Redeam has enlisted the help of existing investors to secure a $12 million capital-raising program.
The Series B round was led by Vertical Venture Partners and Thayer Ventures.
Other existing backers participating in the investment include Peninsula Ventures and Cobre Capital, with Boulder Ventures coming onboard as a new financing partner.
The round follows a Series A package almost three years to the day to the tune of $8 million.
Redeam was created in 2015 as a channel management and voucher redemption platform for tour, activity and experience providers.
The latest round will be used to spearhead Redeam's expansion program and technology, the company says.
CEO Melanie Meador, who joined the company in May 2018, says the demand for technology in the tours and activities sector has "skyrocketed" since the coronavirus pandemic.
In a statement to announce the investment, she says: "Our products have evolved towards complete digitized and touchless solutions for the industry, white label solutions for hotels, airlines, and other travel products, and our workforce has not only proven its expertise in the space but also now exceeds diversity standards.
The company's three co-founders, CEO Kevin McLoughlin, Alex Kremer and Leith Stevens, left the business over the course of 2018 and 2019.
