Sunbound wants to fix something most people don't think about until they're signing the checks themselves: how nursing homes and assisted living facilities actually get paid.
The Washington, DC-based startup recently closed a Series A round and says it has now raised $24 million in total capital—a number that might seem modest until you consider what it's built with it. The company reports processing over $1 billion in annual payment volume across 45 states, handling the chaotic mix of private pay, Medicaid, Medicare, and managed care contracts that keeps senior living operators up at night. More than half of payments in this industry still arrive by check, according to Sunbound. That's not a typo.
Founded by Manny Cominsky and Stuart Mason, Sunbound has assembled what it calls a unified revenue operating system for facilities that have historically stitched together admissions software, billing platforms, and claims management tools with all the elegance of duct tape. The company says its payment volume tripled in the twelve months leading up to its Series A announcement this spring—growth that suggests the sector might finally be ready to modernize, or at least willing to try.
Money That Knows Where It's Going
The investor roster mixes familiar venture names—Fika Ventures, Bling Capital, Liquid2 Ventures, Cambrian—with strategic backers whose interest runs deeper than returns.
Omega Healthcare Investors, a publicly traded REIT that owns hundreds of skilled nursing and assisted living properties, took a minority stake in Sunbound last May and formalized a partnership. That's not just capital. That's distribution, the kind founders dream about: direct pipeline into facilities Omega owns or finances. Four months earlier, Live Oak Ventures, the investment arm tied to Live Oak Bancshares, made its own undisclosed strategic investment. The banking angle opens pathways into working capital products and embedded finance, areas where senior care operators perpetually run lean.
Strategic investors with embedded customer bases can accelerate scale, but they also carry expectations. Omega and Live Oak aren't writing checks for philanthropy.
Building Out the C-Suite
This spring, Sunbound announced five senior hires in quick succession: Jiashu Wang as CTO, Jeff Merselis as chief revenue officer, Amy Raymond as COO, Anh Tran leading product, and Jerry Taylor overseeing strategy and business development.
The timing and composition tell a story. Companies don't staff up go-to-market leadership, operations, and product simultaneously unless they've hit something real and need to operationalize it fast. Whether that's sustainable or premature depends entirely on execution over the next 18 months.
The Revenue Cycle No One Talks About
Here's the pitch, stripped down: senior living facilities juggle revenue from families writing checks, state Medicaid programs with Byzantine reimbursement rules, Medicare claims for skilled nursing services, and an expanding universe of managed care contracts. Each stream follows different rules, timelines, and error rates. Most operators manage this across incompatible software platforms or, worse, spreadsheets.
Sunbound claims its system delivers 95% on-time payments and a 99% net collection rate. Those numbers matter in an industry where thin margins and labor shortages make every delayed payment a potential crisis. Last October, the company announced a partnership with Maplewood Senior Living, a multi-site operator that reported reclaiming five business days per month after implementing the platform. That's time staff aren't spending chasing down missing payments or reconciling claims.
Whether those metrics hold as Sunbound scales—and as it moves into the more complex world of skilled nursing facilities, which it says it's targeting this year—remains an open question. Early wins with mid-size operators don't always translate when you're dealing with larger, more entrenched enterprise clients.
What Comes Next (Maybe)
Sunbound now describes itself as offering "Senior Living's AI-First Revenue OS," language that suggests ambitions beyond payment processing toward something more comprehensive: revenue intelligence, predictive analytics, workflow automation. The company says it's layering AI into claims management and revenue cycle operations, though specifics on what that looks like in practice remain vague.
The demographic backdrop is undeniable. By 2030, one in five Americans will be 65 or older, according to S&P Global Intelligence. Senior care is a growth market whether or not the infrastructure improves.
But demographics alone don't guarantee success for a fintech trying to rewire decades-old systems. Sunbound will need to prove it can scale operations without losing the service quality that early customers valued, deepen penetration in facilities that are notoriously slow to adopt new technology, and show that AI automation actually compresses inefficiencies rather than just adding another layer of complexity.
The capital is there. The strategic partnerships are in place. Now comes the harder part: delivering on the promise at scale in an industry where "move fast and break things" has never been the operating philosophy.
