Investor Profile: Think Investments — Thesis, Cheque Size & How to Apply

Think Investments is a San Francisco-based investment firm with an office in Mumbai, founded in 2013 by Shashin Shah, a former partner at Valiant Capital. It invests globally in public and private companies with a multi-year horizon, and it has built one of the more distinctive India portfolios among US-headquartered firms: concentrated, research-led and willing to buy in secondary transactions as well as primary rounds. For late-stage Indian founders, Think is a name that often appears just before an IPO, not at seed.

Investment thesis

Think's own description of its approach stresses creative primary research, technology-led early-stage businesses, high-quality management teams and businesses capable of high returns on invested capital. In practice, its India portfolio leans heavily towards scaled consumer and internet platforms rather than deep-tech moonshots.

Fund size, stage and cheque size

Think described itself in a 2025 company statement as a $3 billion investment firm. No single fund size or standard cheque range is published for its private investments, so its overall size is not publicly disclosed as a venture fund figure, and founders should not quote a standard Think cheque. Its deals illustrate the range of its flexibility instead: in November 2025 it bought PhysicsWallah shares worth ₹136.17 crore from 14 employees at ₹127 per share, ahead of the edtech company's IPO, and it later raised its stake further.

Notable portfolio

Think's India portfolio, as reported across company filings and news coverage, includes Swiggy, FirstCry, Urban Company, PharmEasy, Spinny, Meesho, Rapido and Dream11, alongside Chaayos, Clear, makeO, Star Health and the NSE. It also backed PhysicsWallah before its IPO and participated in a 2025 venture round for Mosaic Wellness, the digital health platform. The pattern is clear: category-leading consumer platforms with large Indian user bases, where Think's research edge is an understanding of the business model rather than a bet on an unproven market.

Partners and programmes

Shashin Shah founded the firm and leads its investment approach, drawing on prior experience at Valiant Capital and Blue Ridge Capital. Think describes its team as professionals with deep operating experience in emerging markets and global technology. No accelerator, founder programme, credits scheme or perks bundle is published by the firm, so founders should not approach Think expecting a structured programme. Its support is capital, research and a long holding period, exercised most visibly when it publicly opposed a take-private transaction for TaskUs in 2025 as a significant shareholder arguing for minority-shareholder value.

How to apply for funding

Think's official website is minimal and publishes no open pitch form or application portal, so there is no verified public route for cold applications. Founders should approach through the firm's website, thinkinvestments.com, or, far more realistically, through a warm introduction from an existing investor, a portfolio founder or an adviser who already knows the firm. Think is not a seed fund to cold-pitch: the credible entry point is a growth-stage company with proven unit economics, a clear path to sustained returns on capital, and a reason to want a research-driven, long-horizon shareholder.
