Tribal-led briquettes, terahertz imaging, and EV chargers: How 5 Tamil Nadu ventures are redefining impact

In Tamil Nadu's growing ecosystem, a clear pattern is emerging: founders are starting not with abstract opportunities, but with concrete problems that they have experienced firsthand. These issues include invasive species threatening wildlife habitats, ineffective industrial inspection methods for non-metallic materials, unreliable electric vehicle charging infrastructure, life science graduates being unprepared for careers in biotechnology, and off-grid communities lacking access to reliable power.

These aren't pitches crafted for investor decks. They're solutions born from proximity to the problem. Five Tamil Nadu startups, each operating in vastly different sectors, demonstrate how impact-driven entrepreneurship translates technical capability into scalable businesses while addressing challenges that directly affect communities, industries, and ecosystems.

Turning invasive species into livelihoods: TAMS Tribal Green Fuels

Deep in Sathyamangalam's forests, an invasive plant called Lantana camara has been choking native vegetation and destroying wildlife habitats for years. It spreads aggressively, displaces indigenous species, and creates fire hazards. Forest departments have struggled to control it. Meanwhile, tribal communities living in and around these forests face limited livelihood opportunities.

TAMS Tribal Green Fuels, founded by a collective of tribal entrepreneurs including J Siruvadivel, M Balan, Kajji Aiyasamy, Maniyan Madevi, Bagyaraj Parvathi, Sivaraj Santhamani, and Ramanathan Sivarajah, saw an opportunity where others saw only a problem. The company converts Lantana camara into briquettes, providing an alternative fuel source while systematically removing the invasive species from forest land.

Within a year, TAMS has produced 550 tons of lantana briquettes, provided livelihoods to 350 tribal people, and cleared 30 hectares of forest that serve as habitat for elephants and tigers. The model is elegant: environmental restoration funds tribal employment, which in turn sustains forest health.

"Forest can be saved from invasive species only with the active participation of indigenous communities living in the forest," Balan M says. Siruvadivel adds, "Tribal enterprises are very few in India. We want to prove that as a tribe we will be able to run a private limited company and contribute to environmental protection."

With support from StartupTN, WWF India, and the Forest Department, TAMS is scaling operations to other highly infested areas while building a model where conservation and community welfare reinforce each other. The company represents a rare intersection: social enterprise, environmental restoration, and indigenous entrepreneurship operating as a commercially viable venture.

Seeing what others cannot: TeraLumen's terahertz revolution

Industrial inspection has long relied on methods optimized for metallic structures. But as industries shift toward composites, dielectrics, and ceramics, traditional non-destructive testing methods fail. Chennai-based TeraLumen Solutions, founded in 2019 by Jyotirmayee Dash, is solving this with terahertz technology combined with AI-driven analytics.

Terahertz waves occupy a unique position in the electromagnetic spectrum, allowing subsurface imaging without damaging components. TeraLumen's platform integrates terahertz imaging, machine learning, and real-time diagnostics to detect defects in aerospace, automotive, energy, and defense applications with micron-level precision for coating thickness measurement.

"From research to real-world reliability, we bridge the last mile of deep tech," Dash says.

TeraLumen is the first and only company in India to commercialize terahertz technology for aerospace, defense, and research institutes, earning ISO 13485/9001 certification. Beyond industrial applications, the company is developing TeraMargin, a device currently in clinical trials for detecting accurate cancer margins during breast and oral cancer surgeries.

Recognition from BIRAC, Pfizer's Indovation Grant, and placement in the top 12 of the Qualcomm Design India Challenge validate the technical approach. With Rs 10 lakh in grant support and investor connections from StartupTN, TeraLumen is scaling a technology few understood five years ago into a commercial reality, addressing critical gaps in both industrial safety and healthcare diagnostics.

Making EV charging intelligent: Plugzmart's energy ecosystem

India's EV charging infrastructure remains fragmented and unreliable. Imported hardware dominates, service networks are thin, and charging stations often fail when drivers need them most. Chennai-based Plugzmart, founded in 2019 by Vivek Samynathan and Raghavendra Ravichandran, is building indigenous EV charging solutions with integrated software for real-time control, analytics, and remote management.

Plugzmart's chargers feature smart load management, predictive diagnostics, and integration with the company's proprietary Energy OS, enabling efficient energy distribution and reduced downtime. What differentiates the company is its ARAI-certified controller technology, developed and manufactured entirely in India, making Plugzmart a true Make-in-India solution.

"At Plugzmart, we believe energy efficiency and EV adoption go hand in hand. Our goal is to create an ecosystem where smart technology drives sustainability for every household and vehicle on the road," Samynathan says.

The company has created employment for over 50 engineers and technicians while supporting more than 100 vendors across Tamil Nadu. Partnerships with Panasonic, Jio BP, and ISRO for hardware and software deployments demonstrate commercial traction. Having raised Rs 11.6 crore in funding, Plugzmart is targeting production of 1,000 chargers per month by 2026 while expanding its Energy OS platform for smart grid management and virtual power plant integration.

With support from StartupTN through funding, mentorship, and market access programs, Plugzmart is positioning Tamil Nadu as a hub for indigenous EV infrastructure technology, critical to the state's ambition of becoming India's EV capital.

Powering remote communities: Bhaskara's wind solution

Off-grid and remote sites across India face unreliable or nonexistent power access. Conventional small wind turbines perform poorly in low, turbulent winds typical of rural locations and are difficult to install in challenging terrain. Chennai-based Bhaskara Engineering Services, founded by Indhumathy Basker and Raju Govindharajan, manufactures rugged small wind turbines specifically engineered for these conditions.

Bhaskara's straight-bladed and helical turbine designs capture multi-directional gusts with lower vibration and noise. The company provides site-adapted mounting and logistics for difficult terrain, easy on-site installation, and local after-sales support, delivering higher energy yield and lower total cost of ownership than off-the-shelf alternatives.

"From hilltops to islands, our turbines turn natural winds into opportunity," Indhumathy says. The company has productized field-ready turbines, completed prototype validation with IIT Madras incubation, and generated commercial leads through TNGSS exhibitions and technical reviews with institutions like NIOT.

Building workforce-ready biotech talent: Bversity's hybrid model

Life science graduates often emerge from traditional universities theoretically trained but practically unprepared for modern biotech workflows. Companies spend months retraining new hires while graduates struggle to find meaningful roles. Chennai-based Bversity, founded in 2021 by Sudharsan Varadharajan, Raghul Jaganathan, Saiganesh V, and Godwin Immanuel, bridges this gap with a hybrid, industry-integrated education model.

Bversity's programs combine flexible online learning with hands-on labs, workshops, and immersive industry projects. The company's Neuron AI platform, India's first generative AI-powered personalized learning platform for life sciences, customizes learning paths based on individual skills, pace, and career goals.
