Theia Ventures

Check you fit the thesis

• Read the portfolio page first. Every company is a technology business tied to energy, materials, industrial systems or manufacturing, often with AI as a tool. If you are a consumer or pure services company, this is probably not your fund.
• The homepage asks for founders with deep technical insight and first-hand problem understanding. Say in your first lines why you understand the problem better than others.

Use the route it publishes

• The Get in touch page invites pitches from anyone building a technology business in a new energy sector. Use the general inbox listed there.
• No deadline, open call or intake cycle is stated, so there is nothing to time your pitch against.

Before you send

• State your stage, your technology and what is proprietary about it. The fund says it backs proprietary technologies that shift industry economics.
• Explain the India angle. The fund says it is rooted in the Indian ecosystem with aspiration for worldwide impact.
• Read its Perspectives articles and podcasts so your note speaks to a sector it has already written about.

Theia Ventures is a venture fund based in Bengaluru. Its investing vehicle, Theia Ventures Fund I, is a Category II alternative investment fund registered with the Securities and Exchange Board of India. The fund says it invests in disruptive tech companies transforming energy and industrial systems, and that it is rooted in the Indian ecosystem with the aspiration to build companies with worldwide impact.

Who they back

The homepage lists six focus areas: foundational models, advanced materials, industrial decarbonization, AI enabled businesses, circular systems, and power and industrial systems. The portfolio shows what that means in practice. It includes a materials discovery platform that combines generative AI with physics-based simulation, an AI-driven biochar business that replaces coal in steel and heavy industry, an AI biomanufacturing platform, behind-the-meter battery storage for commercial and industrial sites, high-efficiency fans for building cooling, aerogel insulation manufacturing, a renewable energy planning and marketplace platform, and an electric vertical take-off and landing aircraft maker. This is hard technology aimed at industry, not consumer apps.

What they look for

The site names four traits. Founders with deep technical insight and first-hand problem understanding. Category creators who define markets by building foundational infrastructure. Proprietary technologies that meaningfully shift industry economics. And a link to India, with global ambition. Portfolio founders quoted on the site say the team went beyond the data room, meeting advisors, collaborators and prospective customers before investing, and helped refine strategy afterwards.

Stage

The fund does not state a stage, cheque size or fund size on its website. Its portfolio news headlines describe a pre-seed round led by Theia in EarthSync and a pre-seed round for VoltSeal, so early-stage deep tech with a working thesis is the range the evidence supports.

How to reach them

The Get in touch page says that if you are building a technology business in any new energy sector, you should reach out and submit your pitch. It lists a general inbox on the fund's own domain. The site does not publish a deadline, an open call or an application window, so treat this as a rolling, relationship-led route. The fund also publishes a Perspectives section of articles and a podcasts page, which are worth reading to understand how it thinks about a sector before you write.
