The median Series A check size in 2026 is $10–12M on a pre-money valuation of $35–45M for B2B SaaS — roughly 25–30% below the 2021 peak, and that floor has now held for two years.
This is not a temporary correction. The reset from 2022–2023 has calcified into a new normal — and as of mid-2026, the 2025 figures remain the latest full-year dataset and the right benchmark to plan against. Founders who are still anchoring their expectations to 2021 comps are setting themselves up for a painful process. The good news: the floor is real, the bar is clear, and the investors who are still writing checks are doing so with conviction.
Median Series A Funding Amount in 2026: The Data
Based on Carta, PitchBook, and AngelList data from 2024–2025, here is where the market has settled across check size, valuation, and dilution by company type.
| Company Type | Median Check | Pre-Money (Median) | Dilution | ARR Required |
|---|---|---|---|---|
| B2B SaaS | $10–12M | $35–45M | 20–22% | $1.5–3M ARR |
| AI-Native SaaS | $15–20M | $80–120M | 15–18% | $1–2M ARR |
| Dev Tools / Infra | $12–18M | $40–70M | 18–22% | $500K–$1.5M ARR |
| Fintech / Regulated | $12–15M | $40–55M | 20–25% | $2–5M ARR |
| Consumer / PLG | $8–12M | $25–40M | 22–28% | Strong growth + retention |

What Changed: 2021 Peak vs 2025 Median

How Much Should You Actually Raise?
The most common mistake I see founders make is starting with "how much can I raise?" instead of "how much do I need?" These are different questions with different answers. The amount you raise is not a status signal — it is a constraint you will live under for 18–24 months.
The correct framework: identify your Series B milestone (typically $5–8M ARR with 2x+ growth and a repeatable sales motion), model your monthly burn rate to get there in 18–24 months, then add a 25–30% buffer for the unexpected. That math lands most SaaS companies at $10–18M.
Too little (<$8M)
Awkward runway. You are back fundraising in 12 months, which is never a position of strength.
Right-sized ($10–18M)
18–24 months of runway to hit Series B milestones. Enough to hire the team and invest in GTM.
Too much (>$22M pre-traction)
Signals desperation or valuation mispricing. Creates unrealistic Series B expectations.
The AI Premium Is Real — But So Is the Scrutiny
AI-native companies are raising Series A at 2–3x the pre-money valuation of comparable traditional SaaS companies. A B2B SaaS company doing $2M ARR at 120% YoY growth might get $40–50M pre-money in 2026. The same revenue trajectory for an AI-native product — particularly one with workflow ownership and demonstrable retention — gets $90–130M pre-money. In multiple terms: AI-native vertical SaaS is pricing at roughly 12–18x ARR at Series A, versus 8–12x for traditional horizontal SaaS — back to pre-2021 norms — and 5–8x revenue for marketplace and consumer businesses, where unit economics get scrutinized hardest.
But the window is narrowing. Investors who overpaid for AI hype in 2023–2024 have now seen enough churning pilots and weak NRR to tighten the criteria. The questions at Series A for AI companies in 2026 are no longer just about ARR — they are about whether the product is embedded in workflows or just used occasionally.
Net revenue retention >110%
Top of range — commands 3x non-AI premium
NRR 90–110%
Market premium — 1.5–2x non-AI valuation
NRR <90% with churning pilots
No premium — gets priced like traditional SaaS
No enterprise paying customers
Most Series A investors pass regardless of AI angle
How the Dilution Math Works at Series A
Most founders underestimate how much dilution happens at Series A because they forget the option pool expansion that typically occurs pre-close. A standard Series A deal looks like this in practice — and founders who do not model this before negotiating leave real equity on the table. The stakes compound over time: a $5M difference in pre-money valuation at Series A can be worth $15–40M at exit depending on subsequent rounds and exit multiples. Negotiate it — but do not lose a great lead investor over $5M in pre-money when the right partner accelerates your path to a much larger outcome.
| Scenario | Pre-Money | Check | New Dilution | Option Pool Add | Total Dilution |
|---|---|---|---|---|---|
| Typical (no AI) | $42M | $12M | 22.2% | 5% | ~25–27% |
| Top quartile (no AI) | $65M | $18M | 21.7% | 5% | ~25% |
| AI-native median | $95M | $18M | 16.1% | 4% | ~19–20% |
| AI top quartile | $150M | $25M | 14.3% | 4% | ~17–18% |
Option pool expansions pre-close are standard — negotiate the size before you agree to the pre-money valuation. A 10% option pool addition on a $42M pre-money costs founders an extra 4–5% dilution that is not visible in the headline number.

How to Navigate the 2025 Series A Market
The best thing a founder can do in this market is stop anchoring to 2021 comps and start building to the actual bar. Here is what I tell founders who are 6–12 months from Series A:
- →Get to $2M ARR with >120% NRR before pitching. This is not a hard floor but it removes most of the objections before you walk in the door. Below $1.5M ARR, you are fighting an uphill battle unless your growth metrics are extraordinary.
- →Run a competitive process with 6–8 qualified firms simultaneously. Solo-path processes almost always get lower valuations. The FOMO dynamic compresses timelines and anchors valuation at the high end.
- →Model the dilution with the option pool before you sign. Negotiate the option pool size as part of the pre-money conversation — not after. A 10% pool on a $42M pre-money costs you 4% dilution on top of the headline number.
- →Track your public comps. Series A valuations are loosely pegged to public SaaS multiples — when those contract, private rounds compress too. Check the SaaS Valuations Dashboard monthly to calibrate expectations in real time.
The median Series A in 2026 is not bad news. It is a return to sanity.
A $42M pre-money on $2M ARR growing 150% YoY is a fair deal. The founders who get it done are the ones who built to the bar instead of hoping the bar would come down.
