Work that turns product uncertainty into decisions.

A winged menstrual pad in three sizes with no synthetic material in any layer or in its packaging: bamboo viscose, an alginate-chitosan hydrogel in place of petroleum superabsorbent polymer, and a PHA backsheet. I refused synthetics everywhere, accepting an ₹18–25 launch band against ₹4–8 mass market, because every natural brand that kept the price dropped the absorbency with it. At ₹22 the model returns a 43.70% gross margin on a ₹7.45 bill of materials. The next gate is a bench-top core sample, measured for retention under a 1 kg load against Saathi XL.

A location and forward-risk rating system for Indian property: NIRS scores an address on access, environment and hazard, services and trajectory, and publishes the confidence of every output. I killed the legal-rating thesis after finding three funded companies already selling a property rating and driving its price toward ₹99, and repositioned the product onto the one question nobody sells — whether the location is a good place to own. Lenders already spend ₹5,000–25,000 a file on verification, a ₹1,820–9,100 crore pool a rating can share. Gate 1 tests lawful, repeatable access to Karnataka land records in Week 1, before any raise.

A two-part electric toothbrush that moves the primary battery out of the handle and into the charging case. I made the brush functionally dependent on its case, refusing the large handle cell every competitor treats as a selling point, so the section could reach 12 mm — the thickness of a manual toothbrush. The handle carries 40–150 mAh against a category norm of 600–2,000 mAh. Next gate: 3–5 CNC handle mules, to prove a sealed handle closes at or under 12.000 mm around a 16 mm motor and a 14 mm cell.

A 500 ml portable beverage cooler whose Peltier engine chills or heats a drink to 1°C, inside a monolithic aluminium body. I repositioned it from a water bottle once market analysis showed the larger need is chilling any drink. Sold direct at ₹15,000, the model returns a 49.90% gross margin. The next gate is a 30-unit vacuum-seal batch at ₹8–12 lakh.

A passive exoskeleton for adults aged 65–80 with lumbar degeneration, routing 65% of upper-body weight off the spine to the ground through a self-locking knee. I chose partial offload over the full offload powered devices sell, so the wearer's own muscles keep working. At a ₹37,500 retail price the model returns a 46.7% gross margin. The next gate is a 5-unit bench build of the knee brake and composite frame at ₹5–8 lakh.

A 25.0 mm module moulded from mixed, unsorted plastic waste that replaces gravel in a permeable pavement, holding 55% of the layer open by its shape. I killed the strongest geometry for the fastest one, because a part that cannot be moulded at road quantity consumes no waste. At ₹2,052/m² the model returns a 40.01% gross margin. The next gate is a 70-module cure test at ₹1,50,000–3,00,000.
