SeekOut vs CodeSignal
Side-by-side comparison of AI visibility scores, market position, and capabilities
AI talent search platform that helps recruiting teams source diverse and passive candidates from public profiles, GitHub, and scientific publications.
About
SeekOut is a Bellevue-based talent sourcing platform that aggregates data from hundreds of millions of public profiles across GitHub, LinkedIn, scientific publications, patents, and professional websites to give corporate recruiting teams deep visibility into passive candidate populations. The platform's AI search understands skills and career context rather than relying purely on keyword matching, making it particularly effective for sourcing highly specialized technical, scientific, and executive talent. SeekOut Grow extends the platform to internal talent mobility, giving HR teams visibility into existing employee skills and career interests alongside the external talent market. The platform provides diversity sourcing filters — including gender, ethnicity, and veteran status where legally permissible — to help recruiting teams build more equitable pipelines. SeekOut's integration with ATS platforms including Greenhouse, Lever, and Workday enables seamless handoff of sourced candidates into existing recruiting workflows. Founded in 2017, SeekOut raised $115M in Series C funding at a $1.2B valuation from investors including Tiger Global and Mayfield, achieving unicorn status as a standalone talent sourcing tool.
