo ventures. Having a complementary partner means someone to share the weight on hard days, challenge your assumptions, and cover the skills you lack.

The challenge is finding the right person. And in Switzerland — where the startup ecosystem is tight-knit but not enormous — knowing where to look makes all the difference.

This guide covers exactly that: how to find a co-founder in Switzerland, what to look for, and how to structure the relationship once you find them.

Why the right co-founder matters so much

Before you start looking, it is worth being clear about what you actually need. Many founders make the mistake of searching for someone who thinks exactly like them. That feels comfortable — but it is rarely what the startup needs.

The most effective founding teams tend to combine at least two of these profiles:

• The Builder — someone who can build the product. Technical skills, engineering mindset, ability to execute on the product side.
• The Seller — someone who can find customers, close deals, and communicate value. Commercial instinct, network, and hustle.
• The Expert — someone with deep domain knowledge in the industry the startup operates in. Often critical in regulated or technical sectors like medtech, fintech, or energy.

Ask yourself honestly: which of these are you? Then look for someone who fills the gaps.

1. Start in your immediate network

The best co-founding relationships often come from people you already know — or know one degree away. Before you go looking at strangers, work through your existing network systematically.

Think about former colleagues, university classmates, and people you have worked with on projects. Who impressed you with how they think? Who do you know that has the complementary skills you need? Who do you respect and trust enough to go through a hard journey with?

A short, honest message goes a long way:

“Hi [Name], I’m working on a startup idea in [space] and I’m looking for a co-founder with [skills]. I’ve always respected how you think about [X]. Would you be open to a coffee to explore whether there might be a fit?”

Even if the person is not the right fit, they may know someone who is. Do not underestimate the power of warm introductions.

2. Go where founders gather in Switzerland

If your immediate network does not produce the right person, the next step is to put yourself in rooms where other motivated founders and future founders spend time.

University entrepreneurship communities

Switzerland’s universities are an excellent source of technically strong co-founder candidates. The ETH Entrepreneur Club, EPFL’s Innovation Park, ZHAW’s entrepreneurship programs, and the University of St. Gallen’s student startup community all have active communities of people who want to build companies.

If you are not currently affiliated with a university, many of their events are open to the public. Show up, participate, and be genuinely curious about what other people are building.

STARTUP CAMPUS events and programs

The STARTUP CAMPUS Co-Founder Matchmaking events are designed specifically for this. They bring together founders at various stages who are actively looking for complementary partners — structured around making real connections, not just networking.

The Business Concept Course is also one of the best places in Switzerland to meet a co-founder organically. Over 12 weeks, you work closely with a cohort of 25 other motivated founders. You see how people think, handle feedback, and work under pressure — all of which tells you far more than a coffee chat ever could.

Community spaces and coworking hubs

Places like Impact Hub Zurich, Technopark Winterthur, and the Büro Züri Innovationspark attract early-stage founders and bring together people from different professional backgrounds who are building or thinking about building a company. Simply being present and visible in these spaces over time leads to connections.

3. Use online platforms — but use them well

Several platforms exist specifically for co-founder matching. They can work, but the quality of your results depends almost entirely on the quality of your profile and outreach.

Platforms worth trying:

• YC Co-founder Matching — Y Combinator’s free platform is surprisingly active and globally used, including by Swiss founders
• CoFoundersLab — one of the larger co-founder matching communities
• LinkedIn — underrated for this. A clear post explaining what you are building and what you are looking for can generate strong responses, especially in the Swiss startup community

How to write an effective profile or post:

Do not just say “looking for a technical co-founder.” Be specific about what you are building, why you are the right person to build it, and exactly what you need.

A good co-founder post looks like this:

“I am building a B2B SaaS product for Swiss HR teams that automates onboarding for international hires. I have 8 years of HR experience and 3 reference customers already lined up. I am looking for a technical co-founder with experience in SaaS product development who wants to build something real. We are pre-funding and I am open to equal equity split for the right person. Based in Zurich.”

That is honest, specific, and gives a potential co-founder enough to decide whether to respond.

4. Work together before you commit

Finding someone who seems like the right person is only the beginning. Before you sign anything or give away equity, work together on something real.

Give the relationship at least 4 to 8 weeks of actual collaboration on the startup. This could mean working through a business model together, doing customer discovery, building a prototype, or preparing a pitch.

What you are looking for during this period:

• How do you handle disagreement? Disagreements are inevitable. What matters is whether you can work through them constructively.
• Do you share the same ambition level? A founder who wants to build a lifestyle business and a founder who wants to raise venture capital will eventually come into conflict.
• Do they follow through? Does the person do what they say they will do? Reliability is everything in a founding team.
• Is the energy sustainable? Do you genuinely enjoy working with this person, or does every interaction feel like effort?

No amount of impressive credentials makes up for a bad working relationship.

5. Get the legal structure right from the start

Once you have found your co-founder and decided to move forward, address the legal and equity conversation early. Many co-founder relationships break down not because of personality clashes but because the equity and role split was never clearly defined.

Equity split

Resist the temptation to split equity 50/50 by default. The right split reflects each founder’s contribution — experience, time commitment, idea, network, and capital invested. An equal split only makes sense if contributions are genuinely equal.

Vesting schedules

Standard practice is a 4-year vesting schedule with a 1-year cliff. This means each co-founder earns their shares over 4 years, and none vest at all during the first year. This protects both parties if someone leaves early.

Founder agreements

Before incorporating, put a simple founder agreement in writing that covers equity split, roles, decision-making authority, what happens if someone leaves, and IP ownership. A Swiss startup lawyer can prepare this for CHF 1,000 to 2,000. It is money well spent.

If you are unsure where to start on the legal side, the Business Concept Course by STARTUP CAMPUS covers IP strategy and legal basics as part of the curriculum — including what to think about before you sign anything with a co-founder.

6. Special considerations for female co-founders in Switzerland

If you are a female founder or a startup with at least one female co-founder, the Female Founders Initiative Switzerland is a strong resource for both finding the right people and getting support once your team is in place.

The community includes over 600 female founders across Switzerland, and the FF+ Acceleration Program is a free 10-week program designed specifically for co-founded startups with at least one female founder — covering investor readiness, pitch training, and fundraising strategy.

Diverse founding teams consistently outperform homogeneous ones. If you are building a team, diversity in gender, background, and expertise is not just good ethics — it is good strategy.

What to do this week

Finding a co-founder takes time. The best thing you can do is increase the surface area of your search: be visible, be specific about what you are building and what you need, and actively create opportunities to work with potential candidates before committing.

Here are three concrete steps to take this week:

1. Write down exactly what you are looking for — what skills, what time commitment, what equity structure. Being clear in your own head makes you more compelling to others.
2. Reach out to three people in your existing network who might be a fit or might know someone who is.
3. Register for the next Co-Founder Matchmaking event or Business Concept Course by STARTUP CAMPUS — both are free and designed to help you build exactly this kind of relationship.

The right co-founder is out there. The question is whether you are putting yourself in a position to find them.
