Hey everyone — I'm Bob, co-founder of Geysera.

I built Geysera because I got tired of the same story playing out across e-commerce, B2B, and SaaS: you pay for a retention tool, it shows you impressive numbers on a dashboard, and you have no way to know if those conversions would have happened anyway.

That's phantom revenue. And the entire industry runs on it.

I kept asking a simple question: "Can you prove this revenue is incremental?" Nobody could. So I built a platform that answers that question by default.

Geysera identifies anonymous website visitors using first-party data (no sketchy third-party lists), activates ML-optimized email flows based on behavioral intent, and runs always-on holdout testing on everything. You see what's real and what isn't.

We're not trying to replace your ESP. We're the layer that recovers the 88% of visitors your current setup can't reach — and proves every dollar it generates.

If you're running an e-commerce brand, B2B company, or SaaS product and you've ever wondered whether your retention tools are actually working, I'd love for you to try Geysera. Happy to answer any questions here.
