How a biochemist turned management consultant became one of the UK's most experienced angel investors — and what new angels can learn from his journey.When Simon Blakey made his first angel investment in 2000, the startup ecosystem looked radically different. There was no AngelList, no Seed Legals, and certainly no standardised term sheets. Finding deals meant subscribing to the "Venture Capital Report" — a physical, green-bound publication that featured just two or three opportunities with basic due diligence notes.Fast-forward 25 years, and Blakey has completed over 100 funding rounds across 50-60 investments, ranging from robotics companies eventually acquired by GE Aviation to ticketing platforms processing over a billion in GMV. As Chair of the Investment Committee at Playfair Capital and a board member of Cambridge Angels, he's witnessed the entire evolution of early-stage investing.His journey offers invaluable lessons for today's angel investors, particularly those making the transition from successful entrepreneurship to investing.
