Turtobook is an innovative Hong Kong and overseas dive trips and courses booking platform that strives to make diving easy, social and affordable. We adopt an originative booking approach to automatically match available students and instructors. With our first funding from Cyberport’s CCMF program, we launched this platform in mid 2018 for beginners to book local courses and for certified divers to book local fun dives in a more convenient way. In November 2018, we registered as a Hong Kong travel agent and expanded our services to include overseas destinations, beginning with Philippines and Taiwan. In the future we plan to provide accurate and reliable dive site information by aggregating user- and operator-contributed data so divers everywhere can easily search for dive classes and destinations, read reviews and book all on the same site.
