Bessemer Ventures is leading a $10 million Series A round into U.S.-based corporate travel platform specialist Pana.
The funding is also supported by participation from Techstars, MergeLane Fund and Matchstick Ventures.
Pana has now raised $11.5 million over the course of three rounds - its previous funding coming shortly after launch in 2015 to the tune of $1.4 million.

The company started out as an on-demand travel concierge service, with users being encouraged to send a message via its app to request flight bookings, hotels, car rental and restaurant recommendations.
Pana would then reply with details to each user, using a model or a two-tier monthly payment.
Since its foundation Pana has pivoted to serving travel managers and those making bookings on behalf of groups.
Customers include Quora, Shopify, Logitech and, according to CEO Devon Tivona, around 100 other companies.
The company is pitching the service at both large corporates and smaller businesses, with the former working alongside existing contracts with suppliers.
BCD Travel was a marquee deal signed by the company in 2018, alongside another later the same year with AirHelp to streamline payments.
Kristina Shen of Bessemer says: "The corporate travel industry is about to undergo a very similar metamorphosis that we’ve seen in the taxi industry with Uber and Lyft, online shopping and delivery services with Amazon, and short-term rentals with Airbnb."
Corporate travel startups have become increasingly in vogue over the course of the past year, attracting the attention of some big names in the funding world and the injection of millions of dollars of capital.
TripActions raised $154 million in November 2018, bringing its total to date up to $232 million.
The TripActions investment followed a Series C round of $44 million for TravelPerk, announced the month before.
Tivona adds: "We’ve been able to scale a global agent operations team with sustainable economics. And now, Pana can begin applying our hybrid digital and human platform to other complex and important travel workflows that are painful for our customers today.
"If a clunky spreadsheet or a dozen emails back-and-forth are required to get a trip together, we believe Pana can and will help."
