Our take
The global demand for renewable electricity is skyrocketing, reflecting the new commitments that are necessary for cutting down carbon emissions. While most companies, including smaller ones, are seeking access to renewable energy, as it stands sustainable energy is only accessible to companies with larger financial means.
Berlin-based Trawa is looking to challenge this narrative by building a digital, data-driven energy provider that helps businesses decarbonise their electricity consumption. With a particular focus on SMEs in the manufacturing and processing sectors, Trawa is enabling companies to make the switch to green electricity and join a growing circle of enterprises committed to the future of sustainability.
The startup has secured substantial funding over the years that will help accelerate its growth. While Trawa is still relatively new to the scene, it's making waves in its mission to revolutionise renewable energy and looks set for a bright future.
