Gerard Rivera drawing on his experience as a pharmacist, working alongside pharmacy teams to ensure every patient receives the right medication, the right support, and the right financial outcome.

The first time I ever saw a document showing the business rules of a copay card, I knew I had a problem to solve that would save millions of dollars.
Pharma manufacturers have always gone above and beyond to keep patients on therapy.

For example, they might cover a patient’s out-of-pocket costs for six months when they really only needed to for two—enough time for the doctor to work on a prior authorization so insurance would cover it.

This happens because there are too many GTN Blind Spots.

I knew we could fix that.

Together with my co-founder Stephen Hom, we founded RIS Rx in 2020 to bring pharmacy-level insight to pharma executives managing billion-dollar budgets.
We wanted to help them create efficiency so that patients could stay on therapy.

In 2025, we’re on track to save our customers $1B in revenue leakage.

The key ingredient to our success is understanding the ins and outs of hashtag #patientaffordability and the hashtag #prescriptionlifecycle.

Before starting RIS Rx, it was my journey from the pharmacy floor, to being behind the bench with a foot in the corporate drug world that gave me a holistic understanding of the industry.

And today? We’re able to help with Real-Time Leakage Prevention with the goal of ensuring patients start and stay on therapy without disrupting the healthcare journey.

Grateful to everyone who has followed along.
