In this episode I speak to Christina Qi, founder and CEO of challenger market data provider Databento and former founder of HFT hedge fund Domeyard.

In our conversation, we discuss the challenges of starting an HFT hedge fund, how Databento differentiates itself in the market data space, how AI labs are using market data and the hazards of being based remotely in Utah.

As we mention in the episode, we will be on stage together at Quantvision on Thursday, and I will be at Eagle Alpha on Wednesday. I look forward to catching up with familiar faces in New York.

In this episode I speak to Evan Reich, a veteran of the alt data space who has worked at Millennium, SAC Capital, Quandl and most recently Verition in various data roles.

In our conversation Evan and I discuss a wide range of topics from how to hire a good data sourcer, to which data types are overrated, to whether exclusivity is a thing in the data market, to which jobs AI will erase first in our space.

In the podcast we mention Evan’s excellent conversation on Matei Zatreanu’s System2 podcast, which you should also check out if you like this one.
