The Sainou Team

David Marsden | Sainou Talent Agency London

David Marsden – Partner and Senior Agent

David trained and worked professionally as an actor for 18 years before becoming an agent in 2001 and creating a leading London agency.  In 2010 he became co-chair of the Artists’ PMA.  The PMA (Personal Managers’ Association) is the leading professional body for literary and theatrical agencies in the UK.  Between them they manage the careers of almost all the UK’s dramatists and screenwriters, actors, directors and creatives both in the UK and abroad.

When not securing work for his clients, David can be found trekking through jungles, climbing mountains or exploring the world’s most exciting cities in search of a great photo opportunity.


Paul Martin | Sainou Talent Agency London

Paul Martin – Partner and Senior Agent

Paul trained and worked professionally as an actor building a vast network of contacts and industry knowledge.  He worked at two West End agencies, becoming a company director at the second and heading up their Film & TV department.  With more than 10 years agenting experience he then went into partnership with David to set up Sainou. He also works closely with Equity on developing UK New Media deals for actors across the industry.

Paul is a huge Sunderland AFC supporter and can often be found celebrating (or more often commiserating) at the Stadium of Light.  He’s also a complete Historical geek. After agenting, these would be his subjects of choice on Mastermind.
