Case Study: Souper Cubes achieves significant first-year Amazon growth with Perpetua

How AI-Optimized Amazon ads helped Souper Cubes® Achieve Significant first year Growth

Souper Cubes, founded by Jake Sendowski and Michelle Strausman, is a purpose-driven startup that launched an innovative kitchen product on Amazon with no prior digital marketing experience. Faced with limited time (both founders work full-time) and a need for clear ad attribution and fast go-to-market support, Souper Cubes sought a partner to handle Amazon advertising so they could focus on product and organic growth.

Perpetua managed and optimized their Amazon ads—using Perpetua’s Ad Engine, keyword and ASIN harvesting, and campaign execution—to drive targeted traffic and protect the brand. The results included faster-than-expected sales (they forecasted 3–4 trays/day but reached about 10/day within weeks), a product page conversion near 20%, successful brand defense in search, and new retail distribution (Sur La Table and 121 stores); importantly, Perpetua freed the founders’ time to grow the business organically.
