After he's done with the big ecommerce war during Diwali season next month, Vijay Shekhar Sharma , founder of Alibaba-backed mobile commerce company Paytm , along with his son Vivaan and wife Mridula, will live in Bengaluru for a month. If the experiment goes well, the family will permanently shift to the city.“Bengaluru is to tech what Mumbai is for Bollywood — you must be there to create name in the film industry,” said Sharma. “It’s (Bengaluru is) the melting pot of all the top tech talent, they all come here like wannabe actors go to Mumbai for showcasing their talent,” he said.For Sharma, the triggers for shifting the base are twofold — on one hand Paytm is struggling to find great engineers in Delhi, and secondly, he wants his two and half year old son to grow in a more “middle class, grounded” environment.“I personally identify with the city’s grounded, middle class culture where people like Nandan (Niekani) and Azim Premji are the change agents,” he said.Sharma will join several other tech entrepreneurs, including Quikr founder Pranay Chulet , who have already moved to Bengaluru, home to India’s technology bellwether companies such as Infosys and Wipro, and a hotbed of top technology talent, similar to the Silicon Valley.On the one hand, some of the world’s biggest retailers such as Target, Walmart and Lowe’s are grooming technology talent for their global businesses in the city, and on the other hand, new-age startups like Flipkart, Ola and In-Mobi are using latest technology tools to scale their operations. All this has resulted in Bengaluru becoming the most sought-after talent market in the country.“We have around 700 engineers in Delhi, and we need couple of hundred more—but the “alpha engineers” we want are not found in Delhi,” said Sharma. Paytm, which competes with Flipkart, Snapdeal and Amazon, is realising that the technology battlefront is where it needs to maximise efforts.While Amazon brings its disruptive and innovative solutions from its headquarters to win more market share in India, Flipkart has started building a technology powerhouse led by two former Google engineering leaders—Punit Soni and Piyush Ranjan. Sharma, whose firm recently acquired a banking license from the RBI, said quality of ideas in Bengaluru are far superior too.“I was in a hall recently where Nandan asked the audience if incumbent banks could be disrupted by newer startups, and everybody raised their hands. This is the place where people believe they can change things, disrupt,” he said. It was Wipro founder Premji who suggested that Sharma move to Bengaluru at a dinner meet recently. Nilekani backed the idea.Archit Gupta, cofounder of online tax filing startup ClearTax , who moved to Bengaluru last month, said, “The ecosystem is much richer here, and I am not talking about engineering talent alone. Startups here have different complexity, and there’s availability of talent in the areas of digital marketing, etc.”
