Web Data For Your AI Pipeline

Training corpora, RAG knowledge sources, fine-tuning datasets, and live feeds that keep your model's answers current — custom-collected from the public web and delivered pipeline-ready.

Models are only as good as their data, and the data your product needs usually isn't in a downloadable dataset — it's spread across thousands of live web pages that change daily. We build and operate the collection: you specify sources and fields, we deliver clean, deduplicated, structured data as JSON, Parquet, a database, or an API your pipeline reads directly.

One-off corpus builds for training and evaluation, or standing feeds that keep a RAG index and agents current. Engineering-grade delivery — schemas, provenance per record, change tracking — without hiring a data-collection team.

How it works

1. Tell us what data you need. Sources, fields, and how often — in plain language. No technical spec required.
2. Free review, written verdict in 3 business days. Feasibility, coverage, and a fixed price. We only take on work we can deliver.
3. We deliver, and keep delivering. CSV, Excel, JSON, database, or API. Fixed fee for builds, monthly for ongoing feeds — never hourly. 30-day exit, everything transfers.

Independently documented: a peer-reviewed study (Rummo et al. 2021, Int. J. Environ. Res. Public Health) credits Marquee Data with delivering its ~20,000-record web dataset in two weeks for under $3,000.
