Once For All

Born from a merger of specialist UK and French compliance firms, Once For All unified under a single platform headquartered in Paris.

Backed by private equity firms GTCR and previously Warburg Pincus, the company has grown through strategic acquisitions.

It delivers a SaaS network matching contractors with vetted suppliers, leveraging AI to streamline tendering, compliance and ESG risk.

Typical projects involve large main contractors in Europe needing pre

qualified subcontractors for construction, facilities or utilities work.

Its platform supports complex workflows — from health & safety checks to legal document validation — across multiple national schemes.

Once For All stands out for managing one of the largest proprietary ESG and compliance datasets in the built environment.

Its reach spans the UK, France, Belgium, Germany and Italy, with pan

European capabilities in energy, building and property sectors.

A standout fact: it powers specialist schemes like Constructionline, Actradis, BidWork and RISQS under one umbrella.
