A series B round of $21 million has come to Travelperk from a group of new and existing investors in its bid to "fix business travel".
The latest injection of capital has come via Target Global and Felix Capital, with participation from previous backers Spark Capital and Sunstone.
Travelperk, a travel booking and management platform for businesses, has now raised a total of $30 million.
The company launched in January 2015 by Javier Suarez and Avi Meir, who was previously the creator of Hotel Ninjas, a Spanish startup which was later sold to Booking.com where Suarez was previously involved in business development.

It claims to have built the "world's largest bookable inventory" for businesses, integrating with hotels, airlines and rail companies, using inventory from Booking.com, Expedia, Airbnb and the global distribution systems.
The latest round will be used to expand the company, especially the workforce which it hopes to double to around 200 people in up to five new offices globally by 2019.
Max Niederhofer of Sunstone says: "In business travel, companies have two bad options: either antiquated enterprise agencies that are both crappy and expensive, or a mess of consumer tools that result in a flurry of invoices, payment methods and general confusion.
"Travelperk fills that gap - it hides the complexity from the traveller by offering a complete end to end solution and not just a sexy interface (it also has a sexy interface)."
