Epsor operates a B2B SaaS platform for corporate employee savings plans (PEE), collective retirement (PER Collectif), and shareholder participation schemes across France. The tech stack reveals a finance-operations-first architecture: Excel and VBA sit alongside modern data infrastructure (BigQuery, dbt, Fivetran, Metabase), suggesting the company is mid-transformation from manual spreadsheet workflows toward automated, data-driven portfolio and investment tracking. Hiring is concentrated in finance and operations roles, with concurrent investment in mobile and lead-qualification automation—indicating a dual push to modernize customer acquisition and improve the investor experience.
