GuRu raises $15M Series A for developing products that can safely deliver electric power through the air for powering devices using millimeter-wave technology
Context & Ripple Effects
GuRu's $15M Series A is an early entry in what became a funded wireless-power-delivery arc: three years later, Reach Power raised a $30M Series B led by DCVC to transmit electricity over the air to IoT devices, confirming investor appetite for the same problem GuRu is attacking with millimeter waves rather than lower-frequency RF.
The approach sits alongside adjacent energy-harvesting plays — Wiliot's $30M Series B backed by AWS and Samsung built chips powered by ambient radio frequencies — so GuRu is betting that directed, higher-band power can go beyond trickle-charging tags and actually run devices.
First-order effects
- GuRu now has the capital to move from millimeter-wave research toward shippable over-the-air power products, entering direct competition with Reach Power for the same IoT-device customers.
Second-order effects
- Reach Power's larger Series B sets up a two-vendor race on transmission distance and safety claims, giving device makers negotiating leverage and pushing both companies toward reference designs that lock in early adopters.
Third-order effects
- If the funding pattern holds across GuRu, Reach Power, and ambient-RF players like Wiliot, battery-and-charger assumptions in small-device hardware design start to erode, making delivered power a specification buyers evaluate alongside connectivity.
The trend: Venture capital is assembling a wireless-power category spanning millimeter-wave beaming, directed RF, and ambient harvesting, aiming to cut cords and batteries out of device design.
