Sherry Coutu
Sherry Coutu CBE is a prominent angel investor and entrepreneur known for championing the UK’s scale-up ecosystem. Originally from Canada, Coutu moved to the UK and in 1994 founded Interactive Investor, an online brokerage, which she led to an IPO in 2000.

In 2014, she authored the landmark Scale-Up Report for the UK government, highlighting the economic importance of helping startups grow into larger firms. This led her, alongside LinkedIn’s Reid Hoffman, to found the ScaleUp Institute in 2015 – a nonprofit that provides resources, mentorship, and policy advocacy for scaling businesses. Coutu also founded Founders4Schools and Digital Boost, initiatives connecting students and small businesses with experienced entrepreneurs. She remains an active non-executive director on multiple boards – past roles include serving on the boards of the London Stock Exchange Group (LSEG), the University of Cambridge Finance Board, and Pearson plc. In the angel community, Sherry Coutu is respected not only for her investments but for her mentorship and network: she often provides board-level guidance and operational mentorship to founders.
