Eppo is an experimentation platform built to run directly on your data warehouse.

Written by Reflective Data experts · updated Oct 5, 2026

It focuses on statistical rigour, with features like variance reduction, and uses your own warehouse metrics for analysis.

It suits data-centric teams that want experiments that are auditable and consistent with other reporting.

A kill switch is a feature flag that can instantly turn a feature off in production.

An experimentation program is the organisation, process and tooling that lets a company run experiments consistently.

The MDE is the smallest change your test is designed to reliably detect.

Effect size is the magnitude of a difference between variants, not just whether it exists.

Statistical power is the probability that a test detects a real effect of a given size.

Bayesian statistics expresses results as the probability that a variant is better, updated as data arrives.
