William Zeqiri studied Information Systems at the University of Auckland from 1999 to 2002. During his degree he worked as a contract software engineer for several companies.
After graduating he co-founded MacroWeb, a web development and hosting company, and became its CTO. He also consulted on IT for Air New Zealand and Auckland Hospital, and earned the Project Management Professional credential in 2014.
In April 2015 he founded the company with Nick Miller under the name Shedul, based in London. It was renamed Fresha in 2020. The software is free for salons, barbers and spas, and Fresha earns from payments and a consumer marketplace.
Fresha has more than 50,000 businesses and handles more than 20 million appointments a month. In May 2026 a KKR led investment of about $80m valued it near $1bn. Run-rate revenue is above $140m and the company is profitable.
