How much should you raise in a seed round? Size the ask to your evidence
A typical seed round in 2026 is a few million dollars. PitchBook-NVCA data compiled by Waveup puts the US median seed deal at $3.0M in the first half of 2026, flat since 2024, and Carta data shows a median priced software seed of $4.1M raised at a $24.3M post-money valuation, about 18% dilution. But the right amount for you is not the median. It is the amount your evidence can justify and that gets you to the next proof point.
Raise more than your evidence supports and the round stalls. Raise what it supports, prove the next thing, and come back stronger. I watched a founder learn this on August 24.
The medians, and why they mislead
Here are the numbers, as compiled by Waveup:
- US seed median deal size: $3.0M in H1 2026, flat since 2024 (PitchBook-NVCA).
- Priced software seed, six months to July 2026: median $4.1M raised at $24.3M post-money, 18% dilution (Carta).
Medians are useful for a sense of scale. They are dangerous as targets. The companies that make up the median mostly had traction that justified their round. If you take the median ask without the median evidence, investors notice the gap before they notice anything else.
Match the ask to the evidence
On August 24 we were on a call with a founder who had been running his company for about ten years. He was asking for $6M. His monthly recurring revenue growth was flat, and his investor campaign had produced exactly one reply.
That reply count was the signal. Mailbox health was fine. The ask was the problem. A $6M ask next to flat growth and a modest revenue figure read as a mismatch, and investors were quietly saying no by not answering.
The advice from the team, which he took: drop the ask to a $250K growth round aimed at angels and high-net-worth individuals. Use it to prove the new distribution model can grow MRR over three to four months. Then come back for a proper seed with the growth curve to back it.
Emiliano, my teammate, put the bigger point plainly on that call: traction is now table stakes. Even an MVP is no longer enough.
The bridge or growth round option
A smaller round before a real seed is not a failure. It is a way to buy evidence.
- It is easier to fill. A $250K round needs a handful of angels, not a lead fund.
- It preserves your VC relationships. You do not burn seed investors on a round that is not ready. On that call we deliberately kept the VC outreach separate so those relationships would be intact for the later seed.
- It creates momentum. Emiliano's point was that a smaller round that fills fast creates its own urgency as it closes.
- It changes the story. "We raised $250K and grew MRR for four months" is a better seed pitch than "we have been raising for six months".
Who writes which check size
The ask determines who you should talk to. That founder's $250K target was incompatible with the seed and Series A funds he had been emailing, who write checks of $1M and up. It fits angels, high-net-worth individuals and strategic partners.
A rough guide to matching:
- Small growth or pre-seed rounds: angels, operators, high-net-worth individuals, strategic partners.
- Seed rounds of a few million: seed funds, with angels filling the rest.
- Larger seed rounds: a lead fund that sets the terms, plus followers.
Pitching a $1M-minimum fund for a $250K round wastes both sides' time. Pitching an angel for $5M does too.
Dilution math in plain numbers
At the Carta median, a $4.1M raise at $24.3M post-money is about 17% to 18% of the company. Simple rule: amount raised divided by post-money valuation is the share you sell.
Founder ownership compounds down with every round. Waveup's compilation of Carta data shows founders own about 56% after seed across 2021 to 2025 rounds. Every extra dollar you raise before you need it costs ownership you will not get back. That is another reason to raise what the evidence supports, prove more, and raise again at a better price.
What I tell founders before they set the number
Write down three things before you pick an amount. The milestone the next round will want to see. What it costs to get there, honestly, including the hires you will make. And the evidence you have today that makes an investor believe you will hit it.
If the third list is short, the first number should be small. That is not pessimism. It is the fastest route to a large round, because the small one fills, the evidence arrives, and the next conversation starts from strength.
The founder on the August 24 call went through exactly this. He agreed to drop from $6M to $250K on the call, because the smaller round was the one his evidence could close, and because it kept the bigger round possible later. Going from a $6M ask to a $250K one is a big step for any founder to take on a single call, and it was the right one.
How long should a seed round last?
Long enough to hit the milestones that make the next round easy, with a buffer for things going slower than planned. Work out what the next round needs to see, estimate how long it takes to get there, and add margin. Then size the round to that, not to a number of months someone told you was standard.
When to come back for the real seed
Come back when you can show the thing that was missing. For the founder on that call, that meant three to four months of MRR growth from the new distribution model. For you it might be a set of paying customers, a retention curve, or a channel that brings in buyers at a known cost.
Signs you are ready:
- Your investor outreach gets real replies, not silence.
- You can show a trend, not a single data point.
- The ask matches the median evidence for that round size, not just the median ask.
- You have been talking to the right seed investors for months already, without asking for anything.
Signs your ask is wrong
You can usually tell from the market's response before anyone tells you directly.
- Silence. Plenty of sends, few or no replies, healthy mailboxes. The ask or the story is off, not the delivery.
- Polite deferrals. "Come back when you have more traction." That is an investor telling you the evidence does not match the round.
- Questions about smaller amounts. If several investors ask whether you would take less, listen.
- Interest from the wrong investors. If only funds far below your round size engage, the market is pricing your round for you.
Any of these is a reason to revisit the size before you burn more of your list.
Meet investors before you need them
The best time to start a seed conversation is during the growth round. Invite the seed investors you want onto your show. Interview them about what they look for. When you come back with the growth curve, you are not a stranger with a deck. You are someone they already know, showing them the thing they told you they wanted to see.

Frequently asked questions
What is the average seed round size in 2026?
PitchBook-NVCA data compiled by Waveup puts the US median seed deal at $3.0M in H1 2026. Carta data shows a median priced software seed of $4.1M at a $24.3M post-money valuation.
How much equity do founders give up in a seed round?
At the Carta median it is about 18%. Divide the amount raised by the post-money valuation to get the share sold.
Can I raise a smaller round before my seed?
Yes. A small growth round from angels and high-net-worth individuals can fund the proof you need, and keeps seed investor relationships intact for later.
How long should a seed round last?
Long enough to hit the milestones the next round needs, plus a buffer. Size the round to those milestones rather than to a standard number of months.
