Osapiens wants to use the fresh money to accelerate product innovation and drive growth in existing and new international markets. According to co-CEO Alberto Zamora, the startup’s goal is to “become the undisputed global leader in sustainable growth for companies of all sizes.”
That’s what Osapiens does
The founders Alberto Zamora, Stefan Wawrzinek and Matthias Jungblut built a platform in 2018 that companies can use to identify risks within their supply chain, implement reporting requirements and establish more sustainable processes such as shorter transport routes in the long term.
The company’s core product is the Osapiens Hub: an AI-powered, cloud-based platform that simplifies compliance with international ESG regulations. The tool covers reporting obligations such as the Corporate Sustainability Reporting Directive (CSRD) adopted by the EU, the EU regulation on the deforestation-free supply chain (EUDR) and the EU supply chain law, the Corporate Sustainability Due Diligence Directive (CSDDD) – according to the company, more than 25 solutions for companies. AI enriches customer data and automates processes.
