MISSION
At Optimy, we believe that corporations can—and should—be a force for good.
Our SaaS platform enables global companies to manage and measure their social impact through grants, volunteering, donations, and sponsorships.
More than 350 organizations in over 30 countries—including Airbus, AXA, Roche, Michelin, Diageo, and Air France—rely on Optimy to power high-impact programs aligned with their values.
With over 1.5 million projects managed and a 93% customer retention rate, Optimy is a recognized leader in the social impact tech space. As we continue to expand in German Speaking Europe, we’re looking for a Belgium-based Account Manager to drive growth within our existing customer base.
What you’ll do
As an Account Manager focused on expansion, your role is to grow revenue from an existing portfolio of high-potential clients across Europe. You will not be responsible for renewals or day-to-day support—these are handled by our dedicated Renewals, support and Implementation teams.
Your core mission is to identify, qualify, and close upsell and cross-sell opportunities, helping our customers unlock new value from the Optimy platform. You will own the full commercial cycle of expansion deals, including discovery, demo, negotiation, and closing.
