Tourlane has topped up its Series C investment round from 2019 with an additional $20 million from existing financial backers.
The company, which specializes in providing customized multi-day packages, has now attracted north of $100 million in investment over four years.
The Series C expansion round includes support from Sequoia Capital, Spark Capital, DN Capital, and HV Capital, alongside both founders, co-CEOs Julian Stiefel and Julian Weselek.
Tourlane says the investment will be used to continue its product development program and "secure financial stability" of the business.
The Germany-based company landed a $47 million in Series C funding in May 2019, just five months after its Series B round of $24 million.
The online service has products in 50 destinations around the world and secures flights, tours and activities, accommodation and transfers in one transaction.
Stiefel says the coronavirus pandemic has given the industry the chance to "rethink travel" - in particular, as a catalyst for providing end-to-end travel.
Weselek adds: "When the crisis hit us earlier this year, our team made an incredible effort to adjust strategy, adapt to a new reality and get ready for the new demand when the market bounces back."
The company was founded in 2016 and has angel investors including Airbnb founder Nathan Blecharczyk, GetYourGuide founder and CEO Johannes Reck and Trivago’s founders.
