Investment thesis
Avonmore is an early-stage angel investor writing first cheques of £50,000–£250,000 into pre-seed and seed companies. It looks for strong founding teams with deep domain knowledge, technical or IP defensibility, and commercial traction or a clear path to it. Target companies are UK or Europe-based and have raised less than £1M of institutional capital previously. The firm focuses on B2B SaaS, AI, infrastructure, deep tech and sector-specific platforms. Roughly 90% of investments are in the UK and Europe, though it is open-minded on where customers are located. Avonmore has no external investors but syndicates larger rounds with high net worth individuals, family offices and VC funds.
