# The 27 largest Financial Services companies in the Bouches-du-Rhône department

Tamtam tracks 27 Financial Services companies headquartered in the Bouches-du-Rhône department. This list ranks all of them by number of employees on LinkedIn, led by MONEXT, Initiative Ouest Provence and EXPANSI Avocats & Experts-Comptables. Their median headcount is 17. Half of them were founded in 2014 or later. The most common headquarters are Marseille (12), Aix-en-Provence (10) and Aubagne (2).

This selection of financial services companies in Bouches-du-Rhône includes a mix of established firms and younger ventures, focusing on payments, accounting, audit, and financial advisory. MONEXT, founded in 2008, is a major player in payments in France and Europe. EXPANSI Avocats & Experts-Comptables, from 2017, offers comprehensive accounting and legal services, while Piana, founded in 2022, provides innovative payment solutions for modern fleets. WeCashUp, established in 2015, offers a virtual supermarket for Mobile Money agents in Africa.

A notable pattern is the concentration of headquarters in Aix-en-Provence and Marseille, with several companies like MONEXT, EXPANSI, ACE Audit et Conseil des Entreprises, and Groupe Altéor based in Aix-en-Provence, and Piana, Collaboration Capital, WeCashUp, and MORTIER & Associés located in Marseille. This indicates a clustering of financial expertise in these two urban centers within the department.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 15, 2026.
