After spending time both agency and client-side at a range of digital businesses, I co-founded Stream:20 in 2005 which we grew to become a leading digital consulting business in the UK, USA and Europe with clients such as Sky, Experian, Microsoft and Fox.

Stream:20 was acquired by CACI UK in March 2016 and re-branded to CACI Digital Consulting in Jan 2017.

In 2021 I founded Wild Bull Capital, an investment firm focusing on Web 3.0 investments.
