Filter Capital Research
Investment Thesis
Filter Capital is a Mumbai-based growth-stage investment firm targeting technology-led businesses in India. Founded by Nitin Nayar and Sumit Sinha, two investors who spent years together at the India affiliate of Warburg Pincus building the firm's technology growth practice, Filter Capital positions itself explicitly as a "Growth Specialist." The thesis centers on partnering with the next generation of Indian entrepreneurs who seek outperformance through differentiated use of technology, at the inflection point where a company is moving from early traction toward industry leadership. The firm describes its capital as patient and intended to form enduring partnerships, leveraging deep global networks and a rigorous approach to governance to help founders build companies into durable institutions rather than chasing quick exits.
Sector Focus
Filter Capital targets two broad opportunity sets in India: (1) software and digital services companies expanding into regional and global markets, and (2) consumer, financial, and business services companies harnessing India's demographic scale. In practice this has translated into a portfolio spanning enterprise SaaS (Capillary Technologies, THB), fintech and supply chain finance (M1xchange), mobility and transportation technology (Chalo), logistics (Loadshare), and consumer D2C brands (R for Rabbit, Nua).
Stage Focus
Filter Capital is unambiguously a growth-stage investor, not an early-stage or seed fund. Observed check sizes across its disclosed portfolio investments range from roughly $10M (M1xchange) to $50M (Nua Series C, alongside Peak XV), with rounds typically labeled Series B, Series C, or extended Series D. The firm invests in companies that already have product-market fit and are scaling toward category leadership.
Check Size
Based on disclosed deal sizes, typical investment appears to be in the $10M-$50M range, though the firm's share of larger syndicated rounds (e.g., Capillary's $95M extended Series D) may represent a partial allocation rather than the full round size.
Lead Tendency
Filter Capital both leads and co-leads growth rounds. It led R for Rabbit's $27M Series B (co-led by 3one4 Capital) and its $10M investment in M1xchange, while participating alongside Peak XV (which led) in Nua's $50M Series C, and alongside Tiger Global (which led) in Loadshare's Series C.
Recent Activity
Filter Capital closed its inaugural fund at Rs. 800 crores (~$97M) in April 2024, with LPs including HDFC Fund of Funds, HDFC AMC, SIDBI, SRI Fund, Oister Global, DSP family office, Akash Prakash (Amansa Capital), and Harsh Jain (Dream11 CEO). Since then the fund has been actively deploying: a $10M investment in M1xchange (May 2025), a $27M Series B lead in R for Rabbit (August 2025), and most recently participation in Nua's $50M Series C alongside Peak XV (September 2026). Portfolio companies have also generated major liquidity and expansion news: Capillary Technologies completed a public listing (November 2025) and announced the acquisition of Mastercard's SessionM loyalty business for $20M (February 2026); M1xchange's Mynd Fintech subsidiary acquired C2FO India (July 2026).
Portfolio Highlights
Filter Capital's current core portfolio spans seven companies: Capillary Technologies (world's leading AI-powered omnichannel loyalty management platform, 400+ enterprise customers across 30+ countries, now publicly listed), Chalo (India's leading bus transport technology platform), Loadshare (asset-light last-mile logistics network across 200+ Indian cities), THB (Asia's leading enterprise healthcare SaaS company), M1xchange (India's leading RBI-licensed TReDS supply chain finance platform for MSMEs), R for Rabbit (leading digital-first baby products brand), and Nua (India's second-largest digital-first women's wellness brand, serving 3M+ women monthly).

Decision Process
Filter Capital operates as a partnership led by its two co-founders (Nitin Nayar and Sumit Sinha), supported by a Managing Director and Principal-level investment team - a classic small-partnership growth investing structure rather than a solo-GP or large investment-committee model.
Founder Preferences
The firm backs technical and operator founders building differentiated, technology-led businesses in India across software, consumer, fintech, and business services, generally at the point where the company has established product-market fit and is scaling toward regional or global category leadership.
Geographic Focus
India-exclusive. All disclosed portfolio companies and the firm's Mumbai headquarters reflect a singular focus on the Indian market, though portfolio companies like Capillary and THB serve enterprise customers internationally across 30+ countries.
