What To Interface does

To Interface is a Dutch management and advisory consultancy founded in 2006 and headquartered in Vianen, Utrecht. The firm delivers professional services for complex projects in energy, water, construction, and infrastructure, with a service portfolio spanning EMVI-management and tender coordination, tender management, contract management (including NEC4 expertise), project management, omgevingsmanagement (environmental and stakeholder management), procesmanagement, and strategic procurement advisory. It operates as a horizontal network organization, complementing its core staff of roughly 36 professionals with formal partnerships across Connected Worlds (digitalization), Delteau (nature and water advisory, with cross-deployed staff under 'team Delteau'), Tornak (training and coaching), Clairfort (legal), and Tender2gether.

The firm works primarily with Dutch contractors and public-sector clients on large infrastructure and spatial-development programs. Named engagements include Shell Holland Hydrogen I (200MW green hydrogen plant), TenneT offshore grid connections (Net op Zee Hollandse Kust Noord), ProRail railway projects, Rijkswaterstaat infrastructure programs, Schiphol runway expansion, the PPS Gerechtsgebouw Breda DBFMO (33-year concession), the 12,000-home Waalsprong development in Nijmegen, and the 10-year, 5,700-home Thius housing renovation program. Revenue is generated through project-based professional service fees on a quote-based pricing model; no public pricing or revenue figures are disclosed.

To Interface's go-to-market is enterprise field sales driven by direct engagement with contractors, government clients, and consortium partners, leveraging long-term relationships and repeat engagements. Notable proprietary assets include the EMVI-procesplaat (a visual tender-process diagram) and Best Value Approach methodology, with the firm winning the European Bauhaus Award for Small Municipalities (NEB) in 2026 for the Kindcentrum Albertine Agnes project. The firm has also begun experimenting with hardware productization through the internally developed Lichtmast Sensor Unit for smart-city applications.
