We build the data supply chain for AI.

UltraCrawler crawls, cleans, and categorizes the open web, then licenses that data directly to AI companies. We handle the unglamorous, hard part — sourcing and structuring — so AI teams can focus on building models, not crawling infrastructure.

Our mission

Make high‑quality web data available to the AI industry, responsibly.

Every major AI model needs web‑scale data to train, fine‑tune, or ground its answers. Most AI companies either scrape it themselves — expensively and inconsistently — or go without. UltraCrawler exists to close that gap: we crawl broadly, license responsibly, and deliver data that's actually ready to use.

Every dataset we deliver is de‑duplicated, stripped of boilerplate, categorized by topic and quality, and traceable back to its source — so your team can trust what you're training on.

What we stand for

The principles behind every dataset

Quality over volume

We'd rather license 10,000 clean, well‑categorized pages than a million noisy ones.

Respect the source

We crawl within robots.txt and licensing terms, and work directly with publishers who choose to participate.

Freshness by default

Continuous re‑crawls keep licensed datasets current, not frozen at some past snapshot.

Transparent, not a black box

Every record we deliver is traceable back to its source URL, timestamp, and crawl version.

Our approach

How UltraCrawler was built

Starting point

A data sourcing problem, not a scraping one

AI teams were spending more on ad hoc scraping and cleanup than on modeling. UltraCrawler started as infrastructure to fix that at the source.

Core system

Renderer‑aware crawling at scale

We built a crawler that handles JavaScript‑heavy sites, de‑duplicates near‑identical pages, and understands site structure — not just link‑following.

Today

Licensed data, delivered directly to AI companies

UltraCrawler now delivers structured, categorized, quality‑scored web data straight into AI training and retrieval pipelines via API, bulk export, or custom feed.
