X Background
Career
Sun’s personal site describes eight years building Firebase at Google before becoming a generalist founder. It lists Newsjack as current work, Medialyst as a journalist-finding product, and PressPulse as a PR-opportunity listening product. He also publishes a newsletter about targeted outreach and growth for bootstrapped founders. His stated interest is building the whole business, including product, operations, marketing, and sales.[1]
Contributions
A repeatable public-relations workflow
Newsjack turns PR tasks into agent skills, including checking newsworthiness, finding story angles, editing headlines, assessing journalist fit, and tracking coverage. Its support matrix distinguishes one-off chat tasks from workflows needing a local agent, saved configuration, browser, or external data source.[3]
Research before outreach
Its research tools connect to Medialyst for live news search, journalist enrichment, and media-list work. Newsjack credits Sun and Carly Martinetti as contributors. Its command line installs reusable editorial procedures into supported agents and sets up company-specific monitoring.[3]
