Existing investors in booking platform provider Nezasa are behind a fresh round of $6 million.
The latest injection brings the total raised by the Switzerland-based company to $13 million.
Nezasa will use the capital to expand its TripBuilder platform to intermediary partners in the travel agency, online travel agency and tour operator sectors.
The tool allows partners to create itineraries and bundles of products during sales to customers.
The round is the first for the company since it raised a $2.5 million Series A investment almost two years to the day from Howzat Partnerrs, Alpana Ventyures, Reinhart Capital and Investiere.
Customers include FTI and DER Touristik.
The company was formed in 2013 by Manual Hilty, Patrick Hammer and Andreas Furer.
CEO Hilty says the post-COVID-19 market will require "even bigger digitalisation of all travel sellers."
"We are well-positioned to capture the market and are seeing a strong increase in enquiries from small to very large travel brands and OTAs to adopt our suite of planning and booking tools into their processes.
"In the last six months, we have been laser-focused on making our platform easier to adopt and on supporting those travel trends that have become more prominent in the current situation."
