How do you test a bloodstain remover when you're still at school? You keep pig's blood in the teachers' fridge.Jozef Domonkoš, Dominika and Matej are three of the student founders of Aima, from a grammar school in Košice, Slovakia. The idea came up on a train ride as a joke. Their classmates said it wouldn't work. Three months of testing in the school lab later, every day after class, they had a formula that removes bloodstains from clothing in about 30 seconds.In this episode they share:• How they went from 10–15 candidate substances to one working product• Why they named the brand before they had a prototype (”Aima” is Greek for blood)• Building a brand on soft colours that signal safety, not stress• Bottling and labelling a few hundred units in school after lessons, then moving into their own lab space• Placing third among Europe's student companies and taking part in Samsung Solve for TomorrowTwo years in: over €17,000 in turnover, a 90% gross margin and sales in six countries, while they head off to university in different countries.Their message to the next generation: don't be afraid to dream, and take more risks.What's stopping you from testing your idea?#TheGoodIdeasClub #Innovation #StudentEntrepreneurs #YoungFounders #Startups #ProductDevelopment #Entrepreneurship #JuniorAchievement #SolveForTomorrow #Slovakia #Branding #grassrootsinnovation The Good Ideas Club Podcastwww.inso.ggwww.aimasf.skMusic: ”GOOFY” by Beast Inside Beats, Bargholz.Chapters:00:00 Intro01:10 Meet the Aima team02:48 An idea born on a train04:57 Three months in the school lab08:40 Pig's blood in the teachers' fridge10:13 The name, the brand and the colours13:52 Bottling, labelling and their own lab15:57 Sales channels and markets17:43 Growing the business through university20:38 Junior Achievement and Samsung Solve for Tomorrow22:52 The most fun and the hardest moments26:29 Customer stories27:41 How it works30:26 The one-minute pitch34:06 Buyout and investor interest37:03 Advice to their younger selves
