Crosby Health

Crosby Health envisions a future where healthcare communication is seamless, empathetic, and empowering for both patients and providers. By bridging the critical gap between medical care and administrative processes, we aim to transform how clinical denials and appeals are managed, making healthcare systems more effective and financially sustainable.

At our core lies Apollo, a sophisticated clinical large language model designed to automate and refine healthcare workflows at unprecedented accuracy. Through innovative AI-driven patient engagement tools and secure, scalable technology, we are crafting a new paradigm where healthcare professionals can focus on care while our technology handles complex administrative tasks.

We are committed to building a healthcare ecosystem where every patient feels seen and every provider is equipped with advanced tools that promote efficiency, transparency, and empathy. Our mission is not only to optimize revenue cycle management but to reimagine how healthcare organizations communicate and connect in the digital era.

We stumbled across Crosby Health while researching healthcare AI companies, and honestly, their origin story caught us off guard. Most healthtech startups begin with grand visions of "disrupting healthcare." Crosby? They started because a five-physician practice was drowning in denied insurance claims.

That scrappy beginning shows in everything they've built since. Their flagship product, Apollo, isn't trying to replace doctors—it's tackling the soul-crushing paperwork that keeps them from actually practicing medicine.

What Makes Apollo Different

Here's where things get interesting: Crosby built their own clinical large language model from scratch. While everyone else is retrofitting ChatGPT for healthcare, they trained Apollo specifically for medical appeals and coding tasks. The results speak for themselves—91.8% accuracy on medical licensing exams, which actually outperforms other clinical AI models we've seen.

What impressed us most? Apollo doesn't just write appeal letters. It generates them, submits them directly to insurers (including Medicare), and tracks their progress. We're talking about a 300% speed increase in appeals processing for their partners.

The Revenue Cycle Reality

Let's be real—claims denials are a $19 billion problem in healthcare. Most practices write off denied claims because the appeals process is too time-consuming and expensive. Crosby's automation changes that math entirely.

Their platform handles everything from prior authorization denials to complex inpatient-only disputes. For smaller practices especially, this could be the difference between staying afloat and going under. We've seen too many good doctors leave medicine because of administrative burnout.

Who Should Pay Attention

Crosby's sweet spot seems to be small hospitals and mid-sized clinic groups—organizations big enough to have serious denial volumes but too small for dedicated appeals staff. They're already serving over 4,500 providers across 300+ clinics, which suggests they've found product-market fit.

The $2.2 million they raised in 2024 specifically for Apollo development tells us they're doubling down on their AI advantage. For a company with fewer than 25 employees, that focus could pay off big time.

Bottom line: Crosby Health might not have the flashiest pitch in healthtech, but they're solving a real problem with real technology. Sometimes that's exactly what healthcare needs.
