As answered by people managing DocRaptor and Upstack Data.
Upstack Data's answer:
Upstack Data works with DTC Shopify brands including Perfect White Tee, Maelove, Labucq, Printfresh, Champo, Paire, Montreal Weights, and Aquarium Co-op.
Upstack Data's answer:
Upstack Data was founded by Michael Alt to solve a problem hurting Shopify brands: browser-based tracking quietly loses data to iOS restrictions, ad blockers, and cookie expiration, leaving ad platforms optimizing on incomplete information. By capturing conversion events server-side and resolving visitor identity across devices, Upstack Data gives Meta, Google, and Klaviyo the data they need to optimize for buyers, not browsers — helping brands drive 7- and 8-figure growth and recover millions in revenue.
Upstack Data's answer:
Upstack Data is built on server-side event capture through the Conversion API (CAPI), a cross-device identity resolution engine (Upstack ID), a multi-touch attribution model, and native Klaviyo integration for abandonment recovery.
Upstack Data's answer:
DTC Shopify brands running Meta, Google, and TikTok ads — typically those spending $50K–$5M per month on advertising who want to reduce the data loss caused by iOS restrictions, ad blockers, and cookie expiration.
Upstack Data's answer:
Most tools track anonymous actions. Upstack Data resolves the actual identity of visitors across browsers, devices, and sessions, then sends that enriched data to Meta, Google, and Klaviyo in a form they can act on — driving lower CAC, better attribution, and more recovered revenue. The result is a 90%+ Meta CAPI match rate, versus the ~35% typical of standard implementations.
Upstack Data's answer:
Upstack Data replaces a multi-tool stack — like Elevar plus Triple Whale — with a single server-side tracking and identity resolution platform, at a fraction of the cost. Setup takes about 30 minutes with no developer required, and every plan comes with a 10-day free trial and a 60-day money-back guarantee.
