Brown only joined the business earlier in the year as chief operations officer but will now move into her new position with the B2B supplier.
Brown has experience across operations, R&D and commercial management, having worked for software companies across industries such as telecommunications, financial technology and food and beverages.
“It is a tremendous honour to be appointed CEO of Push Technology at such an exciting time; I am committed to ensuring we continue to build on the momentum and success we have achieved in the last 12 months,” Brown said.
“Organisations everywhere are seeking strategies to shorten development timelines, improve operational efficiency, and go-to-market ahead of the competition with their event-driven applications. We need to stay laser focused on the real time data needs of our customers as they look to undertake digital transformation initiatives.”
Push Technology executive chairman John Pocock added: “There’s no better person to lead Push Technology than Grethe as we look to broaden our global footprint. She has an incredible wealth of experience and expertise and her impact at Push has been immediate.
“Her energy and enthusiasm are a real asset to the company. She now has the opportunity to take the company to the next level and drive our aggressive growth plans.”
