Street Group Hits £200m Valuation as Hg Backs AI-Native Agency OS

The deal, announced 22 July, puts a number on something the market has been debating all year: what does genuinely embedded agency AI actually cost? The answer, at least for Street Group, is north of £200m.

What Street Group Actually Built

Street is not a bolt-on tool vendor. Founded in 2015 by siblings Tom and Heather Staff, the Manchester business has assembled what it calls an integrated operating system for agents: a core CRM under the Street.co.uk brand, a prospecting and lead-generation platform called Spectre, and, most recently, Cortex, an AI-agent orchestration layer that sits above both.

Cortex is the piece that changes the staffing calculus. Rather than assisting agents, the platform lets agencies build and deploy AI agents that carry out tasks: handling enquiries, progressing sales, running compliance checks, generating marketing content. By May, more than 300 agencies had already begun onboarding. Street's own co-founder described it as "a completely new way of running an agency," not an add-on.

The distinction between AI-assisted and AI-native platforms matters commercially. An AI-assisted CRM generates content but cannot see a live pipeline or flag a compliance gap. An AI-native system, where intelligence is wired into the operational core, can surface the right action at the right moment without anyone asking it to. That architecture is what Hg is paying for.

The Hg Investment

Hg's listed vehicle HgCapital Trust is committing approximately £7m directly, with additional institutional co-investors participating via the Mercury Fund. Tom and Heather Staff retain majority control. The founding team is reinvesting substantially alongside Hg, which typically signals confidence the cap table is not cashing out early.

Previous backer PXN Group (formerly Praetura Ventures) is realising a return in what one deal adviser described as a strong exit for local investors. Street was founded with Manchester capital and exits, at least partially, with Manchester capital intact.

For context on scale: Street Group now serves more than 4,000 estate agency offices across the UK. Agency CRM churn is structurally low; switching costs once workflows and data are embedded are high. Hg's Mercury Fund, which targets software businesses at precisely this inflection point, would understand the recurring-revenue arithmetic well.

The Wider Consolidation Picture

Street's raise comes alongside a separate but related trend: AI-enabled acquirers absorbing independent lettings books. Dwelly, the London-based AI-first lettings platform backed by General Catalyst's £69m round in February, has completed eight acquisitions in 2026 alone. Its eighth deal, picking up the lettings book of West Midlands firm AP Morgan in mid-July, took its portfolio to nearly 14,000 fully managed properties. The model: acquire fragmented independents, layer a proprietary AI operating platform across them, and compress admin costs while expanding margin.

Dwelly's own data claims tenants are found in under two weeks against an industry average of roughly three, and maintenance issues resolved in 20 days versus a typical 50. Those figures are company-supplied, so treat with appropriate scepticism. But the direction of travel is consistent with what Street's Cortex is selling agents on the software side: the same admin hours, fewer staff, better margins.

Two models are converging on the same structural inefficiency in UK lettings. Street sells the operating system to independent agents who stay independent. Dwelly acquires the agent and runs the OS itself. Both require AI infrastructure that works at the workflow level, not at the demo level.

Brand Thin, Registrations Down

AI Business Dispatch analysis of Companies House and IPO data (as of July 2026) adds a structural footnote. New SIC 68.20 company formations in Q3 2026 stand at 3,309, down 77.8% on the prior period, a sharp contraction in new market entrants to the lettings sector. UK trademark filings in Nice Class 36 (financial and real estate services) total just 660 for Q3 2026, also down 72.3%. Perhaps most striking: 99.8% of active SIC 68.20 companies hold no Class 36 trademark at all.

That last figure is a branding story as much as a legal one. The proptech players scaling fastest, Street Group and Dwelly among them, are building brand equity precisely because the long tail of independents has none registered. When an AI platform acquires or displaces those independents, there is rarely a trademark asset to negotiate around.

For investors watching sector multiples, the Street valuation is a useful peg. Hg paid above £200m for a business serving 4,000 branches across CRM, prospecting and AI orchestration. The revenue multiple is undisclosed, but for a high-retention vertical SaaS with demonstrable AI differentiation in a market that has barely started digitising, the number is defensible.

What it is not is a ceiling.
