Treeline announced it has raised $25 million in a Series A funding round led by Andreessen Horowitz, as the company looks to modernize IT services through a software- and AI-driven platform.
The funding will be used to scale Treeline’s platform, accelerate product development, and expand its team as it builds what it describes as a “Modern IT Operating System.” The company is targeting a massive and growing market, with global IT spending projected to reach nearly $6 trillion in 2026.
Treeline is positioning itself as a replacement for traditional managed service providers and in-house IT teams, both of which it argues are increasingly inefficient in today’s environment. Legacy IT models often rely on manual coordination, reactive ticketing systems, and fragmented vendor ecosystems, leading to higher costs, slower execution, and operational risk.
The company’s platform consolidates IT, security, and compliance into a unified system powered by automation and AI. Instead of relying on multiple tools and service providers, Treeline centralizes workflows into a single software layer designed to operate continuously in the background, while human experts focus on higher-level strategic decisions.
Treeline’s platform spans three core areas:
- IT functions, including employee onboarding, asset lifecycle management, and technical support automation
- Security functions, such as endpoint protection, vulnerability management, and insider threat mitigation
- Compliance functions, including audit preparation and ongoing compliance readiness management
The company reports strong operational improvements from its system, including resolving or augmenting 98 percent of customer requests through AI, reducing onboarding time from 20 minutes to two minutes, and lowering error rates by 95 percent for fully automated tickets.
Treeline’s approach reflects a broader shift toward embedding AI directly into enterprise infrastructure, rather than layering it onto existing service models. By replacing labor-intensive processes with automation, the company aims to enable businesses to scale IT operations more efficiently without proportional increases in headcount.
The investment from Andreessen Horowitz underscores growing investor interest in rethinking core enterprise functions like IT and security through AI-native architectures. With more than $90 billion under management, the firm has been actively backing companies building foundational infrastructure for the next generation of enterprise technology.
Treeline says its long-term goal is to redefine how IT services are delivered by transitioning from fragmented, service-driven models to centralized, software-first systems that are proactive, scalable, and resilient.
KEY QUOTES:
“Modern technology is reinventing nearly every industry – but this particular category is rapidly falling behind. Managed services still operate much the way they did 20 years ago, built around manual coordination and reactive ticketing. That model creates enormous waste for companies. We started Treeline to rebuild IT from a modern lens – using software and AI to make infrastructure scalable, reliable, and finally modern.”
Peter Doyle, CEO and Co-Founder, Treeline
“Recent advances in AI have created an opportunity to re-architect how IT services are delivered. Treeline aims to define a new category – embedding software intelligence at the foundation of IT, security, and compliance, so companies can scale with greater efficiency and resilience.”
Joe Schmidt, Partner, Andreessen Horowitz
“Treeline doesn’t just keep the lights on – they help us build infrastructure for where our company is going. They move quickly, communicate the way our team does, and genuinely care about the people behind the tickets. With Treeline, we’ve built infrastructure most companies our size don’t have until they’re 3x larger.”
Richard Cho, Head of People, Luma
