The acquisition will see OAG grow to more than 300 employees globally across 10 offices, and will combine OAG’s existing data tools with Infare’s airfare data.

Both management teams will stay in place and will retain a shareholding, with fresh financial backing provided by London-based growth capital firm Vitruvian Partners.

Infare is a competitor air travel data provider that was set up in 2000 and is headquartered in Copenhagen.

Phil Callow, chief executive at OAG, said: “The increasing dynamism in global travel and technology is fuelling a need for more sophisticated, granular data to understand, manage and unlock growth in air travel.

“The acquisition of Infare strengthens our ability to deliver consistent and accurate information across the wider supply and demand value chain.”

Nils Gelbjerg-Hansen, chief executive at Infare, added: “Our technology platform, data sets and intelligence software complement OAG’s and will greatly benefit our customers worldwide.

“We see this as a unique opportunity to expand our services and introduce new innovative products for our customers, we are excited about the journey ahead together.”

Ben Johnson, partner at Vitruvian Partners, said: “The combination creates additional growth opportunities for both teams. Vitruvian is delighted to support this ambitious technology company and renew our relationship with them for the years to come.”

Niclas Gabrán, managing partner at Ventiga Capital Partners, added: “It has been a pleasure working together with Nils and his team to build Infare into a leading travel data provider through organic growth and acquisitions.

“Infare’s next chapter as a part of the OAG family will undoubtedly create further growth opportunities both within and outside the air travel sector.”
