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

Spillmark is a web-based marketing analytics and experimentation product for Amazon sellers using Meta ads. It combines data from Amazon Seller Central, Amazon Ads, Meta, and optionally Shopify through account connections or report imports to analyze sales, costs, fees, ad spend, and channel profit. Sellers can design and run geographic holdout tests that pause Meta ads in selected regions, then compare Amazon sales to estimate advertising's incremental effect. Results include uncertainty ranges and explanations of the calculations, alongside dashboards, alerts, and records of test designs. Connected-account access is read-only; the product does not change campaigns without seller approval. Spillmark also provides an MCP server and REST API for assistants and scripts. Brand-level measurement and recommendations are in private beta. Starter includes one active holdout test and alerts; Growth includes unlimited tests, live account connections when available, and branded Amazon PPC tests.
