Pulse Analysis

The United Kingdom’s tech investment momentum accelerated in the week of 16‑20 February, with UKTN tracking £99.86 million across seven rounds – a 21 percent jump from the previous week. The surge reflects heightened appetite for artificial‑intelligence solutions and defence‑related satellite technologies, sectors that have benefited from both private capital and strategic public funds. Investors are increasingly viewing UK‑based AI platforms as scalable exports, while NATO‑backed financing underscores the geopolitical value of thermal‑imaging capabilities.

Fyld led the pack with a £32 million Series B, positioning its AI‑driven video risk‑analysis tool for a U.S. rollout and signalling confidence in workplace‑safety automation. Satellite‑imaging specialist SatVu secured £30 million from the NATO Innovation Fund and the British Business Bank, highlighting the commercial potential of space‑based thermal intelligence. Fintech newcomer Stacks raised £17 million to build an agentic finance platform, while SurrealDB’s Series A extension matched that amount to modernise database architectures for generative‑AI workloads. Together, these deals illustrate a diversified capital flow across AI, defence and financial services.

The breadth of funding, from seed‑stage health‑tech ventures like Klaris and Nul to mid‑stage AI and defence firms, suggests a maturing ecosystem that supports both early experimentation and rapid scaling. Regulatory‑focused AI tools and subscription‑based health platforms are attracting niche investors keen on long‑term value creation. As UK policy continues to incentivise deep‑tech and export‑ready startups, the current funding wave is likely to translate into stronger talent pipelines, increased R&D spending, and a more competitive position for Britain in the global tech arena.
