Supa raises GBP 21m seed to rebuild UK residential block management with AI
Coming out of stealth after about a year, Supa keeps local firm brands, automates admin and says managers can spend more time in buildings instead of on paperwork.
London-based Supa has raised GBP 21 million in seed funding co-led by 2150 and OpenOcean, with KOMPAS VC, Actia Capital Partners, HEARTFELT and angels participating. Tech.eu reported that the package also includes a debt facility from a major UK lender.
Rather than selling software into the sector, Supa acquires local block management firms, keeps their identities and overlays an AI-native operating layer for repairs, service charges, safety compliance and contractor coordination. Tech.eu said the company manages about 20,000 homes through seven local firms and has grown revenue more than 700% since its first two acquisitions in late 2025.
Coming out of stealth
Co-founders Calum Brannan (CEO) and Alexis Johnson said in the company post that they spent about 12 months building quietly before announcing the round. Supa's Moorgate address puts it in the City of London. The firm presents itself as rebuilding how residential buildings are run rather than shipping another proptech SaaS tool into a fragmented market of small managers.
Tech.eu described a UK block management market under pressure from rising service charges, heavier admin and higher resident expectations, with many small firms still running on outdated systems. Supa's bet is that buying those firms and modernising operations from the inside is faster than hoping they adopt software on their own.
How the model works
According to Tech.eu, Supa retains local brands and integrates AI that schedules repairs, reconciles service charges, maintains safety records and coordinates contractors. The company claims the technology can cut the time managers spend on administration by up to 90%; that figure is Supa's own claim, not an independently audited metric.
"We're doing the opposite. We keep the local firms, take the admin off their desks, and put managers back inside buildings instead of behind a phone queue. Everyone should know what their service charge pays for, and get an answer when they call," Brannan said, as quoted by Tech.eu.
In their own announcement, Brannan and Johnson argued that millions of people live in buildings managed by an industry that has barely changed in decades, and that hardworking property managers are buried under administration instead of looking after people and buildings. Keeping the human side of management while removing repetitive tasks is the product thesis.
Portfolio so far
Tech.eu named Hunters in Sussex, FW Block Management in Hertfordshire and Lamberts in London among seven local firms in the group. Combined, they manage roughly 20,000 homes. Revenue growth of more than 700% since the first two late-2025 acquisitions shows how quickly an acquisition-plus-software model can compound when the base businesses already collect management fees.
Investors and capital structure
The equity round was co-led by 2150 and OpenOcean. KOMPAS VC, Actia Capital Partners and HEARTFELT joined, alongside angels. Tech.eu's note of an accompanying debt facility from a major UK lender means the GBP 21 million headline is not pure equity alone; the company did not disclose the split between equity and debt in the sources reviewed. Tech Funding News also covered the seed as a sizeable early cheque for UK proptech.
Why it matters for European founders and investors
Buy-and-build plus AI is becoming a common European playbook in fragmented services. Supa's twist is keeping local trust brands while centralising the dull workflows that drive cost and poor resident experience. That is closer to a multi-local operating company than to a classic SaaS land-and-expand motion.
Proptech and vertical AI rounds remain thick on the ground across Europe. For more early-stage capital news, see our funding section. Founders watching regulated, relationship-heavy niches should note how Supa uses acquisitions as distribution for the AI layer rather than trying to displace local managers outright.
What happens next
Supa plans more acquisitions and further development of its AI platform across the portfolio. The company says it is hiring and open to talks with owners of strong local building management businesses who want to join a larger platform.
