Theo raises €25M to scale their AI system that operates real estate

Existing investor Insight Partners doubles down, with funds and accounts managed by BlackRock providing a debt facility. The raise follows a year of 400% revenue growth.

Real estate is the largest asset class in the world. But ownership feels like a full-time job. Phone calls, paperwork and a myriad of service providers: property managers, brokers, insurers. Each siloed in their own decades-old software and processes.

Theo replaces all of that with one system that gets the job done. From bookkeeping to maintenance to letting and sales, it actually operates, instead of just creating another ticket that never gets resolved.

Today the company announced its €25M Series A: an equity investment from existing investor Insight Partners, which pre-empted the round, and a debt facility from funds and accounts managed by BlackRock. Total funding now stands at €36M. The round follows a year in which Theo grew revenue 400%. Today it serves more than 25,000 apartments on its Portal.

At the heart of Theo, its AI platform Prosa resolves tenant complaints, commissions repairs, approves invoices and closes the books. Industry veterans oversee the system and step in to validate critical decisions and make complex judgment calls. Human interventions create a feedback loop that refines underlying AI models. Underneath, a contextual knowledge graph grows with every interaction, creating a digital twin of the physical world.

"Owning real estate should be simple. You own an asset. But somewhere along the way, owning it came to mean managing an army of brokers, managers, insurers and paperwork. Real estate is a really complex asset class. It was simply too messy for traditional software, which struggles with these complexities," said Jona Schaeffer, Founder and CEO of Theo. "AI is the first technology that can handle that complexity. So we built the system that takes it all off your hands. You own it. Theo does the rest."

"It's been great to see the Theo team execute against their ambitious vision. Theo is what happens when an exceptional team points AI at a market this large and this slow to change. We spend our time looking for partners like them, transforming a fragmented customer experience into an integrated and delightful one. We are fortunate to have Theo in our portfolio," said Richard Matus, Principal at Insight Partners.
