Most DTC brands pick their channel first and figure out the economics later. Jon Blair, Founder of Free to Grow CFO and founding team member of Guardian Bikes, says that's why so many struggle to scale. Drawing on work with hundreds of e-commerce brands, he joins Renee Hartmann and Chris Baker to break down the three "games" every DTC brand is playing (apparel, durable goods and consumables), why each needs a different playbook for CAC, channels and inventory, and how to tell a durable brand from a temporary arbitrage. Plus: why niche brands with loyal fans win, and how to measure growth across Shopify and Amazon.

The easy days of e-commerce are over. Five years after the pandemic-era asset bubble, DTC brands can no longer ride cheap customer acquisition and institutional capital. They have to build real businesses. In this episode, Renee Hartmann and Chris Baker sit down with Jon Blair, Founder of Free to Grow CFO, to talk about what that actually takes.

Jon was on the founding team of Guardian Bikes, now a multi-hundred million dollar DTC-only brand, before launching Free to Grow CFO five years ago. His firm has around 30 e-commerce CFOs and accountants and works with about 50 brands at any time, helping them scale from roughly $10 million to $50 million and beyond. Having seen hundreds of brands succeed and fail, Jon has developed a framework for why some scale profitably and others don't.

At the heart of it is the idea that every brand is playing one of three "games": the apparel game, the durable goods (first-purchase dominant) game, and the high-LTV consumables game. Each has a different playbook for product expansion, CAC management and channel strategy. For durable goods brands, physical retail is where lifetime value finally shows up, because the retailer becomes the repeat buyer. For consumables, it's subscription and the LTV-to-CAC equation. For apparel, loyalty builds slowly over years, and excess inventory is the silent killer. Jon says 100% of the apparel brands his team audits have too much of it.

The conversation also covers why Amazon-first brands often struggle to move into DTC, how marketplace expansion complicates attribution and strains the balance sheet, and why blended cohort models across Shopify, Amazon and TikTok are essential for consumables brands. Jon shares how one client grew from $800K to $5 million a month using this approach.

Jon also introduces a key distinction: arbitrage versus durability. Some brands succeed by being early to a nascent product category or ad channel, like AppLovin, but those windows can close within 30 days. His advice: know which game you're playing, and if you're benefiting from an arbitrage, build durability proactively before it disappears.

Korea has just 51 million people and a GDP under 2 trillion dollars, yet it was the fifth-largest luxury market in the world in 2023 and continues to export culture, from beauty to fashion to retail experience, at a scale far beyond its size.

On this episode of Commerce Beyond Borders, Renee Hartmann and Chris Baker sit down with Dominika Kustosz-Lee, a Rethink Retail Top Expert for 2025 and 2026 with nearly two decades of experience across Korean e-commerce, luxury, and business development.

They dig into why Korean consumers move as one, how Olive Young became the infrastructure behind K-beauty's rise, why Seongsu is now known as Korea's pop-up capital, and what global brands consistently get wrong when they try to enter the market.
