Crosby Health Raises $2.2 Million And Launches Clinical LLM Apollo

By Amit Chowdhry • May 14, 2024

Crosby Health, a health tech company developing proprietary AI to automate administrative tasks, announced the launching of its clinical large language model (LLM) Apollo today. The company also revealed it raised $2.2 million in pre-seed funding led by Amplo Ventures and with participation from NOMO Ventures and angel investors.

Apollo is known as the most advanced LLM for medical reasoning, outpacing many other clinical models with a larger capacity and higher medical knowledge scores. Crosby Health’s newly launched Apollo boasts innovative use cases by analyzing unstructured clinical documentation, like automating clinical appeals from start to finish, from generating the initial appeal to submitting and tracking results.

Hospitals spend tens of billions of dollars every year fighting claim denials, with half of the denials being overturned following strenuous appeals processes. Apollo handles these inefficiencies by automating revenue cycle operations such as medical coding and denial management through AI-driven analysis of clinical documentation.

Apollo streamlines insurance denial management by implementing state-of-the-art AI technology to build robust appeal letters, saving over 98% of the time typically required, freeing up clinician resources to review and edit appeals.

Through a context window of over 200k, Apollo presented the most advanced clinical LLM to date and achieved an impressive 91.8% score on medical license board exam questions, outperforming every clinical LLM available today. This clinical-grade AI jumpstarts healthcare providers to pursue 100% of denials instead of selectively choosing which to appeal to.

Apollo also supports AI medical coding, chart reviews, and other related services, unlocking more revenue for healthcare providers while repurposing clinicians where they are needed most.

Crosby Health also offers Apollo’s capabilities to organizations by onboarding them to its denial management platform or partnering with organizations for specific use cases.  And since licensing Apollo, the community-wellness-focused startup EmpowerMe has been appealing denials 300% faster than traditional human efforts.


“Our AI is revolutionizing administrative tasks in healthcare, so clinical resources can be spent with patients and not on back office tasks. Provider appeals and medical coding is just the start. With our advanced language models, we’re enabling healthcare providers to maximize their revenue by appealing 100% of denials with a higher success rate, automating chart auditing and streamlining medical coding processes.”

– Rishi Gowda, CEO and Co-Founder of Crosby Health

“Partnering with Crosby Health and having access to Apollo has completely revamped our organization and saved us time and team bandwidth. Apollo and Crosby Health are helping to build our clinician’s trust in AI being used in the healthcare space. Using Apollo has enhanced our appeal team’s efficiency and streamlined our revenue cycle management tasks at hyperspeed. We’re able to write appeals at three times the speed, allowing our team to focus on higher leverage tasks.”

– Dr. Jody Mitchell, Chief Medical Officer of EmpowerMe

“We are proud to support Crosby Health’s groundbreaking approach to denial management and revenue cycle automation. The team has built an industry-leading AI model that propels the technology forward and they’ve engineered unique use cases to maximize its impact for people and institutions who need it. Apollo has the potential to revolutionize healthcare operations and improve financial outcomes for providers. This investment aligns with Amplo Ventures’ commitment to backing transformative solutions that drive efficiency and value across industries.”
