Since its founding, Brex has rapidly established itself as a leader in modern finance, offering a global corporate card with integrated expense management, banking, bill pay, and travel software used by 30,000+ customers of all sizes from startups to enterprises. Over the past five years, Brex has expanded its offerings significantly, building robust data science, analytics, and engineering teams to support its ambitious growth and product development goals.

Finding the right experimentation platform

Before adopting Statsig, Brex relied on another platform for feature flagging and experimentation. However, the platform presented substantial challenges—particularly around experiment validation and data accuracy.

They found the complexity of validating user experiences, ensuring accurate exposure groups, and confirming data integrity incredibly frustrating, creating significant friction.

Seeking a more streamlined and reliable solution, Brex evaluated several platforms and found Statsig to be the ideal choice. Statsig’s seamless integration of feature flags, experimentation, and analytics—combined with an intuitive interface, dependable performance, and transparent pricing—directly addressed Brex’s previous pain points. They recognized that Statsig’s unified platform would effectively support their next stage of growth and evolving needs at scale.

“Every decision we make here at Brex is data-driven, but we constantly had to perform manual validations outside of our previous solution, which created massive inefficiency and even mistrust in our experiments.”

Empowering Brex’s data teams

Statsig quickly became integral to Brex’s data ecosystem, supporting distinct needs across multiple teams:

• Data Science Team: Responsible for employing advanced machine learning and causal inference techniques to guide strategic business decisions and automate internal processes. They leverage Statsig’s experimentation and analytics tools to test, validate, and optimize these data-driven strategies
• Data Analytics Team: Focused on building reliable, understandable reporting systems that serve as the source of truth for business performance, enabling stakeholders to make informed decisions. They utilize Statsig’s experimentation and analytics features to simplify validation and clearly communicate critical business metrics
• Data Engineering Team: Dedicated to developing robust data infrastructure that supports seamless integration and reliability across Brex. They were instrumental in setting up Statsig, leveraging its core data infrastructure and metrics catalog to streamline data flows and ensure efficient collaboration across teams

Brex continues to expand its usage of Statsig’s feature flags, experimentation capabilities, and analytics tools, embedding data-driven rigor directly into their product development and analysis workflows.

Growing adoption and expanding analytics usage

The simplicity and reliability of Statsig have fostered greater confidence and satisfaction among Brex’s engineering and data teams. This confidence has translated directly into a positive outlook on experimentation and increased experimentation velocity.

“Our engineers are significantly happier using Statsig. They no longer deal with uncertainty and debugging frustrations. There’s a noticeable shift in sentiment—experimentation has become something the team is genuinely excited about.”

Brex also recently expanded its partnership with Statsig by integrating the Product Analytics suite.

“The biggest benefit is having experimentation, feature flags, and analytics in one unified platform. It removes complexity and accelerates decision-making by enabling teams to quickly and deeply gather and act on insights without switching tools.”

The growing use of Statsig at Brex underscores their commitment to building a truly data-driven culture, streamlining workflows, and enhancing their product development velocity.

Unlocking efficiency and a culture of experimentation

Adopting Statsig delivered immediate, measurable impacts for Brex:

• Productivity gains: Brex’s data scientists experienced a 50% reduction in time spent on experiment setup and validation tasks, allowing them to focus on strategic, high-impact analysis
• Cost consolidation: Transitioning from multiple specialized platforms to Statsig resulted in over 20% cost savings, alongside reducing procurement and administrative overhead
• Accelerated experimentation: With Statsig’s ease of use and reliability, sentiment around experimentation at Brex shifted from negative to highly positive. Since adopting Statsig, the team has run over 100 experiments

Looking ahead

Statsig has become a foundational part of Brex’s data and product development stack—centralizing key workflows across experimentation, analytics, and feature management. As Brex continues to scale, the teams are not only running more experiments but also learning faster and making higher-confidence decisions, backed by trusted data.

Looking ahead, Brex plans to further expand its use of Statsig to power analytics workflows, accelerate experimentation velocity, and make product insights more accessible across the organization. With a single, reliable platform powering their data-driven product workflows, Brex is well-positioned to accelerate innovation while maintaining the rigor and speed required to lead in a competitive market.
