Barchart Put Futures on the Web. Then Its Readers Asked to Borrow the Plumbing
A 1995 subscription site became a data supplier when customers asked to put its quotes on their own pages. Thirty years later, Barchart serves both the person checking a soybean chart and the grain elevator managing the hedge behind it.

Christina Qi is the CEO of Databento, an on-demand market-data platform for quants and asset managers, and a founding partner of Domeyard LP, one of the longest-running high-frequency trading hedge funds in the world. She started Domeyard from an MIT dorm room with $1,000 in savings, grew it to trade billions of dollars a day, then wound it down and built Databento to fix the broken market-data infrastructure that had frustrated her for a decade. A Forbes 30 Under 30 honoree, MIT trustee, and financial-literacy advocate, Qi turned a rough start into a career spent lowering the barriers to Wall Street for everyone else.
