Optimist, a startup founded in 2024 by Ashish Goel and Pranav Chopra, has raised $12 million in a seed and pre-Series A funding round led by Accel and Arkam Ventures.
The startup is building air conditioners specifically designed for India's extreme heat, high humidity, and power constraints.
Optimist's goal is to improve cooling efficiency and reduce electricity usage in Indian homes and small commercial spaces.
The company plans to use the funds to scale manufacturing, deepen research and development, and prepare for a market launch.
Optimist's in-house R&D lab in Gurugram has spent months studying thermodynamics, heat transfer, humidity control, and airflow optimization.

India's current air conditioners are not designed for its extreme heat, leading to poor performance during peak summer days.
Only 27–28 million of India's 300 million households own an air conditioner, despite 90% living in heat-affected regions.
Most ACs sold in India are adapted for milder climates, not built for the country's specific conditions.
Optimist's products aim to deliver higher peak cooling capacity than typical five-star rated ACs while being more energy efficient.
