Join Delfa to Cure the Deadliest Diseases on the Planet
Billions of people suffer from diseases we now treat as every day:
- Heart disease is the single biggest killer in the world.
- Alzheimer's disease and related dementia is the sixth leading cause of death in the US, and number one in the UK.
- Migraine is the second leading cause of disability worldwide.
To cure these diseases biopharma companies invest billions of dollars each year running clinical trials to test new treatments. $120 billion per year to be precise.
However, clinical trials are THE key bottleneck in developing new treatments to treat these conditions.

Delfa Builds AI Agents to Automate Clinical Trials
Delfa's first product is an AI agent to automate patient recruitment. Our AI agent uses voice, chat and text to prescreen, schedule and engage patients.
Patient recruitment is a massive, unsolved problem, with huge unmet demand. 80% of ALL clinical trials are delayed because of patient recruitment, and a third of the cost of a clinical trial goes into recruiting and retaining patients.
In Just 3 Months, Delfa is Already Having an Impact
- Live on 30+ clinical trials: heart disease, Alzheimer's, migraine, epilepsy and many more.
- Mid six figures in revenue with product usage growing over 300% month on month.
- Real customers who love us.
