I sat across from a founder a couple of months ago who had no revenue, no signed pilots, and a five-year forecast that bent in three different directions depending on which page you were reading. He'd been told he needed it. He apologized for it before I'd even asked a question. Which was, in its own way, the most useful information I got that hour. How to evaluate startups with no revenue tends to get framed as a numbers problem, but the actual work is reading the founder, the category, and the prototype well enough that the absence of numbers stops mattering.
The deck doesn't tell you what you need to know.
Why these aren't lucky exceptions
Folklore exists for a reason. Sara Blakely funded Spanx with a hand-cut prototype, no retail orders, and a category that didn't yet have a name. Multiple investors passed on Airbnb because three air mattresses on a floor wouldn't model, and the deck, by every traditional standard, was unfundable. Dropbox raised on a product that didn't exist; Drew Houston shot a short video of how it would feel to use the thing, posted it, and watched the waitlist do the talking. These keep getting filed as exceptions. They aren't, really. They share a pattern that doesn't show up in a spreadsheet, a founder who could see the problem at a level of texture nobody else had reached, a category bending in a direction the existing players couldn't follow, and a product idea grounded in some small, specific decision that gave the whole thing weight.
What you're actually reading at the pre-revenue stage
What you're actually reading, when there's nothing to measure, is texture. Does the founder talk about the problem the way someone who has lived inside it talks, or the way someone who read a Substack about it talks? There is a difference and it shows up within the first ten minutes. Is the category settling into its current shape, or is it quietly drifting into something that won't have the same gatekeepers in three years? Is the product idea built around a tagline, or around a particular, almost stubborn, choice that suggests the founder knows which detail the existing players have been ignoring? None of this is on the P&L. All of it predicts whether you're going to be having the next conversation in five years or quietly forgetting this one.
The case against the projection
The most experienced pre-revenue investors I know quietly stopped asking for financial projections years ago. Not because numbers stopped mattering, they matter enormously once they exist. But a five-year model built on zero operating history is a creative writing exercise wearing the clothes of math. It is the founder's hope, formatted as a spreadsheet, and the investor's job is to assess the hope itself, not the formatting around it. What replaces the projection, at least in the rooms where pre-revenue checks actually get written, is something closer to conviction discipline. Writing down precisely what would need to be true for this thing to work. Then pressure-testing each assumption against the founder, the market, and the prototype, line by line. It is not faith. It is the deliberate exchange of false precision for honest uncertainty, which is harder than most decks are willing to admit.
What pre-revenue founders should be showing instead
For founders, the implication cuts both directions. If your pitch is propped up on a forecast you can't defend, you're competing on the wrong dimension and the wrong investor will be the one who likes the deck. The investors capable of writing a check before revenue are not looking for a polished projection. What they are looking for, and almost no first-time founder realizes this, is evidence that you've already designed the company to be governable when revenue does arrive. OKRs that ladder somewhere. A board that already meets like a board. Financial discipline that doesn't depend on a CFO showing up. A decision rhythm that won't snap the first time growth becomes real. Conviction is what earns the check. The rest of the work is what keeps that check from being the last one anybody writes you.
So the question of how to evaluate startups with no revenue ends up being a question about people, mostly. Which founders can carry a thesis without a number to prove it. Which investors can read that without retreating into a model. The companies that defined the last two decades were almost all backed before there was anything to measure. The ones that will define the next two probably will be too. Some of the people writing those checks are very good at this and most are not. The market sorts them out eventually.
Which part of your conviction is currently being outsourced to a spreadsheet, and what would actually change if you had to defend it tomorrow without the spreadsheet open?
