Protege wants to feed AI the data the web never had.

The real bottleneck in AI has shifted from compute to data. Protege is building the licensed marketplace for the real-world kind.

What Protege Does

Public web data built the first generation of large AI models. Then the well ran dry. The open internet, as Protege's founders like to point out, represents only a small fraction of the world's usable data - the rest sits behind the walls of hospitals, media archives, recording studios and motion-capture stages, locked up by privacy law and intellectual property.

Protege is the company trying to open those doors without breaking them. It runs a two-sided data platform: on one side, owners of private, proprietary data; on the other, the AI labs and enterprises that need real-world data to train, fine-tune and evaluate their models. Protege licenses that data, curates it into AI-ready datasets, and layers on the unglamorous but essential machinery - de-identification, provenance tracking, rights preservation and compliance - that lets both sides say yes.

The pitch is that this middle layer is where AI's next leap actually lives. Bigger models help, but a model is only as good as what it eats. By aggregating access to billions of data points across healthcare, video, audio and physical motion, Protege positions itself as core infrastructure for a phase of AI development that has moved past scraping the web.

It is a New York company, founded in 2024, and it has moved quickly - from a stealth launch to roughly $65 million raised and a customer roster it says includes a majority of the industry's largest AI labs.

“AI's next leap wouldn't come from bigger models alone, but from access to better data.” Bobby Samuels, Co-Founder & CEO

The Problem It Solves

Three things gate AI progress: compute, models and data. The first two have armies of companies attacking them. The third - responsible access to real-world data - had no obvious owner. That gap is Protege's entire reason for existing.

The Wall

Scraping ran out

The public internet powered early progress, but modern models need real-world data from regulated environments that was never online to begin with.

The Mirage

Synthetic isn't enough

Synthetic data can approximate patterns but can't fully replicate the complexity of the real world and actual human behavior.

The Lockbox

Rights and privacy

The most valuable data - clinical, audiovisual, behavioral - is bound by consent, IP and compliance rules that make casual use impossible.

“Access to the right training data continues to be the biggest bottleneck to AI's progress.” Bobby Samuels, Co-Founder & CEO

Products & Services

Protege organizes its offering around the AI lifecycle - from the first pre-training run to the final benchmark - and around the industries where real-world data is richest.

Stage 01

Pre-Training

Massive, diverse real-world datasets across industries to train foundation models at scale.

Stage 02

Post-Training

Narrower datasets for supervised training and human feedback that align model behavior.

Stage 03

Fine-Tuning

Curated, domain-specific datasets that adapt general models to specialized use cases.

Stage 04

Evaluation & Benchmarks

Uncontaminated, real-world data for honest testing - including a benchmarking collaboration with Vals.ai.

Platform

DataLab

An analytics workspace for exploring and working with Protege's catalog of data.

Governance

Rights & Provenance

De-identification, consent tracking and provenance built into every dataset, not bolted on after.

The Data Catalog

Across four verticals, Protege has aggregated access to billions of data points. The scale is the story - and the moat.

Why It's Different

Plenty of companies label and annotate data. Fewer solve the harder problem: legally and ethically sourcing data that was never meant to leave its owner's hands.

Protege's differentiation is structural. Rather than scraping or generating data, it builds licensing relationships with the organizations that own it - and designs for privacy, governance and rights preservation from the start. That approach favors curated, use-case-specific datasets over raw bulk, and it lets data owners keep their rights while getting paid. Since its seed round, Protege says it has generated tens of millions of dollars in revenue for its data partners.

The team's pedigree reinforces the pitch. Co-founder Travis May previously co-founded LiveRamp and Datavant, both built on neutral data infrastructure in regulated markets. In that world, being the trusted, neutral party is the product.

Who Uses It

Model builders & data owners

Frontier AI labs and startups on the demand side - reportedly a majority of the industry's largest players - and 100+ hospitals, media libraries, audio owners and motion-capture studios on the supply side. Enterprise customers include Siemens Healthineers.

“Protege is like an internal partner for us, helping us dig into exactly what data we need for the specific problem we're trying to solve.” Mahesh Ranganath, Siemens Healthineers

Business Model & Market

How it makes money

A two-sided marketplace

AI builders license curated datasets; data owners are compensated through structured agreements that preserve their IP. Protege earns by facilitating governed access and by selling value-added services - curation, de-identification, benchmarks and analytics.

Where it fits

The neutral data layer

Protege aims to be the central platform for licensed, real-world data in AI - a market where, it argues, no dominant player yet exists. It sits alongside labeling firms and synthetic-data vendors but competes on sourcing real, regulated data responsibly.

Alternatives range from AI labs sourcing data in-house to data-labeling companies like Scale AI and Surge AI, marketplaces such as Defined.ai and Appen, and synthetic-data providers. Protege's wager is that none of them own the trusted, licensed, real-world layer - and that this layer is where the next decade of AI value accrues.
