Forgive us, we’ve been gatekeeping.

Because one of our own just helped build something that could seriously change the game in biotech.

Meet Kayleigh Arabella, a brilliant alum from our HEX International Singapore program. Today, she’s part of the trailblazing team at QDX, where they’ve been quietly building something extraordinary: Walter, an AI assistant designed to streamline and supercharge drug discovery.

At QDX, the team recently achieved the world’s fastest and largest quantum chemistry simulations, breaking speed records by 1000x. But that wasn’t enough. Researchers were still losing time on repetitive in silico experiments.

So they created Walter.

Walter isn’t just a tool. He’s a digital colleague who:

• Reads scientific literature, maps pathways, and executes experiments
  
  
• Helps biologists, chemists, and even non-scientists, design small molecule hits in minutes
  
  
• Automates admin-heavy research tasks like extracting data from patents and quotes for compounds
  
  
• Compresses weeks of work into a single afternoon, with zero learning curve
  
  

Sure, Walter had a rocky start (he spoke only Spanish for a while), but under Kayleigh’s guidance, he evolved fast. Think of him like a curious young graduate, bright, awkward, but full of potential. And now? He’s ready for the world.

The QDX team has launched Rush, a cloud-based platform built on Walter’s infrastructure. It’s designed for researchers who want to get sharper, faster, and more focused without having to wrangle code or systems.

“For the first time in history, we’ve just been handed the technology required to automate all that background noise away.”
