Robertson, former account director at Speed, joins FieldHouse as senior associate, while Hudspith, former Speed account manager, joins as an associate.
Both specialise in mobile and technology and will look to grow the agency and enhance the client offering on the mobile side of the business.
Cordelia Meacher launched FieldHouse in April last year and has built a roster of clients in the venture and tech space, including EVRYTHNG, Blur Group and MMC Ventures.
Robertson previously worked alongside Meacher at IF Communications, which was subsequently sold to Hotwire.
Roberston commented: ‘Having known and worked closely with Cordelia for a number of years, I knew FieldHouse would naturally be a success. I also knew that if I was going to go into a start-up agency again, it would undoubtedly be with Cordelia, so it goes without saying that I am incredibly excited to be working with her once more.’
Meacher added: ‘I'm absolutely delighted to welcome Neil and Nicole to help me build the business, and in particular to focus on mobile. Both have significant knowledge and expertise, and are full of energy and drive, and I know that FieldHouse is on the cusp of explosive growth.’
