After 30 years of academic research in cold atom sciences, intensive developments are being conducted to improve the compactness and the reliability of experimental set-ups. One of the main objectives is to transfer such high-sensitivity experiments from laboratory-based research to an operational utilization outside of the laboratory. This will allow non-specialists and other areas of research to benefit from the outstanding advantages and the measurement capabilities that cold atoms offer. We will present the long-lasting developments that we have been carrying to provide the first industrial cold-atom absolute gravimeter and the first industrial cold-atom atomic clock. We will present the principles of operation and the main features of our instruments. Their performances in terms of sensitivity, stability, and accuracy, as well as the latest results they achieved will be reviewed. High-performance frequency-stabilized laser systems are one of the key technological elements to manipulate cold atoms, and they set the quality of the measurements. Muquans now turned these into benchtop reliable turnkey solutions dedicated to scientists eager to reach faster their scientific objectives. Such laser systems have been qualified on our own cold atom instruments, and a specific focus on our latest developments in this area in terms of performances will be proposed.
