Sydney-sider Zac Altman’s first legit startup was a taxi booking app called Taxi Pro that Zac developed and built in his final year of high school. Before Uber had hit the ground running in Australia.

Greater success was to come with his 2nd venture. Still in his teens Zac moved to San Francisco and created and co-founded with 2 new mates the travel startup called LoungeBuddy, which enabled travellers to discover, book, and access over 400 airport lounges around the world, via the LoungeBuddy website or app.

After 7 years of slogging it out building up the business, with myriad challenges along the way, the trio built LoungeBuddy to have over 100,000 users every month. In 2019, the young founders sold LoungeBuddy to global giant American Express, reportedly for in excess of $100million. Zac Altman was in his mid-20’s. So how do you build not 1, but 2, successful startups, and where to from here for Zac Altman? 1/2
