About
Proxxi started when BC Hydro put out a small RFP for a wearable that would keep workers away from energized equipment, and co-founder Richard Sim built a working prototype rather than a research report. The band measures the strength of the electric field around a worker and escalates from a low vibration to an audible alarm as they close in; the voltage range is set in software, so one band covers everything from a wall outlet to a 500kV line. Data syncs to a phone and up to a team dashboard, which is the part utilities did not have before — near misses have historically gone unreported. On the TechVancouver stage in 2018 Macdonald described widening the target from high-voltage utility crews to the far larger low- and no-voltage population in manufacturing, construction and healthcare. In 2020 Proxxi added Halo, a social-distancing band on the same radio hardware; Voltage remains the core product.
Backers
BC Hydro funded the original prototype; Proxxi went through Creative Destruction Lab. The Oct 2018 angel round was $700K with no investor names disclosed.
Quick answers
What does Proxxi do?
It makes Voltage, a wristband that senses electric fields and warns industrial workers before they contact energized equipment, plus a dashboard that records warnings and near misses for the employer.
Who founded Proxxi?
Campbell Macdonald and Richard Sim, who met at Vancouver Hack Space. Macdonald is CEO; Sim built the first prototype under a BC Hydro research grant.
Who uses Proxxi?
Utilities and electrical field-service companies. Schneider Electric, ABB and FieldCore are named on Proxxi's own site; TechCrunch's 2018 coverage also named GE, Con Edison, Exelon and Baker Hughes.
