Time for difficult problems
Rainmatter is Zerodha's investment platform for Indian founders. It began in fintech and has expanded into health, climate, media and deeptech. It invests from Zerodha's own capital, with no outside LP fundraising cycle or forced exit timetable. Its current website gives an investment range of ₹50 lakh to ₹100 crore, says it does not take board seats or run portfolio businesses, and welcomes founders without a fixed stage requirement.
The August 2026 climate and deeptech investment note focuses on engineering-led manufacturing, bioenergy, storage, materials, quantum sensing and computing, space, autonomous machines, water and clean air. The portfolio also contains ordinary financial services, consumer brands and media. Those stay visible without being relabelled deeptech.
Zerodha announced an additional ₹1,000 crore perpetual allocation in August 2023. That is a dated commitment, not a current uninvested balance. The Rainmatter Foundation is the separate nonprofit side of the ecosystem. Its grants, and the website's $200 million foundation commitment, are not venture-fund LP subscriptions or additional investable capital counted here.

180 public investment relationships: 162 entries reconciled across all five manager categories, 17 additional companies in its August 2026 investment note, and the recently disclosed Axial Aero relationship. This is public coverage, not a claim about undisclosed investments or the legal cap table of one scheme.
GoldenPi and Trunativ keep the manager's acquired labels. Onco, Business Hero and Stoa keep its wound-down labels, even where an old company site remains reachable. A working site alone does not establish that an investment is still held. Quantum covers quantum sensing and photonic computing; Space Tech covers satellites and propulsion; Physical AI covers robotics, autonomy and device systems. Energy & Materials and BioTech follow the company's actual products, not the manager's original website category.
Most marks come from the manager's company records or the companies themselves. Carbon Masters, altM and Vecros use name labels where a suitable verified mark was not obtained. Where a company destination is unavailable or continuity is unclear, its link opens the manager record instead.
