How startup fundraising actually works

The stage you are raising, the metrics that gate it, what your round should be worth, and how long it takes. Written for founders, with 43 deep guides underneath.

Startup fundraising is the process of selling a slice of your company for the cash and time to reach the next milestone. It runs in stages, and each stage is defined by what you can prove rather than how old the company is. What changes between them is the evidence bar, the check size, and how much of the company you give up.

The seed market is roughly three times wider than the Series A market. Across the 68,731 active investors in the Round Funded database, 53,964 write checks at seed and 18,223 write checks at Series A. Investors frequently cover more than one stage, so those two groups overlap rather than divide the market, but the ratio holds: the earlier you are, the more doors there are.

Every funding stage, side by side

Ranges are 2026 norms for software startups. Your sector and geography move them.

The four questions founders actually ask

Does my startup need a Series A or a seed round first?

Almost certainly seed. The gate is revenue, not ambition: a Series A lead expects $1M to $2M ARR growing 2x to 3x a year, while a seed round is available at $10K to $50K MRR. If you are below $1M ARR you are raising a seed round, whatever you call it. Skipping seed is possible but rare, and the market is much thinner: under 20% of seed-funded companies reach a Series A at all.

What metrics do early-stage investors actually care about?

It changes by stage, and that is the whole answer. At pre-seed there is no metric bar, only evidence that someone wants the thing. At seed it is MRR and its growth rate. At Series A the bar becomes a set of four numbers a partner checks before the meeting, and failing any one of them ends the conversation regardless of the story.

MetricSeries A barWhy it is checked
ARR$1M to $2MThe entry ticket. Below it, you are raising a seed
Growth2x to 3x year over yearDirection matters more than size
Net revenue retentionAbove 100%Proves the product compounds without new logos
Gross marginAbove 70%Separates software economics from services
Burn multipleUnder 2Dollars burned per dollar of new ARR. Under 1.5 prices at a premium

How do I know if my valuation is realistic for fundraising?

Check it against your stage band first, then against 5 to 10 recent comparable rounds. At pre-seed and seed the number is mostly a market convention, not a calculation. From Series A it becomes arithmetic: B2B software prices at roughly 15x to 30x current ARR, and where you land in that range is set by growth rate and retention, not by your model. A better frame than picking a number is deciding how much you need for 18 to 24 months of milestones, then how much of the company you are willing to sell to get it.

  • Is the number inside the band for your stage in the table above?
  • Do 5 to 10 recent comparable rounds support it?
  • Does it imply selling 15% to 20% of the company this round?
  • Does the raise fund 18 to 24 months of real milestones?
  • If the answer to any of these is no, the number is the problem, not the market

How long does it actually take to close a seed round?

Three to five months from the first email to money in the bank, and that is the median rather than the bad case. The meetings themselves are a small part of it. Start the process with at least 9 months of runway, because a round that begins at 4 months of cash left is negotiated from a position everyone in the room can see.

What a raise looks like week by week

A median raise takes three to five months. Start with at least nine months of runway.

  1. Weeks 1 to 3

    Build the target list and the materials. Aim for 100 to 150 investors at pre-seed and seed, or 40 to 60 funds that actually lead at Series A. Anything broader is a mailing list, not a process.

  2. Weeks 3 to 5

    Work the warm paths first, then start cold outreach at 20 to 30 personalized emails a week. A reply rate of 10% to 15% means the targeting is right. Below 5% means the list is wrong, not the email.

  3. Weeks 5 to 11

    First meetings, batched on purpose so funds hit their decision points in the same fortnight. Sequential meetings hand every investor the option to wait and see who else moves.

  4. Weeks 9 to 13

    Partner meetings and diligence with the 8 to 12 funds that went deep. Expect roughly 1 to 3 term sheets from a process that started with 40 to 60 names.

  5. Weeks 13 to 21

    Term sheet to wire: confirmatory diligence and legals. This is 4 to 8 weeks and it is mostly waiting, so run it in parallel with getting back to work.

The numbers you need in front of you before you email anyone: burn, runway, revenue, and the model that ties them together. Getting these wrong is the most common reason a promising round stalls in diligence.

Frequently Asked Questions

What is the difference between angel investors and VCs?

An angel invests their own money, usually $10K to $100K, and decides alone. A VC invests a fund raised from other people, writes larger checks, and answers to a partnership and to the fund's own investors. That difference explains most of the behaviour you will notice: an angel can commit in one meeting, a fund cannot, and a fund needs your company to be able to return a meaningful slice of the whole fund.

How many investors should I contact?

At pre-seed and seed, build a list of 100 to 150 well-matched investors. At Series A, 40 to 60 funds that actually lead rounds at your stage. The number matters less than the match: a list of 300 investors who do not fund your stage, sector or geography converts worse than 40 who do.

Do I need a lead investor?

At seed, usually yes in practice, because most angels wait for someone to set terms and price the round. At pre-seed, often no: those rounds are assembled from small checks rather than led. At Series A, always. The lead sets the price, takes the board seat, and the round does not exist without them.

What is a SAFE and why does everyone use one?

A SAFE is an agreement to give an investor equity later, when you next price a round, in exchange for money now. It skips the valuation negotiation and most of the legal cost, which is why most pre-seed and many seed rounds close on SAFEs rather than priced equity. The trade-off is that the dilution is invisible until it converts, which is usually at your Series A.

How much runway should a round buy me?

Enough to reach the next stage's evidence bar, plus the time it takes to raise on it. In practice that means 12 to 18 months at pre-seed and 18 to 24 months from seed onward, with 3 to 6 months of that reserved for the raise itself. Rounds closing less than 12 months apart usually signal either explosive growth or a cash emergency, and investors can tell which.

Can I skip pre-seed and go straight to seed?

Yes, if you already have the evidence a seed investor prices on. The stage names describe what you can prove, not how old the company is. A team with $20K MRR and real retention is raising a seed round on day one, and a team with a deck and a plan is raising a pre-seed in year three.

What is a good reply rate on investor outreach?

Between 10% and 15% on a well-targeted list. That is the number to judge your targeting by. Below 5% the problem is almost never the email copy: it is that the people receiving it do not invest at your stage, in your sector, or in your geography.

When should I start talking to investors?

Long before you are raising. The funds most likely to lead your next round should have been getting a short quarterly update for months, so that the raise opens a conversation rather than starting one. At Series A this is explicit: the round is largely won in the 12 months before the process begins.
