- Nexterity is developing a remote-controlled, battery-powered robot that automates loosening and tightening bolts on bolted flange joints — the hard, dangerous part of pipefitting that drives many trade injuries.
- Lindsey Elliott, a former ExxonMobil engineer and planner, launched the startup after years of conversations with pipefitters across the U.S. and Canada, targeting the NPS2-to-NPS8 pipe range that accounts for roughly 80% of pipes by her count.
- The robot clamps around a pipe in two pieces, slides along the pipe, and loosens or tightens four bolts at a time, with multiple configurations built for different standard pipe sizes that each fit in a single Pelican case.
- Elliott said each unit is light enough to be carried by one worker, a design choice that supports treating the robot like rental construction equipment rather than a capital purchase.
- Nexterity was selected for the Startup Battlefield 200 at TechCrunch Disrupt, with Elliott citing the industry's labor shortage and pipefitters forced into 12-hour shifts for three months straight as the demand drivers.
Why it matters: Pipefitters cite a labor shortage and exhausting 12-hour, three-month stretches as their daily reality, and bolted flange work is the most injury-prone task they face. By making the robot Pelican-case portable and rental-priced, Nexterity positions itself to reach the dominant 2-to-8-inch pipe range that runs through water, wastewater, nuclear, mining, and petrochemical infrastructure.
