How Startup Valuations Actually Work

The first time I sat down with a VC to talk about a raise, I assumed there was some formula behind the valuation number. Some model that spit out what the company was worth. There wasn't. The number on a term sheet is a lot less scientific than most people think, and figuring out how it actually gets set was one of the more useful things I learned raising money.

Pre-Money and Post-Money

The first thing that tripped me up was the difference between pre-money and post-money valuation. It sounds simple, but the distinction changes everything at the negotiating table.

Say you're raising $5 million. The pre-money valuation is what the company is worth before the money comes in. The post-money is what it's worth after.

If the pre-money is $20 million and the investor puts in $5 million, the post-money is $25 million. That investor now owns $5M / $25M = 20%.

Where this gets tricky is when someone says "we raised $5 million at a $100 million valuation." Was that pre-money or post-money? If it's pre-money, the investor owns about 4.8%. If it's post-money, they own 5%. That gap might sound small, but when you're negotiating control of your company, every percentage point matters.

Why DCF Doesn't Work Here

I used to assume VCs had some discounted cash flow model running in the background. Project future earnings, discount them back to present value, and that tells you what the company is worth. That's how you'd value a mature business with predictable revenue.

For an early-stage startup, it falls apart completely. There are no reliable cash flows to project. The business model might pivot three times before generating meaningful revenue. Any assumptions you plug in are so speculative that the output is meaningless.

I've built pitch decks with five-year revenue projections. Everyone building them knows the numbers are aspirational at best. The VCs across the table know it too. DCF pretends those guesses are precision inputs. Nobody takes it seriously at the early stage.

What Actually Drives the Number

So if it's not financial modeling, what is it? After enough fundraising conversations, I started to see the patterns.

The biggest anchor is comparable companies. If a startup similar to yours at a similar stage just raised at a $30 million pre-money, that becomes the reference point. Investors adjust up or down based on your market, your team, and your traction relative to that comparable. It's more art than science, but it's grounded in something real.

Then there's ownership math. Most VCs want to own 15-25% of a company in their entry round. If a fund wants 20% and they're writing a $4 million check, the valuation is just arithmetic. $4 million for 20% means a $16 million pre-money. The "valuation" is really an output of the check size and the target ownership, not some independent assessment of what you've built.

And then there's narrative and timing. A strong story about a large market can push valuations well past what any model would suggest. In 2021, narrative was enough. Investors were competing for deals, and fear of missing out pushed numbers to levels disconnected from fundamentals. That correction is playing out now, and it's not pretty.

The VC Math

The piece that finally made the whole system click for me was understanding how VC fund economics work. They're not looking for a modest return. Their model requires that winners return 10x or more.

If a VC invests $5 million for 20% of your company, they need that stake to be worth at least $50 million at exit. That means your company needs to reach a $250 million exit or higher.

Once I understood this, a lot of conversations that had confused me started making sense. When an investor passes despite saying they love the company, it's often not about the company. It's that the math doesn't work for their fund at the valuation you're asking for.

This also explains something that frustrated me early on. A company on track for a $40 million exit is a great outcome for founders. But for a VC who invested at a $25 million valuation, that's barely a return. Their portfolio needs the big swings.

What the Number Actually Means

A valuation is a negotiated price between someone who needs capital and someone who needs ownership. It reflects competing term sheets, market timing, the strength of your story, and how badly each side wants the deal.

It's not what the company is "worth" in any fundamental sense. Once that clicked for me, a lot of the fundraising game started making more sense.
