Adeline Arts and Science

Adeline Arts and Science is a London-based family office and investment company that backs early-stage technology founders, with a particular focus on AI and other areas where conviction and speed matter more than committee process. Incorporated in 2021 and registered at 116 High Holborn, the firm is structured as an open-ended investment vehicle operating outside the constraints of a traditional VC fund cycle.

The firm is known for its operator-led investment approach and a deliberately fast decision-making process, often writing first cheques into rounds it has high conviction on. Recent portfolio investments include Ralio, an AI agent verification platform building infrastructure for autonomous financial agents, where Adeline backed the company after meeting the team during Antler's 2025 cohort.

Adeline's investment team brings operator and investor experience, including Investment Manager Jaysri Thangam, an Oxford Saïd MBA who joined to lead early-stage deals across the portfolio. The firm operates with the flexibility of family office capital while engaging actively with the UK early-stage and angel ecosystem.
