Machine Learning for Sensor Data

Qeexo develops machine learning solutions that generate actionable insights from sensor data.
The company works with leading device OEMs and component manufacturers to power new and exciting user experiences on hundreds of millions of devices worldwide. In industries such as mobile, IoT, and automotive, there are billions of devices where computation and memory are highly constrained. Qeexo’s proprietary, low-latency, low-power models are engineered to have an incredibly small footprint – ideal for making high-accuracy predictions in these environments.

Spun out of Carnegie Mellon University, Qeexo is venture-backed and has offices in Silicon Valley, Pittsburgh, Shanghai, and Beijing.
