How Much Should You Raise in a Seed Round?

The right amount to raise is enough to reach the milestones that make your next round easy, plus a buffer. Too little and you’re fundraising again in nine months. Too much and you give away equity you didn’t need to.

A four-step method

  1. Define the next milestone. What does a Series A investor (or profitability) need to see? Write it as numbers: revenue, growth, retention, users.
  2. Plan the work. Which hires and spending get you there? Build a simple month-by-month budget.
  3. Add time. Plan for 18 to 24 months of runway. Hitting a milestone takes longer than planned, and the next raise takes three to six months of its own.
  4. Add a buffer. 20 to 25% on top covers surprises.

The runway calculator does steps 3 and 4 for you once you know your burn.

How much equity is normal?

A common range is selling roughly 15 to 25% of the company in a seed round. Give up much more and you may find later rounds harder; much less is fine if your valuation supports it. Model your own numbers in the dilution calculator.

Signs you’re raising the wrong amount

  • Too little: your budget only works if everything goes perfectly, or you’ll need to raise again within a year.
  • Too much: you can’t explain what the extra money buys, or the valuation needed to keep dilution reasonable is far above what investors are offering.

Raising in stages

Many founders now raise in smaller pieces: a pre-seed on SAFEs, then more SAFEs as milestones hit, then a priced seed. This can raise money at rising valuations, but each SAFE adds dilution, so keep a running total with the SAFE calculator.
