Fundraising

How venture capitalists actually decide

8 min readBy the Garage to IPO editorial teamUpdated

Founders tend to assume that venture investors are judging whether a business is good. They are judging something narrower and stranger: whether this specific company could plausibly return their entire fund on its own.

Understanding the fund arithmetic explains almost every behaviour founders find confusing — the obsession with market size, the indifference to profitability, the speed of a yes and the vagueness of a no.

The fund maths that drives everything

A venture fund raises a pool of capital and must return several times that pool over about ten years to be considered successful. Returns are wildly concentrated: in a typical portfolio of thirty companies, one or two produce most of the return, a handful return the capital invested, and the rest return little or nothing.

Because the winners have to carry the losers, each investment is assessed against a single question: if this works, is the outcome large enough to matter to the fund? A company that will reliably become a twenty-million-dollar business is a good company and a bad venture investment, and both statements can be true at once.

Why one outcome has to be enormous — a $200M fund

What they are actually assessing

Market size comes first, because it caps the outcome. No amount of execution turns a small market into a fund-returning company. Then team, because early-stage plans change and the ability to navigate that change is the only durable asset. Then evidence — usage, retention, revenue — as proof that the first two are not just claims.

Timing sits underneath all three and is rarely discussed openly. The same idea funded three years too early dies of market indifference and three years too late dies of competition. Investors who have seen a category before are pattern-matching on where it is in that cycle.

  • Market: can this be a billion-dollar revenue business in ten years?
  • Team: has this specific team got an unfair advantage in this specific market?
  • Traction: does the data support the story, at whatever scale exists so far?
  • Timing: why is now the moment this becomes possible?
  • Ownership: can the fund get a meaningful stake at a price that still works?

Why the process feels slow and vague

Most funds run a weekly partner meeting, and a deal has to survive several of them. The partner you are talking to is building internal conviction and needs a champion's confidence to spend political capital. That is why momentum matters so much: a round that looks like it is filling makes the internal argument easier.

Passes are usually vague because a specific reason invites debate, and firms want to preserve the relationship for a future round. 'Too early for us' most often means the evidence did not clear their bar, which is useful information stated in a form that avoids an argument.

Ownership targets shape the cheque

Most funds target a specific ownership percentage — often fifteen to twenty percent at Series A — because their return model depends on it. This is why a fund may push you to raise more than you want: a smaller round at your preferred valuation does not give them enough of the company to matter.

It also explains why some investors decline a round they like at a valuation they consider fine. If the allocation available is three percent, the outcome cannot move their fund, and the time cost of the board seat is not repaid.

Common mistakes in the pitch

Presenting a market size derived by multiplying every human on earth by a subscription price destroys credibility instantly. A bottom-up number — identifiable customers, realistic price, achievable share — is smaller and far more persuasive.

Hiding a weakness is the other reliable failure. Diligence finds it, and the discovery costs more than the weakness would have. Naming the biggest risk yourself and explaining how you plan to retire it is the single most effective move available in an early meeting.

  • Top-down market sizing with no bottom-up check.
  • Growth charts with no axis labels or no cohort view.
  • Refusing to discuss churn when churn is the obvious question.
  • Asking for an amount with no attached plan for what it buys.
  • Treating the first meeting as a close rather than a qualification.

How the game models it

In Garage to IPO, investor appetite is a function of your growth trajectory, retention, sector and the prevailing macro regime, not just your revenue. Strong months make investors more generous on valuation and less aggressive on terms; a flat quarter or a downturn tightens both.

That is why timing a raise is a skill in the game rather than a formality. Raising immediately after a breakout quarter, in a favourable market, produces terms that a mechanically identical company cannot get two quarters later.

Frequently asked questions

Why do investors care about market size so much?
Because fund returns depend on a small number of very large outcomes, and market size sets the ceiling on how large any single outcome can be.
Is profitability a negative in a venture pitch?
No, but it is not the point. Investors care whether spending capital accelerates a large outcome. Profitability matters mainly as evidence of efficiency and as leverage in negotiation.
How many investors should a founder approach?
Enough to run a real process — typically thirty to sixty qualified firms for an early round — approached in waves so feedback from the first can improve the pitch for the rest.
