EcoTrends came to us with a sustainable products idea and zero ecommerce experience. In 18 months, they crossed $1.9M in lifetime revenue across Amazon and their own Shopify store.
We handled product research, sourcing from US suppliers, listing optimization, brand registry, and a full PPC strategy that kept ACOS under 12%. Their orders grew 188% month-over-month in their best quarter.
"We tried two other agencies before Quantix. Both took retainers and went silent. Quantix actually shows up — daily PPC adjustments, real account manager, real reports. ACOS dropped from 28% to 11% in 90 days."
"I had no eCommerce experience. Quantix walked me through it, set up my Walmart WFS store, sourced products, and now I'm doing $32K/month. Three months ago I knew nothing about this."
"Our Shopify brand had been stuck at $40K/mo for a year. Quantix rebuilt our funnel, fixed our ad accounts, set up Klaviyo flows. We crossed $130K/mo within 4 months. Best decision we made."
