Employees inside the Voyager building at Nvidia headquarters in Silicon ValleyBloomberg/Getty ImagesA version of this story originally appeared in the BI Tech Memo newsletter.Sign up for the weekly BI Tech Memo newsletter here.A new side project, Lunches.fyi, takes the AI tooling craze in a lighter direction, ranking tech companies not by market cap, but by cafeteria quality.It was built by coding prankster Riley Walz in about an hour using voice-dictated commands into OpenAI's Codex (a task he says might previously have taken 20+ hours).The site scrapes publicly available tech company menus and uses AI to categorize and score meals. Early results crowned Nvidia a surprise leader, serving everything from "truffle mushroom pizza" to leafy greens worthy of its stock performance.But the experiment also highlights a familiar truth: AI is only as good as the data it's built on.

Replit CEO Amjad Masad publicly questioned his company's low protein ranking, prompting Walz to uncover a bug: missing nutrition data that had defaulted to zero.Sorry for the protein slander! Some menus didn't have nutritional facts, so the script assumed there were 0 grams of protein in all of Replit's dishes. Just fixed.

The joys of vibe coding...— Riley Walz (@rtwlz) March 10, 2026 Fixing the error quickly changed the results. It's a small, fun project, but a sharp reminder: AI breaks without quality data.You can check out how tech companies rank, over that the website: Lunches.fyi.Sign up for BI's Tech Memo newsletter here.
