Investment Philosophy (for firm)

  • Philosophy – To invest in early stage startups that bring to the table revolutionary ideas, solutions to problems that are difficult to crack and the ones expected to cause an impact in large markets. It believes in investing for a long term (roughly 8-10 years). They also prefer startups with co-founders which according to them indicates soundness from business point of view.


  • They usually prefer to invest in ventures with that are tech-led, i.e., businesses backed by code or intellectual property. They have an inclination for B2B businesses. They believe that building capital moats by themselves is a winning strategy.
  • They believe that just providing capital is not the whole and sole purpose of helping startups, apart from the capital reserves and co-investment partners, they strongly believe in connecting these investee companies with their distinctive formal platforms and engagements. These include services partners Constellation Blu and Constellation Talent, in-house resources across growth capital, market development, operational best practices and community. They deliver value through resources and on-demand mentoring and assistance as and when required.
  • They work very closely for the first few years with the founders. Then they elevate their focus to keep pace with the demands of their growth companies. (But, we also stick with, and support, our less successful ventures well beyond traditional venture norms dictated by power laws and portfolio concentration. We do this, not because power laws don’t apply to us, but because supporting and sticking by founders is second nature to them)

Analyst questions

  1. Do you think your investment philosophy has evolved since 2010, if yes, then what factors led to it?
  2. (Sanjay Nath) In an interview at the Global VC Summit you said, “In India global companies are willing to acquire Indian startups as opposed to 3-4 years ago when this didn’t happen as much”, what according to you has led to this shift?
  3. The philosophy section on the firm’s website talks about capital moats, can you elaborate on the same?    
  4. I came across several articles about some of Blume’s offshoot funds (I A & II A) that were created in order to prevent total stock ownership dilution, can you explain the strategy behind it and also some examples of how it has worked out so far?
