io Health, a healthtech startup building AI-powered documentation tools for home health and hospice care, has raised $2 million in seed funding led by Nina Capital.

Founded by David Bell, Ph.D., io Health helps clinicians reduce OASIS errors, complete charts faster, and ensure compliance across the complex web of Medicare and home health documentation standards. The funding will fuel product expansion, engineering hires, and deeper EMR integrations as the company scales across the U.S. home health market.

A Deep Pain Point in Home Health

Home health is one of the fastest-growing and most overburdened corners of healthcare. As aging populations drive up demand, clinicians face mounting administrative strain. The OASIS (Outcome and Assessment Information Set) -  a critical dataset used by Medicare to determine reimbursement -  has become both essential and exhausting.

The problem? Even small documentation errors can cost agencies hundreds of dollars per episode or trigger time-consuming audits. Studies show that home health clinicians spend nearly 25–30% of their time on paperwork, often outside of work hours. And according to the Centers for Medicare & Medicaid Services (CMS), a single inaccurate OASIS item can reduce reimbursement by up to $400 per case, bleeding agencies of revenue over time.

io Health’s platform automates accuracy checks, validates chart entries, and flags missing data before submission. Its AI engine integrates directly into EMRs, allowing clinicians to finish documentation in minutes -  without sacrificing compliance.

A Sector Ripe for Transformation

The home health and post-acute care market is on the cusp of massive change. According to Grand View Research, the global home healthcare market is expected to reach $666.9 billion by 2030, growing at a CAGR of 7.96%. Meanwhile, AI adoption in healthcare is skyrocketing -  projected to surpass $187 billion by 2030, growing at a CAGR of 37%, as providers turn to automation to manage data complexity and clinician burnout.

In this context, io Health’s timing couldn’t be sharper. The healthcare system is shifting away from hospital-centric care models toward home-based and value-based care. That transition demands smarter systems for documentation, compliance, and coding -  the very infrastructure io Health provides.

Its platform doesn’t just reduce administrative time; it also makes compliance measurable. And that is where io Health’s real strategic brilliance begins to show.

While many AI health startups are racing to automate clinical notes or summarize visits, io Health quietly went after the hardest and least glamorous problem -  documentation defensibility. It’s not the shiny part of healthcare innovation, but it’s the foundation everything rests on.

In regulated markets, your biggest growth lever isn’t velocity -  it’s trust.

Every healthcare agency wants speed, but none will trade it for uncertainty. What io Health understood early is that the true product isn’t automation -  it’s assurance. When your AI doesn’t just make things faster but makes them safer, you stop competing for adoption -  you become the default.

This is the kind of insight that rewires go-to-market strategy. Founders often chase efficiency metrics, but in domains where compliance, accuracy, or safety are non-negotiable, risk reduction is your strongest form of value creation. io Health designed its engine to make charting “audit-ready” in real time, ensuring every clinician interaction is both faster and defensible.

That’s the hidden superpower: turning something every agency fears -  an audit -  into a product advantage. It’s not just smart; it’s strategically bulletproof.

The Value io Health Delivers

With io Assist™, the company’s flagship product, clinicians can validate OASIS responses, flag inconsistencies, and optimize documentation scores before submission. The system helps agencies:

• Reduce charting time by up to 25%
  
• Improve revenue per episode by 9–10%
  
• Cut QA rework by over 40%
  
• Save 22 minutes per Start-of-Care visit, according to internal pilot data
  

The AI’s ability to integrate seamlessly with existing EMRs -  rather than replace them -  is a crucial differentiator in a fragmented industry where most solutions demand a full-stack migration.

It’s already being tested by home health operators across multiple states, helping teams boost efficiency while reducing the documentation burden that drives turnover.

Market Momentum & Industry Validation

The home health industry is under enormous pressure. CMS has proposed a 9% reimbursement cut for 2026, forcing agencies to do more with less. Meanwhile, the industry is projected to face a shortfall of 446,000 home health nurses by 2030 (Home Care Association of America).

Those forces create a perfect storm for adoption. Tools that save time, prevent denials, and safeguard compliance are no longer optional -  they’re survival infrastructure.

That’s exactly the narrative Nina Capital is backing. The Barcelona-based fund has a strong track record in digital health, investing in AI systems that embed deeply into healthcare workflows rather than merely sitting on top of them. With this investment, io Health joins Nina’s growing portfolio of workflow-automation and patient-safety startups redefining post-acute care.

The Future of AI in Home Care

io Health plans to expand its platform beyond OASIS to encompass comprehensive home health documentation, from visit verification to outcome tracking. The goal: a single AI layer that connects clinical care, compliance, and reimbursement -  transforming administrative overhead into proactive insight.

In the bigger picture, it’s a glimpse of what the next era of healthtech will look like: not AI that replaces clinicians, but AI that defends their time and protects their credibility.

And for founders, that’s the takeaway worth gold -  the kind that doesn’t show up in valuation decks but determines who lasts:

The next generation of AI winners won’t just optimize workflows -  they’ll institutionalize trust in systems that were never designed for it.

io Health isn’t simply chasing speed; it’s codifying safety. And in healthcare, that’s the ultimate competitive edge.
