Are Your Teams Quietly Replacing SaaS?

...
Inside many enterprises, the build-versus-buy debate isn’t really a debate anymore. It’s happening quietly, workflow by workflow.
A recent survey of 817 Retool customers and builders found that 35 percent have already replaced functionality of at least one SaaS tool with something they built themselves. Seventy-eight percent expect to build more in 2026. And 60 percent reported creating tools outside of IT oversight in the past year.
At first glance, this looks like a cost story. “The cost of building custom software has collapsed,” said Retool CEO David Hsu. What used to take weeks of engineering time and six-figure budgets can now, in some cases, be prototyped in days. When the math changes that dramatically, behavior changes with it. The default question shifts from “What should we buy?” to “Can we build this?”
But companies aren’t ripping out core systems. They’re targeting the parts that never quite fit—approval flows, dashboards, admin panels. The narrow, frustrating workflows that live between bigger platforms. One replacement doesn’t seem disruptive. A dozen changes how work actually gets done.
That’s where the real tension shows up. Much of that building is happening outside IT oversight. Hsu called “shadow IT at this scale” a demand signal. Teams are building because they can—and because there are real needs. The issue isn’t whether they should experiment. It’s what happens when those experiments turn into production systems without proper oversight.
That gap between capability and readiness echoes what Suraj Srinivasan, professor at Harvard Business School and host of Newsweek’s The AI Agenda webinar series, has described in enterprise AI more broadly. Organizations are understandably cautious about privacy, customer harm and safety risks. But, as he noted, an overabundance of caution means that “you cannot get the most value from the technology.” The same pattern is emerging here. Building is getting easier. Oversight and measurement are still catching up.
The risk isn’t one internal tool. It’s accumulation. Dozens of unsanctioned applications connected to production data create complexity, unclear ownership and expanding security exposure. Trying to block internal building may push it out of view. Letting it grow without guardrails invites fragmentation.
“The most important decision isn't whether to build—your people are already building,” Hsu said. “The decision is whether that building happens in a governed environment or in the shadows.”
Enterprises that treat governance as a core capability—not an afterthought—are more likely to turn this shift into an advantage. Those that don’t may find that the bigger risk wasn’t replacing SaaS. It was losing visibility into what replaced it.

What’s one recent insight you’ve learned about AI?

...
“What's become clear to me is how profoundly AI is changing where decisions get made, moving from distant data centers to the devices and systems right in front of us. In physical security, for example, advancements in edge processing now enable organizations of all sizes to use AI-powered analytics capabilities, generating actionable insights before the data even leaves the device. That means it isn’t just large, well-resourced organizations enjoying the benefits of AI. As the technology becomes increasingly democratized, it’s delivering real, impactful results across nearly every industry.
At the same time, I’ve been reminded how essential human context, governance, and responsibility remain. AI’s impact depends on how carefully and intentionally it is designed and deployed. Transparency, explainability, and respect for privacy must be built from the start if we want people to trust the technology and see lasting value from it. That realization continues to shape the way we build and deploy AI, using the technology as a tool that augments human decision-making to strengthen safety and efficiency while addressing ethical concerns from the earliest possible stage.”

For many mid-market businesses, the challenge isn’t collecting data—it’s using it. Valuable operational information sits inside enterprise resource planning (ERP) systems, but without the technical expertise or resources to deploy and manage AI, much of that data remains underleveraged. At Acumatica, the question was how to turn that latent data into everyday decision support without adding complexity.
To close that gap, the company built a way to embed AI directly inside the workflows business users already rely on. Through Acumatica AI Studio, a no-code environment, users can configure AI-driven actions using natural language prompts—without developers or data scientists. Support teams can automatically generate structured closure notes as cases are resolved, finance teams can flag anomalies or summarize transactions and operations teams can update records or generate insights as part of routine processes. Because AI Studio integrates with large language models from providers such as OpenAI and Anthropic, businesses can align deployments with their governance and model preferences.
The focus was not on experimentation, but on simplifying everyday work. Tasks that once took minutes or required multiple handoffs can now be completed by one person in seconds. “Mid-market businesses don’t need experimental AI projects,” said Miten Mehta, chief engineering officer at Acumatica. “They need tools that solve real problems immediately, without disrupting existing processes.”
According to the company, customers have eliminated time-consuming manual work, enabling faster case resolution, fewer manual updates and errors in finance workflows and quicker access to actionable insights. Acumatica says the result is higher productivity, better data quality and faster decision-making.
In the mid-market, resources are finite and experimentation is expensive. Embedding no-code AI inside core systems shifts the equation. Instead of layering on a separate initiative, intelligence becomes a built-in capability, one that allows smaller organizations to operate with a level of efficiency traditionally reserved for much larger enterprises.

Magic Moment
What’s the most fun or unexpected way you’ve used AI lately?

...
“I’ve actually written a ton of stuff over the last year using AI… I’ve written a bunch of software tools that enable us to model out scenarios with our customers. That was something I basically wrote on nights and weekends, because I could. In the pre-AI era, that would have been a few months of a software project—here it was a few weekends.”
