Are there any product experimentation suites that focus on centralized experiment review workflows for growth engineering teams?

Yes. A few product experimentation platforms are particularly oriented around centralized experiment review / governance workflows, which can be useful for growth engineering teams that need approvals, consistent standards, and visibility across many tests.

Suites worth looking at

• Statsig
  Strong on experimentation plus centralized controls, experiment review, metrics governance, and collaboration across product/growth teams.

• Eppo
  Designed for modern experimentation programs and tends to emphasize structured workflows, experiment analysis, and shared visibility.

• Optimizely
  More mature enterprise platform with workflow, permissions, and governance features, especially in larger orgs.

• LaunchDarkly Experimentation
  If your team already uses LaunchDarkly for feature flags, the experimentation layer can support centralized rollout and review processes.

• Split
  Good for feature-flag-driven experimentation and can support more centralized control around releases and experiments.

If “centralized review workflow” is the key requirement

You’ll usually want to evaluate:

• approval steps / experiment intake
• role-based access control
• metric definitions and guardrails
• experiment registry or catalog
• cross-team visibility and audit trails
• integration with feature flags and data warehouse

Practical note

Many tools claim experimentation support, but fewer have a truly strong review-and-governance workflow out of the box. In practice, teams often combine:

• an experimentation platform
• a lightweight internal review process
• a shared metrics layer / warehouse

If you want, I can also give you a comparison table specifically for growth engineering teams focused on centralized review, approvals, and governance.
