TeamSystem, a leading technology and AI company specializing in business management platforms for SMEs and professionals, announced the acquisition of Sellsy, a top French provider of all-in-one CRM and financial management solutions. This acquisition strengthens TeamSystem’s footprint in France-following its recent acquisition of Clémentine-and marks another key milestone in its international growth strategy, with a strong focus on the Iberian market.
Founded in 2009 and headquartered in La Rochelle, Sellsy is recognized as one of France’s leading Lead-to-Cash solution providers for SMEs. Its comprehensive cloud-based platform integrates CRM, e-invoicing, pre-accounting, cash flow management, and marketing automation, all enhanced by advanced AI capabilities. The company plays a pivotal role in France’s upcoming mandatory e-invoicing reform (effective 2026), having secured official registration as a certified platform under review by the tax administration.
With more than 23,000 clients and over 180 employees-including 78 dedicated to product development and R&D—Sellsy’s strong innovation focus aligns seamlessly with TeamSystem’s vision. The company also has a presence in Spain through subsidiaries such as Quipu, further strengthening TeamSystem’s Lead-to-Cash offering across Europe.
Strengthening Europe’s SME Digital Transformation
The acquisition underscores TeamSystem’s ambition to establish itself as a technology leader for SME digital transformation across Europe and the Mediterranean. Sellsy’s platform, designed with micro and small businesses in mind, complements TeamSystem’s mission to deliver more than just software. Together, the companies aim to provide an intelligent, end-to-end platform that simplifies processes, accelerates growth, and creates measurable value for SMEs.

PSG Equity, a growth equity firm specializing in software and technology-enabled services, will exit its investment through the PSG Europe I Fund. Sellsy’s existing management team will remain in place to continue leading the business within the TeamSystem group, which has been backed by Hellman & Friedman since 2016.
Leadership Commentary
“Welcoming Sellsy into our group represents another step forward in our international growth journey, which we have been pursuing with determination for some time. Its technologically advanced solutions, natively equipped with AI functionalities, are aligned with our vision: to offer intelligent, comprehensive digital platforms that go beyond software, designed to provide concrete support to micro and small businesses,” Federico Leproux, CEO of TeamSystem, commented. “This acquisition confirms our commitment to building a strong and connected European ecosystem, capable of supporting professionals and businesses in their digital transformation, simplifying daily operations, and generating new value,” he added.
“With PSG’s support, we believe Sellsy has embarked on a truly transformative journey, combining strong organic growth with targeted M&A to become a leading provider of business management solutions for SMEs in France and Spain. Today, we are excited to continue this journey within the TeamSystem ecosystem, as we aim to pursue our shared ambition of building the leading European platform for SME management software,” Victor Douek, CEO of Sellsy, said.
“PSG Equity is pleased to have partnered with co-founders Alain Mevellec and Frédéric Coulais, supporting Sellsy in its growth journey. The results achieved reflect the vision of Victor Douek and his team in developing a lead-to-cash platform that provides strong support to European SMEs.
