• Statistics engine is genuinely strong — sequential testing and CUPED are not marketing veneer.
• Flags, experiments and analytics in one system removes a whole class of integration work.
• Warehouse-native mode satisfies data-governance requirements.

• Automatic metric impact on every flag catches regressions nobody thought to measure.
• Guardrail alerts stop a bad rollout before it reaches everyone.
• Strong data-platform integrations.

• Event-based pricing can escalate sharply on high-volume products.
• Broad surface area means a real learning curve.
• Changed hands twice in under a year — OpenAI acqui-hired the founding team in September 2025, and Amplitude took over the product and brand in May 2026, so the roadmap is still settling.

• Post-acquisition roadmap now sits inside Harness's broader platform strategy.
• Requires meaningful event instrumentation before the impact analysis is useful.
• Opaque enterprise pricing.

Product teams that want experimentation and analytics to share one source of truth.

Teams that want every release measured, not just deliberate experiments.
