Manager (Consulting)

At 3HORIZONS, we’re reshaping what strategy means in the real world - not as a document, but as a force for impact. We are a global strategy consultancy trusted by leading organisations across industries: from multi-billion industrial powerhouses and pharmaceutical giants to cutting-edge manufacturers and even Super Bowl champions. Our mission is simple: help leadership teams close the gap between ambition and execution - faster, smarter, and more effectively than traditional consulting ever could.
The engine behind this transformation is the Strategy in Action System:

• Enterprise-grade software that turns strategy into live, structured workflows
• An AI intelligence engine that surfaces real-time insights, risks and opportunities
• Certified experts who bring pace, challenge and alignment into every leadership room

Founded in 2005 and headquartered in London, with offices in New York, Turin and Nicosia, we bring together strategy consultants, industry experts and product innovators to deliver strategy with clarity, momentum and measurable results.
We don’t just advise - we co-create strategy and build strategic capability inside organisations, empowering teams long after the engagement ends. 3HORIZONS has been certified as a Great Place to Work® for 3 consecutive years.
