Treeline, a San Francisco-based AI powered IT, security, and compliance platform, has raised $25 million in a Series A round led by Andreessen Horowitz to build a modern, centralized IT operating system that automates routine tasks, accelerates onboarding, and delivers proactive support for growing companies.
Treeline, a San Francisco-based provider of AI powered IT, security, and compliance services, closed a $25 million Series A funding round. Andreessen Horowitz led the round, marking the company’s primary institutional capital raise to date and its emergence as a live platform.
How Treeline works?
The round funds Treeline’s development of a “modern IT operating system”, a centralized, software first platform that rearchitects how growing companies handle IT operations. Traditional managed service providers (MSPs) rely on fragmented tools, manual ticketing, and labor heavy processes that deliver reactive support across employee onboarding, device management, identity access, endpoint security, vulnerability patching, compliance audits, and help desk requests. Treeline inverts this model by placing a unified AI and automation layer at the core, standardizing workflows, resolving routine issues proactively, and routing complex decisions to human technicians who remain in the loop for judgment and oversight.
Key performance metrics already achieved include AI agents that augment or fully resolve 98% of customer requests, accelerate employee onboarding 10x (from roughly 20 minutes to 2 minutes), and reduce error rates by 95% on tickets handled entirely within the platform. The system delivers 80% faster overall response times, under one week onboarding for new customers, predictable pricing, and continuous background monitoring that prevents issues rather than reacting to them. Integrations span major enterprise tools including Okta, CrowdStrike, Google Workspace, Microsoft Intune, Vanta, and others, enabling end to end automation of the employee and asset lifecycle while maintaining SOC 2, HIPAA, and similar compliance frameworks.
Founders Peter Doyle (CEO) and Hussain Kader designed the platform after recognizing that incremental tools sold into legacy MSP channels would not suffice. Doyle brings nearly a decade of venture capital experience at Accel, where he backed infrastructure and security companies such as PagerDuty, Heptio, and ServiceChannel. Kader, his Stanford undergraduate friend, complements Doyle with operational and technical depth. The pairing positions Treeline to merge deep domain expertise with modern engineering rather than attempting pure automation that displaces human roles.
Andreessen Horowitz partner Joe Schmidt, who has known Doyle for a decade, led the investment and described it as a full circle opportunity. The thesis centers on the MSP market’s scale, more than $200 billion in annual U.S. revenue across roughly 40,000 firms, combined with global IT spend projected to exceed $6 trillion in 2026. Legacy providers remain small, lifestyle businesses optimized for headcount growth rather than efficiency. Advances in AI now allow a software native operating model that standardizes processes, learns from every resolved ticket, and scales expertise without proportional headcount increases. Treeline partners with select MSPs for specialized human input while embedding intelligence directly into the platform, creating a hybrid that delivers Fortune 100-level capabilities to mid market and growth stage companies.
Capital allocation targets three priorities: scaling the core platform and AI capabilities, accelerating product innovation (including deeper workflow automation and real time leadership dashboards), and expanding the team across engineering, sales, and customer success. The timing aligns with the company’s public launch, enabling rapid go to market execution and early customer acquisition in a market where virtually every business requires reliable IT management yet few can justify building it in-house.

Strategically, Treeline carves a distinct category at the intersection of IT services and enterprise software. It avoids the pitfalls of pure AI substitution by keeping technicians empowered for high stakes decisions, while its centralized architecture eliminates the integration debt and vendor sprawl that plague traditional stacks. This hybrid approach reduces operational waste, lowers risk exposure, and delivers measurable speed and reliability gains that compound as the system learns.
The raise signals strong conviction that AI can disrupt one of technology’s largest and most fragmented service markets. By productizing IT, security, and compliance into a single intelligent operating system, Treeline positions itself to capture share from incumbents still operating on 20 year old models and to serve as the default external IT partner for the next generation of scaling companies. Execution will hinge on seamless delivery of the promised automation while maintaining the human expertise layer that builds customer trust, but the market tailwinds and founder investor alignment create a clear path toward redefining enterprise IT infrastructure at scale.
