Proxify

Proxify was founded in Stockholm in 2018 (one of its own pages says 2019) and matches companies with vetted developers across web, data, AI and DevOps.

Its network covers more than 5,000 professionals in over 90 countries, and it appeared on the Financial Times 1,000 list in 2025. Matching uses in-house AI tools alongside its hiring team.

Strider

Strider was founded in 2021 by Neal Kemp and Nicole Barra Conde and is registered in Delaware, connecting U.S. companies with remote developers in Latin America. It covers sourcing, vetting, onboarding and retention. The company says every candidate is screened for English, background, culture fit and technical skill through role-specific technical and soft-skill assessments.
