A Team of Builders, Operators & Investors

Stonebridge was founded in 2016 by James Cox, a serial entrepreneur who has founded and exited three market-leading consumer technology companies for a combined nine-figure sum. Among these is Simba Sleep, which scaled to over $150m in profitable annual revenue. Over the past decade, James has also led more than $500m in direct investments into high-growth private companies.

​

The operational team is led by Ryan Thorne, previously in-house counsel at BlackRock and an M&A lawyer at Freshfields Bruckhaus Deringer.

​

Stonebridge is backed by a powerhouse network of Europe’s top entrepreneurs, including founders of technology and consumer giants, managing partners of leading private equity and hedge funds, and prominent personalities from sports and entertainment. Collectively, they've created over $75bn in shareholder value and have a combined social media following of over 15 million, contributing not just capital, but also strategic connections, deep operational expertise, and significant influence.

 

By combining decades of operational experience, strategic insight, and elite global networks, Stonebridge provides unmatched access and accelerates transformative growth for its portfolio companies.
