Cas Paton has left his role as MD of British online marketplace OnBuy.
Paton set up OnBuy early last year with Simon Lennon in a bid to rival bigger sites like Amazon and eBay, and secured major investment from IT provider Centerprise International.
However, Paton's Linkedin profile shows that he stopped working for his company OnTop Media in March.
He confirmed to PCR that he is 'no longer a part of OnBuy', but said he couldn't add anything else.
Centerprise declined to comment.
It's not clear whether a new OnBuy MD is being recruited or what the plans are for the online marketplace going forwards.
