Amsterdam-based Siilo’s secure medical messaging app seals $10.5 million Series A


Amsterdam-based medical messaging app Siilo has raised $10.5 million to expand across Europe, specifically in the DACH and Benelux regions as well as the UK and Ireland. The lead investor in the round is European digital health VC Heal Capital, which is backed by Germany’s private health insurers, and this marks the Berlin-based fund’s first investment since its launch a few months ago. Philips Health Technology Venture Fund and EQT Ventures also participated in the round.

The Dutch platform allows healthcare workers to communicate, share knowledge and research cases, all while sticking to regulations such as GDPR, ISO-27001, HIPAA and the NHS standards. 

Former surgery resident Joost Bruggeman (CEO) and Arvind Rao (CFO) founded the startup in 2016, after experiencing how outdated methods of communication — such as fax, pagers, and landlines — did little to help the already fragmented healthcare system. Now the Dutch app has over 250,000 users in healthcare institutions around Europe, such as Erasmus Medical Centre Rotterdam, Berlin-based Charité, and East Lancashire Hospitals NHS Trust.

“We believe there is a massive opportunity for healthcare to operate as a collaborative network,” says Bruggeman. “With Siilo, frontline care workers, public health officials, and everyone in between are able to practice medicine together.”

Dr. Christian Weiss, general partner at Heal Capital, believes the app could be “a true game changer in digitising the healthcare sector.”
