GSG Asset Management

What GSG Asset Management does

GSG Asset Management GmbH is a Berlin-based commercial real estate services firm operating as a wholly-owned subsidiary of GSG Berlin GmbH, one of the largest commercial landlords in Berlin. The company manages the rental, asset management, and marketing functions for approximately 50 commercial courtyards (Gewerbehöfe) spanning roughly one million square meters of commercial space in Berlin. Its core offerings include lease origination and tenant contract management, portfolio optimization (including new-construction planning input on layout, fit-out, and target tenant identification), property repositioning and renovation advisory, and cost optimization across the GSG Berlin estate.

The firm operates a sales-led go-to-market built around direct leasing, with a supplementary broker-network distribution channel for mid-market placements. It serves a tenant base spanning individual merchants and tradespeople, craft businesses (Handwerksbetrieb), startups, and large publicly listed corporations (börsennotierte Großkonzerne), and runs an integrated marketing function that combines an online property search tool, SEO, social media (LinkedIn, Facebook, Instagram, YouTube, XING), events, and PR. Tenant satisfaction surveys are cited as the company's primary success metric, alongside the continuous value enhancement of managed properties. Leadership comprises Managing Directors Oliver Schlink and Sebastian Blecke, with René Richter as Head of Asset Management & Leasing and Michael Mandla as Head of Marketing, Communication & Innovation.

The business model is a managed-services arrangement under which GSG Asset Management provides asset and rental management to its parent on a fee basis, with revenue flowing from GSG Berlin and indirectly from third-party tenants leasing space within the parent portfolio. The firm holds no subsidiaries, has no disclosed funding rounds or external investors, and operates exclusively in the Berlin metropolitan market. Technology is non-proprietary and limited to standard marketing and property-search functions.
