B2B SaaS Funding This Quarter: 2026 Benchmarks and Deal Data

B2B SaaS funding this quarter is best read from the most recently closed quarter. Carta recorded $30.4 billion in startup funding in Q1 2026, with 83% of SaaS capital going to AI startups and the down-round rate at 11.4%. The stage benchmarks below are distributions, not gates.

As of August 2026, the freshest complete data on this page covers Q1 2026. Carta, PitchBook and SVB publish on quarterly or half-yearly cadences, so any page on b2b saas funding this quarter reports the last closed quarter, not the one you are raising in. Every figure below carries the period it measures.

SaaS is no longer one funding market. The AI share of SaaS capital is the most important row in the table below: it means the sector benchmark and the benchmark that applies to you are probably different numbers. Pricing a round off 2021 SaaS comparables now gets it wrong in both directions.

SaaS VC funding 2026: the scoreboard, with the period on every number

Every headline number measures a different thing over a different window, so here they sit side by side.

Capital grew faster than deal count. SaaS startups on Carta raised $28.2 billion in the first three quarters of 2025, up 25% year over year, across 1,315 funding events, an annual pace of 1,753 rounds (Carta). More money moving through a broadly stable number of rounds lifts the average round size, not your odds of getting funded.

The friendliest number here is the down-round rate, which fell to 11.4% in Q1 2026. If you have been sitting on a 2021 price and delaying a raise to avoid a markdown, that risk has eased.

What SaaS seed rounds and Series A rounds require on revenue

There is no ARR gate, but there is a distribution, and you should know which end of it you are pitching from. The four figures below come from SVB's State of the Markets, measured at the time of the raise, and SVB is explicit that some companies raise a Series A with no revenue while others raise with tens of millions.

• Seed: median annual revenue of $363,000 in 2025, against $156,000 in 2021.
• Series A: median $3.3 million in 2025 against $1.6 million in 2021, with the middle 50% between $1 million and $6.5 million.
• Series B: median $7.1 million in 2025 against $5.8 million in 2021.
• The jump between them: companies typically grew revenue 8x to 12x from seed to Series A.

Being under the median is a positioning problem, not a disqualification. Read every row as a distribution and write the paragraph that explains where you sit in it before an investor has to ask.

The bar moved in one direction: more revenue, slower growth. Seed companies raising in 2025 grew 322% year over year against 959% in 2021, from a median revenue base of $363,000 versus $156,000 (SVB). A seed narrative built on growth rate alone is pitched at the 2021 market.

B2B SaaS valuations and SaaS ARR multiples are three different numbers

The multiple in the headline almost never applies to your round.

Do not quote a public comp to a seed investor. Public medians price liquid, mature companies on trailing revenue; private seed and Series A rounds are priced on stage medians and ownership targets, and the two move on different clocks. Carta's Q3 2025 SaaS medians were up sharply year over year, while its Q1 2026 read describes early-stage SaaS valuations softening even as headline funding recovered (Carta).

For stage-level pricing, see the SaaS startup valuation benchmarks for 2026 and the Series A valuation benchmarks.

The AI premium is the main variable in enterprise software funding

Whether investors code you as an AI company now moves your price more than your category does.

• The premium compounds with stage: 38% median at Series A in 2025, rising to 193% at Series E and later (Carta).
• Public markets split the same way: AI infrastructure and cybersecurity names can still command double-digit revenue multiples while the broader enterprise SaaS index has repriced lower (PitchBook).
• The pricing model is shifting underneath you: PitchBook argues AI is pushing software from seat-based to outcome-based pricing, with agentic systems competing against labour budgets rather than software budgets (PitchBook).

Do not take the highest seed price on offer. Carta's read on SF and NYC seed pricing is that high seed valuations raise the performance bar for the next round and can make Series B materially harder to raise (Carta). The step-up you sign at seed is the revenue you owe at Series B.

What to do with this before your next raise

Turn the benchmarks into three decisions: what you claim, who you pitch, and when.

1. Anchor on your stage median, then explain the gap. Name your revenue number before anyone asks, with the growth rate and burn behind it in the same breath.
2. Say what kind of AI company you are, precisely. Vague AI framing reads as positioning and gets discounted. Value delivered against a labour budget is a stronger claim than a model in your stack.
3. Price for the round after this one. Work backwards from the revenue step-up your next stage implies, then ask whether you can grow into the valuation on offer.

Market data tells you what is normal. It does not tell you which funds are actually deploying into your stage and sector this quarter. Causo matches you to the investors most likely to fund you and drafts the outreach, and if you sell developer or infrastructure software, the active seed dev tools VCs list is the concrete next step.

FAQ

How much ARR do you need to raise a Series A for a SaaS startup? There is no fixed threshold. SVB's State of the Markets put the median annual revenue at the time of a 2025 Series A at $3.3 million, with the middle 50% of companies between $1 million and $6.5 million. SVB is explicit that some companies raise a Series A with no revenue while others raise with tens of millions, so read the range as a distribution rather than a gate.

What revenue multiples are SaaS startups getting in 2026? The most quoted figure is a public-market one. PitchBook put the median public enterprise SaaS enterprise value to trailing-12-month revenue at 3.3x as of 31 March 2026, against 4.9x at year-end 2025 and 6.2x at year-end 2024. Private rounds are priced on stage valuation medians, not on that public multiple.

Is SaaS venture funding recovering in 2026? In aggregate yes, and unevenly. Carta recorded $30.4 billion of startup funding in Q1 2026 with more than 60% of it going to AI companies, and reported that early-stage SaaS valuations softened over the same period. Carta's 2025 SaaS data shows the extra capital raised average round sizes more than it raised the number of funded companies.

How has AI affected SaaS startup valuations? It split the market in two. Carta measured a 38% median valuation premium for AI startups over non-AI startups at Series A in 2025, widening to 193% at Series E and later. PitchBook separately argues AI is moving software pricing from per-seat to outcome-based, which changes the revenue quality investors underwrite.

How much revenue do you need to raise a Series B? SVB put the median annual revenue at the time of a 2025 Series B raise at $7.1 million, against $5.8 million in 2021. The bar rose less at Series B than it did at seed and Series A over the same period. Carta separately warns that unusually high seed pricing raises the performance required at the next round.
