Keith Lesser is the Founder and Managing Director of Vegan Accountants. Keith became vegan in 2017 and in 2020 acquired Vegan Accountants to align his vegan ethics with his passion for accountancy. Keith formed the Vegan Business Mastermind in 2025. His firm aims to provide high quality financial advice to those that are helping to create a vegan world.

Keith was heavily influenced by his first-ever vegan client Idan. Idan was passionate about veganism and this passion had a life-changing impact on Keith. When one of his clients died of cancer in his 50s and another had a heart attack in his late 60s, Keith thought there must be another way. The death of 2 clients within 2 weeks lead Keith to make new choices about his health.

Not long after becoming vegan for health reasons, the ethics around animal cruelty and the sustainability values around our planet and climate change became just as important. Keith felt the natural progression was to combine accountancy and veganism and serve the vegan business community with quality accounting services. He acquired the Vegan Accountants brand, built a vegan team and re-vamped, re-launched and later re-branded the business with significant growth of 500% in the first 24 months.

Vegan Accountants still operates alongside the family business Lesser & Co, with a dedicated fully-vegan team. Here at Vegan Accountants, our mission is to help vegan businesses succeed with solid foundations for their financials and quality advice. Having a fully vegan supply chain is a big goal for vegan and ethical businesses and we’re here to help you to achieve that by giving you a vegan accountancy partner. We don’t see veganism as a trend. It is a positive trajectory towards positive financial and physical health, the elimination of animal cruelty and collaboration to achieve sustainable living.
