About

Quandl built a marketplace for financial, economic and alternative data — the obscure, untapped datasets that investors will pay for because nobody else has them. Co-founder Abraham Thomas told the TechTO stage in November 2017 that data had started behaving like a commodity, with companies exploring for it, refining it and trading it the way they trade oil or gold, and that an entire ecosystem of startups was forming at each stage of that value chain. Nasdaq acquired Quandl in December 2018 and folded it into its Global Information Services business alongside Analytics Hub. The Quandl brand was replaced by Nasdaq Data Link in 2021, and quandl.com API endpoints moved to data.nasdaq.com.
