From Shark Tank Crash to Y Combinator: How Vecros Built India’s First GPS-Free Autonomous Drone
Two years ago, a moment of technical failure on national television nearly grounded the ambitions of a young drone startup. During their pitch on Shark Tank India Season 3, the Vecros drone lost its orientation and crashed while demonstrating obstacle avoidance—an unforgettable moment that could have ended their entrepreneurial journey .
Fast forward to 2026, and the narrative has completely shifted. Vecros, an Andhra Pradesh-registered deep-tech startup building autonomous spatial AI drones, has been selected for the Y Combinator (YC) Startup School—one of the world’s most prestigious startup accelerators that has launched giants like Airbnb, Dropbox, and Stripe .
This remarkable turnaround, from a televised technical failure to global validation, offers powerful lessons in resilience, deep-tech innovation, and the growing international recognition of India’s capabilities in “Physical AI.”
The Shark Tank Moment: A Crash That Became a Catalyst
In 2024, founders Prem Sai (IIT Delhi alumnus) and Rajashree Deotalu (NIT Nagpur robotics expert) walked onto the Shark Tank India set with a bold vision: to build autonomous drones that could fly without GPS, pilots, or cloud connectivity .
The demo went wrong. When Anupam Mittal approached the drone to test its obstacle avoidance, the AI—trained for a specific orientation—lost its bearings. The drone crashed into a wall, leaving the founders disheartened and the sharks alarmed. Zomato’s Deepinder Goyal called it “dangerous,” and boAt’s Aman Gupta admitted it was “risky” .
But the founders didn’t walk away empty-handed.
Despite the crash, Aman Gupta saw potential in their ambition. The founders revealed they had previously rejected a ₹15 crore acquisition offer for 70% of the company—a fact that impressed Gupta. He offered ₹20 lakh for 1% equity (valuing the company at ₹20 crore) along with ₹90 lakh as debt at 10% interest over three years .
It was a deal built on faith in the founders’ vision, not on a flawless demo. As Gupta said, “Aapki innocence aapki strength hai” (Your innocence is your strength) .
