Enterprise AI: Build or Buy?

Agent sprawl is emerging as a hidden but rapidly growing risk in enterprise AI adoption, creating governance gaps, duplicated infrastructure, and operational inefficiencies. Without a unified platform approach, organizations risk turning early AI success into long-term technical and compliance debt.
Something quietly happened in most enterprises over the last eighteen months. It did not show up in a budget line. It did not trigger a risk alert. And no single team owns it. Department by department, teams began deploying AI agents.
Finance built one to handle invoice validation. HR deployed one for onboarding queries. Customer support spun up another for ticket triage. Each solved a real problem. Each was approved, or at least not stopped. And each was built on a different platform, with a different model, against a different data connection, governed by nobody in particular. That is AI agent tool sprawl. And by the time most tech leaders name it, money has already been lost.
Agent sprawl is not a new type of problem. It is a familiar one wearing new clothes. The enterprise has already lived through cloud sprawl - dozens of uncoordinated cloud environments consuming budget and creating security gaps that took years to unwind. It lived through SaaS sprawl; the average large enterprise operates thousands of applications. CIO Dive shares that over 61% of discovered applications aren’t formally approved or overseen by IT teams.
And it lived through RPA sprawl - a wave of automation bots that began with promising pilot results and ended as a tangle of fragile, overlapping workflows that nobody could fully audit or maintain. Autonomous agents are like RPA with a brain. The same dynamics apply, but the consequences move faster and reach further. An RPA bot that breaks stops working. An AI agent that operates without governance keeps working - and that is the more dangerous scenario.
The pattern is consistent across organizations, even if the details differ. It typically begins with a small number of well-intentioned pilots. The results are good enough to encourage expansion. Other teams notice, request their own agents, or simply build them. Vendors make this easy - enterprises are lured in with free or cheap tools, and there is little to discourage adding yet another platform to the mix. Within twelve to eighteen months, a typical enterprise finds itself in a position where: Agents across different functions are built on different platforms (OpenAI, AWS, Google, internal tooling) with no unified way to observe or manage them. Because each one is being built in a different way, there is no single pane of glass from a management perspective.
Each agent has its own data connections and access permissions, configured independently, with no shared policy layer. Nobody has a complete picture of which systems each agent can touch. The same integrations are being rebuilt repeatedly. Five agents, five separate connectors to Salesforce. Three agents, three independent pipelines to the data warehouse. Agents operating in adjacent functions have no shared context and no coordination layer. When your marketing agent, supply chain agent, and HR bot all operate in silos, you don't have an automated workforce - you have a digital riot. And model choices have become ad hoc. Different teams are using different providers based on what was available when they built, not based on any strategic standard for cost, performance, or risk.
The most visible cost of agent sprawl is the budget waste - redundant integrations, overlapping capabilities, duplicated infrastructure. That is real, and it compounds quickly. But the less visible cost is the governance debt. Every agent that operates without a central policy layer is a gap in your compliance posture. Every agent that runs without observability is a liability you cannot quantify. And in regulated industries like finance, healthcare, or legal, that gap is not theoretical. It’s an audit finding waiting to happen. Uncoordinated agents lead to token hemorrhaging, where redundant API calls and overlapping compute tasks quietly erode ROI.
More seriously, they can lead to real operational failures when agents with conflicting goals operate on the same data without any orchestration layer reconciling their decisions. When leaders move too quickly to put tools in employees' hands, important governance and rollout decisions get overlooked - and that lays the groundwork for sprawl. The cost of retrofitting governance onto a sprawling agent fleet is, in every case, significantly higher than the cost of having the governance infrastructure in place from the start.
By early 2026, the novelty phase of AI agents has officially ended and been replaced by a looming systemic liability. If 2025 was the year of the pilots, 2026 is the year of the collision. Gartner's 2026 CIO Survey reveals that 42% of enterprises plan to deploy AI agents within the year. Many of those deployments will not be led by IT. Business units are building their own agents, on their own timelines, with their own tool choices.
The window in which a CIO can get ahead of this is narrowing. The organizations that contain sprawl before it compounds do so by making one strategic decision early: they treat enterprise AI agent infrastructure as a platform problem, not a deployment problem. They establish a centralized control plane as a single place where agents are governed, customized, observed, and deployed. Before the agent count grows beyond the point where governance can be retrofitted. CIOs should focus on creating an enterprise-wide process for lifecycle management, observability, security, and ROI measurement before agents proliferate. Leaders should take cues from DevOps and MLOps: tooling, guardrails, measurement, and central policy layers are key.
Map every active agent across the business, including the platform it was built on, the data it can access, the systems it touches, and who is accountable for its behavior. Most organizations discover more agents than expected, often with broader access than intended.
Focus on ensuring every agent operates on shared infrastructure, including common governance policies, shared knowledge context, and consistent observability. This allows business units to tailor agents to their needs while enabling IT to maintain control.
Treat model selection as a strategic, platform-level decision. Define which providers are approved, establish cost and performance standards, and set clear guidelines for exceptions. This helps make sure that teams are not making these decisions independently.
Every major technology wave in the enterprise has followed the same arc. Rapid adoption, fragmented tooling, governance debt, costly rationalization. Cloud, SaaS, RPA…each required a significant and expensive clean-up phase that would have been far cheaper to avoid. AI agents are on the same curve. The difference this time is that the CIO community has the benefit of pattern recognition. The organizations that act on it now, by establishing the control infrastructure before the sprawl compounds, will be the ones that turn AI agents into a sustainable competitive advantage rather than a growing technical liability.
