About Us

Jar is India’s leading Daily Saving app that helps people build strong saving habits—one small step at a time. Our goal is to make saving simple, rewarding, and truly life-changing. Founded in 2021 by Misbah Ashraf and Nishchay AG, Jar is a Bengaluru-based startup with one simple belief: saving a little every day in 24K Digital Gold can truly transform your future.

Today, 20 million+ Indians trust Jar as their saving partner. With flexible saving options—Daily, Weekly, Monthly, and Instant Saving—we have made it easy for everyone to save in their own way and withdraw anytime. We are one of the leaders in UPI autopay transactions, crossing more than 1 million transactions per day. In 2023, we expanded our vision with Nek, our jewelry brand crafted to bring together luxury and affordability, it has since surpassed ₹100 crore in revenue. 

We have a big dream of bringing “Har Ghar Sona”. Small, consistent savings are just the start. We’re here to walk alongside our users, helping Indians secure their financial future every step of the way.

Backed by Tiger Global Management, Arkam Ventures, and WEH Ventures, among others, we have raised $50 million+ in funding. In January 2025, we hit a huge milestone of becoming profitable. Now, we’re charging ahead, focused on sustainable growth and scaling impact.

And this is just the beginning!
