What Tessol does

Tessol (legally Thermal Energy Service Solutions Private Limited, CIN U29220MH2013PTC240243) is an India-based, privately-held cold chain technology company founded in 2013 by Rajat Gupta (IIT Delhi, Harvard MBA). The company builds sustainable cold chain solutions centered on proprietary Phase Change Material (PCM) thermal energy storage technology, which stores and releases heat via phase transitions and operates independent of vehicle engines or diesel fuel. The product portfolio spans vehicle-mounted systems for secondary distribution (Plug-n-Chill, Blo-Chill, Nova Chill, multi-compartment trucks), portable boxes and bags for tertiary/last-mile distribution (Zenbox Active/Passive, IndiWrap, frozen bags/cartridges), pharmaceutical shippers (Pack N Ship, ROTOMOLDED Range, 72-90 hour holdover at 2-8°C and -20°C), and a real-time temperature monitoring platform (Tamsys). Temprange capability is cited as -25°C to +25°C (with marketing copy claiming -40°C to +40°C for ultra-fast chilling) for durations of 8 to 14 hours across multiple drops, with claimed 60% fuel cost savings and 45% operating cost reduction versus conventional diesel refrigeration.

Tessol generates revenue through three streams: (1) hardware sales and rentals of PCM-based vehicles, boxes, cartridges, and packaging; (2) subscription/recurring revenue from Tamsys real-time monitoring services; and (3) professional services for custom application engineering. Pricing is quote-based, customized to vehicle size, units, temperature range, and contract duration, with multi-year enterprise contracts. Direct enterprise field sales is the primary go-to-market motion, targeting large e-commerce, quick commerce (Swiggy Instamart, Dunzo), retail (Reliance Retail), pharmaceutical (Netmeds), food (Mondelez, Licious, Amul, BigBasket, Theobroma, Polar Bear, Vadilal, Godrej), and produce (Sarda Farms, Sam Berry Exotics) customers. International distribution is via the PLUGnCHILL NZ partner for Australia/New Zealand and a direct Sharjah office for the UAE.

The company operates from a Navi Mumbai HQ with offices in Auckland (regional partner) and Sharjah (UAE sales), and reports having delivered 1 billion units of fresh food across 4 countries while claiming 3 million tons of food wastage prevented and 1 million tons of GHG emissions reduced. Tessol is backed by Mela Ventures (lead, June 2022, Rs 7.5 crore), 1crowdAngels, 1Fund, Infuse Ventures (2014, 2016 lead), Ankur Capital, and Malpani Ventures, and has won the WWF Climate Solver Award (2014), UNIDO Low Carbon Technology Program (2018), Deutsche Energie-Agentur Startup Energy Transition Award (2017), Frost & Sullivan India Award, Emerson Cup, and TiE India Innovation Growth recognition.
