Treeline

Treeline is a San Francisco-based AI-powered managed service provider founded in 2024 that gives growing companies a full IT and security team without requiring internal hires. The platform delivers mobile device management, endpoint provisioning, remote monitoring, auth management, dark web monitoring, compliance audit management, and penetration testing through a unified AI and software layer augmented by human technicians for judgment and oversight. Treeline's AI agents autonomously resolve or augment 98% of customer requests and reduce employee onboarding time from 20 minutes to 2 minutes. The company raised a $25 million Series A led by Andreessen Horowitz in March 2026.
