Bisly, an Estonian deep tech company specializing in smart building automation, has announced securing a €4.3M in funding to expand its operations across Central and Western Europe. The funds will be used to deepen the company’s presence in DACH and the UK, and to open a new office in Poland – one of the fastest-growing markets for smart building infrastructure.
The round, led by 2C Ventures, included participation from existing investors, such as Aconterra, Pinorena, the founders of Foxway, and SmartCap – Estonia’s state-backed VC fund, whose Green Fund investment is supported by the EU’s NextGenerationEU recovery plan.
Bisly offers an AI-powered automation system that makes smart building technology more accessible and affordable. Their 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 use and indoor environments in both new and existing buildings. Patented digital twin technology maps each building and uses real-time data to continuously optimize performance. The system is also compatible with third-party devices, giving developers flexibility and avoiding vendor lock-in.
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. In the meantime, scalable, affordable solutions remain rare, as legacy technologies are often costly and unreliable.
As noted in the company’s announcement, electrification of transport continues to dominate climate narratives, yet energy savings from buildings can yield faster and cheaper emission cuts. Every tonne of CO2 avoided using Bisly’s technology is up to six times more cost-effective than achieving the same reduction through transport electrification.
“The climate crisis hasn’t paused – 2024 was yet again, the hottest year on record. At a time of geopolitical and economic turbulence, we need practical solutions that work and have been deployed successfully in the field. Our technology helps solve the biggest source of energy consumption: buildings. Saving energy here doesn’t just help the environment, it frees up grid capacity for the next wave of energy demand, from AI data centers to mass-scale EV deployment,” notes Ants Vill, CEO and co-founder of Bisly.
Bisly is already the leading provider in Estonia, with a majority of all new residential apartments sold in 2024 featuring the startup’s automation components.
Bisly’s system is currently in use across residential and commercial properties. Key features include centralized configuration, digital twin for building diagnostics, AI-powered BMS, and reporting tools for developers and property managers. These capabilities have made their 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. Bisly works through a growing network of partners in each country and continues to expand technical and commercial support on the ground.
