The Operating Partners

The operators. Bios that read like the work.

Each partner runs a portfolio function across every OneX engagement — not advisory titles, operating mandates.

Our In-House Entities

How we structure and deliver.

OneX Ventures operates through a network of in-house entities, each playing a specific role in how we structure and deliver engagements. These are not third-party vendors we procure from — they are established partners we have worked with directly across prior engagements, and they form the operational backbone through which engineers and operators are deployed into portfolio companies.

Holding & Orchestration

BeHuman Capital

Delaware, US.

The holding company through which OneX Ventures' equity positions and deal structures are formalised.

Talent Provider

Agile Catalyst

California, US — with offices in Dubai and Ahmedabad.

An in-house talent and engineering deployment partner — one of the firms through which the OneX operator network is mobilised and contracted onto engagements.

Talent Provider

Bia Technologies

California, US — distributed delivery across Europe, MENA, Australia, and the US.

A distributed delivery network with partners in Ahmedabad, Rajkot, Brisbane, Zagreb, Vilnius, Dubai, Paris, and Seattle — the second engine through which engineers are deployed into portfolio companies.
