Quick one for anyone with an AI feature in their product (support box, summariser, draft-a-reply button) 👋 🔬 A research lab sent one prompt to one model 1,000 times with randomness turned off. 80 different answers came back. You can't control which one a customer gets. 💸 Air Canada found out the expensive way: their chatbot invented a refund rule, and a tribunal made them pay CAD $812 for a sentence the bot made up. 🧪 This week's newsletter is the routine I use to catch that BEFORE a customer does: 20 real questions, a pass rule for each, run every one 5 times, 100% bar on anything about money. Exact config file included. 👉 https://rapidflowautomation.beehiiv.com 💬 What's the ONE question you'd hate to see your AI feature answer wrong in a customer's screenshot? Drop it below and I'll suggest the pass rule for it.

Quick one for everyone building here 👋 I went through a dozen public founder postmortems on free plans this week. The pattern hit hard: 📉 Median freemium conversion is 2.6% — so roughly 38 free users ride on every 1 paying customer 🔥 Baremetrics converted DOUBLE the benchmark and the free plan still nearly broke them 🤖 And if your product calls an AI, every free click costs you real money — one founder woke up to a $700 bill overnight I wrote up the full 5-step math in today's newsletter — what one user costs you, how many free users you carry, and the 20% line that says keep your free plan or kill it: https://rapidflowautomation.beehiiv.com 🧮 Curious about this group 🤔 — do you run a free plan right now, and have you ever calculated what it costs you per month?
