Hypothesis Engine by GrowthFuel

Hey PH 👋 I'm Gustavo, and after 20 years leading growth across startups, and teams at Shopify, and Dropbox, this is the tool I wish I had years ago. Too many experiments fail not because of bad ideas… …but because the hypothesis was never clear to begin with. So I built the Hypothesis Engine: ✅ An AI-powered coach to turn fuzzy growth ideas into testable hypotheses ✅ Confidence scoring (1-5) based on structure, clarity, and logic ✅ One-click rewrites with instant improvement suggestions ✅ Sample size calculator and community benchmarks ✅ Built 100% on Lovable: no engineers needed I believe prototypes are the new content—and this is my first stake in that future. It was built in <10 hours using only AI tools, no code. If you're a growth leader, PM, or startup founder, give it a try and let me know what you think. No sign-up, no fluff. Just clarity. 👉 hypothesis.growthfuel.ca Would love your feedback, ideas, and support. Thank you for checking it out! Gustavo
