[back to company universe](https://highsignal.app/case-studies) AI infrastructure # Tennr Tennr is solving the black hole problem in healthcare by leveraging models to digitize the flow of paperwork between healthcare providers. -- Today, when you go to your doctor and need to be referred to a specialist (e.g., for sleep apnea), your doctor sends a fax (yes, in 2024, 90% of provider-provider communication is a 1980s fax). These are often converted into 20+ page PDFs, with handwritten (doctor’s handwriting!) notes, in thousands of different formats.

If you've ever dealt with massive PDFs (i.e. over 1,000 pages), you know how broken search can be. You have no choice but to use “Cmd-F” and manually sift through thousands of search results to find specific information. Professionals in construction, law, finance, and healthcare spend hours doing this every day. Glimmer makes searching these large documents 10x easier. When you upload a PDF, Glimmer uses AI to intelligently index your documeshared extracted concepts: healthcare; shared product terms: pdfs, page, thousand, healthcare; same category: AI infrastructure; shared affiliation: Y Combinator](https://highsignal.app/case-studies/glimmer)[### InferEdge match 59InferEdge builds agentic AI for the buy-side - systems that run autonomously across research, portfolio management, and risk, for equity and fixed income. The point isn't generating a generic note - anyone can do that now. For example, when earnings season hits, our agents produce the quarter's coverage in your analysts' own tone and format, matching how your desk already writes, so it doesn't need a rewrite before it's usable. We build on top of LLMs, turning raw model capability into consistenshared extracted concept terms: model; shared product terms: note, when, format, so; shared affiliation: Y Combinator](https://highsignal.app/case-studies/inferedge)[### Klarismo match 44Fully-automated Quantitative MR Image Analysis. Our software converts a user’s full body magnetic resonance scan (MRI) into a 3D virtual model of their body in the cloud. The model is annotated with explanatory information so they can easily explore and learn about different parts of their body. Klarismo is the only provider of MR analytics that can offer truly scalable analysis for large data collections. Cloud-based processing allows 1000s of acquisitions to be analyzed simultaneously.
