Terms in this story

  • Startup: A startup is a young company built to find a new way of doing something and to grow fast, usually by serving many customers at little extra cost. India also has a legal definition for scheme benefits: under ten years old, turnover under ₹200 crore, and working on innovation or a scalable model.
  • Funding stage: Startups raise money in steps called funding stages: pre-seed, seed, Series A, B, C and later, ending in a listing or a sale. Each step is larger and asks for more proof. In India, Series A rounds run from a few million dollars to about $15 million, as of November 2026.
  • Seed round: Pre-seed and seed are the first money a startup raises from outside investors. The difference is how much has been built when the cheque arrives: pre-seed backs an idea or prototype, usually with a cheque under ₹5 crore, while seed backs an early product and runs from a few crore rupees to a few million dollars.
  • Angel investor: An angel investor is a wealthy individual who puts personal money into a very young startup, often before it has steady revenue, in return for shares. In India most angels write cheques from a few lakh to a few crore rupees, and as of November 2026 pooled angel funds may take money only from accredited investors.
