Sisters Evie Calder and Francesca Watson are behind the Atlas & Ortus brand, which sells eco-friendly items such as toothbrushes, drinks bottles and bags.
Their Speldhurst-based firm is now expected to make a major breakthrough, thanks to the exposure gained through Small Business Sunday.
Former Dragons Den star Paphitis, 58, holds the weekly competition on Twitter where entrepreneurs can pitch their services.
He will retweet a small handful of his favourite firms to have tweeted #SBS. These winners, usually five or six, will benefit from online exposure and invitations to events and conferences.
Atlas & Ortus only formed five months ago and the sisters are operating from their parents’ house. But they are now featured on Paphitis’ website and their #SBS tweet has been seen more than 11,000 times.
Evie Calder said the support has been ‘amazing’ and the chance to make a difference to the environment had inspired the firm to start.
She added: “There are so many new businesses trying to tackle the plastic pollution problem like we are, so it’s been incredible having Theo recognise our hard work and helping spread the word about what we do to his following.”
Theo Paphitis said: “We are thrilled to welcome new #SBS members every week and highlight just how important it is to support our small businesses here in the UK.”
