In 2018, Barr Moses was looking to start a company but wasn't sure which idea to pursue. She decided to work on three different startup ideas in parallel to see which one gained the most traction with customers.

One of those ideas was Monte Carlo, a solution to address the challenges around data reliability that Barr had experienced throughout her career— dealing with broken data products, wasted time, lost trust, and firefighting data quality issues. As Barr met with potential customers, it became clear that there was significant demand from technical leaders grappling with the consequences of data downtime across their organizations.

Today, Monte Carlo has successfully created a new category and firmly established itself as the end-to-end data observability platform for companies like Cisco, Fox, American Airlines, and more. Now, in the era of AI, the role of data quality has never been more critical.

In this episode of Spotlight On, Barr and Accel’s Steve Loughlin reflect on Monte Carlo’s unique origin story, explain “Hell Yeah Moments” as a company success metric, and dig into why they chose speed, focus, and customer impact as core values. Barr also peels the curtain back on why she decided to launch the company alongside an entirely new category—Data Observability—and the grit and determination it takes to build and sell a product that’s never been built or sold before. There’s no playbook for that, but Monte Carlo created its own.
