Parallel Bio

Using the immune system to cure disease

Parallel Bio created a human 'immune system in a dish' to discover drugs and immunotherapies more likely to work in patients. Our platform has all of the same elements as a human immune system, meaning you can test drugs and vaccines as if you were testing them in actual patients from the start. The biggest reason why 95% of new drugs fail is that they were tested in mice - but with our human platform, pharma companies will know which drugs will successfully treat patients, speeding up the process and reducing the cost. To date our platform has successfully been used to test 12 drugs, and vaccines against 8 different diseases. The company is founded by Robert DiFazio, a former Stanford R&D director with a PhD in immunology, and Juliana Hilliard, a former System1 Biosciences R&D lead with an MSc in bioengineering, both of whom have led drug discovery programs for years.

Pharmie AI logo

Pharmie AI

The first AI pharmacy technician

Pharmie is an AI assistant for pharmacies. It can pick up calls, process prescriptions, handle insurance follow-ups, and even help upsell specific drugs and services. Pharmacies can get 50+ phone calls a day, and missing phone calls means lost revenue from filling prescriptions. Pharmacy workflows are complex and custom to each pharmacy's needs. Generic tools are not enough, which is why AI agents can handle tasks end-to-end that previously could not be automated. We are constantly evolving Pharmie to become a suite of agents that supercharge your pharmacy. In the future, pharmacies will evolve into patient care centers, bridging the gaps in access caused by today’s overburdened healthcare system. Successful pharmacies will use AI to optimize their operations, resulting in a higher quality patient experience traditional pharmacies cannot match.
