TL;DR

The $100B MSP market is a decade behind because it relies on manual workflows, which Treeline aims to fix by integrating AI and automation with human technicians, not just pure SaaS.

Key Insights

1

The IT and security services market, a $100 billion sector, is at least a decade behind current technological advancements.

2

Traditional Managed Service Providers (MSPs) use an average of 30-35 different SaaS tools, often with poor implementation and legacy processes.

3

Pure-play software, including SaaS, struggles in services categories because businesses have complex, deeply ingrained workflows that require human expertise to navigate.

4

Companies like OpenAI and Anthropic are deploying 'forward-deployed engineers' to help enterprise clients integrate AI, highlighting the ongoing need for human services in tech adoption.

5

Treeline's model involves merging with traditional service providers to gain industry expertise while focusing on organic growth to build a scalable, AI-enhanced offering.

6

AI's biggest impact is currently in individual or small team productivity; integrating it into the trillions of dollars of existing software infrastructure will take time and new business models.

The $100 billion IT services market lags a decade behind

The IT and security services industry, a massive $100 billion market, is significantly behind the curve in technology adoption. Historically, IT tasks required a technician to be physically present with a server. While the past 10-15 years brought improvements through the internet, cloud computing, and better general software, the core operational model has remained largely reactive and manual. This gap is widening with the rapid advancement of AI. Treeline, a modern managed service provider (MSP), aims to reinvent this category by injecting software, automation, and AI to support human technicians, fundamentally transforming service delivery.

SaaS alone fails to solve complex service workflows

Peter Doyle, CEO of Treeline, argues that the prevailing SaaS model, while beneficial for many software categories, falls short in areas like managed IT services. He explains that traditional MSPs are often messy, dealing with unique customer needs and a pool of technicians using 30-35 different SaaS tools to manage everything from onboarding to security and compliance. These tools are frequently half-implemented or outdated. The deep-rooted legacy processes and siloed data within these 15-30 year-old businesses make it difficult to simply layer new software on top. Implementing new tools requires a fundamental re-evaluation of existing workflows, questioning why they exist and overcoming the inherent resistance to change, which is why pure software solutions often fail to capture the necessary workflow ownership.

Integrating AI into legacy systems presents a long-term challenge

The most significant hurdle for AI adoption isn't necessarily the AI models themselves, but the integration into the trillions of dollars of existing software infrastructure that underpins the global economy. This broad pool of critical systems and production environments is complex and will take considerable time and new business models to modernize and interact with effectively. While AI improves individual and small team productivity, its impact on deeper enterprise systems is only beginning to be tapped. The IT and security services sector, valued at over $250 billion, represents a significant area where these integration challenges must be addressed, requiring businesses to truly 'dig into the guts' of their operations.

Treeline's hybrid model blends human expertise with AI

Treeline's model challenges the notion that everything can or should be an AI agent. Recognizing that AI software, however powerful, is difficult to implement and use effectively in critical systems, Treeline embraces a hybrid approach. Unlike typical software companies that might solely offer tools, Treeline’s genesis was as a services company. The goal is to leverage well-built software, automation, and AI agents to progressively shift towards a software-centric model, without abandoning the necessity of human technicians. This approach allows for scalability and a better customer product by embedding AI and automation directly into the technicians' workflow, enabling them to be more efficient and proactive.

The 'forward-deployed engineer' signifies AI's adoption challenge

The rise of the 'forward-deployed engineer' concept, seen with major AI labs like OpenAI and Anthropic, highlights a crucial trend: even the most advanced AI companies find it necessary to employ human experts to help enterprise clients implement and utilize their technology effectively. This is an admission that AI, while powerful, requires significant human effort for successful integration. Treeline internalizes this, viewing human services not as a reluctant necessity but as a core component that enables scalability and a superior customer experience, even as they build out their own software and AI capabilities.

Durable defensibility lies in human-augmented services

In the competitive landscape, Treeline believes the durable defensibility against monolithic AI companies lies in its hybrid model. While pure AI software companies can win, their underlying mechanisms are often automation and workflow development. Treeline asserts that pure-play software will struggle to penetrate services categories that have historically relied on human expertise. By combining human technicians with advanced automation and AI, they offer a unique value proposition. This approach allows them to continuously innovate and compound, moving closer to a software-like model while retaining the essential human element that AI alone cannot replicate in these complex service domains.

Inorganic growth to acquire expertise, organic growth for scalability

Treeline adopted a dual-pronged growth strategy from its inception. This included merging with established traditional service providers, not primarily for revenue, but to embed strong industry insider expertise and experienced technicians into the company's fabric. This inorganic growth provides crucial operational knowledge. Concurrently, Treeline invests heavily in organic growth, aiming to build a scalable offering and speak directly to end customers. This approach contrasts with purely acquisitive strategies, which can sometimes emphasize financial engineering over systemic innovation, to reinvent the category and build a more deeply compounding business.

Future evolution towards trusted partnership beyond IT

Looking ahead 10-15 years, Treeline envisions becoming the most impactful, high-trust third-party partner for businesses. While currently focused on IT, security, and compliance services, the company is laying the groundwork to expand its role. By improving how technicians operate with AI and automation, they aim to enhance customer experience through faster issue resolution and proactive problem-solving. As they quiet the IT and security noise, Treeline can deepen customer relationships, explore new interfaces, offer additional services, and help clients leverage AI themselves. The accumulated data and trust built through their current operations will be foundational for this future evolution, extending beyond traditional IT management.

Common Questions

The IT and security services market is a significant and often underestimated sector, with one estimate placing it at over $250 billion, and another at $100 billion for the managed service provider (MSP) space alone, forming a backbone for the US economy.
