In their own words
OpenComp
OpenComp is compensation decision software for setting pay and managing compensation workflows. It brings together salary, bonus and equity market information for roles across an organization with company pay data synced regularly from HRIS, equity management and payroll systems. Benchmarking can compare pay plans with OpenComp data or a third-party source; its matching process normalizes, levels and matches employee data for comparable benchmarks. The platform includes salary review and approval workflows, budget controls, compensation bands and an audit trail. Headcount models estimate future cash burn and dilution using staffing needs, pay strategy and industry benchmarks. Total Rewards Statements can show employees salary, bonuses, equity and merit increases in a visual report. OpenComp lists Comp Benchmarking, Comp Strategy and Comp Cycles bundles. Comp Cycles is listed at free; paid pricing is on request, with a 14-day trial. The product runs on the web.
