Carlos Cashman – Lessons from the Amazon Ecosystems – [Founder’s Field Guide, EP.15]
What this covers
Carlos Cashman, co-founder and co-CEO of Thrasio, discusses how the Amazon third-party seller ecosystem presents opportunities for a disciplined operator to acquire and improve underperforming small e-commerce businesses. The conversation ranges across Thrasio's founding origin, the structural challenges facing smaller sellers on Amazon, and the operational leverage available to a buyer with scale. Cashman draws on his earlier experience running a digital marketing agency to explain how recognizing the gap between value created and value captured led him toward owning businesses rather than servicing them.
The episode explores why customer acquisition capability—particularly in performance marketing on Facebook and Instagram—became a durable edge that most small Amazon sellers lack. Cashman traces how Amazon shifted from a marketplace into a performance marketing channel itself around 2016–2017, a shift that changed the competitive dynamics. The conversation also addresses how Thrasio's unusual path to profitability since founding in 2018 differs from typical high-growth company trajectories, and examines the broader ecosystem of acquisition terms and manufacturing commoditization that shape the economics of these businesses. Cashman reflects on hiring, delegation, and which elements of leadership cannot be outsourced—threads woven throughout his entrepreneurial history.
Cashman argues that the Amazon third-party seller ecosystem is full of profitable but under-managed small businesses, and that an operationally disciplined acquirer can buy and improve them to build a profitable high-growth roll-up.
- Strong customer-acquisition capability is a durable lever that small e-commerce sellers lack

Being exceptionally good at customer acquisition marketing on platforms like Facebook and Instagram is the key lever that drives e-commerce business growth, such that agency clients grew largely on the back of that capability while the agency itself only earned a fixed monthly fee rather than equity-like upside.
“Because we were so good at customer acquisition we had a lot of e-commerce businesses, and great ones. I was watching them all grow, and they were largely growing on what we were doing.”
An agency that drives its clients' growth but is compensated only with a monthly retainer fails to capture the equity-style value it creates, motivating the agency owner to seek a model where they own the underlying business rather than service it.
“They're super happy going out and getting $50 million, $100 million valuations, and we were getting paid our monthly check, which in some cases was nice and sizeable, but it was still just a monthly check.”
Thrasio, an acquirer of third-party Amazon sellers, has been profitable since its founding in 2018 and was most recently valued at more than $1 billion, an unusual profile for a high-growth company.
“In a surprising departure for a high growth company, Thrasio has been profitable since its founding in 2018 and was most recently valued at more than $1 billion.”
Around 2016-2017, Amazon began to be viewed not just as a marketplace but as another performance marketing medium that e-commerce operators could optimize alongside Facebook and Instagram.
“we were starting to mess around with Amazon potentially with some of our clients as another performance marketing medium, let's say in 2016 or so, 2017.”
