Helionis Labs Raises Pre-Seed Funding from Transition VC to Advance Thermal Management Technology

Helionis Labs, a deep-tech startup developing advanced thermal management solutions for high-power electronics, has raised an undisclosed pre-seed funding round from venture capital firm Transition VC, the company said.

The Bengaluru-based startup plans to use the fresh capital to strengthen its materials research and development efforts, expand its engineering team, complete product certifications and reliability testing, accelerate original equipment manufacturer (OEM) prototyping programs, and establish a pilot manufacturing facility.

Founded by materials scientist Tarun Jha, Helionis Labs is focused on addressing one of the most pressing challenges in modern electronics: heat management. As sectors such as electric vehicles (EVs), telecommunications infrastructure, industrial automation, and advanced lighting systems become increasingly power-dense, efficient thermal management has become critical to improving performance, reliability, and product lifespan.

The company is developing proprietary printable dielectric materials and an additive manufacturing process to produce high-performance Insulated Metal Substrates (IMS), a key component in thermal management for power electronics. According to the startup, its technology offers lower thermal resistance, thinner dielectric layers, and reduced manufacturing costs compared with conventional Metal Core Printed Circuit Boards (MCPCBs).

India's electronics manufacturing sector remains heavily reliant on imported thermal materials and substrate technologies, creating opportunities for domestic innovation in advanced materials and components.

“Heat is one of the biggest bottlenecks in modern electronics, from LED lighting to EV power systems and telecom infrastructure,” said Tarun Jha, Founder and CEO of Helionis Labs.

“At Helionis, we started from the materials level and rebuilt the thermal substrate stack around additive manufacturing and proprietary dielectric technology. Our goal is to build advanced thermal management products from India that can compete globally on both performance and cost,” he added.

The company is initially targeting applications in industrial and automotive lighting, horticultural systems, EV power electronics, telecom power supplies, and industrial power systems.

Transition VC said its investment reflects growing interest in technologies that strengthen India's domestic manufacturing capabilities while addressing critical supply chain dependencies.

“India builds LED lights, cars, and increasingly power electronics too, but one of the most critical layers inside them, the thermal dielectric, is still imported, mostly from China,” said Raiyaan Shingati, Co-founder and Managing Partner at Transition VC.

“Helionis changes that. They have brought the single hardest part of the substrate in-house, printing their own dielectric to deliver around 30 percent better thermal performance at a lower cost than conventional boards,” he said.

Shingati added that the technology has applications beyond lighting and could play a significant role in emerging sectors such as EV chargers, motor controllers, and next-generation wide-bandgap semiconductor power systems, where efficient heat dissipation is increasingly important.

The global insulated metal substrate market is currently dominated by international manufacturers including Henkel, Ventec International Group and Rogers Corporation. Most Indian manufacturers continue to depend on imported dielectric materials and thermal substrates.

Helionis Labs believes its competitive advantage lies in controlling both the dielectric material formulation and the manufacturing process, allowing it to optimise performance, scalability, and production costs while reducing reliance on imports.
