Iglu.com founder Richard Downs has joined experiential travel specialist as chair to drive the operator's "next phase of ambitious expansion".
NITGBs said the funding, which has been led by Maven Cognition, will power its growth into new destinations while accelerating investment in its technology.
This, it said, would make it "faster and simpler" for travel agents to discover, package and book its itineraries, driving a new era of "agent-led experiential travel".
Downs founded Iglu in 1998 and grew it into one of the UK's largest online agency businesses; it was acquired by Flight Centre Travel Group for upwards of £100 million late last year.
