Build with us.

Write to us anyway

If you work on quant research, machine learning or trading systems and the way we think about markets resonates with you, we would like to hear from you.

Tell us what you have built, what you are curious about, and a link to your work.

What we value

• Evidence. You test ideas on data they were not built from, and you are glad when one fails early.
• Care with numbers. You check the instrument before you trust the measurement.
• Ownership. You see a problem through, from the first question to the system that runs every day.
