INTX offers two reinsurance products: INTX Re, a purpose-built operating system for assumed reinsurance, and ReinsureConnect, a cloud-native, AI-ready system that centralises and streamlines ceded reinsurance operations for carriers and fronting insurers.

In an interview with Reinsurance News, Lewis said there is a massive requirement for its reinsurance product, with demand coming from tier one carriers.

He noted, “We have a lot of really big players interested in our reinsurance product, and that’s from tier one to three carriers.

“The main thing is the interest that we’re getting and the quality of people that we talk to. A tier one carrier wouldn’t have given us the time of day with just our core product, whereas on the reinsurance side, we’re seeing a lot of interest.”

Lewis explained that INTX is seeing this traction as insurers seek more effective ways to manage reinsurance, with legacy systems increasingly unable to support growing complexity.

He said, “What’s actually happened with the legacy software market, and I’m talking post mainframe green screen, is that a lot of those systems were developed out of broker platforms or broker systems and broker software systems. What that meant was that there wasn’t really a function on the reinsurance side of things.

“So, you could manage policies and treaties, it was very much a siloed solution. You’ve got one solution for underwriting, a separate one for claims, a separate one for billing, and that all worked very nicely in the context of a broker’s system, but there wasn’t really a reinsurance component to that.

“What’s happened is there are a few very basic quota share systems out there, which, if anything complex, like sliding scale commissions, gets introduced, it becomes very difficult to do anything. It’s not dynamic, and it’s not in real time,” explained Lewis.

He added that there is a significant level of “shrinkage”, reaching as high as 8% in some cases, meaning that with billion-dollar reinsurance programmes purchased by tier one carriers, a material shortfall of up to $80 million takes place.

Lewis continued: “Extra hours are lost, because what everyone’s doing is running Excel spreadsheets between data lakes and trying to manage those processes in a very manual format, rather than it all just being updated dynamically and in real time. And so, that’s created a massive bottleneck in the whole insurance process and in the life cycle of an insurance policy.

“Reinsurance is typically a very big bottleneck, and the numbers involved are significant, especially with the increase that we are seeing in catastrophe risks at the moment, with the flooding, the wildfires, hurricanes, you name it across the world. That’s obviously become very key for a reinsurance carrier to manage.”

INTX shared findings from its latest research, which showed that, from an operational and systems perspective, 72% of insurers still rely on Excel or homegrown systems for critical workflows. In addition, more than 50% of policy workflows require manual intervention, creating latency and operational drag, while organisations lose up to $450,000 annually in productivity due to system inefficiencies and downtime. The research also found that many carriers operate across two to three core systems, with total implementation costs reaching up to $3 million.

From a reinsurance perspective, the commonly cited 1–2% “leakage” reflects only recoverables. Across the full lifecycle—including structuring, placement, accounting and capital—the true impact is closer to 3–8%+ of ceded premium.

These findings highlight the extent to which reinsurance operations remain constrained by fragmented systems and manual processes. Lewis emphasised that within that complexity, INTX removes a significant proportion of the burden.

“What’s given us the impact in this market is really the ability to manage complex reinsurance treaties and facultative contracts. That’s our niche,” he said.

He went on to highlight how ReinsureConnect modernises how carriers handle complex ceded reinsurance.

“We’re designed to integrate into existing carrier and reinsurer environments, not force disruptive rip-and-replace projects,” said Lewis. “A major part of that is helping insurers cleanse and unify fragmented data within a modern, real-time architecture.

“The platform was also built for operational accessibility and flexibility. Insurers can adapt workflows, onboard partners, and respond to change quickly without relying on proprietary expertise or lengthy vendor development cycles.

“That combination of accessibility, configurability, and modern architecture allows organisations to evolve their operations as business and market demands change.”

Lewis explained that a key focus for INTX is allowing flexibility, from the carrier’s perspective, to be able to add new products quickly, as well as add and change structures.

He said, “The key thing is that it’s not just the static system, once you buy it, you can’t do anything to it. To do anything to add a new product, you’re going to run an Excel spreadsheet and a manual process. The system can be adapted very quickly to add new products, to change commission structures, to change loss layers, because on the reinsurance side of things you’ve got one reinsurer that’s carrying you on your first million dollars’ worth of losses, they’re probably taking a net portion between one and two million. And then from two million upwards, you could have anything of 50 cat reinsurers carrying you in that. So, obviously that can be quite complex.”

Lewis explained that as those 50 reinsurers can alter throughout the year, even as often as day-by-day, and with the potential addition of facultative reinsurers if there’s not enough capacity within a treaty, primary carriers need to be very dynamic to be able to change that daily.

“We don’t believe carriers and reinsurers should have to ‘get in line’ every time they need to onboard a new partner or make an operational change,” said Lewis. “INTX was designed to give organisations the flexibility to manage those updates themselves through a simple, highly configurable platform.

“The goal is operational accessibility without sacrificing governance. Business users can make changes quickly without relying on proprietary expertise or extended vendor development cycles, while still maintaining the approval workflows and security controls insurers require.”

Lewis added that INTX’s approach allows insurers to fit modern capabilities into existing operating models while connecting and unifying data across systems to create complete operational visibility.

“There’s an operational uptick here that really resonates. And so, I think that’s where we started seeing this huge influx hit immediately,” he said.
