Rivio bets on guaranteed hospital revenue, not another software; US$21M at 6 months old
Two Stanford-trained founders guarantee hospitals collect 100% of what health plans owe; US$21M raised and R$500M valuation within a year of founding.
Rivio
What the business is
AI-run revenue-cycle management for hospitals: audits medical bills, contests denials, and collects from health plans — with a guarantee that Rivio covers any shortfall.
Starting capital：US$21M total: Series A (Monashees, Valor Capital, Endeavor) plus a Positive Ventures extension, Dec 2025–Feb 2026
How it started
Founded in mid-2025 after the pair saw hospitals leaving R$5.8 billion in billings uncollected in 2024 (per Anahp). Instead of another software license, they designed an end-to-end service that audits accounts, integrates health-plan rules, automates billing, and carries the financial risk itself.
What happened
Six months after founding, in December 2025, Rivio raised R$100M (about US$20M) from Monashees and Valor Capital Group with Endeavor at a R$500M valuation. In February 2026 it added a US$1M extension from impact fund Positive Ventures. The platform was already in implementation at more than 50 hospital units, with partners reporting roughly 5% revenue gains in the first month.
How it ended up
Still scaling: technology live in 50+ hospital units as of early 2026, backed by what Valor Econômico called one of the largest rounds ever in a Latin American healthcare company under a year old; the stated goal is to become the operating system for healthcare administration in LatAm.
Background
Rivio's bet is that Brazilian hospitals are not short of software — they are short of money. The pair behind it, Ricardo Sales and Silvio Frison, founded the company in mid-2025 after seeing hospitals leave R$5.8 billion in billings uncollected in a single year because of denied claims, billing errors and operator-rule complexity. Rather than sell a tool to manage that chaos, they promised to fix it: if a hospital does not receive 100% of what it is owed by health plans, Rivio covers the difference.
The product is a revenue-cycle operation run by AI agents: they audit medical accounts, spot inconsistencies, apply each operator's rules, recommend corrections and automate large parts of billing and appeals. The hospital offloads the whole administrative risk; Rivio's engineers and technicians run the collection process end to end. That model turned a software purchase into a performance contract.
Capital came almost immediately: in December 2025, six months in, Monashees and Valor Capital Group led a R$100M (~US$20M) round with Endeavor, valuing the company at R$500M — Valor Econômico noted it as one of the largest raises ever for a LatAm health company under a year old. A US$1M extension from Positive Ventures followed in February 2026, by which point the platform was in implementation in more than 50 hospital units.
What has to be true
- Both founders had proven they could build and exit large businesses: Sales sold Isaac to Arco for US$150M; Frison built Serasa Consumidor, the world's largest credit marketplace with 90M+ users.
- The performance guarantee removes the buyer's main objection — software that doesn't pay for itself — because the vendor now shares the financial outcome.
- The pain is concentrated and quantified: R$5.8 billion withheld from Brazilian hospitals in 2024 alone (Anahp), which makes the value proposition measurable before the first sale.
- Backing from Monashees, Valor Capital, Endeavor and Positive Ventures signals that the risk-taking model, not just the AI, is what investors were underwriting.
What can be applied
Sell the outcome, not the tool: by guaranteeing reimbursement and taking the downside, Rivio changed the pitch from 'another system to buy' to 'who carries the risk'.
Aftermath
As of early February 2026, Rivio had announced US$21M in total funding (Monashees and Valor Capital Group leading the Series A with Endeavor, plus a US$1M Positive Ventures extension) and said its platform was in implementation at more than 50 hospital units across Brazil, including some of the largest healthcare brands in Latin America, with partner hospitals reporting around 5% revenue growth in the first month. The company's stated goal is to become the main operating system for healthcare administration in Latin America, starting with the revenue cycle.
