Our Story

Calibre is a small, bootstrapped team creating a performance monitoring platform to help our customers ship better, faster websites and applications.

We pride ourselves on building thoughtful, easy to use tools with less. Calibre has been profitable since day one. We don’t chase venture capital, arbitrary growth goals and wish for huge exits—we are firm believers in sustainable growth and are in it for the long haul. Our customers are our investors: we answer to them first and foremost.

We might be a four-person team, but our resilient platform reliably serves thousands of users and teams across the globe. We continuously strive to create a product we’d love to use—with friendly, humane support, privacy and consent at the forefront, and most importantly, delivering actionable advice and data to drive better user experience for all.
