The companies in Pontoise largely represent public services, education, and automotive sales. Among the larger entities, ESIEE-IT specializes in higher education, ESPERER 95 focuses on social inclusion, and GROUPE JALLU-BERTHIER operates numerous car dealerships. The municipality itself, Ville de Pontoise, is also a significant employer.
While there are established organizations like Saint Martin de France, founded in 1929, the list also includes more recent ventures such as VNB-IT, an IT services company established in 2022. This mix suggests a local economy that balances long-standing institutions with newer enterprises, particularly in sectors like education and automotive retail.

Turn this list into pipeline
Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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 12, 2026.
