How Findry compares to Amplitude Experiment.

Amplitude Experiment is your A/B testing infrastructure. Findry is the decision layer above it. They're complementary — Findry pulls Amplitude results into the closed loop.

Where it's strong

Amplitude Experiment

  • Industry-standard experiment framework with full statistical rigor (Sequential, Bayesian, multi-arm)
  • Tight loop with the Amplitude analytics platform — events, cohorts, funnels, retention
  • Feature-flag-driven rollout with targeting, audiences, and holdouts
  • Engineering-team friendly SDKs across web, mobile, and server
What it adds

Findry

  • Captures the hypothesis BEFORE the experiment runs — so you can tell what you actually believed
  • Links the experiment to the signals that prompted it — research, support tickets, anomalies
  • Records the bet's structured predicted impact and compares to Amplitude's actual result automatically
  • Stores the verdict + lesson as a Pulse-shareable, audit-ready chain — not just a dashboard

When to pick Amplitude Experiment

Pick Amplitude Experiment when you need the testing infrastructure — the SDKs, the targeting, the statistical engine, the rollout mechanics. It's the right tool for actually running the experiment. It just doesn't answer which experiments to run, or what they meant.

When to pick Findry

Pick Findry alongside Amplitude when you want the decision history. Findry captures the hypothesis, links the signals that prompted it, records the predicted impact, and turns Amplitude's result into a verdict your team can defend six months later. Best teams use both: Amplitude for the test, Findry for the decision.
