Insight
Rupa Health was acquired by Fullscript in 2023. Financial terms were not publicly disclosed, and this article does not speculate on valuation. Instead, it focuses on the technical and operational patterns that allowed Rupa to grow from early traction to a platform worth acquiring.
Written by Aravind Srinivas, early engineer at Rupa Health and Founder & CEO of HyperNest Labs. This article reflects public information and operator perspective—no speculation on confidential details.

At its core, Rupa Health simplified specialty lab ordering for practitioners. That meant connecting dozens of lab vendors, making ordering workflows intuitive, and giving clinicians confidence that results and billing would “just work”.
From an engineering perspective, this looked like a multi-tenant SaaS product with complex integrations, strict reliability needs, and a user base that grew quickly as more practitioners joined the platform.
As demand grew, Rupa experienced traffic spikes of 300%+ without the luxury of long maintenance windows. The platform had to stay up while new features shipped and the team scaled.
The engineering work focused on decoupling tightly-linked systems, putting strong observability in place, and creating clear performance budgets. That combination made it possible to spot regressions quickly and keep core clinician workflows fast.
HyperNest Labs now helps founders apply these patterns directly to their own products. We embed as fractional CTOs and founding engineers to design the same kind of resilient, investor-ready platforms.
