JJ Tang

JJ Tang is co-founder and CEO of Rootly, the AI-native on-call and incident-management platform he started with Quentin Rousseau after the two met at Instacart. Tang had led product work there while Rousseau was an early SRE; together they saw incident process break down as the company scaled.

Instacart scale and the incident scramble

YC materials describe Tang and Rousseau watching Instacart grow through rapid scale while responders jumped between Slack, paging, dashboards, and tribal runbooks. The inconsistency under pressure, not only the outages themselves, is what they set out to productize.

Rootly as Slack-native incident ops

As CEO of Rootly (YC S21) Tang raised a Series A led by Renegade Partners with Google Gradient Ventures and others. The product centers incident response, on-call, status pages, retros, and AI helpers inside Slack and Teams so teams spend less time on coordination busywork during an outage.
