The 11 Oxford-based AI startups shown here span rounds from a $100K Series A for Ribbit.ai in March 2022 to a $140M Series C for autonomous-vehicle company Oxbotica in January 2023 — the largest disclosed figure in the dataset. A pronounced healthcare AI cluster has attracted recurring capital: Brainomix closed an $18M Series C in March 2025, Optellum raised $14M at Series A in September 2022, and Ultromics drew $33M at Series B in August 2021. Drug-discovery company Exscientia and code-automation firm Diffblue both recorded Series Unknown rounds in 2023 and 2024 respectively, reflecting later-stage activity without formal series designations.
Seed-stage deal flow remains active — Machine Discovery raised $6M in September 2023 and Allia closed $2M in June 2025 — while the most recent entry, Salience Labs, recorded an undisclosed venture round in October 2025. Across the dataset, round sizes and stages vary considerably, pointing to an Oxford AI cohort that includes both early-formation companies and growth-stage businesses with multiple prior institutional raises.
