Zimmerman takes up the post on 6th September, with Robinson stepping down after ten years at the online retailer.
The new MD boasts over eleven years of experience in the ecommerce industry, including a four year stint launching and heading up the music business unit at Amazon.co.uk before his most recent role as head of business development at Play.com.
Outgoing MD, Christian Robinson, said: "I have thoroughly enjoyed the past 10 years helping build the Firebox.com business and feel very lucky to have had the privilege of working alongside such a talented team. I am confident that now is the right time to appoint a successor to help lead our business through its next phase of growth and am delighted that Paul has accepted our offer to join the company as our new MD. Paul is the perfect fit for us and his wealth of experience within e-commerce will be invaluable to Firebox.com and help accelerate our growth even further."
Firebox recently celebrated record turnover and profits for the financial year ending 31st January, 2010 – £12.7m sales revenue and £1m profit before tax - and in June this year experienced its largest year-on-year turnover increase outside of Christmas in the retailer’s history.
Commenting on his new role, Zimmerman added: “I have been a customer and a huge fan of Firebox for many years – it’s such a fun, dynamic brand that is truly passionate about its customers. I am looking forward to working with the Firebox team and developing the brand as it continues to thrive.”
Michael Acton Smith, co-founder and chairman of Firebox, said: "Christian has been much more than a colleague over the years – he's effectively been the third founder of Firebox and also a great friend to Tom and myself. His role will not be an easy one to fill, yet I believe Paul’s experience at two of the UK’s largest and most well known online retailers will be a fantastic asset to Firebox. These are exciting times for Firebox and I'm really looking forward to working with Paul and the team to begin the next chapter of our growth story.”
