founders raise for 18 months. the market in 2026 takes about 23 months to hand over the next check. that five-month gap is where good companies die waiting.
almost nobody plans for it. on the day the wire clears, the founder feels rich, the team feels relieved, and the next-round timeline gets penciled in for "q3 next year, maybe q4." every assumption in that sentence is from a different decade.
the planning template hasn't moved. the market has.
where the 696-day number comes from
Carta's 2026 reports put the median time between rounds at roughly 696 days — about 23 months. it's been climbing every year since 2021. in 2021 the median was around 14 months. that number doubled, and most founders are still building cash plans against the old version.
the average hides the spread. the top-tier ai companies are raising every 6-9 months at multiples nobody else can touch. 80% of every venture dollar in early 2026 went to 29 companies. for the median founder, the gap is longer than 23 months, not shorter.
set the seed runway against the new median and the shape of the problem becomes a single line on a single screen.
the math that breaks
a normal seed-to-series-a plan looks like this:
- raise seed in month 0
- runway: 18 months
- start raising series a at month 14
- close by month 18, before cash runs out
every assumption in that timeline made sense in 2021. it's all broken now. redo it with 2026 numbers: 18 months of runway, 23 months between rounds, five months of cash that doesn't exist.
founders solve this gap, when they solve it at all, by:
- raising more at the seed — lower valuation, more dilution, but more time
- starting the next raise much earlier — month 9 instead of month 14
- getting to default-alive before the cash runs out
- taking a bridge round, often at the same cap
option 4 is the most common because it requires the least planning. it's also the most expensive in dilution, because bridges aren't free even when they're "friendly."
what changed since 2021
three things compounded.
the active investor pool shrank. crunchbase data puts the number of investors who wrote any check in 2025 around 10,000 — the lowest since 2020 — even as total venture dollars hit records. fewer hands, larger checks, longer diligence.
check sizes barbelled. small "let-me-prove-it" checks went away. either you're getting a $50k friends-and-family or a $5M+ priced round. the middle dried up.
the bar for series a got higher. in 2021 a seed-to-series-a was 12-18 months at $500k–$1M arr. in 2026 the series a hurdle is closer to $2M arr with 100%+ nrr. that takes longer to reach. the gap isn't just market timing — it's that you need more revenue to clear the new bar.
what to do about it
three things, in order.
raise for 24 months, not 18. if you're targeting an 18-month runway, you're planning for the round that closed in 2021. ask for 24 months of runway in your raise, or be ready to give up more dilution in a year. neither is great. ignoring it is worse.
start the next raise at month 9. not month 14. the goal isn't to close in three months. the goal is to have six months of conversation before the cash situation gets uncomfortable. urgency kills price. if you're raising under pressure, the investor knows.
operate to default-alive as the backup plan. default-alive means if we don't raise, we still survive. the founders who got through 2023–2024 all said some version of "i thought we'd raise, then we didn't, so we cut to default-alive in q3, then we raised six months later anyway." default-alive isn't surrender. it's the option that keeps the company alive long enough for the round to close.
18 months of runway against a 23-month round means five months of cash that doesn't exist — and the gap is widening, not closing.
how zift handles this
founders don't ignore the five-month gap on purpose. they ignore it because the numbers required to plan around it — accurate burn trend, runway by scenario, default-alive cost structure — are usually trapped in a google sheet that hasn't been touched since the last board meeting.
zift keeps that picture live. burn this week versus last week, runway under three scenarios (base, flat growth, decline), the dollar figure for default-alive at current revenue. on monday morning, in your inbox, in three minutes.
if you're a finance lead at a series a team doing this across multiple entities or currencies, zift handles that too.
696 days is a structural change in the market, not a story. the founders who survive it didn't get lucky — they planned for the gap to be longer than the template said.
