About OneCase

OneCase is a wealth-tech platform built for India’s advisory ecosystem. We work with sub-distributors, MFDs, and small advisory teams to give them a single, clear view of client investments across mutual funds, insurance, and other asset classes.

Our platform replaces fragmented portals and spreadsheets with real-time visibility into AUM, flows, and client health, helping advisors make better decisions and build long-term trust with their clients.

We are built on trust, simplicity, and transparency. No hidden incentives. No product pushing. Just technology that helps advisors do the right thing.

If you want to build fintech products that matter on the ground in India, OneCase is a solid place to do that work.
