The British Growth Partnership has secured £200m from pension providers including Aegon UK, Cushon, and M&G. The British Business Bank serves as general partner, marking its first external fundraising. This coalition bridges the gap between Britain's substantial savings pool and its growing startup ecosystem, bringing pension capital into venture capital at unprecedented scale.

The initiative connects to the Mansion House Accord, where 17 UK pension providers committed to allocating 10% of defined contribution funds to private markets by 2030. BBB already manages billions through its Patient Capital Funds across 93 funds. Louis Taylor, BBB CEO, emphasizes connecting domestic savings with British innovation to maximize economic value.

The fund's first deployment is an £8m investment into London-based Wayve, an autonomous driving software company. The BBB previously participated in Wayve's $1.2bn round this February. UK Secretary of State Peter Kyle views this as unlocking necessary capital for cutting-edge innovators to compete globally while growing domestically.
