INTX Insurance Software, the Austin, Texas maker of software for reinsurers, said on 10 November 2026 that GreenieRE, an impact-focused reinsurer supporting new energy technologies, has selected INTX Re, its platform for assumed reinsurance, to receive, standardise and validate premium, exposure and loss reports from its insurance and programme partners. INTX says GreenieRE went live on INTX Re in less than 60 days. Fintechbits found no earlier coverage of INTX or GreenieRE in its archive. The Clean Growth Coalition committed $200 million to GreenieRE in February 2025 to expand clean energy insurance, Reinsurance News reported.

What INTX Re does for GreenieRE

According to the INTX release, bordereaux are the periodic reports cedants and programmes send to a reinsurer listing risks written, premiums and losses. As the number of partners grows, differences in formats and detail make validation and financial reporting harder long before the data reaches the reinsurer’s wider operation.

GreenieRE will use the platform’s bordereaux component to receive, standardise, validate and manage those reports through one process, aiming to reduce manual handling and improve the reliability of incoming data as it adds programmes and counterparties.

Amy Antczak, GreenieRE’s chief operating officer, said: “As we expand our network of insurers and program partners, we need a reliable way to bring that information together and put it to work.”

INTX says bordereaux management is one part of the product, which is designed to support the wider assumed reinsurance lifecycle, including treaty and facultative business.

The under-60-day go-live is the release’s main proof point. Insurance core projects often take a year or more, so a fast start on one module is a sensible way for a small reinsurer to test a vendor. It also limits the cost of failure: if the module disappoints, GreenieRE has not rebuilt its whole operation around it. If it works, the next modules follow on proven ground.

Energy risks and the data problem

GreenieRE covers emerging energy technologies such as solar, storage and other transition assets, where loss histories are short and data formats vary. Pricing and monitoring those risks depends on accurate exposure data from partners, because there is little historical experience to fall back on.

That makes bordereaux quality more than an administrative issue. If a reinsurer cannot see accurately what its partners have written, it can drift outside its intended risk appetite, a problem Fintechbits highlighted in coverage of Federato’s underwriting survey.

Why INTX Re Targets an Unglamorous but Costly Gap

The INTX Re platform is aimed at one of the least glamorous and most persistent problems in reinsurance: spreadsheets of uneven quality arriving from many partners. Reinsurers employ teams to clean and reconcile them, and errors feed into reserves and financial statements. Software that standardises the intake saves time and reduces mistakes.

For a specialist reinsurer like GreenieRE, the stakes are higher than usual. Programme business, where managing general agents write risks on a reinsurer’s capacity, depends on trust in partner data. A reinsurer that can monitor programmes closely can grow them faster without losing control.

The market for reinsurance software is small and dominated by a few established vendors, so a young firm needs early clients and quick wins. The release gives no pricing or client count for INTX. Fintechbits has covered pricing pressure in other specialist lines, such as trades insurance.

Speed of implementation is a real selling point in this niche. Reinsurers live with legacy systems because replacing them is slow and risky. A vendor that can show value from one module in two months gives buyers a low-risk way to start, and a path to sell the rest of the platform later.
