AI agents are turning SaaS applications into headless, deterministic engines

SaaS applications are being transformed into deterministic engines as AI agents replace traditional user interfaces and drive the rise of the headless enterprise — where AI, not humans, serves as the primary interface for business systems.

As software companies rush to position themselves as headless, the challenge for enterprises is bridging decades of legacy applications with an agentic future while maintaining governance and cost control. That tension is shaping Boomi LP’s product strategy, according to Ed Macosky (pictured), chief product and technology officer at Boomi.

“In your organization, you have a whole series of applications that you rely on to run your business. The traditional enterprise, up until recently, would have to have different teams working in different systems because they each had a head or a user experience you had to move into,” Macosky said. “With the introduction of AI, we actually help bridge to let AI be the head while the applications are headless. The user experience comes through your agentic experiences and makes your applications and your data more ubiquitous in your world. It’s not about no user experience, it’s actually about unlocking the user experience to be multimodal and give different access to the system.”

Macosky spoke with theCUBE’s John Furrier and Gemma Allen at Boomi World 2026, during an exclusive broadcast on theCUBE, SiliconANGLE Media’s livestreaming studio. They discussed the headless enterprise, SaaS applications and Boomi’s platform strategy for governed agentic workflows. (* Disclosure below.)

SaaS applications become headless as the enterprise goes agentic

The headless enterprise concept is forcing SaaS companies to rethink their core value proposition. Rather than competing on user interface design, application providers are repositioning as deterministic rules engines — the referees that govern what AI agents can and cannot do, Macosky explained.

“The SaaS [companies] and the application [companies] are realizing that the true value of the application isn’t necessarily the user experience,” he said. “These SaaS applications are moving themselves into being even more valuable in terms of being the referees for AI trying to do things.”

One of the emergent themes at Boomi World revolves around combining deterministic processes with agentic AI workflows. Purely agentic chains — agents calling agents calling agents — can become prohibitively expensive, according to Macosky. By pairing agentic technology with deterministic workflows for straightforward tasks such as running payroll or submitting expense reports, enterprises can keep costs under control.

“An agent calling a tool that is just a deterministic workflow — ‘run payroll’ or ‘submit expense report’ — that is a very straightforward and very cheap thing to do,” Macosky said. “If that was purely agentic without Boomi underneath it, those would be agents running agents, and the cost has a chance to explode with token consumption.”

Looking ahead, Boomi is betting on hybrid AI infrastructure as the next frontier. The company announced a strategic collaboration with Red Hat Inc. to deliver a single, integrated stack for deploying agentic AI at scale, bringing together Boomi’s Agentstudio with Red Hat AI so organizations can run open-weight models privately, Macosky noted. The priority for the year ahead is unlocking those hybrid workloads in a governed, secure manner — keeping enterprise data in controlled environments rather than routing it through public frontier model providers.

“We are laser focused on [how we’ve] simplified the development of agents,” he said. “Over this next year, helping our enterprise customers unlock the workloads that they want to agentify — that they can’t unlock in a secure way — is what I’m excited about for the next frontier.”
