Klook will use a new investment round of $200 million to "reimagine the next digital leap" for the experiences sector.
The Series E backing is being led by Aspex Management and includes a number of new investors. Previous backers, including Sequoia Capital China and Softbank Vision Fund, are also participating.
The new round brings the total raised by Hong Kong-based Klook to more than $720 million since the company's launch in 2014.
Its last investment was a $225 million Series D round in April 2019.
The new capital will be used to continue Klook's program of building software for merchants in the tours, activities and experiences sector - a strategy that became a major part of its pandemic period activity in 2020.
Klook also expanded beyond its core and original proposition to launch new verticals covering accommodation packages and car rental.
The company claims its software helped onboard 150% more activities during the height of the pandemic compared the corresponding period in 2019.
More than 2,500 merchants are now using its tools to power their bookings and websites, Klook says.
Hermes Li from Aspex Management believes Klook has the "ability to reinvent itself as a one-stop-shop for experiences and services across the region" as travel initially returns for domestic markets and then when international trips kick in.
Klook, alongside Traveloka, Trip.com, Changi Travel Services and GlobalTix, was named in late-2020 as an online booking partner for the Singapore Tourism Board’s S$320 million recovery program.
Known as SingapoRediscovers, the program gives every Singapore citizen age 18 and above S$100 (about $75 USD) worth of vouchers that can be spent on more than 200 hotels, attractions and tours that are participating in the program.
