Greece

Message

At Simpler. Checkout, I manage relationships with 450+ B2B SaaS clients across six EMEA business units. I connect business development, product, and engineering teams, translating product capabilities into business outcomes.

I monitor in-house and third-party integrations and use usage patterns and risk signals to proactively mitigate churn. I also support cross-selling and up-selling buyer incentives and partner services.

At Endeavor Greece, I launched initiatives to increase founder engagement and created people programmes with the global team for offices in 39 countries. I also managed financial operations and relationships with board members, VCs, and entrepreneurs.

Earlier, I oversaw budgets, grants, and financial reporting at ReGeneration, and managed customer care representatives at AirFastTickets. I also co-founded Appe Studios, where I managed client relationships from initial scoping through delivery and post-launch support.
