What if the biggest reason we waste food isn’t laziness, but lack of transparency?In this episode of Tomorrow’s Bites, we sit down with Evelien Moriau, founder of Ostras, a startup that’s turning everyday grocery shopping into a data-powered tool to fight food waste, save money, and change consumer habits at scale.After years in consulting, Evelien made the leap into entrepreneurship with a simple but radical idea: if supermarkets won’t share real-time data about short shelf-life products, consumers can. Inspired by platforms like Waze, Ostras crowdsources supermarket data directly from shoppers—putting transparency and power back into the hands of the people.In this conversation, we unpack:Why sustainability alone doesn’t change behavior (and what does).How crowdsourcing can outperform top-down food waste solutions.The psychology behind habit change in grocery shoppingWhy food waste is a consumer problem as much as a supply-chain one.How incentives, not guilt, drive real impact.This is a grounded, honest look at what it takes to build a food tech startup that operates at the intersection of behaviour, data, and climate impact, without relying on idealism alone.🎧 Listen now to discover how small daily actions, multiplied by millions of people, could quietly reshape the food system.🙏 LEAVE A REVIEW If you like our podcast please leave us a review on your favourite platform – even one sentence helps!
