In a recent interview, the legendary Vinod Khosla estimated that 85 per cent of Indian start-ups are overvalued and will come to grief. He was being optimistic, and he knows it. As a long-term venture capitalist, Khosla is inured to operating in an industry where the strike rate is roughly 1:10. What that means is: one in ten businesses ends up recouping the investment poured into it. A trivial mental calculation shows that one successful business must generate returns of over 10:1 for the VC industry to survive. This high-risk-to-high-return ratio is hit often enough for VC (and its sibling, the private equity, or PE, industry) to stay in business. PE has a better strike rate than VC because PE targets companies further down the road to profitability. Even so, the PE strike rate is also low.
