About Fincome

Fincome is an AI-powered Revenue Intelligence platform designed for software leaders. We transform fragmented billing data into real-time SaaS metrics and predictive insights so CEOs, CFOs, and CROs can drive growth with confidence. In just three years, over 200 software publishers, including LegalPlace, MailInBlack, HelloCSE, Octime, Infolegale, and Agorapulse, rely on Fincome daily. Our development extends beyond France and is entering a new phase: to become the reference platform for managing the revenues of mid-market and Enterprise SaaS companies.

Why this role is special

You will work directly with Axel, a serial entrepreneur and GTM leader, and be at the heart of how Fincome creates value for its clients. This is a unique opportunity to learn how top-performing SaaS companies transform data into retention, expansion, and strategic decisions, and how Customer Success becomes a true growth engine. Expect a steep learning curve, real ownership over a portfolio of strategic accounts, and a front-row seat to see how a SaaS company transitions from initial traction to category leadership.

Your mission

Drive Fincome client success, retention, and expansion, and transform our client base into our most powerful growth lever. As a key role within the Client Success Partner team, you will support our clients in their revenue intelligence strategy via the Fincome platform.

• Build lasting client relationships: create strong, multi-stakeholder alignment with CFOs, controllers, and C-level stakeholders.
• Lead structured performance reviews: conduct QBRs focused on measurable results (retention, expansion, forecast accuracy).

• Collaborate cross-functionally: share client insights with Product and GTM teams to strengthen positioning and roadmap.
• Maintain rigorous account hygiene: keep CRM, health scores, and action plans updated with discipline.
• Continuously improve processes: document best practices, optimize playbooks, and elevate the CSP execution level.
