Cerenion

Cerenion is a Finnish medical-device company developing AI-assisted monitoring of brain activity for acute healthcare. Its C-Trend EEG Station combines a disposable electrode array, EEG amplifier and quantitative analysis software to record brain electrical activity and display continuous trends for clinicians. The software measures slow-wave activity, burst suppression, amplitude-integrated EEG and alpha-delta ratios, helping intensive-care teams review changes in brain function alongside the original EEG recordings. The system is designed to make continuous EEG monitoring accessible to doctors and nurses who are not EEG specialists; the software does not itself provide diagnostic conclusions.

Butterfly Ventures’ own transparency table assigns Cerenion Oy to BVF III, with an initial investment in 2018: https://butterfly.vc/transparency-disclosure/butterfly-ventures-investee-companies/ . Icebreaker’s September 16, 2019 publication confirms a January 2018 co-investment with Butterfly: https://medium.com/icebreakervc/cerenion-raises-2-million-from-springvest-d94925e040b7 . The exact announcement day and amount of the first round remain unknown. Butterfly’s own company card separately confirms participation in the EUR 2 million pre-A round in Q3 2019: https://butterfly.vc/team/member/ville-heikkinen/ . A specific fund allocation for that follow-on is unconfirmed. Cerenion announced a completed EUR 4.359 million share issue on May 28, 2026, organized with Springvest, without naming Butterfly as a subscriber. Springvest’s portal displays EUR 4.353 million and a subscription end date of May 27; the final issuer-announced amount is retained. Springvest’s organizer role and later 5.2% holding do not establish a cash ticket in this issue.
