Blume Ventures

Blume Ventures is India's largest homegrown early-stage venture firm, founded in 2010 by Karthik Reddy and Sanjay Nath and headquartered in Mumbai. It manages over $600 million in assets and is typically the first institutional cheque in its companies, partnering for 8–10 years. Blume has scaled deliberately across four funds: Fund I (2011–14, ₹100 Cr) wrote $200–300K pre-seed cheques; Fund II (2015–17, $60M) moved to $400–750K seed; Fund III (2018–20, $102M) ranged $750K–2.3M; and Fund IV (2021, ~$290M, its largest) writes core cheques of roughly $1–2 million, entering at seed to Pre-Series A. The firm has built one of India's strongest portfolios — unicorns and breakouts including Unacademy, Slice, Spinny, Purplle, smallcase, Servify, Locus, Classplus, LambdaTest, Pixxel, Battery Smart and Namma Yatri. Blume is known for being genuinely founder-first and for institutional thought leadership through its widely-read Indus Valley Annual Report. Its 60-member team across India and the US provides active support in talent, finance, legal and follow-on fundraising, and it maintains a roughly 2:1 reserve ratio to back winners through later rounds. For first-time and repeat founders alike, Blume is among the most trusted seed-stage partners in India.
