Risk Never Sleeps Podcast: Episode #165
How AI is Making Hospital Workflows Smarter and Faster
Guest: Nicholas Lin, Co-founder & CEO, Guava
Host: Ed Gaudet (with special co-host Mark Gaudet)
Date: December 16, 2025
Episode Overview
In this engaging episode, Ed Gaudet sits down with Nicholas (Nick) Lin, the Co-founder and CEO of Guava, to explore how AI is revolutionizing hospital workflows—specifically the burdensome process of medical prior authorization. Lin discusses how Guava leverages AI agents to automate time-consuming administrative tasks without accessing Protected Health Information (PHI) or Electronic Health Records (EHR), thus addressing both efficiency and compliance concerns. The conversation delves into startup challenges, risk aversion in healthcare innovation, and the importance of balancing progress with patient safety.
Key Discussion Points and Insights
1. Guava's Mission and Origin Story
-
Founding Background
- Nick and his co-founder Kelvin met at NYU, bonding over a lack of a weightlifting club and demonstrating early initiative by founding one themselves.
"We were like, why does the school not have a weightlifting club?...So a few days after we met, we're like, why don't we just make the club ourselves?"
— Nicholas Lin [01:57]
-
Startup Genesis
- Both founders have families in medicine and wanted to make a tangible impact. After extensive conversations with specialists and administrators, they zeroed in on the inefficiencies of prior authorization.
"We got a really good sense that obviously we could focus on the manual workflows and that obviously can be automated."
— Nicholas Lin [08:18]

Memorable Moments & Notable Quotes
-
On AI Empowerment, Not Replacement
"Hospitals already have teams working on these issues. It's just that they're taking too long with outdated manual workflows...these teams can actually use Guava to get rid of maybe 90%, 90, 95% of the time consuming steps."
— Nicholas Lin [05:00]
-
On Hospital Innovation Reluctance
"No one wants to be the one that takes the risk...they're like, if it's working as it is, which it's not...They don't want to take the risks to be the one that takes the first step forward."
— Nicholas Lin [10:50]
-
On Integration and Company Philosophy
"[Guava is] a connection between, I think, healthcare and tech, where that doesn’t exist right now...I want to make it a tech integration."

Summary Takeaway
This episode presents a compelling case for how thoughtfully engineered AI can address urgent healthcare workflow issues—if innovators commit to both empathy for hospital concerns and operational creativity. Guava’s journey so far illustrates both the pain points of health IT adoption and the possibilities when founders listen closely to users and compliance gatekeepers. Lin’s closing challenge—questioning whether the status quo is truly sustainable—offers a call to action for healthcare leaders everywhere.
"At a certain point you have to take a risk...is this sustainable to keep going down this direction and following the status quo?"
— Nicholas Lin [15:13]
