The Estonian provider of scalable smart building automation solutions, Bisly, has secured €4.3 million in funding. This investment will aid Bisly’s growth in the DACH region and the UK and facilitate a new office opening in Poland, a rapidly expanding market for smart building technology. Bisly already dominates the Estonian market, with its systems installed in most new residential apartments sold in 2024.
Buildings comprise approximately 40% of the EU’s total energy usage, yet about 75% are energy inefficient. As economic pressures increase and regulations become more stringent, the demand for building automation is rising. However, scalable, cost-effective solutions are limited due to existing systems being expensive and unreliable. While transport electrification is a prevalent topic in climate discussions, enhancing building energy efficiency offers faster and more economical emissions reductions. Bisly reports that each tonne of CO₂ reduced with its technology can be up to six times more cost-effective than reductions achieved through transport electrification.
Bisly tackles these challenges with its AI-powered automation system, making smart building technology both affordable and accessible. The cloud-based platform simplifies sales, installation, and setup, reducing costs by up to 50% compared to traditional systems.
The company’s integrated hardware and software solution manages energy use and indoor environments in both new and existing structures. Central to this is Bisly’s patented digital twin technology, which creates a virtual model of each building using real-time data for continuous performance optimization. The system’s compatibility with third-party devices offers developers flexibility and prevents vendor lock-in.
Ants Vill, CEO and co-founder of Bisly, stated:
“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 centres to mass-scale EV deployment.”
Bisly’s system is currently utilized in both 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 attracted numerous partners across the region, including Endover, Liven, Crown Estate, Bonava, Pro Kapital, Reterra, Hansab, Onninen, and One-Gruppe.
The company collaborates with a growing network of partners in each country and continues to expand local technical and commercial support.
“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 helped shape a product that’s now enabling mass adoption of smart building automation across Europe,” added Vill.
The funding round, led by 2C Ventures, saw participation from existing investors such as Aconterra, Pinorena, the founders of Foxway, and SmartCap – Estonia’s state-backed VC fund, backed by the EU’s NextGenerationEU recovery plan.
Martin Koppel, Partner at 2C Ventures, commented:
“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-needed intelligence and efficiency to the built environment.”
The new investment will bolster market efforts in Germany, the UK, and Poland. Bisly currently has offices in Tallinn, London, and Berlin, and is expanding its engineering team to develop a wireless product line for retrofitting existing buildings.
Bisly is growing its team with technical and sales hires in key regions and has appointed a Polish-speaking Head of Demand Generation in anticipation of opening a full office in Warsaw. The company tripled its core revenue last year and anticipates similar growth in 2025.
