Introduction Problem Statement
Preparing for the CASPer exam had long been a stressful and expensive journey for aspiring medical students. Traditional coaching solutions often cost upwards of $5,000, putting immense financial pressure on students. Beyond the steep cost, existing prep resources failed to replicate the real exam environment, lacked structured feedback, and offered little personalization.
Students needed something different an affordable, accessible, and intelligent platform that not only simulated CASPer-style tests but also analyzed their performance, tracked improvements, and gave meaningful feedback. The lack of such a solution created a gap in the EdTech market, leaving students with limited choices and subpar preparation tools.
CasperPrep approached Skywinds Solutions with a clear vision: to build a web-based SaaS platform that could replicate the exam, provide AI-powered insights, and scale quickly to meet growing demand. The challenge was to deliver this Minimum Viable Product (MVP) in just 30 days without compromising on functionality, scalability, or user experience.
Business Impact
A hypothetical case study showing how CasperPrep could launch an AI-powered SaaS exam prep app, gaining 500+ users and $20K revenue in its first month.
Breaking Barriers in EdTech Affordability
CasperPrep’s launch transformed the landscape of CASPer exam prep. By replacing costly coaching sessions with an AI-driven SaaS model, the app made preparation accessible to students who previously couldn’t afford high-ticket coaching. Within the first month, the platform attracted 500+ paid users and generated $20K in revenue proving that affordability and quality can coexist.
