Sigma Ventures

Day-to-day investment decisions sit with General Partners Kshitij Naik, Nilyanka Bhushan, and Dr. Murali Murti. Naik handles deal origination and scaling, Bhushan manages LP relationships and consumer-tech theses, and Murti leads technology evaluation for defense, enterprise SaaS, and logistics. The firm also relies on Head of Investment Advisory Sunil Nair, who co-led over 40 private-equity transactions deploying more than $2 billion in equity at Citi Venture Capital International, though his exact voting or committee authority is not disclosed on the firm’s website.

Sigma’s sourcing model leans on a network of senior advisors with decades of operating and government experience. Dr. S. Narayan, former Economic Advisor to Prime Minister Atal Bihari Vajpayee, provides access to regulatory and policy circles, while Vice Admiral Suresh Bangara (Retd) opens defense-procurement channels. Thomas Preising and Arun Seth bring global tech supply-chain and telecom relationships from Apple and British Telecom. The firm’s website positions this advisor bench as its primary origination engine, supplementing the General Partners’ own networks across Indian and European emerging markets.

Sigma’s website positions the firm exclusively as a direct investor in early-stage startups, with no mention of fund-of-fund commitments, LP stakes in other managers, or secondaries. The team page ties each General Partner and advisor to specific sector and stage coverage for direct investments, without referencing any indirect investment programs.
