In short. A startup is VC-compatible if it can credibly grow large enough to return, on its own, the fund that backs it. This test depends as much on the size of the fund as on your project. Before any first contact, check this arithmetic, then target the investors whose model matches yours.

Why most startups should not raise from VCs

A good startup is not necessarily a VC-compatible one. Many profitable, growing and well-run companies will never fit a venture capital fund's criteria, and that is not a failure: it is a question of business model, theirs and the fund's.

The stakes are all the more concrete as funds are investing less often. According to our European Tech Fundraising analysis, French startups raised €6.4bn in 2025 across 506 deals, 29% fewer deals than in 2024. Fewer rounds means more selective investment committees.

This guide gives you the test funds run, the four criteria they really assess, and a method for choosing which investors to contact, VC or not.

What does being VC-compatible mean?

Being VC-compatible means credibly aiming for an exit large enough to return, on its own, the entire fund that finances you. It is not a judgment on the quality of your company, but on its possible place in a portfolio.

The power law: why funds look for outliers

Venture capital returns follow a power law: a handful of investments generate most of the gains, and most of the others lose all or part of their stake. According to Horsley Bridge data analyzed by a16z, about 6% of investments, representing 4.5% of the capital invested, produced nearly 60% of total returns.

The direct consequence: a fund cannot settle for a company that will "3x". It needs every position to have at least a real chance of becoming the fund returner, the investment that returns the entire fund.

The 4 criteria a fund really assesses

A venture capital fund assesses four things: the size of the opportunity, the model's ability to grow without costs following, the team, and what will stop a better-funded competitor from catching up. Each is proven with facts, not claims.

1. A market that matches the target exit

There is no universal threshold for the addressable market: it must be consistent with the exit value the fund needs. If you are aiming for a €1bn valuation, the market must allow you to reach, with a realistic share, revenue of about €100m or more. Build this estimate bottom-up (number of target customers × average contract value), not by quoting a global market report.

2. A model that scales

Scalability shows in the numbers: gross margin, customer acquisition cost, retention, ARR per employee. The analyst expects you to know them without checking your notes, and above all to be able to explain how they evolve. A model that requires a new hire for every new customer is not scalable, however fast it grows.

3. A team with an edge in this market

Funds are not looking for prestigious profiles, but for founder-market fit: a specific reason why this team will win in this market (domain expertise, customer access, rare technical skills, prior entrepreneurial experience). The ability to hire people better than yourself is the second most scrutinized signal.

4. An advantage that strengthens over time

In Zero to One, Peter Thiel identifies four sources of durable monopoly: proprietary technology, network effects, economies of scale and brand. A fund will ask you which one you are building, and what makes it stronger with each customer won. "We move faster" is not a defensible advantage; it is a head start.

The Breakline view

The most frequently mispresented criterion is not the market, it is the defensible advantage. Founders describe what they do better today, whereas the fund wants to know why the gap will widen tomorrow. If you cannot explain in one sentence what makes your position stronger with each new customer, rework this point before building your fundraising equity story.

Key takeaway: rate yourself honestly from 1 to 5 on each of the four criteria. Below 3 on any of them, the question is not yet which funds to choose, but how to strengthen that point.

Which investors should you contact for your raise?

The right investors to contact are those whose stage, ticket, thesis and fund size match your project, and who can follow on at the next round. A list of 300 funds sent blindly yields less than a selection of 30 well-qualified funds.

The 6 filters to qualify a fund

1.       Stage. A Series A fund will not do your pre-seed, even as a favor. Check the latest rounds it has led, not the description on its website.

2.       Ticket. Your amount should fall within its usual range, ideally in the middle.

3.       Thesis. Sector, model (SaaS, marketplace, deeptech), geography. A fund that already has a direct competitor in its portfolio will not back you.

4.       Fund size. It sets the exit value the fund needs to return its capital.

5.       Follow-on reserves. A fund that reinvests in its portfolio companies is an asset at the next round, because moving from one round to the next is selective. According to benchmarks published by Carta, seeing 25% of its seed startups raise a Series A within two years is a median rate for a US fund.

6.       Role. Lead or follower? You need a lead first, who sets the terms and brings the others along.

If you are not VC-compatible: the alternatives

Key takeaway: build a list of 30 to 50 investors, ranked in three waves by fit. Contact the second wave first to refine your pitch, and keep the first wave for when it is sharp.

When and how to contact a fund for the first time

The right time to contact a fund is three to six months before your raise, to build a relationship, not to ask for money. A first contact in the middle of a raise, with no history, is the hardest to convert.

Before the raise: establish a trajectory

An investor judges a curve better than a point. Get in touch a few months ahead, share two or three updates with numbers, then come back with your round: they will have seen you deliver on your commitments. It is the best argument you can give them.

During the raise: prepare before you send

•         Go through an introduction. A founder from its portfolio, a mutual business angel or an advisor it knows: a qualified intro gets read, a cold email far less often.

•         Have your documents ready. Pitch deck, financial model and data room must be consistent before the first meeting, not after.

•         Calibrate your valuation assumptions. Come with market references, for example those in our report on European tech fundraising.

•         Group your meetings. An efficient raise concentrates first meetings over a few weeks, to build momentum and compare offers.

Key takeaway: a fund does not forget a bad first meeting. Do not waste your best targets on a version of your pitch you have not yet tested.

FAQ: VC-compatible startup

How do I know if my startup is VC-compatible?

Run the fund-returner test: estimate your company's plausible exit value in 7 to 10 years, then divide the size of the target fund by the stake it would hold at exit. If your exit value credibly reaches that threshold, and you are strong on market, scalability, team and defensible advantage, you are compatible with that fund.

What market size do you need to interest a VC?

There is no universal threshold. The market must allow revenue consistent with the exit value the fund requires, with a realistic market share. For a fund that needs a €1bn exit, this generally implies revenue of around €100m or more. A bottom-up estimate is more convincing than a figure from a global report.

How many funds should you contact for a seed round?

A list of 30 to 50 well-qualified investors is generally enough, ranked in waves by fit. Beyond that, targeting quality drops and the risk of your deal circulating without momentum increases. What matters is the share of relevant funds, not their number.

Can you raise money without a VC?

Yes. Business angels, family offices, corporate funds, Bpifrance financing and debt can fund growth that does not fit the venture capital model. For a profitable or near-profitable company, these sources are often less dilutive and leave more freedom on the exit horizon.

Conclusion: choose your investors before they choose you

Being VC-compatible is not a label; it is a fit between your possible trajectory and the business model of a specific fund. Run the fund-returner calculation, assess yourself honestly on the four criteria, then target a short list of genuinely aligned investors. A successful raise starts with the right selection, long before the first pitch.
