Why did one VC fund back a 21-year-old hardware firm and an AI startup?
Background
Blossom Capital led two Series A rounds in the same week in July 2026: a £30m round for Bedford propulsion company Greenjets on 21 July, alongside NATO Innovation Fund and NSSIF , and a £22.5m round for London AI company Arrakis three days later on 24 July .
Blossom Capital is a London venture capital firm. The Greenjets round also drew NATO Innovation Fund, the National Security Strategic Investment Fund, Tanglin Ventures and a family office, while Arrakis' round was joined by Accel, GFC, MainObject and Rerail. The two companies sit at opposite ends of the evidence spectrum: Greenjets is a twenty-one-year-old hardware company with patents and aircraft customers, and Arrakis is an early-stage AI company that has not named a public product.
One fund backing both ends of that spectrum within three days says something about where British venture capital is placing its bets, patient patent-backed hardware alongside early, thesis-only AI. The Greenjets round also put two state-security-minded investors, NATO's own fund and Britain's dual-use vehicle, on one aerospace share register beside Blossom's growth capital, a pairing that shapes how patient that capital can afford to be through an aircraft-certification timeline.
