In this episode of Mostly Growth, CJ Gustafson, Kyle Poyar, and Ben Hillman dive into the question on everyone’s mind: are we in an AI bubble? What starts as a lighthearted riff on the U.S. Postal Service launching a podcast quickly spirals into a sharp, funny breakdown of today’s AI hype cycle — from Nvidia, OpenAI, and AMD trading money and GPUs in a trillion-dollar feedback loop, to startups burning cash chasing “AI-powered” everything. The trio share real examples of when AI helps and when it backfires (including one newsletter that totally tanked), debate whether companies are over-optimizing for automation, and laugh through the absurdity of the hype while grounding it in practical insights on product, finance, and growth.

Today’s podcast is brought to you by Metronome
You just launched your new AI product. The new pricing page looks great. But behind it? Last-minute glue code, messy spreadsheets, and running ad-hoc queries to figure out what to bill. Customers get invoices they can’t understand. Engineers are chasing billing bugs. Finance can’t close the books.
With Metronome, you hand it all off to the real-time billing infrastructure that just works—reliable, flexible, and built to grow with you. We turn raw usage events into accurate invoices, give customers bills they actually understand, and keep every team in sync in real time.
Whether you’re launching usage-based pricing, managing enterprise contracts, or rolling out new AI services, Metronome does the heavy lifting so you can focus on your product, not your billing.
That’s why some of the fastest-growing companies in the world, like OpenAI and Anthropic, run their billing on Metronome.
