Amazon

Amazon Prime is the template for retention-driven, cross-vertical memberships. DoorDash's DashPass, which scaled past 35M members, is framed as following the Prime playbook: focus on retention and satisfaction, then cross-sell across verticals.

Prime bundles shipping, streaming and other benefits into one paid membership. DashPass applies the same logic by extending one subscription across multiple delivery categories.

Amazon search shows how ad load quietly erodes user trust. Peter Sellis cites Amazon search showing 16 ads before the first result as a case of subtly eroding trust. He argues ad auctions should price in the trust being traded off, not only the bid.

Modern auctions already factor the organic value to the user into the bid, so advertisers pay more to reach people who may not want to be reached. In chat products, trust could replace organic value as that term, and maximizing it is likely correlated with retention and advertiser value. Quote: "how influenced I should be should essentially be how much trust I'm trading off"

Selling through Amazon brings reach but weakens subscription attach and exposes you to clones. Skylight sells on Amazon alongside its own site and retailers, but on Amazon it cannot auto-enable the subscription or discount the hardware, so attach is much lower than on skylight.com.

Chinese OEMs also cloned Skylight's UI and sold the copies on Amazon, which led Skylight to conclude that "neither hardware nor software are moats anymore" and that defensibility must come from network effects, partnerships and retail relationships. Being everywhere still drove higher overall growth, making post-purchase education more important in low-attach channels.
