About the company

Infinitum Electric designs and sells electric motors that use air core technology to deliver smaller, lighter, and more efficient motors for mobility and general-purpose applications. The air core design removes the heavy iron stator, while a printed circuit board (PCB) stator eliminates acoustic noise and torque ripple, resulting in higher power output relative to weight. The motors are intended for manufacturers and businesses that need robust, efficient propulsion for vehicles and industrial machinery, with the company selling directly to these B2B customers. Infinitum differentiates itself through its air core approach, reduced motor weight, quieter operation, and a collaborative, transparent culture that offers competitive benefits such as stock options. Its goal is to scale production and deployment of high-performance motors across a wide range of applications by partnering with manufacturers and advancing motor technology.

Simplify's Take

What believers are saying

  • March 2026 headcount reached 293, showing hiring momentum despite restructuring history.
  • June 2026 Aircore EC+ launch targets AI facilities needing cleaner power and higher uptime.
  • Riverstone said Q1 2026 revenue matched plan, with bookings and supply-program visibility improving.

What critics are saying

  • Riverstone backed a January 2026 working-capital bridge after liquidity constraints emerged.
  • Series F closed at $72.5 million mostly from existing investors, signaling limited new demand.
  • If customer-specific delays persist into 2026, Infinitum's runway and valuation face pressure.

What makes Infinitum unique

  • Patented air-core motors cut weight, noise, and torque ripple versus iron-core designs.
  • Aircore EC+ integrates active front end control, reducing harmonics for data centers.
  • Infinitum combines motor, fan, and drive into one HVAC platform.

Infinitum names ex-Span.IO finance chief Lakshmanan Venkatesan as CFO

Infinitum, an Austin, Texas, maker of electric motors and fan systems, has appointed Lakshmanan Venkatesan as chief financial officer. He will lead financial strategy, planning, operations, and investor relations. The company is expanding its product range and scaling manufacturing to meet demand from power-intensive industries. Venkatesan brings more than 25 years of financial leadership experience in the solar, power, and electrification sectors. He was previously chief financial officer at home electrification company Span.IO, where he helped manage multiple private capital raises. Earlier roles include vice president of finance at Solar Mosaic and senior director of fund operations at Spruce Finance. "His combination of strategic financial leadership and operational discipline will be valuable," said Ben Schuler, Infinitum's founder and chief executive officer.

The enhanced aircore EC+: reducing energy cost and complexity for cooling applications.

The enhanced aircore EC+: reducing energy cost and complexity for cooling applications. Infinitum launches the Aircore EC+, a next-generation motor system designed to enhance energy efficiency and reduce operational challenges in power-intensive facilities. * Tuesday, 23rd June 2026 Posted 3 days ago in by Katy Hill Infinitum has unveiled its latest motor system platform development, the Aircore EC+, designed for cooling applications in high-demand facilities. The system incorporates features intended to improve energy efficiency, reliability, and operational performance while reducing system complexity. Traditional variable frequency drives (VFDs) and standard electronically commutated (EC) fans can generate harmonics that may affect electrical performance and reduce the amount of available usable power. As facilities increasingly adopt artificial intelligence technologies and greater electrification, managing harmonic distortion has become an important consideration for maintaining operational efficiency and avoiding potential disruptions. The Aircore EC+ is designed to address these challenges by helping users optimise power availability and system performance while reducing costs and complexity. Key features include: * Integrated Active Front End (AFE) Technology: The Aircore EC+ incorporates AFE technology within the motor's VFD to reduce harmonics at the source. According to Infinitum, harmonic levels are maintained within IEEE 519 standards, supporting cleaner power flow without the need for additional filters or extra installation space. * Standard IP65 Enclosure: The enclosure is designed to provide protection against dust, dirt, and moisture, enabling operation in outdoor environments and damp conditions. * High Resistance Ground: This feature is intended to maintain normal operation during electrical ground faults, reducing the likelihood of equipment failure. The system also includes power-loss ride-through capability to support continued operation during such events. * Hybrid Ceramic Bearings: These bearings are designed to resist corrosion and do not conduct electricity, which can contribute to durability and operational efficiency in demanding applications. The Aircore EC+ is aimed at organisations seeking to improve uptime, power quality, and operational efficiency while accommodating increasing power demands without expanding existing infrastructure. The Aircore EC+ is currently available. Additional information, including specifications and application details, is available through the Aircore EC+ product pages. The launch of the Aircore EC+ expands Infinitum's motor system portfolio and provides an additional option for facilities seeking solutions to power quality and cooling system challenges.
