About

88% of your website visitors leave without a trace. They browsed your products, read your pricing, explored your case studies — then vanished. That traffic isn't lost. You just can't see it yet. Geysera matches anonymous returning visitors to your first-party customer data — no rented audiences, no third-party data networks. Then our ML engine triggers behavioral email flows timed to the exact moment a visitor is engaged on your site: abandoned cart recovery, lead reactivation, product education, booking requests. Every dollar Geysera generates is holdout-tested. No inflated dashboards. No phantom revenue. You see exactly what's incremental — and pay only for what's proven. Other tools claim 100x ROI without a single holdout group. Geysera was built for retention and conversion from day one. eCommerce or B2B — we turn anonymous visitors into proven revenue.

About

Upstack Data is the #1 Most Reliable Ad Tracking Software For Shopify — a server-side tracking and identity resolution platform for brands running Meta, Google, and TikTok ads. It captures visitor and conversion events server-side rather than in the browser, reducing the data loss caused by ad blockers, iOS privacy restrictions, and cookie expiration. By resolving visitor identity across devices and sessions, Upstack enriches the data sent to ad platforms and Klaviyo — improving attribution accuracy, lowering customer acquisition costs, and recovering revenue from abandonment flows. Core capabilities: server-side Conversion API, cross-device identity resolution, multi-touch attribution, and Klaviyo abandonment recovery. Built for Shopify brands · Plans from $249/mo · 21-day free trial · 60-day money-back guarantee.
