“Kai Deshon Se Proposals Mil Rahe”: Chennai Entrepreneurs Transform Construction with Automation
Three points you will get to know in this article:
1. How Kelvin6K secured a ₹1 crore deal from Shark Ritesh Agarwal on Shark Tank India 5
2. How Kelvin6K’s ATOM robotic arm is transforming India’s construction industry
3. Kelvin6K’s financial growth, future expansion plans, and its bold vision
Shark Tank India 5: Pitchers’ Dream from India to Moon and Mars
In Shark Tank India 5, the deep-tech startup Kelvin6k from Chennai made an exciting pitch. Dr. Pradeepkumar Sundarraj and Dr. Ravi Kant Upadhyay, the founders, presented their mobile robotic arm (the Kelvin6k ATOM), capable of on-site structure construction through 3D printing.
The novel approach instantly drew the interest of investors and audiences alike.
During their pitch, the founders spoke about their ambitious goals.
They said, “Aaj humein kai deshon se business proposals bhi mil rahe hain, lekin humare sapne to chhote chaand ke paar jaane ke hain. 2030 tak humara target hai Moon aur Mars par 3D print karna.
Hum dekh rahe hain ki future India ke liye aur duniya ke liye kya possibilities hain.”
They also explained the technology’s flexibility and eco-friendly design and added, “Solar energy ka use karke, sand aur other materials se ek big set bana kar, usse align karke hum destination habitat create kar sakte hain bina cement ya kisi aur traditional material ke.
Demo mein aapko dikhaana chahiye ki ghar yahan par kaise banega. Ek pillar build karenge, aur agar accelerator use karein to 10-20 minutes mein 2 feet ka structure print kiya ja sakta hai.
Installation mein aap few steps follow karke same result achieve kar sakte hain.”

How Kelvin6k’s ATOM Is Transforming India’s Construction Industry
The ATOM developed by Kelvin6k can significantly lower both the expenses and duration involved in construction. According to the founders, a 2,500 sq. ft. house can be printed in less than 30 days, reducing timelines by 60% and costs by 30%. Kelvin6k tackles delays and quality problems typical of traditional construction by substituting manual labor with precise robotics.
Another highlight is environmental sustainability. The startup employs a fly ash-based geopolymer “ink,” resulting in a 90% reduction in carbon emissions compared to conventional cement. Kelvin6k is positioned as a leader in green construction technology due to its zero-cement process and patent-pending “Made in India” robotics.
Kelvin6k has already established a reputation by building the first onsite 3D-printed structure in India for the Military Engineer Services (MES)
Faster, Leaner, and Greener: Kelvin6K’s Answer to India’s Housing Challenge
While they are not a conventional retail brand, they demonstrate how technology startups can directly cater to consumers and developers by managing all aspects from design to construction.
Due to housing shortages and urban expansion, India requires construction that is both quicker and more cost-effective. Kelvin6K’s approach requires fewer individuals, maintains precision, and accelerates project completion. They also emphasize sustainability, which is gaining more focus in India.
This deal from Shark Tank demonstrates investors’ interest in companies within the realms of deep tech and infrastructure. They are no longer limited to food, drinks, beauty, or skincare brands. Funds are being directed toward technological innovation and sustainable business models. The funding of Kelvin6K indicates that investors are seeking long-term value and impactful growth.
