Supa, a London company that buys residential block-management firms and runs them on its own AI software, has raised £21m (about $28m) in seed funding. The round was announced on 4 November 2026.
The money comes in two parts. The equity was co-led by 2150 and OpenOcean, with KOMPAS VC, Actia Capital Partners, HEARTFELT and a group of angel investors. A debt facility comes from what the company described as a major UK lender, which it did not name. Supa did not say how the £21m splits between equity and debt or disclose a valuation.
The dollar figure is the one given by News on the Block.

What Supa does
Block managers run the shared parts of apartment buildings for the residents and freeholders who own them: they arrange repairs, collect and account for service charges, keep safety records and deal with contractors. In the UK the work is mostly done by small local firms.
Supa buys those firms, keeps their local brands and moves their operations onto its own software. The software schedules repairs, reconciles service charges, tracks safety compliance and chases contractors. The company claims it can cut property managers' admin time by up to 90%.
Supa says it now manages about 20,000 homes through seven local firms. Firms named in coverage include Hunters in Sussex, FW Block Management in Hertfordshire and Lamberts in London. Supa said revenue has grown more than 700% since its first two acquisitions in late 2025.
Who is behind it
Supa was founded by chief executive Calum Brannan and Alexis Johnson, its chief product and technology officer. The pair previously built Howsy, a digital lettings and property management company they sold to Dexters in 2022, according to News on the Block. The team also includes founding engineer Gaspard Perrot, formerly of Signal AI, and Mark Opzoomer, a former Yahoo executive, is chairman.
"Residents are paying more every year and too often getting less," Brannan said in the announcement. He told Tech Funding News that the company keeps the local firms, takes the admin off their desks and puts managers back inside buildings.
"Everyone should know what their service charge pays for, and get an answer when they call," Brannan said. Finella Taylor, chief executive of FW Block Management, said Supa had not wanted to rebrand her firm but to keep its identity.
Rahul Parekh, a partner at 2150, said property management runs on tools that feel decades out of date. Sam Hields, a partner at OpenOcean, called Supa one of the clearest examples of AI improving a real-world service at scale. Sebastian Peck, founding partner at KOMPAS VC, said Supa is using agentic AI and economies of scale to lift industry standards.
What the money is for
Supa will use the funding to buy more block-management firms and to keep building its AI platform, Tech.eu reported.
The approach, sometimes called an AI roll-up, means buying established service businesses that already have customers and using software to run them more cheaply. Supa has not published data to back its admin-time and revenue figures, which come from the company, and it did not disclose its headcount or founding year.
