Investments
Companies and founders I have worked closely with at Rainmatter. Because we invest from Zerodha's balance sheet with no external LPs or fund-lifecycle pressure, we can back long-duration businesses across fintech, climate, healthcare, and Indian deeptech.
Portfolio Directory
Assetplus
↗Technology & compliance platform for mutual fund distributors.
Most Indian households beyond Tier-1 cities still rely on human intermediaries to invest. Assetplus equips independent distributors with digital execution and back-office scale.
Capitalmind
↗Quantitative portfolio management & public market research.
Deepak Shenoy and team built one of India's most trusted market research voices first, then compounded that trust into a disciplined PMS and asset management business.
Indiadatahub
↗Domestic macroeconomic, sectoral & corporate data terminal.
Institutional-grade Indian economic data was historically locked behind expensive foreign terminals. Indiadatahub makes granular domestic datasets accessible at a fraction of the cost.
M2P
↗Core banking, payments, and card issuance API infrastructure.
Modern banking products require flexible middleware on top of legacy bank cores. M2P became the default issuance and payments plumbing for banks and fintechs across Asia.
Mprofit
↗Multi-asset portfolio accounting & tax reporting software.
Built with capital discipline before raising institutional money, Mprofit solves the messy reality of multi-asset accounting, family office consolidation, and capital gains taxation in India.
Financialist
↗Conflict-free wealth advisory & goal-based financial planning.
Traditional wealth management is skewed by distribution commissions. Financialist focuses on unconflicted, lifecycle-based financial planning.
Akshayakalpa
↗Certified organic dairy & farm-level soil regeneration.
Shashi Kumar proved that fixing rural dairy unit economics—bringing farmers from subsistence to predictable monthly cash flows—is the only durable way to produce clean, antibiotic-free milk.
Green Worms
↗Decentralized waste management & circular material recovery.
Municipal waste economics fail without source segregation and local recovery loops. Green Worms builds financially self-sustaining waste infrastructure across coastal towns and islands.
Krop AI
↗Farm-gate crop grading & agricultural quality analytics.
Objective quality assaying at the mandi and farm gate removes pricing opacity for both growers and institutional buyers.
Matchlog
↗Inland container triangulation & freight optimization.
Import containers routinely return empty to ports while exporters pay for fresh haulage. Matchlog triangulates inland container flows to cut deadhead mileage, freight cost, and diesel burn.
Naxatra Labs
↗High-efficiency axial & radial flux electric motors.
India's EV transition relies heavily on imported drivetrains and rare-earth magnets. Naxatra designs and manufactures high-torque, high-efficiency electric motors domestically.
Neufin
↗Project finance & clean energy transition platform for industry.
Mid-market manufacturers want to decarbonize to lower power costs, but lack project-finance structuring. Neufin bridges industrial energy buyers with institutional debt and solar developers.
Ossus Bio
↗Microbial bioreactors producing green hydrogen from effluent.
Green hydrogen via electrolysis is power-hungry and expensive. Ossus uses electro-active microbes to extract process hydrogen directly from industrial wastewater streams on-site.
Solarsquare
↗Residential rooftop solar engineering, installation & financing.
Residential solar in India was fragmented across local contractors with inconsistent quality. Solarsquare standardized cyclone-safe engineering, installation speed, and financing for homeowners.
Two Brothers Organic Farms
↗Regenerative agriculture & farm-to-home food brand.
Satyajit and Ajinkya Hange built an integrated regenerative farm in Bhodani first, proving that soil health, indigenous seeds, and supply-chain ownership create an enduring consumer brand.
Voltseal
↗Cell-level thermal runaway barriers for EV battery packs.
Battery packs operating in 45°C Indian summers face severe thermal propagation risks. Voltseal's phase-change composite materials isolate cell failures before they cascade into fires.
Zerocircle
↗Seaweed-derived biodegradable packaging films & coatings.
Unlike PLA bioplastics that still require industrial composting, Zerocircle uses cultivated ocean seaweed to manufacture packaging films that dissolve harmlessly after use.
Adsys
↗Domestic medical diagnostic & clinical imaging hardware.
Imported diagnostic equipment prices smaller Indian hospitals out of basic care. Adsys engineers reliable diagnostic hardware locally to bring down per-test economics in Tier-2 and Tier-3 towns.
Arboreal
↗Enzymatic stevia extraction & natural sugar-reduction systems.
Cutting refined sugar in mass-market beverages fails when natural sweeteners leave a bitter aftertaste. Arboreal's formulation science solves taste parity for food manufacturers.
Blackfrog
↗Solid-state portable active cooling for last-mile vaccine transport.
Up to a quarter of vaccines degrade in the last mile when passive ice-boxes warm up or freeze vials. Blackfrog's Emvólio carrier maintains strict 2–8°C control on battery power.
Emoha
↗In-home geriatric care & emergency response infrastructure.
As urban nuclear families grow, elderly parents live alone without clinical coordination. Emoha combines 24/7 emergency dispatch with routine geriatric care at home.
Sukino
↗Out-of-hospital continuum care & inpatient rehabilitation centers.
Acute hospital beds are expensive and unsuited for post-stroke, ortho, or neurological recovery. Sukino operates dedicated step-down rehabilitation centers that lower recovery costs and readmissions.
SuperYou
↗Fermented yeast-protein snacks formulated for Indian palates.
Most Indian diets are heavily carbohydrate-skewed. SuperYou uses bio-fermented yeast protein to put clean protein into everyday snack formats without the chalkiness of whey.
The Whole Truth
↗Clean-label packaged foods with 100% ingredient transparency.
Shashank Mehta built a category-defining food company on a simple counter-positioned premise: print every single ingredient on the front of the pack and control manufacturing in-house.
Galaxeye
↗Multi-sensor earth-observation satellites fusing SAR and optical payloads.
Optical satellites are blinded by cloud cover and night, while radar (SAR) imagery is hard to interpret. Galaxeye's Drishti sensor fuses both on a single microsatellite platform.
Karban
↗Aerodynamic airflow & medical-grade air purification hardware.
Instead of selling three separate appliances for cooling, lighting, and air filtration, Karban engineered a single aerodynamic hardware unit built for Indian dust and room layouts.
Spacefields
↗Indigenous solid rocket propulsion & aerospike defense systems.
Sovereign defense and small-satellite launch cadence depend on domestic energetics and propulsion. Spacefields designs and hot-fires modular solid rocket motors and aerospike thrusters in India.
