Showcasing the Best of Welsh Business


Theo Paphitis Sends Local Business Letterbox Lab to Prestigious Trade Fair


Small business champion and former dragon Theo Paphitis provided a boost to local business, Letterbox Lab, this month by awarding them the opportunity to showcase their products at the Autumn Fair.

Mia and Bryan Hatton launched Letterbox Lab in 2017, to put exciting science experiments through families’ letterboxes from their base in Taff’s Well. Their two series of science kits have since been shipped to families across the United Kingdom to the delight of curious children.

Letterbox Lab was one of the twelve winners of Theo Paphitis’ competition arranged with the Autumn Fair for members of his Small Business Sunday (#SBS) network. #SBS is a network for winners of Theo’s weekly Twitter competition, which Letterbox Lab won in October 2017.

Recent winners of the Silver Award for Best Kids’ Subscription Box in the Junior Design Awards, and finalists in the retail category of the upcoming Wales Start-up Awards, Letterbox Lab is on a mission to spread their innovative approach to learning science through play. Attending the Autumn Fair gave Mia and Bryan the opportunity to meet potential stockists and explore new ways to empower children to discover the Universe from the comfort of their home.  They also met with Theo Paphitis and gave him a go on their Rainbow Glasses (which turn the world into rainbows) when he visited their stand in the SBS Pavilion.

“This incredible opportunity was the icing on the cake of an exhilarating month! We had been talking for months about how great it would be to meet a few retailers and get our products in front of them, so when Theo announced this competition it almost seemed too good to be true”
