TL;DR
Voltair, a Winter 2026 YC startup based in San Francisco, builds drones that 'perch' on transmission lines to recharge, a design the company says enables effectively unlimited range. Since June the team says it has validated its core charging system on a live line, produced five flying prototypes and inspected roughly 2,000 poles, with power utilities targeted as the first customers.
What happened
Voltair, founded in 2025 and part of Y Combinator’s Winter 2026 batch, is developing unmanned aerial vehicles that land on overhead conductors to draw power and recharge in place. The company reports it validated its core charging technology on a power line starting in June, has built five flying prototypes and used its equipment to inspect about 2,000 utility poles. The founders include Ronan Nopp (CEO), who previously worked on drones tied to Air Force and DARPA projects and concluded that live-line perching was technically feasible; Hayden Gosch (CTO); Avi Gotskind (CGO); and Warren Weissbluth (COO). Voltair positions power utilities as the first market, arguing autonomous, self-charging drones can multiply inspection coverage and help detect maintenance issues before they cause outages or spark wildfires. The company also lists plans to expand inspection services to rail, road, telecom and real estate, and says insurance firms and grid traders are interested in the data product.
Why it matters
- On-wire recharging could remove the need for battery swaps, a barrier to fully autonomous, continuous drone operations.
- Increased inspection coverage may help utilities identify faults earlier, potentially reducing outages and wildfire risk.
- If operational at scale, the drones could provide a persistent data layer about physical infrastructure for utilities and other industries.
- Autonomous inspection at lower cost may change how utilities budget maintenance and interact with insurers and grid market participants.

Quick glossary
- Perching: A maneuver where a drone lands or grips onto a fixed structure to remain stationary, conserving energy or performing maintenance tasks.
- UAV (Unmanned Aerial Vehicle): An aircraft operated without a human pilot onboard, typically controlled remotely or autonomously.
- Transmission line charging: A method by which a device draws electrical power directly from overhead conductors or other energized infrastructure.
- Infrastructure inspection: The use of sensors, cameras and other tools to assess the condition of physical assets like poles, lines, tracks or buildings.
