Problem
Shopify merchants running Meta, Google, TikTok, and email campaigns often rely on client‑side pixels that cannot reliably link clicks to purchases across devices. This results in low event match quality, inaccurate attribution, higher customer acquisition costs, and missed revenue from abandoned‑cart flows.
Solution
Upstack provides a server‑side tracking platform that captures ecommerce events, resolves cross‑device identities, and enriches the signals before sending them to ad networks and email platforms via their conversion APIs. By stitching together anonymous sessions into a persistent user profile, the platform boosts match quality to 90%+ and enables ad algorithms to optimize for actual buyers. Enriched data also feeds Klaviyo and similar tools, recovering abandoned‑cart revenue without changing existing flows. The service is deployed in under 20 minutes, requires no code changes, and delivers measurable improvements in ROAS, CAC, and flow volume within the first week.
Target Audience
Primary customers are DTC Shopify brands spending $50K–$5M per month on Meta, Google, TikTok, and email advertising, as well as agencies managing multiple client ad accounts.
