President and Cofounder · Cast AI

Career

Gil co-founded Cast AI with Leon Kuperman and Yuri Frayman after their earlier company Zenedge was acquired by Oracle in 2018. His own biography also identifies him as a cofounder of Viewdle, acquired by Google in 2012. Cast AI’s current leadership page names him president and cofounder.[1][6]

Contributions

Explain an adaptive coding platform

Gil presents Kimchi with engineer Žilvinas, who explains the implementation. Their account places model choice, long-running execution and evaluation in the harness, preserving the workflow while changing model providers.[2]

Publish the harness behind the product

Cast AI releases Kimchi’s code alongside its hosted platform. Gil represents the product as the company’s cofounder and president, while the open repository provides the engineering implementation and documentation. This makes the model-selection and workflow approach available for inspection and adaptation beyond a presentation.[1][4][5]

Ideas

In his token-cost article and conference presentation, Gil argues that the price of an individual token can be a misleading measure of agent economics. A lower-priced model can require more attempts or produce work that needs repair. He frames cost around an achieved task and the level of developer use a company can support, rather than treating a token allowance as the outcome.[2][3]
