Helsinki, Finland

Avenue Biosciences, a transatlantic biotechnology company specialising in novel protein engineering technologies, announced the successful closing of their $2.5M seed financing round. Led by Voima Ventures, with additional participation from Inventure and US angel investors, the funding will accelerate the development of Avenue Biosciences’ platform, designed to improve the efficiency of protein production in the biopharmaceutical industry.

The technology promises to shorten development times and lower costs for critical therapies, making treatments such as monoclonal antibodies, gene therapies, and mRNA-based vaccines more accessible to patients globally. By addressing one of biotech’s biggest challenges—efficient and scalable protein production—Avenue Biosciences’ platform will transform how life-saving therapies reach the market.

“This technology taps into a rapidly expanding biopharmaceutical market, poised for substantial growth,” said Jenny Engerfelt, Partner at Voima Ventures. “By making the production of complex proteins more efficient and affordable, it not only accelerates the development of innovative treatments but also significantly enhances the commercial scalability of these therapies. This positions us to capture significant value while improving access to life-saving medicines across a wider range of diseases.”

Avenue’s proprietary technology screens and optimises signal peptides—the key to guiding protein delivery within cells—using machine learning to enhance efficiency.

Think of the technology like this: You are sending a package through the post. The signal peptide is like the address label, guiding the package (protein) to its destination within the cell. Once delivered, the label is removed, and the package is ready to be used. Avenue Bioscience’s technology works like a smart GPS, optimising and improving delivery routes (signal peptides).

The result? A platform that accelerates the development of complex proteins critical for next-generation treatments, from cancer immunotherapies to synthetic proteins and mRNA vaccines.

“The potential for impact is immense,” said Tero-Pekka Alastalo, CEO of Avenue Biosciences. “With this platform, we are not only optimising the production process but enabling faster access to therapies that could significantly change patients’ lives.”

Tuomas Kosonen, Partner at Inventure, added, “Their innovative approach to a persistent bottleneck in protein production has the potential to disrupt the biopharmaceutical industry. We are especially excited to support Tero-Pekka for the second time as the team works towards realising the full potential of their technology.”

The company is poised to launch commercial sales of the platform in Q4, further fuelling the development of life-changing therapies. With operations based in Helsinki and a strategic headquarters in San Francisco, Avenue is positioned to tap into both Nordic expertise and North American markets, driving growth in the EU and beyond.
