Sismic, Développement Logiciel

What Sismic, Développement Logiciel does

SISMIC (Sismic, Développement Logiciel) is a privately-held French custom software development firm founded in 2011 and headquartered in Lieusaint, Île-de-France. The company provides bespoke application development services for business clients, with a stated emphasis on becoming domain experts in client businesses rather than acting as generic coders. Its core service offerings include custom CRM development, intranet solutions, bespoke business software, corporate website development, database work, training, consulting, audit, and technology monitoring (veille).

The company builds its solutions using standard web technologies with a focus on three positioning pillars: sur-mesure (customization to fit client workflows rather than the reverse), multi-plateforme (cross-device accessibility), and evolutif (scalability over time). Its underlying technology stack is not publicly detailed beyond "web technologies," and no proprietary platform, product, API, or AI/ML component is offered. Deliverables are professional services engagements rather than packaged software products.

SISMIC operates on a project-based, quote-driven revenue model with no published pricing and no standardized tiers. Go-to-market is sales-led and direct, with prospects engaging via the company website (contact form, email, phone). Customer engagement is described as long-term and multi-year contractual, though no enterprise logos are publicly disclosed beyond two small case-study references. The company is bootstrapped and founder-led by Mikael Paris, with a small team of approximately 5-8 people including front-end, back-end, and project management roles.
