Oxara develops cement-free, low-carbon binders made from locally available excavation and demolition waste, addressing one of the largest unresolved climate challenges in the built environment. Medley, the entrepreneurial venture capital fund backed by the founders of Too Good To Go, identified Oxara’s approach as a combination of technological innovation, industrial scalability, and real-world applicability — ultimately leading to an investment by the end of 2025.
Medley Ventures is known for backing companies that turn systemic inefficiencies into scalable, commercially viable business models. Its founders built Too Good To Go by addressing food waste and transforming it into a global platform that aligns economic value with environmental impact. Medley saw a comparable pattern at Oxara, applying the same entrepreneurial logic to one of the most carbon- and resource-intensive industries worldwide: construction.
Rather than pursuing incremental optimisation, Oxara focuses on unlocking underutilised resources at scale. While Too Good To Go created value by rescuing surplus food already produced, Oxara replaces carbon-intensive cement — responsible for around 8% of global CO₂ emissions — with circular binders derived from construction waste that is already available but largely unused. Oxara’s technology integrates seamlessly into existing production processes, enabling significant CO₂ reductions while remaining cost-competitive and compatible with established construction practices.
“What convinced us was the vision behind Oxara: world-class engineering, real industrial impact, and genuine hope for a better future of construction. By making cement unnecessary and turning waste into value, they show that innovation can change the way we build.”

“This investment is a strong validation from entrepreneurs who have built one of Europe’s most impactful sustainability companies,” said Gnanli Landrou, CEO and Co-Founder of Oxara. “The founders of Too Good To Go bring hard-earned experience in scaling mission-driven businesses globally without compromising economic fundamentals. Their conviction reinforces our belief that sustainable construction must be practical, scalable, and economically viable.”
With Medley Ventures joining as an investor, Oxara will accelerate product development, certification pathways, and industrial partnerships, enabling broader deployment in Switzerland and across international construction markets.
Oxara is in the process of raising CHF 20 million in a Series A funding round with a targeted close by March 2026. Funds raised in the Series A will be allocated to scaling production capacity to meet current customer demand, advancing product certification and industrial partnerships, building a carbon credit revenue stream, and bridging temporary operating losses to reach break-even by 2028.
