About CareerOS

Our Mission

CareerOS exists to give every professional free access to the information and tools that were previously available only to those with expensive career coaches, premium services, or insider connections.

Knowing your market value is not a luxury — it's a necessity. Salary transparency directly reduces pay gaps and helps workers negotiate fair compensation. Our salary data, calculators, and career guides are permanently free because we believe everyone deserves to make informed career decisions.

What We Build

Data Sources & Methodology

Salary data on CareerOS is compiled from multiple public and crowdsourced sources:

• •U.S. Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics
• •LinkedIn Salary Insights (aggregated, anonymized)
• •Glassdoor Compensation Reports
• •Levels.fyi for technology roles
• •Industry-specific compensation surveys and job posting analysis

All salary figures represent base compensation only and exclude equity, bonuses, and benefits. Ranges reflect the 25th–75th percentile for full-time employees. Data is reviewed quarterly and weighted toward the most recent 12 months of postings.

Editorial Standards

Every page on CareerOS is reviewed before publication. Our editorial process includes: data cross-referencing across at least two independent sources, expert review for methodology accuracy, clear disclosure of data limitations, and quarterly updates to maintain accuracy.
