Rosa’s, the London-based Thai café concept led by Alex Moore, has secured £500k of new funding and two new sites in Chelsea and Angel as it looks to grow from four to 10 London restaurants by the end of 2017, M&C Report understands.

The investment has been secured from three private investors via the UK Angel Investment Network. It was provided in return for 10% of the company, valuing the group at £5m.

Both new sites, which are situated within Grade II listed buildings, will open this October. Each restaurant will offer 60-65 covers.

The new funding  comes on the back of Rosa’s being just one of 30 companies out of 15,000 selected by GrowthAccelerator, the UK based government-backed partnership between leading private sector growth experts, as a HyperGrowth business.

A HyperGrowth business is one that has grown at an extraordinary rate of at least three times higher than the accepted definition of ‘high growth’. The latest investment round was secured with help from one of the scheme’s Growth Accelerator coaches Tom Kristensen.

The original Rosa’s founders, British husband and Thai wife team, Alex and Saiphin Moore, will continue to independently operate the brand and oversee its growth.

Alex Moore said: “We are very excited to announce this investment. We were oversubscribed and chose to work with like-minded people that would allow us to retain Rosa’s independence, values and integrity as the brand grows.”

The first Rosa’s Café opened in Spitalfields in 2008, followed by Soho in 2010, Westfield in 2011 and most recently Carnaby Street last year.
