Technology & quantitative trading

We are a technology and quantitative trading firm. We are building a system that provides liquidity and fixes market inefficiencies across markets. If you are curious, ambitious and care about the details, come build with us in the AI era. Join us.

What we do

We are building a system to win. This is how:

01

Observe

We watch how prices form and where liquidity sits, and find the inefficiencies.

02

Solve

We pick one, understand why it exists, and build the system that fixes it.

03

Scale

When it works, we make it bigger. More size, more markets, more venues.

04

Repeat

Then we go find the next one.

Team

Previously at Wall Street prop trading firms and Silicon Valley technology companies.

Offices

Offices in Shanghai and Hong Kong.

Volume

Billions of dollars in trading volume every day, across CEXs and DEXs. Top-ranked market maker.

Join us

We hire quantitative traders and developers. Most of us are both.

Titles matter less than the work. Everyone here writes code and works close to the market: research, trading systems, infrastructure.

Beyond that, what we look for is simple and rare: curiosity that doesn't wait for permission, ambition that wants to own the outcome, and the habit of checking the detail nobody asked about. In the AI era, what you know matters less than how fast you learn and how much you care.

If that's you, send us something you built and what you'd do differently now.
