Also worth knowing

Waterspring Ventures is an EIS fund registered in Cardiff that backs around three Welsh companies a year. It followed on in the October 2026 tourhub round, having first put £450,000 into the company in 2023 alongside the Development Bank of Wales, though its Cardiff AI record is thinner than the funds above. On the international side, Soulmates Ventures led Antiverse's Series A, a useful signal that Cardiff deep tech can pull in overseas leads. The Development Bank also runs an Angel Co-investment Fund that sits alongside private angels, which is how a slice of the DataWollet round came together.

Other support in the region

The Welsh Government announced a £2.1 million package in January 2026 to help Welsh SMEs adopt AI, including an AI awareness and adoption programme through Business Wales and an AI Pollination Project with the Hartree Centre Cardiff Hub and Cardiff University's Digital Transformation Innovation Institute. Tramshed Tech in Grangetown runs a Founder Academy bootcamp and an AI Enable programme for Cardiff Capital Region SMEs, funded by UK Government through the Barclays Eagle Labs Ecosystem Partnership Programme. The same venue hosted the Welsh launch of the £500 million UK Government Sovereign AI Fund in May 2026, which backs AI founders from seed to Series A.
