Sixley is a recruitment platform that helps companies fill roles through personal recommendations rather than traditional headhunters. Launched in 2019, it lets a hiring company ask its extended network, including staff, alumni and industry contacts, for referrals, typically within about ten minutes. Referrals go straight to the hiring manager rather than being filtered through an agency, and successful recommendations are rewarded from the fee. Clients range from 40-person startups to corporations with over 100,000 employees, including BT, which signed a wide-ranging agreement in 2023 to use the platform across BT Digital.
