Over the past six months, the startup has seen a “10x” increase in Selfbook users using single sign-on and digital wallets. This, the company says, can drive more upsells for the hotels and as a result, increase revenue.Image Credits: Selfbook In order to facilitate those bookings, the company created its own “modern” transaction software after discovering there were no existing API partners with a simple hotel booking function on the market. Investors such as Better Tomorrow Ventures, Abstract Ventures, TenOneTen Ventures and 9Yards Capital participated in this latest round, as well “with super pro rata.”Selfbook claims that its software gives hotels a way to accept “one-click” payments directly on their websites while eliminating fraud and reducing chargebacks. Selfbook claims that its software is the only payment technology for hotels that supports digital wallet use, including Apple Pay, Google Pay, PayPal and buy now, pay later. Today, Selfbook has 50 full-time employees, up from only four employees at the beginning of the year. As mentioned above, Selfbook formerly operated as a B2C business that gave hotel guests a way to book reservations at over 3,000 hotels using its SIX Travel app. “Selfbook is a joy to use, and is obviously the future.”Side note: After booking a hotel earlier this year through a third-party provider and having a nightmare experience to just cancel the booking, I can appreciate the need for this sort of technology.
