Hey Hackers,

Welcome to another HackerNoon Company of the Week feature. Every week, we highlight a standout company from our Tech Company Database that's making waves in the global tech ecosystem and the lives of its users. Our database features everything from S&P giants to rising stars in the Startup scene.

This week, we shine the spotlight on Sonar, the company that has been setting the standard for automated code review for 17+ years by unifying code quality and security into one platform.

Rooted in open source, Sonar is trusted by 7M+ developers, including teams at Snowflake, Booking.com, Deutsche Bank, AstraZeneca, and Ford.

Get to Know Sonar

Sonar holds about 94% of the code-quality tools market, making it the clear leader in the space, not just another competitor.

Sonar's tools now run in over 400,000 organizations, built up over 17+ years of steady growth rather than a quick spike. Along the way, the company raised over $450 million in funding and hit a $4.7 billion valuation, backed by investors like Advent International and General Catalyst.

Heading into 2026, Sonar is focused on a new challenge: AI-written code. The company has been studying how much code developers now generate with AI and where that code tends to break or introduce security risks, positioning itself as the tool that checks AI's work, not just human code.
