CRHEA and CNRS have signed an accommodation and collaboration agreement with Klearia, which has been set up on CRHEA's premises between March 2018 and May 2021. Klearia is a start-up from the CNRS, which develops glass microfluidic devices. high added value also called "chip labs" and dedicated to users of flow chemistry and analytical chemistry. This start-up was previously housed in the premises of the Center for Nanosciences and Nanotechnologies in Marcoussis in the Paris region. Klearia chose CRHEA for its environment and its technological platform of micro and nano-manufacturing CRHEATEC.

The company Lumilog (based in Vallauris, 06) was created at the end of 2002 by three CRHEA researchers and in partnership with the CNRS to evaluate the results obtained in the laboratory on the growth of GaN. Lumilog manufactured and marketed GaN self-supporting templates and substrates. Lumilog was acquired in 2008 by Saint Gobain. Lumilog ceased operations in 2021.

The SOFTLITE joint laboratory, which brings together the liquid crystal research group of INLN (Institut Non Linéaire de Nice) and Fastlite company, designs and studies optical devices based on liquid crystals to control ultra-short optical pulses. The INLN installed at CRHEA the equipment allowing the manufacturing part linked to liquid crystals, which is the subject of a study within the framework of the SOFTLITE joint laboratory between April 2016 and December 2018.
