UK proptech Supa has raised £21m in seed financing, combining an equity round co-led by 2150 and OpenOcean with a debt facility from a UK lender, to fund further acquisitions of residential block management firms. The company already oversees about 20,000 homes through seven local agencies and reports revenue growth of more than 700% since its first deals in late 2025.
Supa is pursuing a buy-and-build model in one of the most fragmented corners of UK property. Rather than selling software to block managers, it acquires them outright, keeps their local brands and staff, and moves their back-office work onto its own AI platform.
The approach targets a sector dominated by small operators, many with fewer than ten employees, that are under pressure from rising service charges, heavier compliance workloads and residents demanding faster responses.
The deal
The £21m package is split between equity and debt, although the company has not said how much sits on each side. 2150, the London-based fund focused on urban and built-environment technology, and OpenOcean co-led the equity tranche.
KOMPAS VC, Actia Capital Partners and HEARTFELT also took part. The debt facility comes from what the company describes only as a major UK lender. Valuation and ownership terms were not disclosed.
The structure fits the model. Roll-up strategies tend to rely on debt to fund acquisitions, since the targets are cash-generative businesses, and keep equity for the technology build. For a company at seed stage, a total of £21m is large, and it reflects the fact that Supa is buying revenue rather than waiting for software sales to grow.
The portfolio
Supa's seven firms include Hunters in Sussex, FW Block Management in Hertfordshire and Lamberts in London. Together they manage about 20,000 homes.
The platform automates repair scheduling, service-charge reconciliation, safety compliance records and contractor coordination. The company says this can cut the time managers spend on admin by up to 90%.
Co-founder and chief executive Calum Brannan said the aim was to keep local firms in place while stripping out the administrative burden, so that managers spend their time in buildings rather than on the phone. He added that residents should be able to see what their service charge pays for.
What's next
The new capital will fund more acquisitions alongside further development of the AI platform. With its first two deals made in late 2025 and seven firms now in the group, Supa has been adding businesses at roughly one every two months.
The bigger test will be whether the efficiency gains hold up across a larger estate, and whether the model can earn software-style margins from what is still a services business. Leaseholder scrutiny of service charges is also rising, so Supa's promise of transparency will be judged closely as the portfolio grows.
