“I think a lot of folks like myself never even get a chance, because folks don’t answer their phones, or listen to their idea, but put them in a box they shouldn’t be in,” says Zack Smith, the founder of Boston-based Jobble.

He’s talking about how hard it can be for black tech entrepreneurs to raise money.

But Mr Smith saw it as a challenge.

“It doesn’t matter what box they put me in to begin with, I’ll get out of that box and prove to them I’m bigger and better. I think this fuels me,” he says.

His firm is a US platform for jobs in the gig economy, offering work to those who want flexible hours.
