Stonebridge is the family office and private investment firm of entrepreneur and investor James Cox.


Founded in 2016, the firm demonstrates a strong track record in originating, investing, acquiring, and exiting disruptors spanning multiple industries. Our adaptive investment approach remains impartial to sector, stage, and geography, favouring equity or equity-linked direct investments that yield the potential for augmented and uncorrelated returns.

Emphasising long-term value creation, Stonebridge implements a diligent investment strategy, allocating our permanent capital alongside a chosen cohort of like-minded investment partners, with whom we maintain durable, trust-based relationships.

With our hands-on experience of founding, scaling and exiting our own companies, we offer insight and empathy, remaining resolute in our determination to supply the necessary time and support to assist our portfolio companies in navigating the path to success.
