Fitt Insider Tech Stack

B2B platform connecting health and wellness merchants with patient networks

Internet News Pittsburgh, Pennsylvania 2–10 employees Privately Held

Fitt Insider operates a small, rapidly scaling team (2–10 employees, 10 new hires in the last 30 days) focused on merchant activation and patient-to-provider matching in health and wellness. The stack—React, TypeScript, Stripe, Adyen, Shopify, HubSpot, Klaviyo—reflects a transaction-heavy, marketing-automation-first business model, while active projects around HSA/FSA onboarding, clinic treatment fulfillment, and partner ecosystem scaling indicate a pivot toward employer/payer-adjacent revenue streams. Pain points around merchant engagement, subscription churn, and rapid scaling across franchises suggest the company is managing both supply-side (clinic/provider) and demand-side (patient/employer) network effects simultaneously.
