Sanofi's 'Internal Tinder' Filled 7,600 Roles and Ended 30,000 Late Payments

When Sanofi's HR team looked at how long it took to move someone into a new internal role, the answer was embarrassing — 7.8 days at the median, 33 days on average. For a company with nearly 100,000 employees across 90 countries, those delays meant 30,000 late payments every single month. Then they deployed Workday's AI Career Hub. Median processing time dropped 87%, from 7.8 days to one day. The platform has since filled 7,600 internal roles — and employees call it "internal Tinder" because it matches them to opportunities based on competencies, not credentials, without the usual biases around gender or background. But the part that's hardest to copy isn't the technology. It's the governance. Sanofi built a framework called RAISE — Responsible AI for Everyone — that made the system transparent and explainable enough that 80% of employees voluntarily opted in at launch. No mandate needed. Just trust. In this episode, we break down what Sanofi actually built, what drove the adoption, and what this case tells HR leaders evaluating AI for internal mobility.
