StackHPC is a dynamic OpenStack and cloud consultancy that works with leading organisations to provide infrastructure for data-intensive scientific challenges. We’ve been growing for five years with 24 team members, and still retain a startup mindset. An important aspect of our culture is dedication to open source, with the additional values of open design, development and community. All of our development is upstream open source; StackHPC is a committed member of the Open Infrastructure community being a Silver Member founder. Principal staff are active in community efforts around OpenStack and research computing, and our CTO is co-founder and co-chair of the Scientific Special Interest Group. Our customers - which include research institutes and prestigious universities, plus bioinformatics, finance and pharmaceutical companies - use cloud technology and software-defined infrastructure to run scientific applications at scale.
