Description

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 identifies anonymous returning visitors and matches them to your first-party customer profiles inside the ESP you already use — Klaviyo, Mailchimp, SendGrid. No migration. No new tools. No rented third-party data. Then our ML engine activates the flows that drive retention revenue: cart abandonment, checkout abandonment, browse abandonment, and winback. Every email is personalized to your brand, timed to behavioral intent, and optimized continuously using RFM segmentation and cohort modeling. You don't manage any of it. Geysera runs white-glove — from setup through ongoing optimization — so your team stays focused on running the business. Here's where we're different. Every dollar we report is holdout-tested. Randomized control groups. Real incrementality measurement. Not inflated dashboards. Not phantom revenue. You see exactly what Geysera generated that wouldn't have happened without us. You set the guardrails — discount limits, free shipping rules, product exclusions. We optimize within them. And you only pay for proven results. If we don't generate incremental revenue, you don't pay. Identify. Recover. Prove.

Description

Stella is a platform designed for marketing measurement, providing marketers with robust, scientifically validated insights into which advertisements, campaigns, and media channels effectively contribute to increased revenue. The platform is equipped with three primary tools: Incrementality Testing, Always-On Incrementality, and Media Mix Modeling (MMM). Through Incrementality Testing, Stella conducts geo-holdout studies, also known as inverse holdouts, to evaluate performance differences between test and control areas, effectively isolating the causal effects of advertisements as opposed to relying solely on attribution methods. This tool simplifies complex statistical processes, including causal inference and confidence intervals, allowing users to understand the potential outcomes without a specific campaign, thus uncovering the genuine “lift” attributed to each advertisement. Furthermore, its Media Mix Modeling feature employs a unique Bayesian approach to dissect historical marketing expenditures and various external influences, such as seasonality and promotional events, to assess the contribution of each channel to overall sales effectively. By leveraging these advanced methodologies, Stella empowers marketers to make informed decisions based on accurate data analysis.
