Kelvin6k Shark Tank India Episode Review
Kelvin6K appeared on Shark Tank India Season 5, Episode 33, with Chennai-based founders Dr. Pradeep Kumar Sundarraj, Dr. Ravi Kant Upadhyay, and Deepiga Sugumar seeking ₹1 Crore for 1.3% equity (₹76.92 Crore valuation) and successfully closed a deal for ₹1 Crore for 2.86% equity + 2.14% advisory equity (₹35 Crore valuation) with Shark Ritesh Agarwal after most Sharks stepped back though impressed by “Made in India” robotics.
The deep-tech Construction-as-a-Service (CaaS) startup utilizes proprietary mobile autonomous 3D printing technology through flagship ATOM robotic arm (printing 2-foot pillar in 20 minutes, entire education center in 15 days, 2,500 sq ft house in <30 days) and Builder Bot Mini for on-site deployment, manufacturing machines entirely in-house with multiple patents (India/US) using fly ash-based geopolymer “ink” (90% carbon emission reduction versus traditional cement) reducing construction timelines 60% and costs 30%, achieving EBITDA losses -₹39 lakh/-₹20 lakh in previous years with 3 monthly organic visitors requiring SEO overhaul. Sharks reacted cautiously to niche deep-tech nature and early financial stage though ultimately Ritesh bet on long-term infrastructure sector impact.
