In this special episode of Growth Mavericks, host Adam Callinan flips the mic on himself — re-airing his guest interview from EcommerceFuel
with Andrew Youderian. Together, they unpack a decade of lessons in building, selling, and reinventing how founders think about business, risk, and profitability.
Adam shares how fatherhood reshaped his approach to risk and time, why working 70-hour weeks crushed his soul, and how he and his partner built BottleKeeper to $60M in total sales with only six people - before selling the company.
They dive deep into the real math of profitability - why most e-commerce brands are guessing with their ad budgets, how discounting destroys margin, and how Adam’s latest SaaS company, Pentane.com
, helps founders finally connect marketing spend with financial performance.
