Sainou means talent and that’s what we’re all about.  Based in the heart of Shoreditch, Sainou represent a select list of actors & creatives including industry award winners, household names and some of the finest young, emerging talent.

Clients are represented by agents David Marsden, Paul Martin & Hermione Halpin with assistance from Dominique Munday and Kristian Wall.

Sainou are members of the Personal Managers’ Association.




Partner and Senior Talent 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.




Partner and Senior Talent 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.

Hermione trained at the Arts University Bournemouth and worked professionally as an actor, actively creating and producing her own work as well as theatre reviewing. Several years of experience assisting for a leading casting office – and in a busy central London casting studio – spurred a passion for management, turning her focus and capabilities fully to this side and joining Sainou in 2017.

Hermione can often be found with a notepad of ideas, plugged into an iPod, waiting for delayed trains in London or throwing herself off them in India.






Katie grew up in Kent knowing from an early age she wanted to become a bookkeeper after showing an interest in her dads books when he was self-employed. Her background was originally within the construction industry and after spending nearly 9 years with a sports construction company she decided the time was right to start her own company, KSM Bookkeeping Ltd. She provides bookkeeping and payroll services for a variety of small businesses and has studied bookkeeping and accounts over the past 10 years, proving her abilities by becoming a registered bookkeeper with the IAB.

Katie has a passion for photography and an enthusiasm for fundraising, and is always encouraging those around her to find new fun ways of raising money for various charities.
