Tamtam tracks 141 SaaS companies headquartered in the Gironde department. This list ranks the 30 largest by number of employees on LinkedIn, led by Apotik, Maincare and AT Internet, a Piano company. Their median headcount is 60. Half of them were founded in 2013 or later. The most common headquarters are Bordeaux (15), Mérignac (3) and Pessac (3).

These SaaS companies in Gironde primarily focus on software development and IT services, with a notable presence of firms established in the last two decades. Companies such as Maincare, founded in 1999, develop software solutions for French healthcare institutions, while IRIUM SOFTWARE, established in 1982, specializes in management software for equipment dealers. Newer entrants like Apotik (2021) streamline pharmaceutical business management, and Haiku (2023) applies AI to legal practice.

A significant concentration of these companies, including Octopia, HelloAsso, Synapse Medicine, and Immersion, are headquartered in Bordeaux.

## 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 11, 2026.
