Portfolio Control
Portfolio Control GmbH was established in 2003 by former investment bankers Claus Lemke and Jörg Flechtner. The firm operates from Starnberg and provides services to entrepreneurial families, foundations and professional sports organizations. The firm combines asset allocation, private-market investments and corporate-finance advisory. It executes direct co-investments, fund-of-funds commitments and distressed transactions across Europe and North America. Confirmed relationships include advisory work for M Objekt Real Estate Holding GmbH & Co. KG on bond issuances and a decade-long advisory-board role at 1. FC Nürnberg by Flechtner from 2007 to 2017. Portfolio Control also maintains a sister entity, Portfolio Financial Services GmbH, currently in liquidation. The firm lists memberships in the Family Office Club and the Premium Leaders Club, where Flechtner serves on the advisory board. No headcount or AUM figures appear in public materials. The website records an IPO mandate for BENO Holding AG and an M&A transaction for FB-Yachtcharter without disclosed dates. Portfolio Control integrates operating-company oversight directly into wealth reporting, a structure that distinguishes it from pure investment offices. This approach requires ongoing coordination between financing structures and portfolio risk monitoring.
