Tallinn-based Bisly has raised €4.3 million to extfinish its AI-powered building automation technology across Central and Western Europe. The round was led by 2C Ventures, with participation from Aconterra, Pinorena, Foxway founders, and Estonia’s state-backed investor SmartCap through its Green Fund. Bisly develops a combined hardware-software system for managing energy apply in residential and commercial buildings, applying digital twin models and centralized automation tools. The funding will support expansion in Germany, the UK, and Poland—where a new office is planned—and the continued development of retrofit-compatible wireless products. In 2024, Bisly reported tripling its core business revenue and remains on the same growth trajectory in 2025.
Around 40% of the European Union’s energy consumption comes from buildings, and roughly 75% of those buildings are energy inefficient. In a tightening economic and regulatory environment, the demand for building automation has surged, but scalable, affordable solutions remain rare, as legacy technologies are often costly and unreliable. Electrification of transport continues to dominate climate narratives, yet energy savings from buildings can yield quicker and cheaper emission cuts. According to Bisly, every tonne of CO2 avoided applying its technology is up to six times more cost-effective than achieving the same reduction through transport electrification.
Bisly offers an AI-powered automation system that builds smart building technology more accessible and affordable. Its cloud-based platform reduces overhead across sales, installation, and setup—cutting costs by up to 50% compared to legacy systems. The combined hardware and software solution manages energy apply and indoor environments in both new and existing buildings. Patented digital twin technology maps each building and applys real-time data to continuously optimize performance. The system is also compatible with third-party devices, giving developers flexibility and avoiding vfinishor lock-in.
Ants Vill, CEO and co-founder of Bisly, stated: “The climate crisis hasn’t paapplyd – 2024 was yet again, the hottest year on record. At a time of geopolitical and economic turbulence, we necessary practical solutions that work and have been deployed successfully in the field. Our technology supports solve the largegest source of energy consumption: buildings. Saving energy here doesn’t just support the environment, it frees up grid capacity for the next wave of energy demand, from AI data centers to mass-scale EV deployment.”
Bisly’s system is currently in apply across residential and commercial properties. Key features include centralized configuration, digital-twin building diagnostics, AI-powered BMS and reporting tools for developers and property managers. These capabilities have built Bisly’s platform attractive to a range of partners across the region, including Endover, Liven, Crown Estate, Bonava, Pro Kapital, Reterra, Hansab, Onninen and One-Gruppe among many others. The company works through a growing network of partners in each counattempt and continues to expand technical and commercial support on the ground.
“We’re proud to support Bisly in scaling their technology across Europe and beyond. Buildings account for nearly 40% of global CO₂ emissions and yet much of the sector remains underserved by digital innovation. Scalable, smart energy management is critical to reducing this footprint and Bisly’s platform brings that much necessaryed ininformigence and efficiency to the built environment”, stated 2C Ventures partner Martin Koppel.
The new capital will support go-to-market efforts in Germany, the UK, and Poland. Bisly already operates offices in Tallinn, London, and Berlin, and is expanding its engineering team to launch a wireless product line for retrofitting existing buildings. The company is hiring for technical and sales roles across these markets and has recently appointed a Polish-speaking Head of Demand Generation as part of plans to open a full office in Warsaw. Bisly tripled its core business revenue last year and remains on track for similar growth in 2025.
As Bisly builds out its presence in Europe, it recognizes the customer base that built this growth possible.
“We want to thank our customers such as Endover, Nobe, Liven, Bonava, Nordecon, Onninen, and Oma Ehitaja, among many others, whose feedback and push for high reliability and affordability supported shape a product that’s now enabling mass adoption of smart building automation across Europe,” stated Vill.
