Open source fullstack monitoring platform

What is your company going to make? Please describe your product and what it does or will do.

We built highlight.io to capture and replay exactly what users experience on web apps, making it easy to detect performance slowdowns and reproduce bugs. Just add a few lines of code to your app, and our platform records user sessions with error tracking and notifications, so engineers can fix issues faster without guesswork.

Where do you live now, and where would the company be based after YC?

Jay lives in Seattle, WA, and Vadim works remotely. The company is based in Seattle and remains remote-friendly after YC.

Explain your decision regarding location.

We chose Seattle because that's where Jay is based and where we started building the product. Remote collaboration with Vadim works well, so the company remains distributed around that hub.
