What Series A actually requires in 2026
The bar moved. Capital efficiency now sits alongside growth rather than behind it, and a company growing quickly on a 3x burn multiple is a harder round than one growing a little slower on 1.5x.
Seven metrics carry most of the decision:
- ARR — $1–2M is where most rounds price. Below $800K it tends to be a seed extension.
- Growth — roughly 3x year-over-year.
- Net revenue retention — above 100%, so existing customers grow on their own.
- CAC payback — inside 12 months.
- Burn multiple — under 2x.
- Customer count — enough logos that no single one dominates revenue.
- Runway — 9 months or more, so you are not negotiating against a clock.
One number does the work
Rounds are rarely won on a balanced scorecard. They are won on one metric that is genuinely exceptional and no metric that is disqualifying. This tool identifies the disqualifying ones first, because those are what a partner meeting will find.
Questions
Is $1M ARR a hard requirement?
No, but it is the centre of gravity. Companies raise Series A rounds below it on the strength of growth rate, team, or a category thesis — those are exceptions and they are priced as such.
What if my NRR is under 100%?
It means existing customers shrink and new sales refill the bucket rather than grow it. Investors treat this as the strongest single signal about product value, so it is worth fixing before a raise rather than explaining during one.
How much does runway really matter?
More than most founders expect. Under eight months, the other side knows you have to close, and terms reflect it. Starting a raise with twelve months is a materially different negotiation.
Does this replace talking to investors?
No. It tells you which conversation you are about to have. If a metric is below the bar here, expect that to be the question you get asked in every first meeting.
