osapiens
What the business is
osapiens is a Mannheim, Germany enterprise SaaS company whose osapiens HUB platform automates sustainability reporting and regulatory compliance — ESG data, supply-chain due diligence, carbon accounting — for large companies.
Starting capital：US$27M Series A (2023, Armira Growth); US$120M Series B (2024, Goldman Sachs Alternatives); US$100M Series C (Jan 2026, Decarbonization Partners) — over US$247M in disclosed rounds.
How it started
osapiens was founded in 2018 in Mannheim by Alberto Zamora, Stefan Wawrzinek and Matthias Jungblut to solve 'full transparency across complex, global value chains'. The bet: as the EU and member states passed sustainability reporting and supply-chain due-diligence laws, enterprises would need software — not spreadsheets or consultants — to collect, verify and report non-financial data at scale.
What happened
After a US$27M Series A from Armira Growth (2023), osapiens closed a US$120M Series B led by Goldman Sachs Alternatives in July 2024; SiliconANGLE reported its installed base had more than quadrupled in a year to 1,300+ customers including Coca-Cola and Costco. It then expanded internationally (a $40M UK investment plan announced July 2025, new offices in Benelux and France), acquired Berlin-based agentic-AI risk management startup Lucent AI, and grew to 2,400+ customers and 550+ staff.
How it ended up
In January 2026 osapiens announced a US$100M Series C led by Decarbonization Partners, the BlackRock–Temasek joint venture, lifting its valuation above US$1B and making it the first German unicorn of 2026; TechCrunch listed it among Europe's five new unicorns of January 2026.
Background
osapiens was founded in 2018 in Mannheim, Germany by Alberto Zamora, Stefan Wawrzinek and Matthias Jungblut with a simple thesis: the wave of ESG and supply-chain regulation — Germany's LkSG, the EU's CSRD, and similar rules — would force enterprises to collect, verify and report non-financial data across global value chains, and they would buy software to do it.
The company built osapiens HUB, a multi-tenant, AI-powered SaaS platform with 25+ solutions: transparency modules that map and monitor suppliers and emissions, reporting modules for sustainability frameworks, and efficiency modules for asset and field-service operations. Growth tracked the regulatory calendar: a US$27M Series A from Armira Growth in 2023, then a US$120M Series B led by Goldman Sachs Alternatives in July 2024, when SiliconANGLE reported the installed base had more than quadrupled in a year to 1,300+ customers including Coca-Cola and Costco.
By January 2026 osapiens counted 2,400+ customers — Coca-Cola North America, Lidl, Tesco, BAT, Carrefour, OTTO and more — and 550+ staff across Europe and the US, having added a $40M UK expansion plan, offices in Benelux and France, and the acquisition of Berlin-based agentic-AI risk management startup Lucent AI. A US$100M Series C led by Decarbonization Partners (the BlackRock–Temasek joint venture) lifted the valuation above US$1B, making osapiens the first German unicorn of 2026 and one of Europe's five new unicorns that month.
What has to be true
- ESG rules made compliance a legal requirement with deadlines, so demand arrived on a schedule instead of needing to be created.
- Regulatory complexity across countries (LkSG, CSRD, EUDR, UK frameworks) favored a platform over point tools or consultants.
- The multi-tenant, AI-powered HUB handled supplier questionnaires, emissions data and reporting in one place, locking in large enterprise accounts.
- Each new regulation became a new module and sales motion, compounding the wedge into a category.
- BlackRock–Temasek's Decarbonization Partners, Goldman Sachs and Armira Growth gave it the capital to scale internationally before rivals caught up.
What can be applied
Regulation can be a growth wedge if you productize the mandate: each new law (LkSG, CSRD, EUDR) became a module and a sales motion, compounding one compliance niche into a platform.
Aftermath
As of 2026-01-31, osapiens was a >$1B-valuation unicorn with 2,400+ customers and 550+ staff. Series C proceeds were earmarked for product innovation and international expansion, following its Lucent AI acquisition and $40M UK investment plan, with the stated goal of becoming the global category leader in enterprise software for sustainable growth.
