How Feel Goods Cross-Sells Their Wellness Line with Smart Cart

Feel Goods makes nutritionist-formulated drink mixes. Their catalog covers immunity, gut support, hydration, and flavor-set bundles, with formats ranging from 15-packs to 90-serving tubs. Every product in the line complements the others. Someone buying Immunity Icon™ is a natural candidate for Gut Guardian™ or one of the hydration mixes.
That cross-sell potential only works if the cart can act on it. A customer who adds one SKU should see the rest of the line right there, with a clear reason to add more.
Before Boost, the Feel Goods team cycled through multiple cart apps. None gave them enough control over how the cart looked and behaved, and performance dropped when running alongside their other Shopify apps.
"We've used many cart apps in the past, but none have the customizability or performance compared to Boost."

AI cross-sells across a complementary product line
Boost's Smart Cart uses AI recommendations to surface the right product at the right moment. When a customer adds Immunity Icon™, the cart recommends Gut Guardian™, Hydration Hero, HydraSip, or a flavor set bundle. The reward bar tracks progress toward free shipping or a discount tier, and shoppers see what they need to spend to hit the next one.
Feel Goods doesn't sell one hero product. They sell five drink mixes that work as a system, plus bundles for customers ready to commit. Boost's cross-sell engine turns that catalog structure into real cart behavior.
Custom integrations for their app stack
Feel Goods runs other apps on their Shopify store, and previous cart solutions created conflicts. Boost's team wrote custom integration code for Feel Goods' specific setup so the cart works cleanly alongside everything else.
"It's super easy to set up and the team has even implemented some custom features for our store to make it compatible with our other apps. Highly recommend!"

Boost charges flat pricing rather than a percentage of revenue. Custom integrations come as part of the service.
