Functionize, Inc.
Functionize is a transformative AI-native platform revolutionizing Enterprise Agentic Automation by integrating AI, ML, Big Data and Advanced Computer Vision into a cohesive solution that automates software test creation, maintenance, and scaling to streamline testing processes and extend to broader enterprise workflow automation.
Founding Story
The idea came from work at Tamas Cser's consulting firm DigiSmart where he noticed project teams lacked time for proper testing while companies were releasing daily changes. He concluded that hiring a dedicated team for testing was infeasible, and paying existing developers to write test code was unsustainable. Cser wrote the first line of code in Fall 2013 as a side project and worked on it for two years. His vision was to enable non-technical team members to define tests with the same level of power and sophistication as a developer, leveraging data science and cloud computing to generate tests without manual writing. The company was officially founded in 2014 and launched its cloud-based autonomous testing platform in 2015 to address what Cser termed a 'QA winter' and help engineers shrink maintenance needs, reduce risk, and accelerate time to market.
