44+ Series B AI Startups — $7B Raised at $90M Median

Series B AI companies in 2025-2026 are the scaling engines of the AI revolution. Our dataset tracks 37 Series B AI companies that raised a combined $7.0B at a $90M median — the highest median of any stage-industry cross-section. These companies have moved beyond product-market fit and are aggressively expanding their enterprise customer base. The $7.0B total underscores how much capital is flowing into proven AI companies: it exceeds the entire funding total of verticals like Cybersecurity ($2.8B) and Climate ($1.5B). Series B AI companies typically have $10-30M in ARR and are growing 100-200% year-over-year. Investors at this stage — including Tiger Global, Coatue, and IVP — are focused on market leadership potential and efficient unit economics. For GTM teams, 37 companies with $7.0B in fresh capital represent the highest-value segment in the dataset. These are enterprise-grade prospects with substantial budgets and professional procurement processes. They are buying infrastructure, security, sales tools, and business intelligence platforms.
