On Wednesday 24 June 2026, LEKO Labs, a Luxembourg-based carbon-negative construction startup, announced the completion of a new funding round with its historical shareholders and partners to strengthen its financial position and support the company's continued growth and industrial development.

According to the company, the funding round follows LEKO's return to operational break-even in 2025, when it reported a positive EBITDA of €0.7 million after several years of technological and industrial investment. LEKO noted that the result also reflects the impact of a restructuring process carried out during a particularly challenging period for the construction sector.

With the latest transaction, the total amount of funds raised and deployed since 2017 now exceeds €30 million. Nearly ten years after its founding, LEKO has accumulated more than one million engineering hours, secured nine patents and delivered around 500 homes across Europe.

The company added that it is supported by an international team of around twenty employees working across construction, engineering, industry, design and finance. The investments have enabled LEKO to establish a portfolio of technologies and intellectual property in Luxembourg dedicated to the decarbonisation of the construction sector, while also developing advanced industrial capabilities and creating high-value jobs.

François Cordier, Founder and CEO of LEKO, said: "This operation reflects our shareholders' renewed confidence in the trajectory we have been pursuing for nearly ten years. The continued commitment of our historical investors and partners validates the work accomplished, enables us to consolidate our financial base, and allows us to approach the next phase with strengthened industrial execution capacity.” He added: "The interest shown by new investors reflects the maturity of our technology and the commercial traction of our industrial model. It will enable us to reach a new milestone in our European deployment."

Keith O'Donnell, a historical investor in LEKO, commented: "What particularly stood out to us was the team's discipline and ability to execute. The construction sector has faced challenging market conditions, yet LEKO has stayed the course, returned to operational profitability and, above all, demonstrated the relevance of its business model. This combination of resilience and commercial traction is what led us to renew our support for the company."

The company also announced that European PropTech investor AMAVI Capital has joined the funding round. AMAVI Capital counts Luxembourg's IKO Real Estate group among its limited partners, placing the investment within the country's innovation ecosystem.

Frédéric Van den Weghe, Managing Partner at AMAVI Capital, said: "Europe must simultaneously address an unprecedented housing shortage and the urgent need to decarbonise construction. LEKO demonstrates that it is possible to act on both fronts through an industrial and technological approach developed in Europe.” He added: "The intellectual property, the automation technologies and the value chains have all been built and developed in the Benelux. This is precisely the kind of European industrial innovation that is essential to support today."

According to LEKO, the company has developed an integrated technological and industrial platform combining low-carbon construction systems, production automation and design software tools for building professionals. Since establishing its activities in Luxembourg in 2017 with the support of Technoport, LEKO said it has benefited from the Grand Duchy's innovation ecosystem, which supports the development of industrial technologies and decarbonisation solutions in line with Luxembourg's economic diversification strategy.
