Rivet
Estimates, underpayment recovery, and denial workflows
- Founded
- 2018
- HQ
- Salt Lake City, UT
- Stage
- Acquired by Zelis (January 2026)
- Raised
- $31.5M
What it does
- Upfront patient cost estimates and good faith estimates
- Payer contract modeling down to the TIN level
- Automated underpayment detection against contracted rates
- Denial and payment variance dashboards
- Worklists for recovery project management
Where it's strong
- Unusually broad integration surface for its size, with 30+ practice management and clearinghouse connections including Epic and athenahealth.
- It pairs front-end estimates with back-end underpayment recovery, so one contract dataset powers both.
- Zelis ownership brings the resources and payer network of a much larger payments company.
What buyers should weigh
- The January 2026 Zelis acquisition means roadmap, pricing, and support models could change; ask hard questions about product continuity.
- Zelis primarily serves 750+ payers, and some provider organizations will be uneasy having their underpayment data inside a payer-aligned vendor.
- Its history is strongest with physician groups and mid-size practices, less proven as an enterprise hospital platform.
Integrations
Sift Healthcare
Payments AI and analytics for the revenue cycle
- Founded
- 2017
- HQ
- Milwaukee, WI
- Stage
- Series B
- Raised
- $40M+
What it does
- Unifies clinical, authorization, coding, and payment data
- Pre-bill denial prevention recommendations (RevProtect)
- Scores denials by overturnability and expected cash
- Guides UR, CDI, and coding staff in workflow
- Payment forecasting and patient payment intelligence
Where it's strong
- Genuine data science depth: models are trained on unified payments data and delivered inside existing pre-bill workflows rather than another standalone portal.
- Its annual Denials Insights report, now in its fourth year, shows real research muscle on payer behavior trends.
- The Series B led by B Capital in 2024 gives it runway to keep investing in its AI products.
What buyers should weigh
- Few publicly named customers; Hartford HealthCare is the notable reference, so demand more references during diligence.
- Value depends on integrating with your claims and clinical data feeds, which is a meaningful implementation lift.
- It is analytics and intelligence, not outsourced staffing, so you need a revenue cycle team ready to act on its recommendations.
