This week, we sit down with Marisa Poster, the co-founder behind PerfectTed, the matcha-powered energy brand that's become Europe's biggest in under five years.A caffeine-addicted finance grad with an ADHD diagnosis she was too ashamed to admit, Marisa discovered matcha face-down in a university library after one crash too many — then moved to London and found a country that didn't sell it. Forty-five days after landing, she and her co-founders (her husband Levi and his brother Teddy) had incorporated the business. Five years on, PerfectTed is Europe's #1 matcha brand — stocked in 40,000+ points of distribution, valued at over £140m, and one of the largest matcha buyers on earth.From a matcha latte that never made it to market, to a can you can't miss on a supermarket shelf, this is a masterclass in turning a niche obsession into a mainstream category.Marisa breaks down why she treated Dragon's Den as a pure marketing play — studying every pitch that ever pulled all five offers, and memorising the exact glue on her labels in case a Dragon asked — and why she still chose Steven Bartlett's money over bigger names. She gets candid about hiding her ADHD for years, convinced it made her less credible as a founder. And she shares how PerfectTed scaled nationally on almost no paid ads, by turning supermarket shelves into billboards.She also addresses the elephant in the room — the global matcha shortage — with maybe the most honest line a founder's ever given about their own success: ”I don't want to say we caused it, but…”Strategic, candid, and packed with brand lessons you won't find in a marketing textbook.Timestamps:00:00 Building Europe's #1 Matcha Brand00:50 ADHD, Anxiety & Finding Matcha in a Library03:54 Moving to London to a Country With No Matcha05:49 Why the Energy Category Overlooked Women13:01 45 Days to Incorporate & the Pivot to Cans16:18 The Name ”PerfectTed” & Buying From People21:08 Dragon's Den Packaging & the ”Healthy Energy” Pivot24:08 Why the Brand Is Green: Nature's Neutral27:14 Building With Her Husband & His Brother30:54 Why Fun Is a Prerequisite for Success34:20 Kickstarter Selling Out in a Day36:49 Treating Dragon's Den as a Marketing Play40:21 Choosing Steven Bartlett: ”Take Smart Money”43:36 No Paid Ads & the Global Matcha Shortage45:48 Cracking Retail: Shelves as Billboards51:16 What's Next: Protein Lattes & New Categories53:33 The Heinz Collab TeaseFollow us across our socials:Twitter: https://x.com/happystackhqLinkedIn: https://www.linkedin.com/company/happystackhqInstagram: https://www.instagram.com/happystackhqCheck out the HappyStack website: https://www.happystack.com/Stack the odds. 🥞#ecommerce #podcast #founder #business #happystack #thelockin
