Alcuin Capital Partners has invested an undisclosed amount into the company, with original founders Jay Lakshman and Scott Braidwood holding the remaining stake.
The London-based operator specialises in group tours, tailor-made holidays and adventure itineraries. A spokesperson said that the cash injection would be used for expansion.
In a statement, Braidwood said: “Both Jay and myself will remain on the board and look forward to helping steer On The Go onwards in this exciting new chapter in our journey.”
Managing director Carl Cross added: “After having grown the business significantly over the past three years, this new investment is the start of a new phase in the life of On The Go Tours.”
