Lean, Profitable, and Free: How Alexandra Cristin Scaled Smart and Sold Big Oct 22, 2025

Show notes

In this episode of the Growth Mavericks Podcast, host Adam Callinan sits down with Alexandra Cristin, founder of Glam Seamless, to unpack an extraordinary journey — from growing up in poverty to building and selling an 8-figure eCommerce brand. Alexandra shares how she turned $1,500 and two shades of hair extensions into one of the most recognized online brands in the beauty space — without paid ads. She credits SEO, relentless content creation, and the power of constraints for forcing creative, profitable growth. After scaling Glam Seamless to over $10 million in annual revenue, Alexandra sold to private equity — and learned the hard way that staying on post-acquisition can drain even the most driven founder. From burnout to rebuilding her passion, she opens up about her biggest lessons on leadership, legacy, and self-restoration.

Adam and Alexandra also dive into:

How constraints can be a superpower in business
Scaling without losing control (or your sanity)
Why founders often spend recklessly after success
Navigating burnout and rediscovering purpose
The truth about private equity deals and earnouts
How financial discipline and the right systems (like Pentane) can drive smarter growth

If you’re an eCommerce founder or operator heading into Q4, this is the ultimate conversation about scaling sustainably — without losing yourself in the process.
