Agency 6B × Amazon Sales at a Quarter of the Cost · September 2024 to June 2026
This is a founder-led health device brand that sells an at-home product through its own store, on Amazon and through clinics. Its customers are adults and the practitioners who treat them, and its founder runs the business. Agency 6B directed the price, the offers, the follow-up and every ad channel. From April to September 2025, Amazon brought in nearly four of every five paid sales, at about a quarter of the cost per sale on search.

The brand's founder brought in Agency 6B, a growth partner for founder-led businesses, in September 2024. The work ran until June 2026 and covered the ads on Amazon, search and social, the price, the offers behind them and the email that follows a first purchase.
Twice a month, the team met the client with one table: what each channel sold and what each sale cost. By spring 2025 that table had a clear answer. Amazon sold more, every month, for less.
Figures verified from the client's records across two or more tracking sources.
Amazon Won Every Month on Cost per Sale.
From April to September 2025, Amazon ads brought in 191 sales at about $55 each. Search brought in 54 at about $226 each.

Every Buyer Had a Way In.
A quiz, a book offer and a wholesale list gave buyers at different stages a next step. Email did the most with the visits that followed.
A Quiz for Practitioners' Audiences
Launched in August 2025. Ten responses came in during its first month, and the creative that led with relief performed best.
A Book for the Cost of Shipping
Gave buyers who weren't ready for the device a first purchase, and put the brand in their inbox.
A Wholesale List in the Store
Clinic buyers raised a hand and were sorted from consumers, so each group got its own follow-up.
