Matt Barker

Matt was co-founder & CEO of Jetstack, a Kubernetes company he bootstrapped in 2015 before being acquired by Venafi in 2020. Venafi was subsequently acquired by private equity company Thoma Bravo, and then the cybersecurity company CyberArk.

Matt has played a number of product and leadership roles since being acquired, and now leads workload identity at CyberArk (think SPIFFE!) In January 2021, Matt was awarded as a top 100 Open Source Influencer by OpenUK. He also acts as Entrepreneur as Residence for Open UK, and has an advisory role with the AI engineering firm Helix.
