Rubric AI recently launched!

Launch YC: Rubric AI

TL;DR: Rubric AI is building the human and computational layer that turns expert judgment into training signals for frontier models and agents. They believe that shaping the world's most consequential AI systems requires both purpose-built training environments and exceptional judgment.

Founded by Pragya Saboo

Pragya has spent the last decade building complex products from scratch and scaling them. She was a product lead at Oscar Health through their IPO, built computer vision software for operating rooms at Apella, grew a women's health startup to profitability, and drove new product lines at Asana.

The founding team brings deep domain expertise across healthcare, coding, and finance, along with years of experience building large-scale infrastructure. They have shipped in high-stakes domains and know how to build for the scale this problem demands.

The Problem

There are now over 10,000 vertical AI companies deploying in specialized domains. They all face the same problem: generalist models can't reliably handle high-stakes, judgment-heavy work. While AI agents look impressive in demos, they frequently fail at runtime by selecting the wrong tools, failing to verify steps, or lacking the ability to recover from errors. These companies need their agents to reason and execute like domain experts, but the infrastructure to make that happen doesn't exist.

The Solution

Rubric builds runtime reasoning infrastructure that turns expert judgment into training signals for frontier models and agents. They build purpose-built reasoning environments, curate expert-verified reasoning traces, and plug in at test time to guide agents on how to reason, when they select tools, how they verify intermediate steps, and when they must escalate to a human, turning generalist agents into domain specialists.
