Corendi, based in Sandy, Utah, launched its cloud-native, API-first recordkeeping platform for retirement plan recordkeepers and third-party administrators on 9 November 2026, letting firms run plans under their own brand on a modern core. Fintechbits checked the IRS notice: Treasury and the IRS issued final Roth catch-up regulations on 15 September 2025, and they generally apply to contributions in taxable years beginning after 31 December 2026, which supports Corendi’s timing.

Why Corendi Picked This Moment

The company says it spent four years building the platform, and it points to two deadlines that recordkeepers cannot avoid. Full enforcement of SECURE 2.0’s Roth catch-up rule for high earners begins in 2027, and the federal Saver’s Match, a contribution of up to 1,000 dollars into eligible workers’ accounts, is expected to make its first deposits in 2028. Both mean code changes inside every recordkeeper’s core system.

Dan Beck, Corendi co-founder, said “Recordkeeping technology got much better on the screen, but barely changed underneath it.” That is a fair description of the market. The harder problem is switching: recordkeepers rarely migrate cores, and the release names no client. Corendi will present the platform at the RANDUG annual meeting on 11 to 13 November 2026.

The market structure is the opportunity. The release says the US has more than 40 national and roughly 200 regional recordkeepers, while private equity-backed firms keep buying independent third-party administrators. Smaller firms in that group often run ageing or licensed cores and cannot fund a rebuild. State automatic-IRA mandates add new plans every year; Corendi cites Colorado, where new plans were 18.4% of private-sector plans in 2023, the year its mandate launched, up from 12.6% the year before. A white-label, API-first core aimed at those firms is a sensible niche, provided the start-up can show a live migration from an existing system. Corendi is not the only start-up working on 401(k) plumbing: Fintechbits covered Basic Capital plugging its 401(k) into Check’s payroll rails. And as industry leaders told Fintechbits about embedded finance after launch, the compliance work continues long after go-live.
