Diepenbeek, BioVille, Belgium, December 18, 2025 – SimAbs is proud to announce the successful closing of a €5 million Series A financing round. This investment marks a major step in the company’s growth strategy and reinforces SimAbs’ ambition to transform antibody and biosimilar manufacturing through Full end-to-end continuous processing.

The Series A round brings together a mix of existing and new investors, combining strategic industrial insight with long term financial backing, underscoring strong confidence in SimAbs’ proprietary continuous manufacturing platform and its potential to reshape global biologics production. Existing investors also increased their commitments.
