Summary
Christina Qi started a hedge fund, Domeyard, while still an undergraduate at MIT, according to the original profile. At its height, the fund traded about $7 billion in volume per day. A "really bad year in 2020" led to the fund's closure. Qi then co-founded Databento, where she serves as CEO, with the goal of becoming "the single source of truth for financial information," in her words.

Databento supplies market data to hedge funds and AI labs. The company now has 70,000 customers, including Nvidia and OpenAI. It raised $97 million in a Series B round in July, bringing its total disclosed funding to roughly $127 million. The valuation has not been made public. Earlier this year, head of quantitative analytics Lou Lindley disclosed that the company had reached eight-figure annual recurring revenue. Qi said revenue has grown "almost tenfold from a base well above single-digit millions," but she declined to share exact figures, citing the number of competitors in the industry.

Despite a customer base concentrated on Wall Street and in Silicon Valley, Qi lives and works in Utah, her home state. The company's 38 employees work remotely. Qi has described her path from growing up on food stamps to running a venture-backed data company as something that "does feel like the American dream to an extent," according to the original profile, which was also covered by Entrepreneur.
