Hotel Engine, a corporate booking platform, announced a $140 million Series C investment and a name change to reflect the coming launch of flight and rental car reservations. The investment was led by Permira Growth Opportunities II, a fund advised by global private equity firm Permira.

Hotel Engine will use the funding to support ongoing product development, including the launch of flight and rental car bookings to its platform. The new booking options will go live in October, making Hotel Engine an all-in-one solution for business travel, the announcement said.

Alongside the new product release, Hotel Engine will change its name to “Engine” to reflect its expanded focus. Elia Wallen, Hotel Engine’s CEO, said: “Hotel bookings will always be in our DNA, but we’re out to transform the entire travel experience. We want to become the engine of business travel. Our new name will reflect that, and with Permira’s latest investment, we’ll be better positioned than ever to turn our ambitions into reality.”

Denver-based Hotel Engine says it offers innovative features like consolidated invoices, coverage for incidentals, 24/7 customer support, whole-company trip insurance and free travel-management software to help customers save time and money. Hotel Engine’s contract-free approach with no minimums or agent-assist fees, according to the company, makes adoption easy for businesses of all types and sizes.

Hotel Engine connects business travelers to a network of more than 750,000 hotels, 300 airlines and 40 rental car companies. Travel providers are also able to use Hotel Engine’s Partner Hub software platform for free, which enables them to provide special offers to business travelers, manage reservations, create marketing campaigns and benchmark against competitors.
