Construction workers spend hours on their hands and knees snapping chalk lines to mark where walls, plumbing and utilities should go. It’s painstaking, back-breaking labor. And that’s how it’s been done for centuries.

Tessa Lau saw an opportunity — and built a robot that does it faster, safer, and with surgical precision.

In this episode of Fund/Build/Scale, the Dusty Robotics founder and CEO shares some of what she's learned about transitioning from a researcher to a deep tech founder, including:

How she turned past startup mistakes into a rigorous customer discovery process
The structured approach Dusty used to land its first paying customer
Why she says stealth mode is overrated — and how building in public gave them a head start
How “cool tech” can lead you astray if you’re not solving a real problem
Smart ways to pivot and iterate based on actual user feedback
What it takes to build a mission-driven team that scales with you

If you’re interested in robotics, deep tech, or why some concepts fall into the valley of death while others sail over it like a Red Bull stunt team — listen in.
