Estonia-based smart building automation firm Bisly has raised €4.3 million in a funding round aimed at expanding its market presence across Central and Western Europe.
The investment was led by 2C Ventures, with participation from existing backers including Aconterra, Pinorena Capital, the founders of Foxway, and Estonia’s state-supported SmartCap Green Fund. The Green Fund is financed in part by the EU’s NextGenerationEU recovery initiative.
The company plans to use the funds to increase its footprint in the DACH region and the United Kingdom, while also establishing a new office in Poland. According to Bisly, Poland is one of the fastest-growing markets for building automation technologies. In its home country of Estonia, Bisly already holds a significant share, with the majority of new residential apartments sold in 2024 equipped with its automation systems.
Buildings are responsible for approximately 40% of the European Union’s total energy consumption, and about 75% of existing buildings are considered energy inefficient. As both regulatory and economic pressures increase, demand for intelligent automation systems is growing.
However, many of the existing solutions are expensive and outdated. While much of the climate discourse centers on transport electrification, Bisly points out that energy savings in buildings could offer quicker and more cost-effective ways to reduce emissions. The company estimates that each tonne of CO2 avoided through its platform can be up to six times cheaper than achieving the same reduction via electric transport.
Bisly provides a combined hardware and software platform designed to simplify building automation at scale. The system, powered by AI, manages energy usage and optimizes indoor environments in both new and existing buildings.
Its platform includes patented digital twin technology, which creates a virtual model of a building and continuously improves performance through real-time data analysis. The platform also allows compatibility with third-party systems, enabling flexibility for developers and reducing the risk of vendor lock-in.
Bisly reports that its cloud-based configuration reduces installation, setup, and operational costs by up to 50% compared to legacy solutions.
The new capital will support go-to-market efforts in Germany, the UK, and Poland. Bisly currently operates out of offices in Tallinn, London, and Berlin and is expanding its engineering team to develop a wireless solution tailored for retrofitting older buildings.
As part of its Poland expansion, the company has hired a Polish-speaking Head of Demand Generation and is planning to open a Warsaw office. Bisly is actively hiring across technical and commercial roles.
Bisly’s automation systems are already deployed in a mix of residential and commercial projects. The company’s customer list includes developers and partners such as Endover, Liven, Crown Estate, Bonava, Pro Kapital, Hansab, Onninen, and One-Gruppe.
Its platform includes centralized configuration, diagnostics through digital twins, and AI-powered building management tools for developers and facility operators.
Martin Koppel, partner at 2C Ventures, noted the market potential:
“Buildings are responsible for nearly 40% of global carbon emissions, yet much of the sector has seen limited digital transformation. Bisly’s scalable platform addresses this gap with intelligent energy management for the built environment.”
Ants Vill, Bisly’s co-founder and CEO, highlighted the urgency of energy solutions:
“2024 marked another record year for global temperatures. With growing energy demands from sectors like AI data centers and electric mobility, improving efficiency in buildings is critical. Our solution aims to meet this challenge practically and affordably.”
Vill also acknowledged the company’s early adopters and partners:
“Our customers—such as Endover, Nobe, Bonava, and others—have helped shape a reliable, scalable solution that supports wider adoption of smart building technologies across Europe.”
