What we build

Data programs, purpose-built

Six capabilities. One human infrastructure layer. From embodied AI to agent evals, we ship the gold-standard set your team can't assemble in-house.

Why Tbrain

Quality your team can't fake.

01

Lab-grade precision

Optical capture, IMU, and multi-camera rigs — not video-estimated approximations.

02

AI-native QC

Every sample runs through our confidence models before it reaches your training run.

03

Global expert network

Domain experts across science, engineering, language, and annotation tasks.

04

Custom programs

Scoped in days, first samples in weeks, SDK-ready exports.

Expert OS

A management system for agents and experts

Expert OS turns knowledge, evaluation, and workflow management into a product layer for teams running agentic AI programs at scale.

Explore Expert OS

Agent Knowledge Base

Custom one-to-one training and instant reference guides that keep agents aligned with the work they need to perform.

LLM-as-a-Judge

Automated evaluation before final human judgment, so quality scales without removing expert accountability.

Agentic Workflows

Workflow loops where agents help review, route, and improve agent outputs across the delivery system.

Agent Identity & Soul

Persistent agent context, goals, and operating style that make agent behavior coherent over time.

The network

Elite domain expertise, on demand.

When your model needs to learn from the best, we bring the best.
