Treeline raises $25 million Series A funding to rebuild corporate IT with AI agents

Treeline Secures Series A Funding to Challenge Traditional MSPs

Treeline has raised $25 million in Series A funding led by Andreessen Horowitz to transform how businesses handle IT management1

1

. The San Francisco-based startup, co-founded by Peter Doyle in 2024, is building what it calls a modern IT operating system designed to streamline IT services through AI and automation software rather than the people-first approach used by traditional managed service providers2

2

. The round comes as global IT spend is expected to climb above $6 trillion in 2026, with approximately 40,000 MSPs operating in the U.S. alone1

Flipping the Traditional MSP Model with Agentic AI

Most companies can't afford full in-house IT infrastructure teams, so they outsource to managed service providers that sell what Doyle describes as fundamentally "people and tools." Teams of human technicians stitch together dozens of point solutions to monitor environments, provision laptops, and respond to IT support tickets1

1

. Treeline's bet is to flip that model entirely. Instead of starting with people and layering in software, the AI-powered MSP starts with a unified software and AI layer, then brings in technicians for judgment and oversight1

1

. The company's agentic AI now augments or directly resolves 98% of customer requests, while reducing error rates by 95% for tickets solved within its platform3

Dramatic Efficiency Gains Through Automation

The results speak to the potential of augmenting human technicians with AI. Treeline has accelerated employee onboarding from 20 minutes to just 2 minutes—a tenfold improvement3

3

. The company uses its technicians-in-the-loop model to automate IT management tasks like password resets and routine provisioning, freeing specialists to focus on strategic planning, endpoint security, and work in highly regulated environments1

. "What it takes is not being afraid to keep technicians and people in the loop," Doyle told Fortune. "I'm not saying that we should replace technicians. We should empower them"1

Why Venture Capital Is Betting on Services

Joe Schmidt, a partner at Andreessen Horowitz who has known Doyle for more than a decade, sees a major market in small and midsize business IT services ripe for disruption3

3

. "Every MSP, you have so many more customers that you could serve that you're not serving because there's no way to actually call them back," Schmidt told CRN. "The addressable market is literally every small, midsize company in America"2

2

. While venture capital firms typically favor higher-margin SaaS businesses, Schmidt says Treeline's end-to-end ownership model offers quality control that traditional software vendors sacrifice to solution provider partners3

3

. The investment also gives Andreessen a unique window into how AI affects the future of SaaS in a world dominated by Anthropic and OpenAI3

Strong Early Traction Points to Market Demand

Treeline currently serves around 200 customers with about 70 employees and is already profitable3

3

. Doyle expects at least threefold revenue growth this year, driven by what he describes as strong market resonance3

3

. The platform integrates fully automated employee and asset lifecycle management, device and identity management, vulnerability management, insider threat protection, security questionnaire completion, compliance readiness, and audit preparation3

3

. Schmidt is tracking organic growth rates unlocked by capacity increases from the existing team, with no customer outgrowing Treeline's capabilities2

2

. The goal is higher customer satisfaction through net promoter scores while maintaining efficiency2

What Industry Watchers Should Monitor

Doyle comes to this challenge as an investor turned founder, having spent about a decade in venture capital at Accel backing IT infrastructure companies like Pagerduty and Heptio1

1

. He initially thought building a better tool and selling it through existing channels would suffice. "Within the first 10 days, we realized that wouldn't work. We actually needed to fundamentally change how this industry operates," he told Fortune1

1

. The pace of technology and AI is moving so quickly that Doyle believes the MSP industry as a whole isn't prepared to keep up2

2

. For near-term success, Schmidt wants Treeline to build sufficient geographic distribution of qualified teams and expand product surface area so it can service customers across different industries without the skilling-up time traditional MSPs require2

2

. The Andreessen Horowitz-led funding will accelerate product innovation and workforce expansion as Treeline takes on the fragmented landscape of 40,000-plus U.S. MSPs3
