About

• Strengthen founders with the right connections, pilots, and mentoring.

How We Help

EcoTN’s primary focus is on showcasing Tamil Nadu’s climate and sustainability startups to a wider audience. We promote selected startups in public forums through EcoHQ’s channels and share their visibility with private partners and stakeholders across our network.

By doing so, we aim to create opportunities for recognition, collaboration, and ecosystem support — whether that comes in the form of partnerships, programs, or investment fits.

Startups can apply to EcoTN by submitting their company profile and proof of startup incorporation in Tamil Nadu along with other details.

Call for Ecosystem Partnerships

EcoTN is not just about promoting startups — it’s about bridging the gaps across the entire climate and sustainability ecosystem. Here are some of the challenges we see, and where strong partnerships can make a difference:

• Corporates & Corporate VCs: Need entrepreneurs-in-residence, intrapreneurship programs, sandboxes to test innovations, and pathways for tie-ups, investments, M&A with startups.
• Incubators & Accelerators: Need a pipeline of strong startups, effective grant disbursement, and co-building centres of excellence with global universities for R&D, technology transfer, and commercialization.
• Startups: Often have promising technologies but lack product–market fit, defensibility, real-time market feedback, and access to paid pilots with corporates and governments to become investor-ready.
• Governments: Need credible players for project execution, pilots, and scalable solutions that align with policy and citizen needs.
• Investors: Seek pedigree startups with investable traction and clear defensibility in climate and sustainability markets.
• Family Offices, Banks & Corporate Foundations: Need curated, credible pathways to channel grants, debt, or catalytic capital into climate and sustainability ventures.

At EcoTN, our role is to highlight these gaps and bring the right players together. If you are an ecosystem partner who can support this mission — whether corporate, incubator, accelerator, investor, family office, bank, or foundation — we invite you to connect with us.
