PerfectTed is the world’s largest matcha brand. Co-founder Marisa Poster’s search for energy that didn’t come at the expense of her mental health led her to matcha – coffee and energy drinks made her ADHD and anxiety worse and she found that matcha changed her relationship with caffeine. Marisa launched PerfectTed alongside her husband Levi and his brother Teddie Levenfiche in October 2021. Their drinks are now stocked at more than 35,000 stores across 50 countries. The founders secured investment from Steven Bartlett after appearing on Dragon’s Den in 2023, and have since added Felix Capital to their investor base. Sales jumped to £29m in 2025.
