Eppo Is Now Part of Datadog!

I’m excited to announce that Eppo has been acquired by Datadog. This acquisition will drive learning velocity for all Eppo customers, equipping them to expand experimentation across their organizations. With visibility into how any design, product, or technology change impacts the customer experience, teams will be able to connect engineering work to business outcomes—breaking down silos and enabling a culture of velocity and accountability. 

There’s much more to come, but I wanted to start by sharing why we’ve taken this step. 

Eppo’s Approach

Eppo has always been about learning velocity, with a theory that the companies that learn the fastest, win. This principle is embodied by experiments, ranging from canary testing to A/B testing and automated solutions like bandits. The more experiments a company runs, the higher the company’s learning velocity tends to be.

But there’s nuance in how we entered the experimentation market. Eppo’s vision started from an opinionated take on which experimentation cultures were getting it right, where data-driven behaviors were actually driving business value instead of spinning statistical theater. Summarized, this led us to believe experimentation should be:

  • Broadly accessible
  • Highly trustworthy
  • Used across all important business levers

Experimentation vendors new and old were failing this test, whether due to outdated worldviews on data teams, a lack of support for critical testing use cases, or a lack of empathy for diverse company contexts. We felt that a modern approach to warehouse metrics, a UX approach rooted in bringing various skillsets together, and a focus on bringing the frontier of statistical methodology to the masses would solve these problems.

Why Datadog

Joining with Datadog offers three major opportunities to move the industry forward into the next era of experimentation and learning velocity. These opportunities are rooted in the same three principles.

First, we can accelerate Datadog’s movement to becoming more collaborative by making products that are broadly accessible. Datadog began with a focus on engineers, but it has made major strides with product and data teams with features like Product Analytics, Session Replay, and Data Observability. Eppo is excited to add to our DNA of PM-friendly UX, statistical rigor, and warehouse metric management to Datadog’s existing products.

Second, a combined Datadog and Eppo can make learnings highly trustworthy, with an added pinch of at the fastest speed. With our combined technology, we can strike the right balance of precision and latency. Experimentation needs the most precise data sourced from the warehouse, and it is okay to have higher latency to ensure even 1% impact readings are correct. Product analytics, however, benefit from fluid, real-time event data that can explore at the speed of curiosity. In this category, raw, uncleaned data is fine for detecting large 50% differences. Eppo is a market leader in warehouse-centric composable metrics, and Datadog’s bread and butter is real-time event processing.

Third, we can drive learning velocity across multiple high-value problems. For example, a cousin of the A/B test is the controlled feature rollout via canary testing. Datadog’s real-time observability with Eppo’s flags and stats engine means that a true end-to-end canary test solution will finally be on the market. Datadog’s AI observability with Eppo’s contextual bandits will allow AI teams to ensemble gen AI foundational models in a state of continuous testing and rebalancing. Stay tuned to learn what is possible with our combined technology, and how we might make multiple Datadog products more statistical.

And of course, Datadog’s scale means that we can drive experiment velocity across 30,000+ businesses across the world. We’ve already proven that Eppo can drive success at 20-person startups and Fortune 10s, from decades-old retail companies to explosive AI natives. This is an opportunity to set a new de facto standard of experimental building practices across the globe.

Positioned for Agentic Product Development

Eppo was founded in 2021, a time that feels like the Stone Age since gen AI models have become mainstream. As we wrote in our AI manifesto nearly two years ago, the process of deriving ideas, implementing ideas, and measuring idea success has been turbocharged. Eppo has benefited here, with thousands of AI-driven experiments running through Eppo servers each year.

As sci-fi as our AI manifesto felt at the time, our imagination still fell short in one respect. We originally envisioned a human-in-the-loop process of tech workers implementing faster, better. But with the rise of AI agents, it has become clear that some types of product development will become fully closed-loop. Instead of engineers bussing tickets through a queue, AI agents can identify an issue, find its root cause, and implement a fix. And with flags and experiments, the fixes can be safely rolled out with all appropriate metrics measured statistically. 

What Happens Next?

Eppo customers will continue to receive the same experience, support, and services. Users will still log in to Eppo, now branded as Eppo by Datadog.

We’ll be building a new vision for experiment-centric product development that combines Datadog’s expertise in observability with Eppo’s expertise in experimentation. We’ll be working closely with the Datadog teams building Product Analytics, Real User Monitoring, and Data Observability.

The goal is to drive learning velocity for our customers, based on the belief that the companies that learn the fastest tend to win. We can accelerate our vision by getting all ideas tested, shipped, and celebrated across Datadog’s 30,000+ customers.

A Leap Ahead with More to Come

Joining forces with Datadog is the quickest path to the future of product development, one that’s more resilient, scientific, and agentic. We’re excited to join a thriving Datadog product culture, and Eppo customers can immediately take advantage of a broader suite that includes Product Analytics, Session Replay, Data Observability, and Application Performance Monitoring. The Eppo team is committed to building as part of Datadog for years—stay tuned for much more to come!
