In 2017, Levels.fyi aimed to tackle the lack of transparency in salary data, making it easier for professionals to compare compensation across various roles and companies. Since then, the platform has grown significantly, with millions now using it to gain insight into pay structures. The focus remains on reducing information asymmetry, which benefits both employees and employers by providing a clearer picture of compensation norms. The report for 2025 reflects data collected from individuals who voluntarily shared their salary information. This crowdsourced data enhances the reliability and depth of the insights provided, allowing users to make more informed career decisions. Levels.fyi encourages users who have gained from this transparency to contribute their own compensation details, further enriching the dataset for future users. The report serves as a resource for professionals looking to understand their market value better. By analyzing salary trends, roles, and companies, it aims to empower users to negotiate better pay and advance their careers.
