What CROISSANCE CLIENTS does
CROISSANCE CLIENTS (operating as Croissance Clients SARL) is a French marketing, sales, and communication consulting firm headquartered in Armentières, in the Hauts-de-France region near Lille. Founded in 2020 by Guillaume HERON — a consultant with 25 years of experience — the firm targets very small businesses and SMEs (TPE/PME) primarily in the Nord and Pas-de-Calais departments. The service offering is structured around three engagement formats: a part-time executive model ("cadre à temps partagé") that embeds a senior commercial/marketing operator inside client organizations, multi-month projects, and short-term missions, giving clients flexible access to senior commercial expertise that they could not justify on a full-time basis.
The firm operates as a single-member LLC (SARL à associé unique) with €5,000 of share capital and a core team of two to ten people, supplemented by a network of external experts. No proprietary technology platform, software product, or AI-enabled tooling is disclosed; delivery is human-consulting based, and the corporate website functions as the primary marketing channel rather than a product surface. There is no disclosure of funding rounds, external investors, partnerships, M&A activity, or revenue figures.
Revenue mechanics are project-based and fee-for-service across the three engagement models, with no recurring subscription or platform component. The geographic footprint is explicitly regional — Hauts-de-France — and the customer profile is the long tail of small French businesses. The business is bootstrapped at formation capital levels and is structured as a lifestyle/expert-consulting practice rather than a venture-scale asset.
