sieve

Accurate data from messy, unstructured sources

Visit sieve

sieve is a data extraction service that turns websites, PDFs, filings, and other unstructured sources into structured data. It combines AI-led extraction with human expert review and consensus validation, then delivers the results ready to use through an API.

The workflow starts with AI locating relevant source documents and extracting requested fields, followed by review from human experts and consensus validation to reduce individual errors. The platform also offers an AI web scraping agent that can turn websites into clean data, including data returned through API responses rather than visible page content. It is designed for investment firms, engineers, and teams working with financial filings, ESG data, time-series reports, and other complex sources. Access is available through the API, and the site offers a free trial of the web scraping agent, with samples available by contacting the company.
