This UK PropTech Startup Just Hit a $250M Valuation — Here's How They Did It

Jan de Vries · 2026-07-24

Street Group, a Manchester-based software company that builds tools for the UK residential property market, just landed a major investment from Hg. The deal values the company at over $250 million (roughly £200 million). It's a big moment for the sibling-led startup, which started life as Agent Software back in 2015. And it tells us something about where the real estate tech space is heading. ### From CRM to AI-Powered Operating System Street Group isn't your average property software provider. They've built what they call an integrated operating system for estate and letting agents. Think of it as the backbone that runs a real estate agency. Their main offerings include: - **Street.co.uk** — a core CRM for managing clients and properties - **Spectre** — a prospecting and lead generation platform - **Cortex** — an AI-native product that lets customers build and orchestrate their own AI agents That last one is key. Cortex isn't just another chatbot. It's a platform that lets agents create custom AI tools tailored to their specific workflows. That's a big deal in an industry that's been slow to adopt new tech. ### The Hg Factor Hg is no small player. They manage over $110 billion in assets and have a portfolio of around 60 businesses worth more than $190 billion combined. Their portfolio companies employ over 140,000 people and grow revenue at an average of 16% annually. Louis Kinsella, a Partner at Hg, put it simply: "Street is exactly the kind of business we love to back. It's a category leader with a technical edge, loved by its customers, and deeply embedded in their daily workflows." That "deeply embedded" part is crucial. Street Group's software isn't a nice-to-have for agents. It's become the central tool they rely on every day. That kind of stickiness is what investors love. ### What This Means for the US Market For US readers, this deal is worth watching. Hg has a strong presence in North America, and they're betting big on property tech. The UK market is similar to the US in many ways — fragmented agency landscape, legacy software, and a growing appetite for AI-driven solutions. If Street Group can crack the UK market (they already serve thousands of branches), a US expansion might not be far behind. And with $250 million in valuation, they have the resources to think big. ### The Founders' Vision Heather and Tom Staff, the sibling co-CEOs, are staying in control. They remain majority shareholders and will continue to lead the company. That's a smart move — it keeps the culture and customer focus that made Street successful in the first place. "We built Street to fundamentally change how estate and letting agents work," they said. "AI is central to that mission." With this funding, they plan to accelerate product innovation and deepen their AI capabilities. Expect to see more Cortex-like tools that put AI power directly into agents' hands. ### The Bigger Picture Street Group's story is part of a larger trend. PropTech is finally moving beyond simple listing sites and into core operational software. Companies that can build deep, integrated platforms — and layer AI on top — are the ones attracting big money. For US professionals in real estate tech, this UK startup is one to watch. It shows that the market for AI-powered property software is real, and growing fast. *Disclosure: Hg is an investor in Street Group.
