Who we are


When it was founded in 2001, EPSA was a consulting firm specializing in indirect purchasing and more specifically in the travel industry. Thanks to its numerous successes in purchasing optimization, EPSA has built a reputation in the operational performance support sector. This recognized expertise has enabled Matthieu Gufflet, founder of EPSA, to gain the trust of the largest entities of France’s Stock Exchange, the CAC 40, as well as the public sector, to continue expanding EPSA’s client base. Moreover, these exchanges with all types of companies have led to the expansion of EPSA’s offer to include new solutions for its customers. Our ambition is to become a key performance consulting firm, able to address all the issues that companies of all sizes may face.

Thus, our expertise has gradually diversified thanks to external growth and the integration of companies with specific areas of expertise: IT purchasing, Telecom, HR, IP, supply chain, marketing…


A few years later, in 2015, EPSA succeeded in diversifying its areas of expertise by integrating a BPO (Business Performance Outsourcing) offer, social cost optimization, change management and purchasing outsourcing via its own Marketplace. EPSA is now positioned, both in France and internationally, on all cost centers and expenses of a company and thus strengthens its ability to work on all optimization levers for its customers.
Through a few carefully chosen partnerships and buyouts (such as Experbuy, Enoptea, Saaswedo, Taas and ekodev, among others) EPSA has taken a huge step towards becoming one of France’s new generation of consulting players who seek to integrate digital solutions with their expert know-how to round out their support. This coupling between human expertise and the power of digital technology allows for the transformations necessary for the emergence of real productivity gains, making EPSA a creator and producer of sustainable performance, a true pioneer in the profession.

EPSA’s teams are resolutely customer-oriented and seek performance and efficiency on a daily basis with a “tailor-made” and sustainable approach, adapted to each need and specificity of your organization.

Today, EPSA is taking up a new challenge by including CSR solutions in each of its areas of expertise in order to always offer a solution that is adapted to the challenges of today while anticipating those of tomorrow.
