Nano is a fintech start-up founded in Jan 2020 by Dzung Dang (ex-Uber GM and ZaloPay CEO) and Thang Nguyen (CTO Focal Labs).  VUI (https://www.vuiapp.vn) is a payroll product that pays workers daily instead of monthly for retailers and manufacturers in Southeast Asia. Employers compete with the gig economy for workers, which comes with a flexible work schedule and pays daily. With Nano, employees can get paid anytime they choose with a tap on their phone.
