Happiour, a London-centric app that offers time-sensitive restaurant and bar deals, is crowdfunding to raise finance to expand.

The group, backed by DN Capital - which backed Shazam; Michael Birch - the founder of Bebo; musician Mark Sheehan and Paul Donovan the chief executive of Odeon, is raising £750k on Crowdcube in exchange for 15% equity.

Founders Hal and Sharmita Stokes are raising the funds via the online platform to expand the model nationally by growing its user and vendor bases as well as its own operation and technology team.

The company is currently free to use but will monetise from March 2016 with a monthly fee for vendors to share Happiour promotions.

Sharmita Stokes told M&C the company partnered with Starbucks for a recent campaign that saw more than 2200 redemptions in a single morning for a breakfast promotion.

It has also partnered with bakery-café group Apostrophe in conjunction with Cadbury to test the market new products launched in the coffee shop targeting 18-35 year old core market.

Happiour is now used at more than 400 restaurants, bars and coffee shops across London to promote hyper-local promotions.

The platform, which hosts established brands and independent operators, will be going nationwide from January 2016 when a number of key cities will be added including Leeds, Manchester, Brighton, Reading and Oxford.
