Impossible Foods, which makes meat-free plant-based burgers, has raised a further $300m in a latest round of funding ahead of a possible initial public offering.

The latest round brings the Silicon Valley-based start-up’s total raised to more than $750m.

Celebrities including Jay-Z, Will.i.am, Jaden Smith and Katy Perry and Serena Williams, have backed the company.

Institutional investors include Khosla Ventures, Microsoft Corp co-founder Bill Gates, Google Ventures, Horizons Ventures, UBS, Viking Global Investors, Temasek, Sailing Capital, and Open Philanthropy Project.

The fifth equity funding round since its launch in 2011 values Impossible Foods at $2bn.

Burger King has said it will launch ‘Impossible Whopper’, which uses Impossible Foods’ plant-based patties, nationwide after a successful trial at limited locations.

Impossible Burger is sold at more than 7,000 restaurants worldwide.
