The median Series A check size in 2025 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 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 2025: 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
The 2021 Series A market was an anomaly driven by zero-interest-rate capital seeking yield in private markets. The correction was inevitable. Here is the delta.

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 2025. The same revenue trajectory for an AI-native product — particularly one with workflow ownership and demonstrable retention — gets $90–130M pre-money.
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 2025 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.
| 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 2025 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.
