Six Major Llc

Six Major, based in Austin, Texas, works exclusively with brands that sell on Amazon, positioning itself as an extension of a seller's in-house team rather than a conventional outside agency. The team is small (1-10 people), and accounts are handled directly by a co-founder rather than passed between junior staff. The agency describes itself as selective, choosing to onboard only brands it believes it can add measurable value to, and structures its engagement around profit growth rather than isolated metrics like revenue or ACOS. Services center on Amazon-specific PPC advertising, SEO, catalog and inventory management, alongside the broader capabilities listed on its site — SEO, content marketing, conversion optimization, email marketing and pay-per-click. Work is organized around a five-step onboarding process, biweekly strategy calls, and weekly written reports, with clients given live access to profit data through Sellerboard. Pricing is structured as either a minimal monthly retainer or a percentage of net profit, whichever is higher, tying the agency's fee to account performance. Contracts can be ended at any time, with a partial refund of service charges offered if a client is not satisfied. The agency states it reviews and adjusts its PPC strategy regularly rather than applying a fixed playbook across all accounts, and case studies referenced on the site describe outcomes such as profit growth, keyword ranking improvements, and early sales performance following product launches.
