NEW DELHI: India’s entrepreneurial environment resembles startup Mecca Silicon Valley in many ways, feels San Francisco-based Twitter’s chief executive officer Dick Costolo , in comments that will be seen as gratifying by the country’s emerging business ecosystem, coming as they do from the head of one of the 21st century’s most high profile firms.Drawing parallels between the Silicon Valley and India, Costolo told ET that business meetings in Silicon Valley have an air of informality and purposefulness wherein the content of discussions is more important than the formality of the conversation.“I get that same sense here. When you walk into a room here, it is less about the PowerPoint slides and more about ‘let’s just get right to what we need to talk about and do here’. And that’s exciting to me as it maps very directly to how Silicon Valley and San Francisco work,” he said in an exclusive interview.“I am a lot more enthusiastic about the entrepreneurial environment here now than when I was coming in. And I was already enthusiastic coming in,” added Costolo, 51, who has run the nine-year-old company for the past five years since taking the baton over from co-founder Evan Williams.Costolo is the first Twitter chief to visit India at a time of great excitement around entrepreneurship in the country.Not a day passes without reports of new, interesting startups setting up shop, funded by investors chasing ever increasing valuations.In this aspect too, India is quite similar to the Silicon Valley, where enterprises that would normally be considered as infants have very quickly gone on to command multi-billion dollar valuations from investors keen to not miss out on owning the next Google or Apple.Asked if there was an element of “irrational exuberance” creeping in, Costolo, who was an entrepreneur before he sold off his company to Google in 2007, said there appeared to be a disconnect between valuations in public and private markets.“I think the public market valuations seem to be fairly rational right now. The private market valuations now are obviously quite high in many cases. In some cases fair and in other cases eyebrow raising,” he said, adding that the same was true of India too.Narendra Modi, who has the second highest number of Twitter followers among the political leaders in the world, launched “Twitter Samvad”, a service aimed at boosting the nation’s e-governance plans by helping government bodies and leaders communicate directly with citizens on a daily basis via Tweets and SMS on their mobile devices.The service will entail a set of curated tweets that will be delivered from the government and leaders’ accounts to mobile users across the country. Costolo met the prime minister on Tuesday.Twitter, which has so far focused on growing its user base in India (it does not disclose how many it has), is now ready to give a big push to its advertisement business in the country. It has hitched its wagons to cricket, especially the ongoing World Cup and the upcoming IPL season, to draw advertisers to the platform. “We are at an inflection point with the kind of relationships we are building with advertisers here,” said Costolo.Twitter is not just chasing organic growth. In January this year, it made its first acquisition in India, buying Bengaluru based mobile marketing and analytics startup ZipDial
