Overview
Coresignal supplies the raw material for quantitative sourcing: billions of public web records covering companies, professionals and job postings, delivered as bulk datasets or APIs with regular refreshes. Data-driven funds use it to build proprietary sourcing models and momentum signals — headcount growth, hiring mix, founder job changes — instead of renting someone else's black-box scores.
