How a VC fund actually works

A VC is not a person with money. They manage a fund with its own investors, and that single fact explains almost everything they do.

What is it?

A VC firm raises a fund — a pool of committed money — from limited partners (LPs): pension funds, endowments, family offices, wealthy individuals.

The general partners (GPs) invest it, sit on boards, and try to return several times the fund within about ten years.

They earn a management fee (roughly 2% a year) and a share of the profits (roughly 20%, called carry). The carry is where the real money is, which is why they need enormous outcomes rather than merely good ones.

Why does a founder care?

Because it explains behaviour that otherwise looks arbitrary or unkind.

Why do they ask 'could this be a billion-dollar company?' Because a $200M fund needs to return $600M, and one company must contribute a large share of that. Why did they pass on a business that will comfortably reach $10M a year? Because that is a great business and a rounding error in their fund.

None of that is a judgement on you. It is arithmetic.

Example

A $200M fund making 30 investments over four years, average $6.6M.

The LPs expect roughly 3x — around $600M back.

Historically the distribution looks like this:

  • ~15 investments return nothing
  • ~10 return 1–2x (roughly $80M total)
  • ~4 return 3–5x (roughly $100M)
  • 1 returns 50–100x (roughly $400M)
  • That single company carries the fund. This is the power law, and it is the whole logic of the industry.

    So when a partner evaluates you, the question is not 'will this work?' but 'if this works, is it big enough to be the one?' A company with a 90% chance of being worth $30M is a worse fit for them than one with a 10% chance of being worth $2B — even though the first is a far better bet for you.

    The common mistake

    First-time founders often take a pass personally, or try to argue an investor out of their fund mathematics. You cannot. A fund that needs billion-dollar outcomes cannot fund a $50M company, however good it is.

    The second mistake: assuming a small cheque means low conviction. Funds hold reserves for follow-ons — often half the fund. A modest first cheque with reserves behind it can be worth more than a larger cheque from a fund with none.

    How it works

    Step 1: Find out the fund size

    Usually public. It tells you their cheque size and the outcome they need. A $1B fund cannot care about a $30M exit.

    Step 2: Find out where they are in the fund's life

    A fund in year one is deploying actively. In year seven it is mostly managing what it has. This affects your odds more than your deck does.

    Step 3: Ask about reserves

    'How do you think about follow-on?' is a completely normal question and tells you whether they can support you later.

    Step 4: Understand who can say yes

    Associates source, principals evaluate, partners decide. Being enthusiastically championed by someone who cannot decide is a common way to lose two months.

    Step 5: Frame honestly against the power law

    Do not oversell. Do explain what the large outcome looks like if things go right — that is the question they are actually asking.

    When to use this

    Before any VC meeting. It changes how you interpret everything they say.

    When not to use it

    This matters much less with angels, who invest their own money and can be perfectly happy with a solid outcome.
