Walsh was most recently associate director at Waggener Edstrom and has worked as an independent consultant since leaving Wag Ed in April. He has previously worked across numerous UK tech PR agencies, including Nelson Bostock, Inferno, Marlin PR and Brands2Life.
Alan Soucy, Sparkpr CEO, commented: ‘We continue to be bullish across all our locations but London is becoming an increasingly interesting market for us – it has world-class universities, attracts significant investment, has a thriving technology scene and serves as a hub for the wider European market.
‘The London office will be key to extending reach for our clients as well as winning business from European start-ups and brands with global aspirations.’
The San Francisco-based agency has offices in Los Angeles, London, New York and Cape Town.
The agency’s UK client list includes BrightEdge, Etsy, Moo.com, ShowCaster, Torch Partners, Vidyo and YapStone.
Walsh added: ‘As well as having a highly credible position right at the epicentre of the global technology industry, Sparkpr has intimate relationships with many of the world’s most successful venture capitalists. Clients benefit from deep technology expertise while staff get to work with the most disruptive businesses in the industry.’
