What ekoconcept does

Ekoconcept is a French construction economics and project management consultancy ("Bureau d'études d'économie de la construction") that provides cost estimation, technico-economic feasibility studies, tender analysis, and economic monitoring services for building projects across all construction trades (Tous Corps d'État). The firm operates as a subsidiary of VIATEC ECO, which was acquired by the PRESENTS group in 2023 alongside sister entities ARPENTIS (topography) and STRATERA (structural engineering). Together the group claims 5 entities and 20 local offices across France, though Ekoconcept itself maintains four agency locations (Lognes HQ, Paris, Montpellier, Cogolin) serving public sector clients (regions, municipalities, hospitals) and private developers, hotel operators, and social housing providers.

The company's underlying technology is human-delivered professional expertise rather than a software platform; there is no disclosed API, SDK, integrations, or AI/ML capability. Service delivery relies on direct engagement with project owners across pre-studies, design-phase economics, competitive tender support, and construction monitoring. Pricing is negotiated per-project, undisclosed, with multi-year contract cadences typical of construction professional services. Leadership comprises Pierrick Drnovsek as President and Kéovithoun Kéomykhom as head of the economics division.

The go-to-market is relationship-based sales-led B2B, responding to public tenders and participating in architecture/engineering competitions (concours de maîtrise d'œuvre) as economics partner to architectural firms. Revenue is generated through project-based professional services fees, with no standard rate cards publicly available and no disclosed revenue figures. Customer logos span BNP Paribas Immobilier, CEETRUS France, Hôpitaux Universitaires Henri Mondor, Région Île-de-France, SA HLM La Cité Jardin, and Royal Palace Kirrwiller, indicating project-by-project diversification across healthcare, education, hospitality, retail, and residential sectors.
