osapiens is building the operating system for sustainable enterprise, a single AI-powered platform giving every company real-time control over regulatory obligations, climate impact, supply-chain risks, and physical assets. The ambition is not to be one more compliance tool, but the infrastructure every global enterprise runs on to operate responsibly in a world where sustainability is no longer optional.
We reached unicorn status in January 2026 ($100M Series C from BlackRock/Temasek and Goldman Sachs), serve 2,500+ enterprise customers including Tesco, Coca-Cola, Lidl, and Carrefour, and have delivered 10+ consecutive quarters of 100%+ ARR growth at 130%+ net revenue retention. Four platform capabilities: Regulatory Compliance, Climate Intelligence, Supply Chain Transparency, and Asset Management, plus a network model that traces supply chains from origin to point of sale make the platform genuinely different. Not another point solution. The resilience control tower for the modern enterprise.
The (Senior) Customer Success Manager owns osapiens' most strategic customers. High-value and high-profile accounts that demand a senior, consultative relationship, close monitoring, and proactive engagement. After the sale, you become the customer's trusted advisor, responsible for retention, adoption, and growth across your portfolio. You coordinate internal stakeholders around the customer's success and ensure each account realizes the full value of its investment.

Substance, not slogans
2,500+ customers on the platform. BlackRock, Goldman Sachs, and Armira as investors. A product that won the European market without a heavy sales machine. None of this is hypothetical — it is what the role is built on.
Real ownership
You shape your book of accounts, your topic lane, and the success-plan logic. Your account signal feeds product, pricing, and GTM — not as a token gesture, as the actual mechanism.
AI-native team
Real budget for AI tooling and a mandate to set the frontier on AI-augmented enterprise CS. We don’t bolt AI on; AI is how the team operates.
Senior leadership access
A structured CS organisation with senior leadership support, an Academy team for customer enablement, and Professional Services that own onboarding cleanly.
The practical bits
- Competitive base salary plus a CS performance component tied to retention, expansion, and adoption KPIs.
- Hybrid working out of Munich or Madrid — strong in-office presence (3 days per week), and regular time on-site with customers across Europe.
- Career path into CS Team Lead, CS strategy, or strategic account roles in the broader commercial organisation.
