• 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.

• Unlimited experiments and seats, so nobody rations testing to save licence cost.
• Serious privacy posture with EU hosting and no data resale.
• Transparent, published pricing.

• 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.

• Client-side only — no server-side experimentation.
• No feature-flag capability.
• Smaller vendor with a modest ecosystem.

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

Mid-sized e-commerce teams that want unlimited client-side testing with clean privacy handling.
