The Crowdcube campaign was launched last month and smashed its initial £1.5m target in just a few hours.
Having gone into 'overfunding', the group went on to raise a total of £1999,998 from 842 investors, before closing the fundraiser.
Ready Burger, which bills itself as the 'first value-driven, fully plant-based quick service restaurant in the UK', recently opened its debut venue in London’s Crouch End, and is set to open a second restaurant on Finchley Road later this summer.
A third and fourth site already planned, with the group eyeing 'rapid expansion' that targets 'densely populated, high footfall locations'.
Founded by entrepreneur Max Miller and chef Adam Clark, the former personal chef to boxer Anthony Joshua, Ready Burger serves a 100% plant-based menu at prices similar to those of fast food giant McDonald’s.
The brand’s signature The Ready Burger costs £1.99 and is described by its founders as the only plant-based burger of its kind on the market for under £2. Other options include The Big Ready (£3.59), The Chicken Challenger (£4.29), and the Saver Menu Double Cheeseburger (£3.39).
Ready Burger’s menu prices are significantly lower than many of the other new vegan burger concepts, including the Lewis Hamilton-backed Neat Burger, where burgers start at £6.49 with the option to add extras and whose eponymous Neat Burger costs £9.49.
Halo Burger has a similar price point, with a cheeseburger priced at £6 and its Halo Burger priced at £9.50.
