What Smart Joules does
Smart Joules is an India-based energy efficiency company, founded in 2014 in New Delhi, that delivers HVAC and building energy optimization to commercial and industrial customers under three integrated offerings: DeJoule, an AI- and IoT-powered Building Optimization, Savings and Sustainability (B.O.S.S.) system built on a proprietary Reinforcement Learning algorithm that self-learns from equipment-level telemetry; JoulePays, a Pay-as-you-Save managed service for existing buildings under 7-10 year contracts; and JouleCool, a Cooling-as-a-Service model for new buildings and factories that shifts cooling infrastructure from client CAPEX to total cost of ownership over 12-year terms. The company absorbs the upfront capital expenditure for cooling infrastructure, deploys its own sensors and AI controls, and earns revenue either through shared savings or ongoing service fees tied to measured energy outcomes.
The technology stack centers on continuous, minute-wise automated data logging at the equipment and system level, a unified monitoring platform covering HVAC, fire safety, water, elevators, and CCTV, real-time WhatsApp alerts, and integration with third-party building management systems such as Honeywell. DeJoule can be sold standalone as a subscription-based BMS or bundled with JoulePays and JouleCool deployments, allowing the company to monetize across new construction, retrofits, and pure software engagements. Headcount stands at approximately 200 employees with a founder-led executive team (CEO Arjun P. Gupta, CFO Sidhartha P. Gupta, COO Ujjal Majumdar, plus CPTO and CPO), and operations span India with an initial international commissioning in Indonesia in 2024.
Commercial traction is concentrated in healthcare (Apollo Hospitals across 18 sites, KIMS, Aster, Sunshine, GKNM) and is expanding into hospitality (Le Meridien Gurgaon), manufacturing (ITC, Amneal Pharma), data centers, and district cooling. FY24 operating revenue was INR 49 crore (approximately USD 5.85 million) with 29% year-over-year growth, while net loss widened 94% to INR 91 lakh as the company reinvested. Cumulative reported outcomes include INR 266 crore in client energy cost savings, 32.1 crore kWh conserved, and a 2030 target of 29 million tonnes of CO2 reduction. Funding totals approximately USD 23 million across a $5M Series A (ADB Ventures, 2021), $8M debt (IFU Denmark, 2024), and $10M Series B (SBI Ventures-led, December 2025), with institutional backing from development finance and impact investors alongside strategic capital from Waaree Renewable Technologies.
