Adam Callinan is the founder and CEO of Pentane, a profitability operating system for e-commerce and direct-to-consumer brands. Pentane emerged directly from the decade Callinan spent building BottleKeeper — a beverage insulator he co-founded with his cousin in 2013 — from zero revenue to $60 million in total sales and a private equity exit, running customer service, paid advertising, creative, and the website almost entirely himself. The core insight behind Pentane: most e-commerce operators are drowning in dashboards but can’t answer the one question that matters — are we profitable, and why — because no one has codified the right equations for them. BottleKeeper’s growth was neither gradual nor accidental. In August 2014, when Facebook launched its video ad platform, Callinan shot a clip of the product in motion and watched monthly revenue spike from $2,000 to $40,000 to $60,000 to $80,000 to $150,000 in a matter of months. He spent the next several years doing it almost entirely himself — handling customer service, paid advertising, creative, and the website — while his cousin managed finance and fulfillment. The company appeared on Shark Tank before eventually selling to a private equity buyer. Callinan lives in Bozeman, Montana, where he pursues hard physical experiences outdoors as deliberate mental conditioning — a framework he traces directly to resilience under business adversity. He actively mentors founders and business owners. Hey, Thanks for reading this. I mean that. There's a lot of content out there competing for your attention, and you spent some of it here. I hope it was worth it. Even better, I hope it prompted you to think about something differently enough that you'd share it with someone who'd get something out of it too.I started this podcast because tactics never stuck with me. What stuck were stories — business biographies, autobiographies, the decisions people made and why they made them. The principle only clicks once you know the story behind it. So I built the thing I wanted to read. Every week I have two conversations with people who build in technology and product. Then I write the essay I wish I could find — one that puts you inside the conversation, through my eyes. What caught me off guard. What I kept thinking about after we hung up. Where the principle actually lives once you strip away the jargon. I make this for myself first. If you read the way I do, you’ll want it too.
