Move fast, ship smart: The engineering practices behind Statsig’s growth

Software Engineer, Statsig

At Statsig, we take pride not just in the products we build, but in the way we build them. While many tech companies emphasize innovation or speed, what matters most to us is our ability to consistently execute—to deliver results both quickly and reliably.

In a fast-paced environment where precision and speed are key to success, our engineering culture is a big driver of our rapid growth. Whether it's launching a new feature, fixing a bug, or evolving our platform to meet customer needs, we get it done—and we do it with focus, transparency, and efficiency. Here's how we move fast and ship smart.

(Real) Continuous integration and continuous deployment (CI/CD)

At Statsig, we've made continuous integration and deployment a reality. While some organizations claim to be "CI/CD-first," we go from code on a developer's machine to production in a single day—not weeks, not months. If a bug arises or a customer request comes in, we're able to address it immediately, push a fix, and verify the change within hours, not days.

Our fully automated CI/CD pipelines, combined with streamlined hotfix processes, ensure we’re always moving forward. Whether it’s a minor tweak or a major feature launch, our tools and processes make it easy to push changes safely, quickly, and with minimal friction. This means we react to customer feedback in real time and stay ahead in an ever-evolving landscape.

Meticulous prioritization

Rather than sticking to rigid sprint planning cycles, we take a more fluid approach to prioritization. Every engineer is empowered to assess the most important task at any given moment. The question we ask ourselves every day is: What is the most important thing I can be working on right now?

This ongoing conversation about priorities ensures we’re always focused on the highest-impact work, even if it means switching focus on the fly. With this model, we avoid bottlenecks and unnecessary delays, staying agile and responsive to both internal and external needs. It’s not about a perfectly planned roadmap—it’s about being ready to pivot quickly and tackle what’s needed in the moment.

Lots of project owners

One of the reasons we can stay so nimble is that engineers often drive projects themselves, without a lengthy triage process. This means no backlog of tasks waiting for a product manager to assign them. When an engineer spots an issue or sees an opportunity, they take ownership and run with it.

This autonomy fosters a sense of ownership and urgency across the team, empowering engineers to act and deliver features or fixes faster. By cutting out unnecessary layers of approval, we ensure progress keeps moving forward and nothing slips through the cracks.

Launching safely, not darkly

At Statsig, we believe in launching with confidence. We use feature flags to control how new features are rolled out, enabling safe and flexible deployments. Want to test a new onboarding flow or launch a seasonal update like a Christmas icon? With a click of a button, we can roll it out to specific customer segments, geographic regions, or a percentage of our users.

Feature flags allow us to deploy early and often, while minimizing risk. If something goes wrong, rolling back is just as simple. This approach ensures that we’re always iterating and improving while maintaining a stable experience for our users. It’s not about releasing in the dark—it’s about launching safely and intelligently, with full control over the rollout process. This allows us to land code now and ship it later. It also unlocks faster dogfooding of upcoming features, letting us ship them confidently sooner.

World-class leadership

Great teams need great leadership, and at Statsig, our leadership team’s commitment to transparency, trust, and growth plays a huge role in our success.

As an engineer at Statsig, I feel fully supported by my manager, leads, and CEO. We're aligned on company goals and kept in the loop on everything from growth metrics to strategic decisions. No one at Statsig is left in the dark about key business metrics, runway, or future direction—we get daily updates on how we’re doing.

Our leaders bring valuable experience, especially in fostering a culture of high performance. Emphasizing speed and iteration, our leaders draw from early experiences at companies like Facebook, where rapid execution was critical. As a result, we cultivate a culture of focus, productivity, and recognition, empowering engineers to do their best work.

Our core values: be scrappy

Being scrappy is in our DNA. When facing a problem, we don’t always look for the most complex or resource-intensive solution. Instead, we ask ourselves: Can we achieve this with less effort or fewer resources, without sacrificing quality?

Whether it’s building an internal tool to automate a task or finding a more cost-effective solution, we embrace creativity and efficiency. This “scrappy” mentality helps us move fast without over-engineering, while avoiding unnecessary technical debt. Our engineers and tech leads are experts at balancing smart architecture with simplicity, enabling us to scale effectively while maintaining stability.
