SaaS investments: AI reshapes the entire category
The SaaS landscape has been fundamentally transformed by AI. In 2025, nearly every SaaS startup was also an AI startup. SaaS companies on Carta raised $9.3 billion in Q3 2025 alone, up 13% YoY and 82% versus two years prior.
The market has bifurcated. AI-native SaaS raises at premium valuations with oversubscribed rounds, while traditional SaaS faces a far more challenging environment. Median Series B valuations for AI-powered SaaS hit $175 million in Q3 2025 – a 38% YoY increase.
Total deal counts remained flat, meaning more capital concentrated in fewer companies. Average round sizes increased at every stage. Vertical AI SaaS companies for healthcare, legal, and financial services raised the largest early-stage rounds, with median Series A sizes of $22 million versus $15 million for traditional SaaS.
For the full year, SaaS VC investment reached $125 billion, up 28.8% over 2023, with SaaS maintaining its position as the largest venture category by deal count.
Leading SaaS venture capital firms
Battery Ventures, OpenView Partners, and IVP continue backing cloud software startups. Sequoia, a16z, and Lightspeed remain active across stages, with an increasingly AI-SaaS focus.
Growth investors like Tiger Global and Coatue have significantly reduced SaaS activity, pivoting to AI infrastructure. Later-stage SaaS rounds are now often led by insiders, PE firms, or corporate venture arms.
Salesforce Ventures and HubSpot Ventures make strategic investments in complementary products – providing distribution and customer access beyond just capital. According to OpenView's research, efficient SaaS companies raised 2.3x larger Series B rounds than inefficient peers in 2025.
Key trends for SaaS founders in 2026
Capital efficiency is the north star. Investors expect strong unit economics, efficient acquisition, and profitability paths. SaaS funding strategy should prioritize sustainable growth.
AI integration is table stakes. Startups without a credible AI strategy struggle to attract attention. Generative AI tools, agents, and AI automation are now expected, not differentiating.
Net revenue retention remains the most important metric (121%+ top-quartile). Investors also examine ARR growth, CAC payback, and gross margin.The exit environment improves – the $5.5B Navan IPO and $3B Nexthink acquisition in Q4 2025 demonstrate strong exits are possible.
