Kantoko is an ADHD telehealth platform connecting Australian adults with AHPRA-registered psychiatrists and GPs entirely online. The platform guides patients through a four-step process — online self-assessment, GP referral with routine tests, telehealth appointment with an ADHD specialist, and ongoing care coordination — with a focus on diagnosis, personalised treatment plans, medication management, and prescription renewals. Operating under a subscription model, Kantoko targets the estimated 75% of Australian adults with ADHD who remain undiagnosed due to long wait times and high costs in the traditional healthcare system. The platform serves patients across NSW, QLD, VIC, TAS, ACT, and SA. Founded in 2023 by Zac Altman, whose previous company LoungeBuddy was acquired by American Express, Kantoko raised an oversubscribed AUD $3.5 million Seed round backed by Side Stage Ventures and Tenmile.
