A few years ago, when Nikhil Sama started recruiting top execs for Snaplion, his app-building startup, he first reached for his phone. To find “like-minded” engineers and programmers, he looked no further than where he had worked before. Sama hired Anikendra Das, an IIT Kharagpur engineer he had met during a stint at Rocket Internet, which had incubated online retailer Jabong. “I’d practically put together most of the team at Jabong and knew Das would be a good match,” says Sama. In the intervening years, Anikendra Das had unsuccessfully tried to start a social media site—but neither could care less. “I knew we both had the same vision, we were confident the expanding mobile network would give our venture a big boost,” says Das.
