About JJ Zhuang
JJ Zhuang is co-founder and CEO of Pretty Good AI, a San Francisco company that builds voice-first AI for clinics and applies AI to healthcare operations: patient access, staff shortages, and provider underutilization. Kevin Henrikson is his co-founder. Crunchbase lists his CEO role as starting in 2025.
He was Chief Architect at Instacart from 2018 to 2024, where he oversaw technology strategy and led the company's AI product and workforce productivity work. From 2014 to 2018 he was a Distinguished Engineer and held other leadership roles at Microsoft, leading Office 365 app technology.
Before Microsoft, he co-founded Acompli and was its CTO. Microsoft acquired the Acompli mobile app in 2014 and rebranded it as Outlook. Crunchbase also lists earlier Chief Architect roles at VMware and Yahoo!. He holds a B.S. from Shanghai Jiao Tong University. He is Lead Independent Director on the board of IBEX (NASDAQ: IBEX), where he chairs the Corporate Governance Committee.
Crunchbase lists one personal investment, one portfolio company, no lead investments and no exits. He is an occasional angel, not a high-volume one. His one confirmed angel deal is Champ AI. Founders who have worked with him on the operating side may find his experience scaling products and engineering teams more useful than his investing history.
Champ AI raised an $8.5M seed round, which the Lounge deals desk dates to 2026. Public posts say Redpoint Ventures led the round, with defy.vc, SV Angel, Max Mullen and JJ Zhuang also participating. Champ AI is a San Francisco company founded by former Instacart operations staff. It targets back-office enterprise AI work. The Lounge deals desk shows two entries for this round, dated May and June 2026. These appear to be the same round listed twice.
JJ has not published a thesis, preferred stage or check size, and none is stated here. His one known investment was a seed round alongside institutional investors. His own work centers on enterprise and healthcare AI, large-scale cloud and mobile products, and AI operations, and the Champ AI deal fits that pattern. His Crunchbase bio says he is passionate about mentoring the next generation of technology leaders. He is based in the San Francisco Bay Area.
