500 Startups closed its tenth deal in India, backing technology startup ZipDial. Paul Singh said the investment was higher than the typical $250,000 ( Rs 1.3 crore) the fund invests in early-stage companies but was under $500,000. Bangalore-based ZipDial, has developed a mobile-engagement platform, which is based on the distinctively Indian concept of a “missed call”. A consumer just needs to make a call to a unique ZipDial number a company provides and disconnect after a single ring to receive an SMS or a call with details that the company wishes to provide.
