Helping your company find 10x engineers.
About Saffron
Saffron allows companies to quickly evaluate how well software engineers use AI to code. The way engineers write code has fundamentally changed, but the way companies evaluate them hasn't. Saffron gives teams full visibility into how candidates use AI agents to build, debug, and ship real features on an actual codebase. Saffron was founded by Robert Chondro (formerly MIT and Jane Street), Jerry Yao (Stanford and Jane Street), and Kazuma Choji (Harvey Mudd, published in NeurIPS and ICML), and is backed by Y Combinator (P26) and Afore Capital.

we’re doing something dumb on purpose.
we’re doing something dumb on purpose. introducing the saffron tour: we fly out to 5 series A+ companies, embed for a week, design ai-native assessments on your codebase, run them on your candidates, and walk you through every result. zero cost. first five only. ⬇️

engineers cost $600k-$1M in total comp now. every CEO will soon be asking the same question: why am i paying this much when half my team uses Claude like an autocomplete and the other half ships with 100x efficiency?

Sierra just rebuilt their entire engineering interview from scratch. Every company still running leetcode is about to look very out of touch. The argument they published yesterday is one of the sharpest I’ve seen on the state of technical hiring in 2026: Traditional interviews were testing mechanics. Syntax, algorithms, framework trivia. That signal used to matter. With Codex and Claude Code, it doesn’t. The real skills now are scope, tradeoffs, judgment, and shipping. So they tore down their old process and rebuilt it: A 2-hour build session where the candidate ships something real with AI tools of their choice. Reviewers debate the product flows and technical judgment. The debrief shifts from “should we hire this person” to “where would this person thrive.” The framing is correct. The execution is excellent. And yet — Most companies that read this post will nod, get inspired, and chang
