About

I'm Craig Li, a software engineer with 10 years of experience, now focused on building products at the intersection of AI and real operational workflows.

I'm the founder of Preflite, a pre-launch QA tool for paid social ads. Most teams have a strong process for making ads, but almost none have a process for the moment after production ends and before the campaign goes live. That gap is where campaigns quietly bleed out: the ad promises one offer, the landing page shows another; a risky claim slips through and gets the ad rejected; the video is the wrong spec. Preflite compares your ad against its landing page, flags claim and spec issues, and turns the findings into a revision brief before a Meta or TikTok campaign goes live. It flags, you decide. It never auto-approves.

Before Preflite, I spent years building production AI systems, most recently as a Senior AI Agent Research Expert at Li Auto, working on computer vision and agent workflows where upstream errors create expensive downstream cost. That is the same idea behind Preflite: catch the silent failure before the first dollar goes out.

Preflite is currently in beta. If you run paid social and own the quality bar on creative, I would love your honest read. Try it at preflite.info or reach out.
