Judgment Labs builds the infrastructure for evaluating and improving AI agents in production. As industries grow more reliant on autonomous systems, the demand for rigorous agent evaluation follows.
In under a year, co-founders Alex Shan, Andrew Li, and Joseph Camyre grew the team to 20, announced their $32M Series A in May 2026, with plans to reach 40 by the end of 2026.

The Problem
The overhead of hiring
Contrario partnered with Judgment Labs throughout their growth to find technical talent that could keep pace with the company. Every hire, regardless of function, had to be technically excellent in their craft. At Judgment Labs, that meant fluency across the specific demands of AI development, from post-training and data quality to prompt engineering.
The operational cost of recruiting compounded quickly for them. Coordinating outreach, tracking candidate status, scheduling assessments and interviews, and keeping all of it synchronized across an ATS takes meaningful time. For Judgment Labs, that time came directly out of engineering and leadership bandwidth.
What Judgment Labs needed was not just a sourcing partner. They also needed the recruiting process itself to be largely self-executing.
The Solution
Run recruiting with Rio Agent
Contrario introduced Rio, its AI recruiting copilot, as the operational backbone of the Judgment Labs hiring process. Rather than routing work through email threads or separate dashboards, Rio operates natively in Slack. Recruiting instructions are issued in plain language and Rio executes them.

"Rio helps us really narrow down our pipeline, make sure we never lose track of what is going on inside the process, and reflect on how to improve for the next set of candidates."
— Alex Shan, Co-Founder & CEO, Judgment Labs
Behind each instruction, Rio's agents are doing the substantive work: pulling candidate data, writing and sending outreach, updating pipeline stages, and notifying relevant team members. The recruiter and Alex's team remains in control of every decision, but the execution happens without them having to manage it.
A recruiter on Contrario’s platform identified Adithya Sairamachandran as a strong match for the Forward Deployed Engineer role based on his prior experience in applied AI and customer-facing technical environments. He completed Judgment Lab’s two-day challenge in six hours and spent the rest of his time fixing parts of their deployed process.
For Adithya, the process itself was streamlined and efficient. He reviewed a shortlist of relevant opportunities from Contrario’s network and moved to first-round interviews within days. The absence of a traditional application process was deliberate: high-quality candidates are not typically searching job boards, and the network is designed to reach them directly.

"The whole process, from first contact to joining Judgment, was incredibly streamlined and straightforward."
— Adithya Sairamachandran, Head of FDE, Judgment Labs
The impact
Judgment’s first FDE
Within his first month, Adithya had accumulated the kind of product and customer context that typically takes considerably long to build. He is active across the full scope of the forward deployed function: setting up tracing infrastructure in customer environments, shipping PRs, and serving as a direct technical resource for the companies using Judgment Labs' platform.
Contrario and Judgment Labs continue to partner together beyond hiring. Contrario uses Judgment Labs to recursively improve our own AI systems, including Rio. Adithya is directly involved in that work, helping Contrario assess and enhance the quality of the recruiting intelligence that placed him in the first place.
Growing alongside each other
Judgment Labs builds a stronger team because Contrario places it. Contrario builds better recruiting infrastructure because Judgment Labs evaluates it.
Contrario will continue to partner with Judgment Labs as they scale toward 40 people and beyond.

"When a team is really focused on understanding what makes people tick and fit at Judgment, things turn out really well. The Contrario team is one of the best."
