Company overview
Founded in 2011, Vertical Sea’s focus is on engineering, consulting and project management at the heart of the energy and environmental transition. Its expertise encompasses all services bridging the space between project owners and contractors in the fields of energy, geotechnics, hydrogeology, polluted sites and soils, etc.
Our approach
With the support of Weinberg Capital Partners, Vertical Sea is now able to continue its structuring programme to better absorb expected growth, accelerate its consolidation plans and thus increase its market share to further strengthen its core business. Thanks to this support, the group aims to move into new verticals, new customer segments and new geographies.

Making a difference
For a number of years, Vertical Sea has contributed to sustainable socio-economic development at the local level through its support for several organizations: Baroudeurs de l’Espoir, which helps victims of armed conflicts and other violent situations; Architectes Solidaires, which works to improve rest areas used by healthcare workers; and Les Papillons du Jour, a communications agency at which 80% of staff members are people with disabilities.
