About Erik Massmann
Dr. Erik Massmann is a finance executive with more than 30 years of experience, including more than 20 years as a chief financial officer. He holds a diploma and a doctorate in economics and political science from Freie Universität Berlin. He began his career in corporate finance at DG Bank.
He became CFO of the software company IBS AG in 2001. He then joined CompuGroup Medical in 2003 and served as its CFO until 2009, and he led its 2007 IPO process. He worked at Personal & Informatik AG until 2010. He was CFO of Sportradar AG, a sports technology company, from February 2014 to September 2019. Later roles included CFO of the online fashion brand Oceans Apart from 2020 and CFO of Wunschgutschein GmbH.
He joined Birkenstock in November 2022 and became Group CFO on 28 February 2023. He stepped down at the end of January 2025. He has been a member of the supervisory board of innoscripta SE since November 2024, and MarketScreener lists him as chair of the supervisory board of Sciil AG.
The public record of his angel activity is thin. The one round we could confirm is his participation in Kazimi's pre-seed in August 2026, where press coverage describes him as an angel investor. Fundable lists one angel investment for him, also Kazimi. Crunchbase lists a director role at ENAAA Ventures from July 2009 but shows no investments. We found no disclosed check sizes.
Kazimi raised an oversubscribed €2.2M pre-seed in August 2026. Market One Capital led the round, with IBB Ventures, Petri Hyökyranta, Janne Peltola and Massmann also taking part. Kazimi is a Berlin-based mobile security company that uses privacy-preserving cryptographic proofs to help app developers verify first-party data and separate real users from bots. The company was founded in 2024. Press coverage of the round does not describe Kazimi as an AI company, so founders should treat the AI link as indirect.
Massmann commented on the round. He called the bot problem in mobile marketing the elephant in the room. He said that knowing what is real matters for using AI effectively and for cutting out fraud.
The only confirmed investment is a pre-seed round in mobile security and data integrity software. Fundable tags his activity as Cyber Security and Software, based in Germany. He has not publicly stated a stage or sector mandate, and no check size is public. His operating background is in finance, HR, investor relations and IPO readiness at software, healthcare IT, sports data and consumer companies.
