osapiens Raises $100M, Cements Unicorn Status as Europe’s Sustainability Compliance King
osapiens, the Berlin-based sustainability software platform automating ESG reporting for Europe’s largest enterprises, has raised $100 million in a blockbuster round valuing the company at over $1 billion – marking Germany’s latest unicorn and Europe’s sustainability tech breakout star.
Founded in 2021 by serial entrepreneur Johannes Ahlsen, osapiens solves the nightmare of CSRD, EU Taxonomy, and LkSG compliance through AI-powered data aggregation that connects suppliers, operations, and finance systems into automated audit-ready reports. While corporates spend millions on consultants for Excel purgatory, osapiens delivers real-time carbon accounting, supply chain emissions mapping, and regulatory filings updated daily.
The platform serves 500+ DAX 40 companies and Fortune 500 multinationals drowning in 5,000+ page sustainability disclosures. osapiens’ secret sauce: pre-built connectors to SAP, Oracle, Salesforce, and 200+ ERPs, plus AI that classifies unstructured emissions data with 98% accuracy across 50 jurisdictions.
The capital fuels U.S. expansion targeting SEC climate disclosure rules and Asia-Pacific Taxonomy launches. osapiens plans to double its 300-person team while acquiring fragmented carbon accounting point solutions. Green bonds, ESG funds, and sovereign wealth money poured in, validating sustainability’s trillion-euro compliance wave.
osapiens proves Europe’s regulatory muscle births software empires. When DAX 40 CFOs sleep peacefully knowing AI handles their €50 million CSRD fine risk, $100 million becomes the tollbooth collecting sustainability’s digital dividends across corporate Europe. Compliance yesterday becomes competitive moat tomorrow.
