Adeline Arts & Science

Adeline Arts & Science is a London-based family office, incorporated in January 2021, that funds early-stage tech startups, creative projects, and scientific research. The firm takes a 5–10 year investment horizon and backs pre-seed to Series A companies that are market disrupters or use science and technology to build systemic leverage. Its average cheque size is £150K, with follow-on participation in later rounds. Adeline describes itself as sector-agnostic, investing across frontier technologies, infrastructure tools, AI, and deep science-led solutions, while also supporting film and publishing in the arts. Portfolio companies include TaiSan (sodium batteries), Capsa AI (AI for private capital), and NEX Health Intelligence (infection intelligence for hospitals). The team is led by founder Des Tan, a mathematical biologist and former advisor to the Australian Prime Minister's Strategy Division. Founders can apply via a pitch form on the website.
