Proptech Startup Supa Raises £21M ($28M) Funding to Roll Up UK Block Management With AI

Supa, the London-based AI-native property management company, has raised £21 million ($28 million) in seed funding co-led by 2150 and OpenOcean, with participation from KOMPAS VC, Actia Capital Partners, and HEARTFELT. The round includes equity funding and a debt facility from a major UK lender. The company did not disclose its valuation.

The funding comes as Supa emerges from stealth after twelve months of building quietly. The company has acquired seven local block management firms—including Hunters in Sussex, FW Block Management in Hertfordshire, and Lamberts in London—and now manages approximately 20,000 homes. Revenue has grown by more than 700% since its first acquisitions in late 2025 .

Startup Overview: Supa

What Supa Is Building in Simple Words

Supa is not building another property management software company. It is buying established block management firms, keeping their names and staff, and replacing their back-office systems with Supa’s own AI software. The software handles repairs, service charge reconciliation, safety checks, and contractor management .

• AI Roll-Up Model: Supa acquires local managing agents, retains their identity and teams, and installs its proprietary AI operating system to automate administrative work .
• Admin Reduction: The company says its software cuts admin time by up to 90%, freeing property managers to spend more time in buildings and responding to residents .
• Resident-Facing Impact: The goal is faster answers, clearer service charges, and better-run buildings—countering a trend where residents pay more but receive less .

Why Supa Matters

• The sector is fragmented and under-digitized: The UK property management sector is worth £37 billion, yet technology has never taken hold. A decade of consolidation has produced bigger portfolios without improving resident experience .
• Service charges are rising faster than inflation: The average service charge in England and Wales reached £2,405 in 2025, up 32.6% in five years versus a 30.9% increase in consumer prices .
• Founders have done this before: Calum Brannan and Alexis Johnson previously built Howsy, the UK’s largest digital property manager, which was sold to Dexters in 2022 .
• Strategic investors validate the model: 2150 and OpenOcean co-led, with KOMPAS VC, Actia, and HEARTFELT participating. The debt facility from a UK lender signals confidence in the acquisition pipeline .

Founder Background: The Howsy Team Building the Third Way

Calum Brannan (CEO) and Alexis Johnson (Chief Product and Technology Officer) co-founded Supa in 2025. They previously built Howsy, a digital property management platform that was sold to estate agency group Dexters in 2022 . They are joined by founding engineer Gaspard Perrot, formerly of Signal AI, and chairman Mark Opzoomer (Yahoo, Trint, Somo) .

Brannan’s framing of the opportunity: “Residents are paying more every year and too often getting less. Bloated portfolios and ageing systems leave residents with their calls going to voicemail. 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” .

Founder Intelligence: What Founders Can Learn from Supa

• Buy the business, keep the brand: Supa doesn’t rebrand its acquisitions. It keeps local names and teams, which reduces friction in deals and preserves relationships with residents. Finella Taylor, CEO of acquired firm FW Block Management, said preserving the company’s legacy was critical to her decision to sell .
• Use AI to improve service, not just cut costs: Supa’s pitch to residents is faster answers and clearer charges. The 90% admin reduction is the enabler, not the product. This framing matters for a sector where trust is the core currency.
• Raise equity and debt together: Supa’s £21M includes both equity and a debt facility from a UK lender. In a roll-up strategy, debt is essential for funding acquisitions without over-diluting equity .
• Build on prior domain expertise: Brannan and Johnson had already built and sold a property management business. They understood the operational pain points and had the credibility to convince managing agents to sell to them.

Investor Intelligence: Why This Round Gets Premium Capital

2150 and OpenOcean co-led the round. Rahul Parekh, Partner at 2150, framed the thesis: “Property management operates with tools that feel decades overdue, and Calum and Alexis saw the opportunity to change that completely. Their vision for Supa is to become the intelligence layer for how buildings are run” .

Sam Hields, Partner at OpenOcean, added: “Supa is one of the clearest examples of AI improving a real-world service at scale. Calum and Alexis are bringing together the technology, the data and the businesses needed to make it work” .

KOMPAS VC, Actia Capital Partners, and HEARTFELT participated, bringing climate-tech, operational, and impact expertise. The debt facility from a major UK lender (undisclosed) validates the acquisition pipeline .

The Road Ahead for Supa

Expansion Targets

With £21 million in capital, Supa will:

• Acquire more local managing agents, continuing the roll-up strategy that has already brought seven firms into the portfolio .
• Invest in technology development, deepening the AI operating system that powers its acquired firms .
• Improve resident response times, targeting same-day answers rather than weeks-long delays .

The Structural Question

Supa’s model depends on a steady supply of managing agents willing to sell. The promise to keep original names and teams is a differentiator in deals, but it also creates a portfolio of distinct brands rather than a unified platform. How Supa balances local identity with operational standardization will determine whether the model scales beyond the first wave of acquisitions.

Competitive Response

Expect:

• Traditional property management consolidators to explore similar AI integration strategies.
• Other proptech roll-ups to emerge targeting the £37 billion UK block management sector .
• Managing agents to become more selective about buyers as demand for their businesses increases.
• Supa’s moat: founder track record + AI operating system + debt-funded acquisition capacity + local brand preservation model.

Conclusion

Supa’s £21 million seed funding validates the thesis that AI can transform block management by buying the businesses and upgrading the back office, not selling software to incumbents. The company’s seven acquisitions, 20,000 homes under management, and 700% revenue growth demonstrate that the roll-up model is working—and that managing agents are willing to sell to a buyer who preserves their identity.

Market tailwinds favor Supa: rising service charges, leasehold reform adding pressure on managers, and a £37 billion sector that has resisted digitization for decades. The company’s experienced founders, AI-native operating system, and equity-plus-debt funding structure position it to scale as the intelligence layer for UK block management.
