Travel Impact was rebranded as TI and staff moved out of offices in Richmond in January to join the Vantage Point team in Wimbledon.
Three staff were made redundant, taking the team from 13 to ten.
"We integrated the staff and systems. (Travel Impact founders) Ray and Susie Roberts are still part of the team and on a two-year contract," said Vantage Point managing director John Denham. "The integration has gone very well."
