Baton Rouge's Chrysalis raises $400K to help patients track 'invisible illnesses
What's the deal? Baton Rouge healthtech startup ChrysalisDealroom has a profile for this one. Try Dealroom → has raised $400,000 from an undisclosed angel investor to build an app that gives users an AI-powered timeline of their personal health history. The tool connects medication side effects, daily symptoms, weather, and air quality to help people with chronic illnesses spot patterns. Founders Brent Martin and Brittany Martin aim to create a "cheat sheet" for doctors that shows what's working and how symptoms connect.
Why now? The couple developed the tool during a 12-week federal program, the TOPx HHS Tech Sprint for AI and Invisible Illness, run under the Department of Health and Human Services. Chrysalis was selected as a Phase 1 winner and is waiting to learn whether it will receive an additional cash prize.
What's the endgame? The app targets people managing complex, hard-to-diagnose conditions such as Lyme disease, long COVID, and autoimmune diseases. The beta is expected to include conversational health-history capture, condition and evidence tracking, clinician handoffs, and drug and supplement information.
The focus is personal: Brent's own Lyme disease took years to diagnose. "The reason invisible illness is invisible is because we don't know how to look for it sooner," Brittany told Technical.lyDealroom has a profile for this one. Try Dealroom →.
What's the role of AI? Chrysalis formally started in June 2025, focusing first on privacy and infrastructure. "AI is what helps us to take that unstructured data and make it more structured," Brent said, "and that's kind of the big opportunity that AI has as we move into how do we apply AI to healthcare."
Why Baton Rouge? Both founders have roots in Louisiana and family nearby. Brent has needed to travel outside the state for his own care, shaping an interest in tools that bridge access gaps for patients facing long journeys to appointments. The pair plan to begin beta testing in early 2027.
The signal: Chrysalis stands out in a thin local market — Louisiana startups raised just $6.9 million across 10 deals in Q3, with no reported Baton Rouge venture activity. Its federal recognition and rural-health focus align with state priorities: Louisiana has earmarked up to $20 million annually for five years for rural-health technology, with awards of up to $3 million per company, though first recipients were still under review in late October. For now, the federal boost and angel backing give an early-stage founder outside venture hubs a path to launch.
