Case Study: Fin Fun halves TACoS and regains ad control in 90 days with Teikametrics

Fin Fun Decreased TACoS from 6.8% to 3.4% in 90 Days

Fin Fun, a maker of fabric mermaid tails and an established Amazon 3P seller, was facing slowing US sales amid new off‑brand competition and waning consumer interest. After an ineffective engagement with a small consulting agency, Fin Fun turned to Teikametrics and its Managed Accelerator Program to gain algorithmic automation, best‑practice guidance, and greater control over their Amazon advertising.

Teikametrics conducted an account audit, restructured campaigns, kicked off automation, and provided hands‑on managed support and weekly performance reviews while training Fin Fun’s team. Over three months with Teikametrics, Fin Fun reduced TACoS from 9.2% to 4.6%, increased sales and profits, lowered reliance on paid advertising, and transitioned back to self‑service with the new campaign structure in place.
