Costimator was never meant to be a product — it began as a personal solution to a very real problem.

As an IES officer serving as Executive Engineer (Civil) in the Central Public Works Department (CPWD), Kushal Singh encountered the inefficiencies and frustrations of working with the Delhi Schedule of Rates (DSR) and Delhi Analysis of Rates (DAR). Preparing estimates and justifications was repetitive, time-consuming, and prone to human error — yet essential for every government construction project.

Instead of accepting the process as-is, Kushal set out to build a tool that would eliminate manual steps, intelligently link DSR with DAR, and automate complex calculations — all while generating audit-ready outputs in minutes. Initially built to simplify his own work, the tool quickly drew attention from colleagues, consultants, and departments. The demand wasn’t casual — engineers across the country were struggling with the same challenges.

It was at this point that Vinay Sharma, an IIM alumnus and seasoned entrepreneur, joined forces with Kushal as Co-founder. Vinay brought with him a rich history of corporate and business leadership — from setting up Airtel’s infrastructure network to founding successful ventures across gold, diamond, printing, and packaging industries. With deep business acumen and a sharp eye for market readiness, Vinay played a pivotal role in transforming Kushal’s internal tool into a robust, scalable SaaS platform ready for national adoption.

Together, they launched Costimator — not just as a product, but as a mission-driven platform built by engineers, for engineers.

Today, Costimator is used by professionals across India — not just for creating fast and reliable estimates, but for transforming how public infrastructure projects are planned, justified, and delivered. What started as a personal productivity tool has grown into a trusted solution for the entire construction estimation ecosystem.
