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

Stella is a marketing-measurement platform built to give marketers clear, scientifically sound insight into which ads, campaigns, and media channels actually drive incremental revenue. It includes three core tools; Incrementality Testing, Always-On Incrementality, and Media Mix Modeling (MMM). With Incrementality Testing, Stella runs geo-holdout studies (or inverse holdouts) to compare performance between test and control regions, isolating the causal impact of your ads rather than relying on attribution alone. It automatically handles complex statistical analyses (causal inference, confidence intervals, MAPE/R² checks), letting you see what would have happened without a campaign and therefore revealing the true “lift” generated by each ad. Its Media Mix Modeling tool uses a proprietary Bayesian MMM to decompose historical marketing spend and external factors (like seasonality, promotions, holidays, weather, etc.) to estimate each channel’s contribution to sales.
