Equity grants at Harness typically include incentive stock options (ISOs) and non-qualified stock options (NSOs).
Jyoti Bansal, who previously founded and sold AppDynamics to Cisco for $3.7 billion, launched Harness in 2017 to replace fragile, script-heavy CI/CD pipelines with an opinionated software delivery platform that automates deployments, rollbacks, feature flags, cloud cost management, and security testing in a single developer console. In December 2025 Harness raised a $240 million Series E led by Goldman Sachs at a $5.5 billion valuation, bringing total funding to roughly $614 million across 14 rounds.
