About the company
Infracost is a FinOps platform that shifts cloud cost management left—embedding cost awareness, governance, and optimization directly into engineering workflows like GitHub, GitLab, and Azure DevOps. By showing the cost impact of infrastructure code changes before deployment, Infracost transforms FinOps from a reactive, post-spend function into a proactive discipline that prevents expensive mistakes before they occur. Engineers gain pre-deployment visibility into cloud costs, receive real-time alerts that enforce budget guardrails, and benefit from automated policy enforcement that scales FinOps standards organization-wide. With features like AutoFix—which generates pull requests to resolve cost, tagging, and policy issues automatically—teams can address problems in seconds during code review rather than hours after deployment. For FinOps teams and managers, Infracost provides detailed reports highlighting non-compliant resources, outdated instance types, and tagging violations, pinpointing the exact lines of code to fix. Backed by Y Combinator, Sequoia, and SV Angel, Infracost empowers organizations to make cloud cost optimization part of the development process itself—delivering immediate feedback, consistent governance, and sustainable cost efficiency at scale.
