After the death of George Floyd in May 2000 and the Black Lives Matter movement, Lloyds and Channel 4 looked at the challenges faced by black entrepreneurs.
Nearly half of the businessmen and women they surveyed said they needed marketing and PR advice and a fifth help to find new clients.
Elyn Corfield, CEO of business and commercial finance at Lloyds Banking Group, said: “We are thrilled to announce the beneficiaries of the Black in Business initiative.
“The impressive number of applications speaks to the remarkable entrepreneurs who applied, highlighting the vast breadth and potential of black entrepreneurship in the country.
“This initiative builds on our commitment to support black-owned businesses and marks significant progress towards our long-term goal of creating equity for black-owned businesses.”
Clare Peters, of Channel 4, added: “Devising and running this important scheme has been an absolute privilege for the team, who are often at the forefront of providing platforms for lesser-heard voices.
“When our research highlighted the obstacles faced by black-owned businesses, we wanted to make a tangible difference by offering practical support to directly target some of the issues.
“It is our sincere hope that this scheme kickstarts wider awareness of the challenges faced and prompts action across the industry to deliver more equal opportunities for all entrepreneurs and business owners regardless of their background and ethnicity.
“I’m absolutely delighted for the five successful beneficiaries of this year’s scheme, and we’re looking forward to working with them to create five epic TV campaigns that supercharge the growth of their businesses.”
