AI system that operates real estate for property owners
About Theo
Theo (formerly hallo theo) is a Berlin PropTech company founded in 2023 that builds Prosa, an AI system that operates real estate for owners—handling bookkeeping, maintenance, letting and sales on a proprietary knowledge graph of physical assets rather than only creating tickets for siloed vendors. Industry specialists oversee critical decisions while AI agents resolve tenant issues, commission repairs, approve invoices and close the books; the platform serves more than 25,000 apartments. In June 2026 Theo announced a €25 million Series A package: equity from existing investor Insight Partners, which pre-empted the round, plus a debt facility from funds and accounts managed by BlackRock, bringing total funding to €36 million after roughly 400% revenue growth.
