Local advertising platform modernizing legacy systems for regional media

Advertising Services RENNES 501–1,000 employees Privately Held

Additi operates a regional advertising and local media business with a PHP + Symfony + PostgreSQL stack running on GitLab CI/CD, selling through Salesforce. The hiring mix is heavily sales-focused (8 of 12 active roles), yet the project backlog — modernizing legacy systems, building APIs for niche sectors (funeral industry noted), and qualifying prospect databases — reveals an engineering transformation underway. This split signals a company extending legacy ad-buying platforms into new verticals while simultaneously derisking technical debt.
