The British Business Bank has committed £50 million to Longwall Venture Partners’ fresh £100 million fund.

It marks British Business Bank’s fourth commitment to the firm.

Longwall’s exits include OrganOx, which generated 19.2x return on investment when it was sold for over $1.5 billion, including for British Business Bank.

The British Business Bank has anchored Longwall Venture Partners’ latest vehicle, Longwall 4, with £50 million.

The cornerstone commitment comes via the institution’s Enterprise Capital Funds programme and marks its fourth investment into the Oxford-based deeptech investor since the firm’s inception in 2008.
