British Business Bank

Activity from announced rounds

All recorded activity

British Business Bank is the UK’s economic development bank, supporting business access to finance through investment programmes, funds and financing partners.

Its Future Fund: Breakthrough programme, delivered by British Patient Capital, co-invests with private investors in later-stage, R&D-intensive UK companies. It targets technologies such as quantum computing, cleantech and life sciences, where development requires substantial capital.

Applications to that programme come from a qualifying sponsor investor, rather than directly from the company. The published criteria require a round of at least £30 million, with the programme contributing no more than 30% on the sponsor investor’s terms.
