About
Eppo is an enterprise-grade experimentation and feature management platform built on a warehouse-native architecture, now part of Datadog. It empowers every team — from data scientists and engineers to marketers and product managers — to run self-serve, statistically rigorous experiments without data silos or black boxes. At its core, Eppo offers full-stack A/B testing with a powerful statistical engine that supports advanced methods like CUPED++ to reduce experiment runtime. Its warehouse-native design means all data stays in your existing data warehouse, avoiding data egress, conflicting sources, and privacy concerns, while keeping infrastructure costs low. Eppo's feature flagging system handles billions of daily assignments with high availability, supporting feature gates, automated safe rollouts, kill switches, and dynamic configuration. The AI Personalization module leverages Contextual Bandits to automatically optimize user experiences in real time and get more value from AI models. For marketers, Eppo supports no-code website experiments, email/SMS campaign tests, and Geolift-based marketing incrementality measurement. Data teams benefit from centralized metric governance, versioned definitions, and automated diagnostics. Product managers gain experiment forecasts and slice-and-dice analysis without relying on the data team. Eppo also includes an AI Model Evaluation module, enabling teams to assess AI model performance against real business metrics rather than proxy metrics. It is ideal for growth-stage companies and enterprises looking to scale their experimentation culture.
Key Features
- Warehouse-Native A/B Testing: Run experiments directly on your data warehouse with zero data egress, eliminating black boxes and conflicting sources while maintaining full statistical rigor.
- Advanced Statistical Engine: Leverage methods like CUPED++ to reduce experiment runtime, automate analysis, and ensure trustworthy results across all team types.
- Fast & Resilient Feature Flagging: Power billions of daily assignments with feature gates, automated safe rollouts, kill switches, config flags, and A/B test flags in one unified system.
- AI Personalization with Contextual Bandits: Automatically optimize user experiences in real time using Contextual Bandits, or maximize the value of your existing AI models.
- AI Model Evaluation: Evaluate and compare AI models using trusted business metrics — not vanity metrics — so teams can build more effective AI-powered products.
Use Cases
- A product team runs A/B tests on new feature rollouts using Eppo's warehouse-native engine to measure impact on core business metrics like retention and revenue.
- An engineering team uses Eppo's feature flags to perform automated safe rollouts and kill-switch deployments across millions of users with zero downtime.
- A data science team centralizes metric definitions and experiment protocols in Eppo to ensure consistency and trust across all experiments organization-wide.
- A marketing team runs no-code incrementality tests (Geolift) on paid advertising campaigns to measure true revenue impact beyond click-through rates.
- An AI/ML team evaluates competing large language model configurations by running experiments in Eppo and measuring downstream business outcomes rather than offline benchmarks.
Pros
- Truly Warehouse-Native Architecture: All data stays in your own warehouse, ensuring no privacy risks, no data lock-in, and no conflicting metric definitions across teams.
- End-to-End Platform for All Teams: One tool covers A/B testing, feature flags, AI personalization, marketing incrementality, and AI model evaluation — reducing tool sprawl.
- Enterprise-Grade Statistical Rigor: Advanced methods like CUPED++ and automated diagnostics give data teams confidence in results and faster experiment cycles.
- Self-Serve for Non-Technical Teams: No-code experiment options and intuitive dashboards let marketers and PMs run and analyze experiments without waiting on data teams.
Cons
- Enterprise-Focused Pricing: Eppo is positioned as an enterprise tool with no publicized free tier, making it potentially inaccessible for small teams or early-stage startups.
- Requires Existing Data Warehouse: The warehouse-native architecture is a strength, but teams without an established data warehouse setup may face additional onboarding complexity.
- Demo-Required Sales Process: Pricing and access are not self-serve — prospects must request a demo, which adds friction for teams wanting to quickly evaluate the tool.
Frequently Asked Questions
What is Eppo and who acquired it?
Eppo is a next-generation experimentation and feature management platform that was acquired by Datadog. It enables trustworthy, warehouse-native A/B testing, feature flagging, and AI personalization for data, engineering, marketing, and product teams.
What does 'warehouse-native' mean in Eppo?
Warehouse-native means Eppo connects directly to your existing data warehouse (e.g., Snowflake, BigQuery, Redshift) without copying or egressing data. All metric computations happen inside your warehouse, preserving data governance and security.
Can non-technical teams like marketers use Eppo?
Yes. Eppo provides no-code experiment options for websites and email/SMS campaigns, as well as Geolift tests for measuring advertising incrementality, enabling marketers to run and analyze experiments independently.
What is Contextual Bandits in Eppo?
Contextual Bandits is Eppo's AI personalization feature that automatically optimizes user experiences in real time based on contextual signals, going beyond static A/B tests to dynamically serve the best-performing variant to each user.
How does Eppo help with AI model evaluation?
Eppo's AI Model Evaluation module lets teams run controlled experiments to compare AI model performance using real business metrics — such as revenue or retention — rather than proxy metrics, helping teams make data-driven model deployment decisions.
