Tej Lalvani joined the British television series Dragon's Den in 2017.
Lalvani became a Dragon in the fifteenth series, joining the BBC programme's established investor panel. He is a British businessman associated with Vitabiotics, the family-owned health and wellness company founded by his father, Kartar Lalvani. His business background brought experience in consumer healthcare and branded products to the Den.
His arrival followed several earlier changes to the panel, so it is useful to distinguish 2017 from the years when other later Dragons joined. Sara Davies arrived in 2019, while Steven Bartlett joined in 2022. Those dates belong to separate changes in the programme's line-up.
The year refers to Lalvani's debut as a television Dragon, not the founding date of Vitabiotics or the beginning of his wider business career. Dragon's Den series numbers and broadcast years can also differ slightly because a series may span more than one calendar period.
