Lee Adams

Lee Adams is CEO and Co-Founder of Cantarus, a digital agency specializing in creating digital experiences for membership organizations, associations, and purpose-led brands. 

With over 25 years of experience in digital, Lee works with CEOs and senior leadership teams to navigate complex transformation — helping organizations respond to shifting expectations around member value, engagement, and long-term sustainability. 

He is a strong advocate for a more joined-up approach to digital — bringing together platforms, data, and experience to move organizations beyond siloed systems towards more connected, insight-led operating models. 

Under his leadership, Cantarus has grown sustainably over two decades — building a strong reputation within the UK membership sector and more recently expanding into the US, applying a proven approach to support membership organizations internationally.

Cantarus was the first Umbraco partner to achieve platinum status in both the UK and US.

Lee has worked with a range of leading membership bodies including the Royal Institute of British Architects (RIBA), the Chartered Institute of Procurement and Supply (CIPS), the British Computer Society (BCS), and the Chartered Institute of Marketing (CIM), supporting them to modernize their digital foundations, strengthen engagement, and make more confident strategic decisions.
