This week’s Founder Friday, we sat down with Hyun Choi, co-founder of Altis Consulting, alongside her husband and co-founder, Gavin Cooke. At 2am in a Surry Hills studio, Hyun Choi and her co-founder Gavin Cooke were grabbing bites of Italian takeaway between all-nighters, racing to finish a feasibility study for Sydney Airport before their two-week deadline. That bet became Altis Consulting, an Australian-owned data and analytics consultancy that now employs more than 175 people across Australia and New Zealand. The company helps businesses, institutions and government agencies make sense of complex data, offering everything from advisory and AI services to consulting, managed data services and training.
