How much equity to give up in a seed round: investors back into your valuation, so learn their math

Sunny Ray · Mar 21, 2026 · 5 min read

Most founders give up somewhere around 15 to 20% in a seed round, and that range is the fastest way to answer the valuation question. Raise $1 million at 20% and you're at roughly $4 million pre-money, $5 million post. That's the upper bound of what you'd give away, not a target. And here's what changes how you pitch: many investors don't care about your number at all. They care about owning a fixed slice, and they back into your price from that.

You don't arrive at a valuation. You learn the math the other side is already running.

The question every investor asks

On a campaign call on March 17, a founder told me the main question he was getting from every investor was the same one: what's your valuation?

He's building in traffic tech, heading toward a certification that very few competitors are chasing. When I asked about comparables, he said there really weren't any. The competitors were happy playing in analytics, a red ocean. He wanted to be valued for the blue ocean on the other side of certification.

That's a reasonable thing to want. It's also the question that stalls more seed rounds than any other, because founders treat it as a number to defend instead of a range to understand.

No comparables? You still have math

Here's what I told him:

"Your company is worth whatever some investor is willing to pay you for at the end of the day, right?"

That sounds glib. It isn't. It means valuation isn't a property of your company, like revenue. It's the outcome of a negotiation between how much you need and how much of the company someone wants for it. You can't look it up. But you can estimate it in ten seconds.

15 to 20%: the napkin rule

The rule of thumb I gave him: "Usually people don't give away more than 15 to 20% of their business in any given round."

So the math runs backwards from the raise:

• Raising $1 million at 20% means about $5 million post-money and $4 million pre-money.
• At 15%, the same $1 million puts you closer to $6.7 million post.
• Need more than that implies? Either your story supports a higher price, or you're giving away more than a seed round should.

That's the upper bound on dilution, not the ask. As the entrepreneur, your job is to say how much you need. The valuation follows from it, and both sides know roughly how.

This also kills the worst version of the conversation, where a founder names a number with no logic behind it and an investor quietly decides they're not serious. A founder who says "we're raising a million, we expect to give up 15 to 20%" sounds like someone who's done this before.

Ownership mandates set your price

This is the part most founders don't know. A lot of funds don't start from your valuation at all. They start from a rule about themselves:

"They might have a mandate saying, hey, if we invest, we have to own 10%, 20% of your company."

If a fund needs 10% and wants to write a $1 million check, your post-money is $10 million. If it needs 20% for the same check, it's $5 million. Same company, same deck, different price, because the fund's math is about its own portfolio, not about you.

That's why I tell founders to learn the mandate before they talk price. Ask what ownership the fund typically targets and what check sizes it writes. Two answers and you know roughly where it will land, before you've said a number.

It also tells you which investors are a fit. A fund that needs 20% isn't going to lead your round at a price that only gives it 8%. You can save yourself a month by finding that out in the first call.

Pricing the future is a hard sell

Back to the founder who wanted his valuation set after certification. I understand the instinct. Once certified, the company is worth more. But investors are being asked to pay today for a risk that hasn't been retired yet. If they pay the after-certification price, they take the certification risk for free.

The way through isn't to argue. It's to structure. Raise what you need to get through certification at today's price, then raise again at the blue-ocean price once the risk is gone. Or tie part of the money to the milestone. Either way, you stop asking an investor to pay for a future you haven't reached.

What to say next time they ask

When an investor asks your valuation, give them the frame, not just a number. How much you're raising, what it gets you to, and the dilution range you're comfortable with. Then ask about their ownership target. Now you're talking about the same math.

Something like this works: "We're raising a million to get through certification. We expect that round to be in the 15 to 20% range. What ownership do you usually look for at this stage?" Three sentences, and the investor knows you understand the game.

At the same time, his investor campaigns were getting ready to widen: three new lists of about 1,000 targets each, investors, family offices and former hardware CEOs. More conversations are coming. Each one will start with the same question. Better to have the answer before it's asked.
