Our history?

Founded in 2011 by CEO Clwyd Probert, Whitehat began its journey to becoming a leading SEO expert, HubSpot partner and London HUG leader.

Today, Whitehat proudly bears a team that encompasses the founder's passion for entrepreneurship, commitment, investment and helping others achieve business success.

Ingrained by the CEO, attributes of ‘always learning’ and ‘helping first’, are held dear.

Leading by example, Clwyd is a mentor to postgraduate students and teaches marketing, as a guest lecturer, at UCL.

He’s also a patron of Hope4Apes, The Battersea Cats and Dogs Home, and The Born Free Foundation. Plus has worked alongside Brian May, Sir David Attenborough, Ian Redmond, and Virginia McKenna.
