app push · Friday
Airship, founded in 2009 as Urban Airship and based in San Francisco, calls itself a mobile-first customer experience platform for enterprise brands. It covers app push, in-app, web push, email, SMS and mobile wallet, with holdout experiments and native surveys.
Releva is an autonomous sales agent for B2C stores. It sells on your site and in your app with search, recommendations and a catalog chat. It brings customers back on every channel, and builds ad audiences for Meta, Google and TikTok.
The difference is on the site. Airship sends the messages: we found no site search, recommendation engine or shopper chat in its documentation, its predictions cover churn and send time, and its audiences leave by CSV export. Releva sells on the site, predicts each shopper's next basket and syncs value-based audiences to Meta, Google and TikTok.
What changes in your store
Sells on your site, not only in messages
- Releva: personalized search as shoppers type, recommendations on every page and a chat that answers from your live catalog.
- Airship: app push, in-app, web push and web and app experiences. We found no site search, recommendation engine or shopper chat in its documentation.
Knows what each shopper buys next
- Releva: a documented next-basket prediction, one of 16 recommendation algorithms, fills product blocks on the site, in email and in push, with boost, bury, include and exclude rules.
- Airship: its predictions cover churn risk and send time. Messages show products from the triggering event or your own API. We found no product catalog or feed in its documentation.
Tells your ads who to find
- Releva: value-based audiences for Meta, Google and TikTok from the same profiles, with your own customers left out of retargeting.
- Airship: its documentation describes a CSV export for Facebook custom audiences and an export to LiveRamp. We found no direct audience sync to Meta, Google or TikTok.

Measured against a baseline, in your own orders
Every number Releva publishes was read in a store's own orders against a baseline: a controlled A/B test, a switch-off test or a before-and-after. None credits an order just because a message was received. In one of them, a Singapore womenswear brand on Shopify ran Releva's emails against a replica of its Klaviyo logic and saw 96% more revenue per recipient in week one. The case studies show each test with its period and comparison.
Your store gets the same test. It starts with 30 minutes with your store open. Then you install the agent on Shopify, Gomag or MerchantPro, or add the script to any web store, and pick the first job: search and recommendations on your site, or one flow next to your current tool. A holdout group is set automatically, and after 30 days you compare the orders. How it decides explains the holdout.
