Summary
Northern Gritstone, the Leeds-headquartered venture capital firm focused on deeptech and life sciences investments in northern England, has announced a £20 million rolling close of additional ordinary share commitments, expanding its permanent capital base to £382 million. This latest tranche builds directly on the firm's April 2025 close of £362 million, representing continued momentum in a subdued venture fundraising environment across Europe.
The British Business Bank has anchored the round as cornerstone investor, committing £10 million to the new tranche. This commitment elevates the state-backed institution's total investment in Northern Gritstone to £40 million, cementing its position as the single largest institutional backer of UK venture and venture growth capital funds. Andrew Law, chief executive of London-based hedge fund Caxton Associates, has similarly increased his own commitment, though the exact size of his additional stake remains undisclosed. These commitments from existing shareholders signal sustained confidence in the firm's investment thesis and operational execution.
The rolling close represents the opening phase of a broader fundraising programme Northern Gritstone intends to execute throughout 2026. This phased approach allows the firm to continue capital deployment while securing additional commitments from its institutional backer and other investors, a notable demonstration of conviction given the broader contraction in European venture capital activity during the period.
Since its launch in May 2022, Northern Gritstone has deployed capital into 51 portfolio companies spanning core deeptech and life sciences verticals: semiconductor design and manufacturing, advanced materials, secure computing, artificial intelligence, healthtech, and gene therapies. The portfolio demonstrates significant concentration in spinouts from the Northern Arc university consortium—Leeds, Liverpool, Manchester, and Sheffield—which collectively generate approximately £800 million in annual research funding, with 92 percent rated as world-leading or internationally excellent by assessment standards.
Northern Gritstone chair Lord Jim O'Neill emphasized the firm's strategic focus on converting university research into scaled global enterprises, while chief executive Duncan Johnson highlighted the achievement of securing new capital commitments despite challenging fundraising conditions, positioning the firm for continued deployment and follow-on investment activity throughout 2026.
