How the AffinityRx team works with customers
Every AffinityRx customer works with a named account executive and a 24/7/365 human support team.
- Dedicated account executive. Runs the demo and onboarding, handles free bulk import from RxRelay, LifeFile or a direct pharmacy, and sources missing formulas, usually within 1–2 months.
- 24/7/365 human support. Real people around the clock, with replies in under 10 minutes, plus built-in AI support.
- Pharmacy vetting. AffinityRx vets every pharmacy for you; only 9% of the compounding pharmacies it reviews pass.
How the team works
The AffinityRx team works by three values: customer obsession, speed and simplicity.
- Customer obsession. Every decision building AffinityRx for clinics and telehealth brands is what is best for them; the same holds for pharmacies.
- Speed. Ship, get real-world feedback, iterate.
- Simplicity. Product, marketing, sales, operations and org structure all kept simple.
The values serve one mission: make medication sourcing faster, lower-cost and safer. Read the AffinityRx story for the timeline and roadmap, and about AffinityRx for what the company does.
