About Martin Berr-Sorokin
Martin Berr-Sorokin is based in Munich. He started his career in procurement at Siemens Energy, where he worked from 1993 to 2000, according to a professional directory profile.
He was CEO and co-founder of Xcitec from 2000 to 2011. He then held executive roles at Emptoris, as Senior Vice President and General Manager, and at IBM, as Director Product Line. IBM acquired Emptoris. He has also been a member of the supervisory board of objective partner AG since 2010.
In 2016 he co-founded IntegrityNext, a supply chain sustainability and compliance software company, and served as its CEO until January 2026. He is now Chairman of its Advisory Board. In 2023, EQT Growth announced a €100 million investment in IntegrityNext. Munich Startup reported that the co-founders had built the company through bootstrapping since 2016.
The one angel investment we could confirm is his participation in Elevatry's pre-seed round in October 2026. Elevatry's announcement lists him among several business angels. We found no public list of his other angel investments, and he has not published a check size or a fund.
Elevatry GmbH closed a €3 million pre-seed round on 15 October 2026. Bayern Kapital, the management consultancy H&Z and several business angels joined the round. Besides Martin, the angels named were Jan Henner-Theißen, Mike Simon, Markus Ehrle, Andreas Junck and Alexander Bruehl.
Elevatry builds an agentic AI platform for strategic procurement. It went live on 28 September 2026. Its AI "Companions" handle analytical work along the source-to-contract process. The company was founded in 2026 by Heiko Schwarz, Christian Ruck and Tizian Ruck and is based near Munich. It plans to use the funding to expand the platform, add Companions, and hire in engineering, AI, marketing and customer success.
The public record is thin, so this is limited to what we can see. His one confirmed AI round is a pre-seed in B2B procurement software in Germany. That fits roughly 30 years of work in procurement and supply chain software. He has not publicly stated a thesis, preferred stage or check size.
