Ando Technologies

San Francisco

Ando is building the world’s first AI infrastructure for the global hourly workforce – technology designed to finally fix the chronic mismatch between people, schedules, and demand. Every year in the U.S. more than 80 million hourly workers log over 140 billion hours, yet the systems responsible for staffing those hours remain deeply broken. Managers struggle to predict demand and build reliable schedules, while workers juggle multiple jobs, inconsistent hours, and impossible tradeoffs between shifts, childcare, and daily life. Businesses lose more than $5,800 each time an employee leaves, turnover regularly exceeds 150%, and many stores lose $5,000 or more per week simply because they do not have the right staffing when customers show up. Ando exists because this system is failing both sides. By giving workers predictable schedules that align with their lives and giving employers accurate AI-powered staffing intelligence, Ando reduces turnover, cuts labor waste, and brings stability to frontline operations.
