Kelvin6K, a construction company in Chennai, just got ₹1 crore in funding on Shark Tank India Season 5. This is a big deal for India’s tech and startup scene.
Dr. Pradeepkumar Sundarraj started Kelvin6K in 2020. They use concrete 3D printing to make houses faster, cheaper, and with way less pollution.
He went on Shark Tank asking for ₹1 crore for 1.3% of his company. Ritesh Agarwal made a different offer: ₹1 crore for 2.86% equity plus 2.14% advisory equity. The founder agreed, getting money and business advice.

Kelvin6K mixes robotics, sustainability, and construction tech. They use 3D concrete printers made in India to build homes right on-site. This cuts construction time by 50%, costs by 30%, and pollution by 90%. Their business is scalable and has a real impact.
They aren’t a typical retail brand, but they show how tech startups can directly serve consumers and developers by controlling everything from design to construction.
India needs faster, cheaper construction because of housing shortages and growing cities. Kelvin6K’s approach needs fewer people, keeps things precise, and finishes projects faster. They also focus on sustainability, which is getting more attention in India.
This Shark Tank deal shows investors are interested in deep-tech and infrastructure companies. They’re not just looking at food, drinks, beauty or skincare brands anymore. Money is going into tech innovation and sustainable business models. Kelvin6K’s funding shows investors want long-term value and growth that makes a difference.
With this new funding and support, Kelvin6K should be able to improve their business, build more, and get their tech used in more projects. They are trying to lower costs and pollution while building faster, which makes them a player in India’s startup world.
Kelvin6K’s story adds something new to India’s D2C scene. It proves that construction, robotics, and sustainability can be part of the D2C conversation. This funding is a big step towards more responsible construction and shows what’s possible in India’s deep-tech entrepreneurship.
