WelComm sells the “so what” behind the specification
The San Diego agency speaks fluent engineering. Its business is turning complicated electronics into stories that the people buying them have a reason to read.
AmberSemi Left the Wall Socket for AI’s Hottest Seat - Right Under the Chip
The Dublin semiconductor startup paused its solid-state circuit-breaker push to chase a nastier bottleneck: moving enormous current into AI processors without wasting it across the motherboard.
The Pennsylvania Startup Betting That Silicon Still Has Room to Run
Everyone said the next leap in power electronics had to come from exotic materials. iDEAL Semiconductor bet it could wring more out of plain silicon - and now its chips are shipping from a Minnesota fab.
The Korean Startup Trying to Shrink the Grid's Heaviest Box
Crocus wants to replace the hundred-year-old iron transformer with a silicon one that thinks. Its bet: the same box that charges electric cars can also keep an AI data center from browning out.
The Company Under the Cloud
AI may live in the cloud, but the cloud lives on switchgear, drives and control systems. ABB is the century-old engineering company turning the digital economy's appetite for power into an industrial growth story.
The Tiny Box Behind Every Solar Panel Is Enphase's Big Bet
Enphase turned the least glamorous part of rooftop solar into a platform. Now its panel-level microinverters anchor a connected system for making, storing, using, and selling household power.
Evans Electric Pty Ltd
Evans Electric Pty Ltd is a Sydney-based electric machine developer founded by Paul Evans that designs high torque density axial flux induction motors, integrated eAxles, silicon-carbide motor controllers and electromechanical actuation systems for electric vehicles, aerospace propulsion, heavy equipment and industrial platforms. Its patented double-stator, single-rotor axial air-gap architecture aims to deliver the same performance as conventional motors in roughly a third of the volume.
Scalvy
Scalvy is an Austin-based power electronics company building a modular, software-defined platform called the Power Neuron that distributes power conversion and control to the edge of each battery pack instead of routing it through a single centralized block. The approach targets three power-hungry markets - AI data centers, grid-scale energy storage, and electric mobility - promising higher usable energy, ultra-high efficiency, and faster development cycles. Founded in 2022 by Mohamed Badawy, the company raised a $13.9M Series A in March 2026, bringing total funding to roughly $17M.
Halo Industries, Inc.
Halo Industries is a Santa Clara deep-tech company that uses lasers instead of diamond wire saws to slice silicon carbide crystal boules into wafers, the foundational substrate for high-voltage power electronics. Spun out of Stanford in 2014, its proprietary light-based process aims to eliminate kerf loss, cut defects, and slash water and energy use, giving more usable wafers from every expensive crystal. Backed by an $80M Series B, Halo is scaling SiC production for electric vehicles, grid infrastructure, renewables, and aerospace, and extending the same approach to silicon, sapphire, and diamond.
Heron Power
Heron Power is a Scotts Valley, California company building solid-state transformers - power electronics purpose-built for the modern electrical grid. Founded in 2025 by former Tesla powertrain and energy chief Drew Baglino, its flagship Heron Link converts medium-voltage electricity to usable low-voltage power in a modular, software-integrated package, replacing the century-old iron-core transformer. The company targets utility-scale solar, grid-scale batteries, and hyperscale AI data centers, and is building a 40-gigawatt US factory to meet a backlog of orders.
Frenetic
Frenetic is a Madrid-born deep-tech company building AI-powered software and a manufacturing service for custom magnetic components - the unglamorous transformers and inductors at the heart of every power supply, EV charger, and electrified machine. Their platform compresses what used to take months of trial-and-error into days of simulation, and ships physical samples in roughly a week.
