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.

Cynch AI

San Francisco

Most financial decisions are made without expertise, analysis, or data. Meanwhile, the most successful people and companies have access to expensive consultants with deep financial expertise. Our vision is to level the playing field. We’re combining reasoning, machine learning, and generative AI to capture financial expertise and make it available to everyone. We’re initially focused on small businesses, helping them to achieve better outcomes for their owners, their employees, and their communities. How do you combine reasoning, machine learning, and generative AI? For us, this is the most interesting and challenging problem in AI today. Accounting is a “goldilocks” domain for tackling these problems — it’s sufficiently constrained to be tractable but sufficiently complex to require something new. Accountants will tell you that accounting is all about rules, judgement, and understanding your client — reasoning, learning, and generative AI. We are a seasoned team that is excited to take on a big technical challenge with a big impact. We care about the ethical implications of our work and are excited to work with others that do too.
