What Iontra does
Iontra is a fabless battery-charging technology company founded in 2013 and headquartered in Centennial/Denver, Colorado, with additional engineering centers in Plano and Dallas, Texas and Bangalore, India. The company's core offering is a proprietary Charge-Control Algorithm based on electrodynamics, which uses real-time current and voltage feedback to manage current density uniformity at electrode surfaces, preventing lithium plating, dendrite formation, and SEI growth during charging. The technology is chemistry-agnostic and is claimed to deliver 2-4x improvements in cycle life, charging speed, and cold-weather performance compared with conventional CC/CV charging, with claims validated by seven third-party studies from University of Michigan, UL Solutions, Novonix, and NREL.
Iontra monetizes through a mix of licensing its charge-control recipe (flashed onto application-specific MCUs or delivered as secured software), sales of its proprietary Iontic and Iontra Charge Control (ICC) microcontrollers, battery characterization services using its fourth-generation Phobos cycler platform, and product integration support with on-site validation. The company is transitioning from a software-only licensor to a vertically integrated fabless MCU supplier, with the industry's first integrated RISC-V charge control and fuel gauge microcontroller sampling in 2025 and entering production in 2026, funded by a $45 million Series C round that brought total capital raised to approximately $120.3 million.
Iontra sells primarily to enterprise OEMs across consumer devices (smartphones, wearables, hearables, AR/VR, power banks), commercial and industrial (power tools, floorcare, drones, energy storage), and automotive/e-mobility. The go-to-market is direct enterprise field sales, beginning with battery characterization and progressing through product integration and on-site validation. The company holds 207 patents and has accumulated over 10.25 million hours of cell cycling data, with leadership including CEO Jeff Granato (co-founder of Proterra) and multiple former Texas Instruments MCU executives.

Iontra product offering
Product offeringCore offering
Iontra provides a proprietary Charge-Control technology — an electrodynamics-based battery charging algorithm delivered as a customized charge recipe that is licensed and flashed onto application-specific microcontrollers. The offering prevents lithium plating and dendrite formation to deliver 2-4x improvements in cycle life, charge speed, and cold weather performance for OEM battery-powered products. Supporting offerings include the Iontic and ICC battery charger MCUs, the upcoming RISC-V integrated charge control and fuel gauge microcontroller, plus battery characterization and product integration services.
Product overview
Iontra's product portfolio centers on its proprietary Charge-Control Algorithm platform, a software technology delivered as a customized charge recipe flashed onto application-specific microcontrollers. Key hardware products include the Iontic MCU (Iontra's proprietary battery charger microcontroller) and the Iontra Charge Control MCU (ICC). The company also offers the Phobos fourth-generation cycling platform for battery characterization and validation. Series C funding in late 2024 ($45M, total $120.3M) is supporting the launch of the industry's first integrated RISC-V Charge Control and Fuel Gauge Microcontroller, with samples planned for 2025 and production in 2026. Services include battery characterization and cycling services, and product integration services with reference designs and software libraries. Applications span Consumer Devices (mobile phones, power banks, wearables, hearables, AR/VR), Commercial & Industrial (power tools, floorcare, drones, handheld computers, commercial energy storage systems), and Automotive (EVs, e-bikes, e-scooters, residential energy storage systems).
