Praan Tech Stack

Filter-less air capture and CO₂ removal technology with IoT monitoring

Environmental Services San Francisco, California 11–50 employees Founded 2017 Privately Held

Praan operates a hardware-software stack for particulate and CO₂ capture from ambient air, combining embedded systems (ARM, RTOS, MQTT) with cloud data pipelines (Node.js, React, PostgreSQL, AWS/Azure). Active hiring across engineering, design, and sales—with notable velocity in design and manufacturing roles—reflects a company scaling from prototype toward commercial production. Projects include new embedded platforms, sensor calibration systems, and commercial certifications (UL, LEED), while pain points cluster around manufacturing cost reduction and channel partner execution.
