Meet Meridian: The Berlin Climate-Tech Unicorn You Need to Know About This Month

In a move that signals renewed confidence in Berlin's climate-tech corridor, Meridian—a four-year-old software platform addressing Scope 3 emissions tracking—announced its largest funding round yet on Monday, pulling in €185 million from a consortium led by Breakthrough Energy Ventures and local heavyweight Lakestar. The company, headquartered in a converted warehouse on Mehringdamm in Kreuzberg, is now valued at €1.2 billion, making it one of the few German climate-tech firms to reach unicorn status.

What sets Meridian apart in a crowded market is its focus on supply-chain transparency. While larger enterprises have invested billions in reducing direct emissions, tracking indirect emissions across complex global supply networks has remained notoriously difficult—and often delegated to spreadsheets. Meridian's API-first platform automates this process, integrating with existing procurement and ERP systems to give companies real-time visibility into their carbon footprint across thousands of suppliers.

The timing matters. Germany's supply-chain due diligence law, which took effect in 2023, requires mid-sized companies to audit environmental and social impacts throughout their operations. Enforcement tightens next year. Simultaneously, the EU's Corporate Sustainability Reporting Directive mandates detailed emissions disclosure for all large companies by 2025—a deadline that has triggered a scramble for solutions. Meridian claims it now serves over 2,400 corporate clients, from automotive suppliers in Baden-Württemberg to logistics firms in Hamburg.

The Berlin ecosystem deserves some credit here. While the city's venture scene fractured somewhat after the 2022 tech downturn—many VCs retreated or consolidated—specialist climate investors like Lakestar and the Technologie-Stiftung Berlin's advisory arm have remained committed to green innovation. Meridian's founders, who previously built data infrastructure at SoundCloud and Zalando, explicitly chose Kreuzberg over Munich or Frankfurt, citing access to engineering talent and proximity to other climate and mobility startups clustered around Görlitzer Straße and the Betahaus.

The €185 million round will fund product expansion—particularly in AI-assisted emissions forecasting—and regional scaling across the EU. The company plans to hire 120 engineers and product specialists over the next 18 months, mostly in Berlin, where office space on the former industrial estates near Ostkreuz remains cheaper than in Frankfurt or Munich.

For investors watching Germany's startup sector, Meridian represents a broader trend: deep-tech solutions addressing regulatory-driven market demand, not hype cycles. That distinction may prove decisive as venture capital becomes more selective in 2026.
