Hi Product Hunt 👋 I’m Ago, founder of VALERI and I’m excited (and slightly nervous!) to share this with you today. What inspired this? The 40oz tumbler market exploded over the last few years. Everyone owns one. But when I looked closely, I realised something interesting: Innovation had stalled. Most tumblers focused on size and insulation. None addressed something incredibly simple control. You still guess when your coffee is drinkable. You still test-sip and burn your lips. You still wonder if your iced drink is actually cold hours later. That friction felt unnecessary. So we asked: What if a 40oz tumbler wasn’t just insulated but intelligent? That question became the Smart Temperature Lid™. What problem are we solving? Hydration shouldn’t involve guesswork. We built VALERI 2.0 to: • Eliminate “trial sips” • Remove burnt-lip moments • Give real-time temperature awareness • Combine durability + smart simplicity It’s not about adding complexity. It’s about adding clarity. How did the process evolve? The original VALERI 40oz focused on durability and performance triple-layer insulation, leak resistance, long-term reliability. But through customer feedback, we kept hearing one thing: “I love it but I wish I knew when my drink was ready.” That insight changed the direction completely. Instead of redesigning the entire tumbler, we evolved it into a modular system — so you can keep the body and upgrade the lid. Smart where it matters. Durable everywhere else. We’re now live on Kickstarter and already have our first production batch completed this isn’t a concept render. It’s production-ready hardware. I’d genuinely love your feedback especially from builders and hardware founders here. What would you improve? Would you use temperature awareness in a 40oz format? https://www.kickstarter.com/proj...
