Patient Personas
These are the people Canary is built for — patients stuck between a diagnosis and a home they can’t trust. Each persona maps a real clinical journey through the Canary integration.
Her 6-year-old son has persistent asthma. He’s on a daily inhaler plus a rescue inhaler. An allergist confirmed dust mite and mold sensitization through skin prick testing. Sarah can see mold in the bathroom grout — but doesn’t know if it’s throughout the apartment, in the walls, or in the HVAC system.
She called 3 inspectors from Angi. One never showed up. One immediately tried to sell her $8,000 in remediation before even testing. The third seemed legit — but she has no way to verify credentials, no reviews she trusts, and no idea if the price is fair. Household income is $140K. She has an HSA through her employer but doesn’t know mold testing qualifies as a medical expense.
Son’s ER visits drop from 4/year to 1. Daily medication reduced. Sarah finally has documentation to send her landlord. Total out-of-pocket after HSA: $0.
Chronic sinusitis for 18 months. Three rounds of antibiotics with no lasting improvement. His ENT suspects an environmental trigger but has no diagnostic pathway to test Marcus’s home. Surgery is on the table — a sinus procedure that costs $15K+ and requires two weeks of recovery. His home has high humidity (Austin summers), builder-grade HVAC, and has never had air quality tested.
Googled “mold testing Austin” — got 47 results ranging from $99 to $1,200. Can’t tell who is TDLR-licensed (Texas requires it) versus who is running a scam. Income is $95K. He has an FSA with $1,200 that expires in December — money he’ll lose if he doesn’t spend it. Doesn’t know mold testing qualifies.
Symptoms resolve without surgery. Marcus avoids a $15K procedure and 2 weeks of downtime. FSA funds saved from forfeiture: $1,200.
First pregnancy at 28 weeks. Her OB mentioned avoiding lead exposure — her building has original 1940s plumbing. A pediatrician she pre-booked also flagged lead risk during a prenatal consultation. She saw PFAS (“forever chemicals”) news coverage and is now anxious about every glass of tap water she drinks.
Found Tap Score online ($200+ DIY kit) but wants a professional to test properly and explain results in a medical context. Doesn’t trust herself to collect samples correctly when her baby’s health is at stake. Household income $180K. HSA balance: $4,200. Willing to pay anything for peace of mind — but overwhelmed by conflicting information online.
Lead exposure eliminated before birth. Baby arrives in a home with <2 ppb lead (vs. 18 ppb before). Both OB and pediatrician have the data. Priya stops buying bottled water: saves $1,400/year.
Severe eczema on hands and forearms for 2 years. Four dermatologists, countless prescriptions, patch testing inconclusive. His current dermatologist suspects a contact allergen or airborne irritant but has exhausted clinical options. His loft was renovated 3 years ago — new laminate flooring, paint, and furniture. He works from home, meaning 16+ hours of daily exposure.
Spent $3,000+ on dermatology copays and medications that don’t work. Tried elimination diets, switched detergents, bought hypoallergenic bedding. Nothing helps. Income $220K, max HSA contributions every year. He’s frustrated, exhausted, and willing to try anything — but has never considered that his “beautiful renovation” might be the cause.
Eczema resolves in 8 weeks. David stops $200/month in medications. After 2 years and 4 dermatologists, the answer wasn’t a cream — it was his floor. Avoided: $2,400/year in ongoing treatment costs.
The Pattern
Clinical visit → environmental nudge → HSA-funded test → data back to doctor → targeted fix → symptoms resolve. Canary monetizes every step.
The key insight: the healthcare platform already owns the moment a patient is most motivated to act — right after a diagnosis. Canary converts that moment into a $1,000+ journey that no competitor can replicate, because no competitor has the doctor relationship and the HSA unlock in the same platform.
