Corelation CEO Rob Landis: KeyStone Is an ‘Outlier’ Among Core Platforms

By John San Filippo

The 15th Annual Corelation Client Conference was held May 14-15, 2026 in San Diego. Corelation CEO Rob Landis sat down with Finopotamus for an exclusive interview to discuss his company’s place in this shifting market.

Corelation CEO Rob Landis

To set the record straight, Landis opened the conversation with a bit of humor regarding the era of generative AI. “Yes, I am actually Rob Landis, CEO of Corelation. This is not an AI deepfake.” But as the conversation turned toward the technical foundations of the credit union industry, humor gave way to a sharp analysis of current market conditions.

Defining the “Legacy” Label

The term “core modernization” has become a buzzword that carries a heavy implication: that what you currently have is obsolete. As Corelation enters its 17th year, it finds itself in a curious position. It’s an established leader, yet it is often categorized with the very “legacy” providers it was founded to disrupt. Landis sees this as both a badge of honor and a categorization error.

“For a while when we were young, we were not taken seriously as a core. So, I should take it as a compliment that now we’re lumped in with the others,” Landis noted. He argued, however, that the “legacy” label should be defined by methodology rather than age. For Landis, a legacy system is characterized by a lack of real-time processing and a reliance on batch-heavy workflows.

“What [legacy] is implying is a methodology that was in place for a long time, but there’s a lot of batch processing, there’s not a lot of real-time, it’s not API-driven,” Landis explained. He maintained that KeyStone remains a modern outlier because it was built from the ground up to be open and real-time. “Real-time integrations being the default instead of being the exception,” he stated, remains a core tenet of Corelation’s architectural philosophy.

The Sidecar Strategy: Workaround or Future Core?

As credit unions struggle to innovate on aging infrastructure, many have turned to a “sidecar” strategy – deploying a modern secondary core to handle specific digital lines of business while keeping the legacy system as the “ledger of record,” Landis said. He also expressed a healthy skepticism for this approach, viewing it as a symptom of a deeper failure in a credit union’s primary technology stack.

“At some point, to get to the place that a sidecar core makes sense, you have to have given up on the fundamental ledger, the system of record for all credit activity, that there’s just no way to get to a modern level for that,” Landis said. He argued that if a credit union accepts that premise, they are essentially managing a “viable workaround” rather than a true solution.

In a surprising reveal, Landis shared that KeyStone has already been utilized as a sidecar, before the term gained its current marketing traction. He described a client that launched a digital-only brand on KeyStone, while keeping their traditional operations on another system. Over time, the credit union merged the traditional brand onto KeyStone. “KeyStone has been used in that way,” Landis confirmed. “We didn’t have that nifty marketing, buzzy term for it, but once it was presented to us, we didn’t see any problems.”

Public Cloud and Deployment Agnosticism

The shift toward the public cloud is no longer a theoretical debate for Corelation. Landis confirmed that the company is currently supporting a live client’s migration into Amazon Web Services (AWS). While Corelation has known KeyStone was cloud-ready for years, this move represents a critical “proof of concept” regarding the regulatory and audit hurdles involved in such a transition.

“We’ve known for a long time that KeyStone works just fine in the public cloud, so it was more riding along from the client experience of what regulatory and exam and audit hurdles they’re facing,” Landis remarked. He noted that while many institutions are interested in the cloud, few wanted to be the “first to jump.” This migration will provide other interested KeyStone clients with a clear path forward.

Landis emphasized that Corelation remains “deployment model agnostic.” Whether a credit union wants a “refrigerator server room in the back,” a managed service environment through partners like Wescom Resources or SwitchThink, or a public cloud instance, KeyStone is designed to perform.

Sunsetting AIX for a Linux Future

Infrastructure evolution at Corelation also involves a major shift in operating systems, he noted. The company is currently in the “home stretch” of migrating its client base from IBM’s AIX (KeyStone’s original operating system) to Linux. Landis views Linux as the platform of the future, offering better opportunities for deployment choice and empowerment.

To handle the transition responsibly, Corelation set a sunset date with its clients’ best interests in mind. “We announced a sunset date for AIX support,” Landis said. “We set it for – it was a full five years out, and it’s I think in 2029.” This will ensure that all clients have the opportunity to fully amortize their AIX-based hardware investments. The migration is intended to unify the platform’s development and support apparatus, ensuring the entire community is running on the most flexible, modern foundation.

Managing Success and the 2028 Horizon

Perhaps the most significant challenge Corelation faces, he conceded, is its own popularity. The demand for KeyStone has reached a point where new contracts are looking at go-live dates in 2028. Landis acknowledged this as a “wonderful problem of high demand,” but one that requires a careful response to maintain quality.

To address the backlog, Corelation is increasing its conversion capacity from 30 projects a year to 36. This growth is being handled with caution; the company refuses to “throw warm bodies” at the problem. “We’re hiring and training all through 2026 so they can do their projects in ’27 for go-live dates in 2028,” Landis explained. “We’re not going to rush it.”

AI and the Humanity Pillar

As Corelation continues to explore AI and generative AI, it is doing so with a specific “pillar of humanity,” Landis said. He rejected the notion of AI as a tool for staff replacement. Instead, he sees it as a way to empower the company’s 500-person team to handle more capacity without losing the personal relationships that define the company.

“We are bringing AI on board to make us better, but not to replace anyone,” Landis stated. By using tools like Copilot and integrating AI into their development apparatus, the goal is to find efficiency gains that allow their current “bench strength” to run further into the future.

Commitment to the Full Community

Despite having signed some of the largest credit unions in the nation, Landis stressed that Corelation remains committed to institutions of all sizes. He described their current client base as a “peanut butter spread” across asset ranges, with about a third of their clients falling into each tier: sub-$250 million, $250 million to $1 billion, and billion-plus.

“This community only works when it’s all working together,” Landis said. He pointed to a progressive client in the $60 million range as evidence that KeyStone isn’t just for the giants. For Corelation, the goal is to provide a platform that allows any credit union, regardless of size, to “take a big exhale” and focus on service rather than the constant patching and interoperability struggles of the legacy past.
