The Investor's Logic: The Power Law

A $40 million seed fund will write roughly 30 first checks over four years, hold back close to half its capital for follow-ons, and tell its LPs it intends to return three times the fund. Call it $120 million coming back.

Look at where that $120 million comes from and the whole business changes shape.

Around half those 30 companies return nothing. Not a reduced amount. Zero. Another third return somewhere between the original check and two or three times it, which feels like a decent outcome and moves the fund almost not at all. So the $120 million has to come from one company. Two, if the partners are lucky. This is the power law, and it is the most useful thing a first-time founder can understand about the person sitting across from them.

A bank lending to 30 small businesses needs close to all 30 to pay back. One default is a bad quarter. Five is a crisis. Every question the lender asks is a version of the same question: how likely are you to survive?

A venture fund holds 30 companies and expects most of them to die. The partners have already priced that in. They budgeted for it before they met you.

Which means the question they're actually asking has almost nothing to do with your survival odds.

Most first-time founders pitch as though they're applying for a loan. The deck is built to prove safety. Conservative projections, a careful market estimate, a slide on why the risks are manageable. It is a well-made argument for a question nobody in the room is asking. A partner reading that deck is running a different calculation entirely: if everything goes right, how big can this get?

You can be a company with a 90% chance of building a solid $20 million business and get passed on by every seed fund you meet. Meanwhile, a company with a 5% chance of becoming a $2 billion business gets funded in a week. Neither outcome is a judgment on quality. Both fall directly out of the arithmetic above.

Here's the calculation a partner runs, usually in the first few minutes, often without noticing they're running it.

A seed fund buys somewhere between 10% and 20% of a company at entry. By the time that company exits, after a Series A, B, and C have each diluted the cap table, the fund might hold 6% to 10%. Take the friendlier end and call it 8%.

For that $40 million fund, 8% of an exit needs to be worth $40 million just to return the fund one time. That's a $500 million exit. To deliver the 3x the partners promised, from one company, you're looking at an exit north of $1.5 billion.

So when a partner reads your deck, one of the questions underneath is simple: is there a version of this where the company is worth over a billion dollars? If the honest answer is no, they can like you, believe you, and still be unable to invest. Their fund model does not have a slot for a company that works out well.

This is also why the same company gets funded by one firm and passed on by another with an identical thesis. A $40 million fund can get very interested in a business heading toward a $500 million outcome. A $1 billion fund cannot. That same exit is a rounding error against their model. Nothing about your company changed between the two meetings. The denominator did.

Go back through the rejections you've collected and read them again with this in mind.

"It's a bit early for us." Sometimes true. Often it means the partner couldn't construct a path to a fund-returning outcome and reached for the kindest available exit.

"We love the team, we're going to pass." Both halves are usually sincere. The team was real. The magnitude wasn't there.

"Not quite a fit for our thesis." Frequently a statement about size and shape rather than sector.

None of this means your business is bad. Plenty of excellent companies are poor venture investments, and the founders of those companies spend months absorbing rejections as verdicts on their work when they were really verdicts on fit. That misreading is expensive. It sends founders back to rebuild a deck that was fine, chasing an objection that was never about the deck.

Take twenty minutes and do this before your next meeting.

Start with your realistic best case. Not your dream, and not your conservative plan. The outcome where the market breaks your way, execution holds, and you're proud of what you built in year eight. Put a revenue number on it.

Apply a defensible multiple for your category. Software businesses have traded anywhere from 4x to 15x revenue depending on growth and the year, so pick something you could argue for in a room. That gives you a rough exit value.

Now multiply by 8%. That's roughly what a seed lead walks away with.

Compare that number to fund sizes. If your math produces $30 million for the investor, funds in the $30 million to $50 million range can build a real position around you. Funds at $300 million cannot, and no amount of deck polish changes it.

This one calculation will do more for your target list than another week of research. It tells you which end of the market to spend your time on, and it tells you when to stop taking a certain kind of pass personally.

It also changes how you present. Once you know a partner is underwriting magnitude, the slide that matters most stops being the one about risk mitigation and becomes the one that makes the ceiling credible. Not louder. Credible. Show why the market can actually be that large, why you can reach it, and why this is the moment it opens up.

The power law is why investors chase outliers and why so much fundraising advice tells founders to think bigger. That advice is usually delivered without the arithmetic, which makes it sound like a personality trait. It isn't. It's a structural fact about a fund's obligation to its LPs, and it explains more investor behaviour than any other single idea.

Understanding it won't get you funded. It will stop you from spending six weeks pitching the wrong twenty firms.

Next in this series: The Ownership Equation. Check size divided by ownership target sets the highest valuation a fund can accept. Three numbers, and they lock before anyone opens your deck.

Running the fund-returner math by hand takes twenty minutes per firm. Doing it across a list of eighty is the part founders skip, which is why so many raises are aimed at funds that were never able to say yes.

CherryPitch reads what your deck signals about stage, scope and ambition, then matches you to investors whose fund size and thesis can actually accommodate that outcome. Every match comes with the reasoning attached, so you can see why a firm fits before you spend a meeting finding out.

We also publish what we learn. Our quarterly research covers what pre-seed decks signal to investors and what actually gets founders meetings, drawn from the decks and outreach running through the platform.

Eight decision models funds run on, one per post.

What is the power law in venture capital?

It describes how returns distribute across a venture portfolio. Most investments return nothing or close to it, and one or two produce nearly all the fund's gains. Funds build their entire selection process around finding those one or two.

Why do investors pass on companies that are clearly going to work?

Because working and returning a fund are different bars. A business heading toward a $20 million outcome can be excellent and still sit outside what a venture fund's model can use. The pass is about magnitude, and it usually has nothing to do with the quality of what you showed them.

How do I know whether my company can return a fund?

Take your realistic best-case revenue in year eight, apply a defensible multiple for your category, and multiply the result by 8%, which approximates what a seed lead holds after later rounds dilute them. Compare that number to the fund sizes you're pitching.

Does the power law apply at pre-seed?

Yes, and often more sharply. Pre-seed funds are smaller, so the exit needed to return them is lower, which widens the range of companies that can work for them. That is exactly why fund size should shape your target list before thesis does.

Where does this leave warm introductions?

An introduction gets your deck opened faster. It does not change the arithmetic underneath the decision, so a warm intro to a fund that can't use your outcome still ends in a pass.
