cool Ant

Monish Siripurapu is Season 3's most architecturally visionary climate-tech founder. An architect and installation artist who graduated from the School of Planning and Architecture (SPA), New Delhi (one of India's most prestigious architecture schools), he founded Ant Studio as an architecture practice and CoolAnt as the product innovation arm that emerged from his architectural research into nature-inspired building cooling. The founding insight came from observing two of nature's most efficient builders: ants and bees. Ant hills maintain remarkably stable internal temperatures despite extreme external heat because their structures facilitate continuous airflow and ground-cooling. Beehives use honeycomb geometry to optimise structural strength and ventilation simultaneously. Monish combined these biological principles with computational design to create terracotta-based building facades that cool indoor spaces using evaporation and natural airflow, without electricity, without chemica

CoolAnt is the world's most aesthetically beautiful passive building cooling technology, converting building facades into functional cooling systems using terracotta (traditional Indian clay material) shaped through computational design into parametric patterns that facilitate evaporative cooling, sun shading, and natural ventilation simultaneously. The technology works through three integrated mechanisms: shading (the terracotta facade elements block direct sunlight from hitting the building's walls and windows, with spacing adjustable according to the orientation and angle of the sun), ventilation (the parametric shapes create natural air channels that draw cool air upward through the facade), and evaporative cooling (water is added to the terracotta elements, which absorb and slowly release moisture, cooling the air passing through them by up to 15 degrees, the same principle that traditional Indian matka water pots use).

Amount Asked: ₹90 lakhs Equity Offered: 1% Implied Pre-Money Valuation: ₹90 crore

Monish walked into Season 3 Episode 44 as the episode's most environmentally urgent founder. He opened with the global climate statistic that frames CoolAnt's entire mission: air conditioners and refrigerators account for 16% of greenhouse emissions globally, and India's cooling demand is projected to grow 8x by 2038, making passive cooling solutions not a luxury but a climate necessity. The product demonstration showed photographs and videos of CoolAnt installations across 30 buildings: terracotta facades creating stunning geometric patterns on building exteriors while simultaneously cooling interiors by 30 to 70% without electricity. The visual beauty of the installations was the pitch's most immediately compelling element: CoolAnt does not just cool buildings, it makes them architecturally magnificent.

Vineeta Singh was the first to exit, stating the business was not investable for her at this stage. Namita Thapar exited citing the valuation was unreasonable considering the revenue. Anupam Mittal exited citing unpredictable future revenue streams. Aman Gupta exited stating he was simply not excited about the building cooling category. Ritesh Agarwal was the last to exit, stating he was not yet convinced the product would be commercially successful.

No Shark made a formal offer. All five exited before entering negotiation. The unanimous concerns about ₹90 crore valuation on minimal documented revenue, ongoing lab testing (results not yet validated), custom-designed installations (limiting standardisation and scaling), unpredictable revenue streams, and the niche building facade cooling category prevented any Shark from constructing an investment thesis.

Monish Siripurapu left Shark Tank India Season 3 Episode 44 without any investment. All five Sharks declined, each citing specific commercial concerns while acknowledging the environmental significance of passive building cooling. The technology was genuinely revolutionary (biomimicry-based cooling without electricity or chemicals), the installations were visually stunning, and the climate urgency was undeniable, but the commercial readiness gap between an architectural innovation and a venture-scalable product prevented every deal.

Our research into CoolAnt revealed that while they did not get a deal on Shark Tank India, their appearance on the show had a positive impact on their business. This has given them validation and exposure all over India which would, in turn, translate into sales. CoolAnt and parent company Ant Studio continue operating from New Delhi. Post-Shark Tank installations include a commercial complex facade in Bilaspur, Chhattisgarh (completed January 2024) using AeroLeaf parametric shading, and community education projects supported by Social Alpha grants providing climate-responsive learning spaces for underprivileged children. The LinkedIn profile showcases continued innovation: the "Cooling Cacti" installation (terracotta cactus-shaped cooling structures for outdoor spaces), residential AeroLeaf facades, and collaborations with NGOs working with underprivileged communities.
