The British Business Bank is a UK government-owned economic development bank, not a traditional VC. Its core mission is to address market failures in the provision of finance to smaller UK businesses by acting as a fund-of-funds, co-investor, and guarantor. Through programmes like British Patient Capital and Enterprise Capital Funds, it invests across all stages from seed to scale-up, backing a diverse range of sectors to increase the supply and diversity of long-term patient capital. Its unique position as a government-backed entity allows it to focus on unlocking growth and building a more robust funding ecosystem for UK enterprise.
