Pawan Kumar Chandana, cofounder and chief executive of Skyroot Aerospace, which on Thursday became India’s first spacetech firm to enter the unicorn club, said global demand is expected to be a major revenue driver as most of its conversations are with US, Europe, and southeast Asian customers.He added that the company — which has a post-money valuation of $1.16 billion — had to “break the glass ceiling” while raising capital in a sector where revenues take years to materialise.“When a product and the revenue streams are few years away, it’s a very unique kind of fundraising one has to go through and it’s been very, very difficult. But once our Vikram-I launch happened (sub-orbital), there was a lot of interest as there was proven capability,” Chandana told ET in an interview today.The Hyderabad-based startup founded by two former ISRO scientists — Chandana and Naga Bharath Daka — is preparing for the orbital launch of its Vikram-1 rocket from Sriharikota within the next two weeks, when it gets an official launch window. The company said the mission will carry a mix of domestic and international payloads. Chandana said Skyroot’s focus is to meet the growing global demand for customised launches. Chandana has always described Skyroot as a “taxi for space” business, allowing customers to place satellites in customised orbits, inclinations, and altitudes based on their specific mission requirements, much like dropping a pin on a map.ETtech
