Hi, I'm Ratul Saha,
a product leader
from Singapore.

I'm the Chief Executive Officer of Quinence and a recent dad. When not playing with my kid, I work with my talented team to build products that delight.

I have a Ph.D. in Computer Science from the National University of Singapore.

What we build at Quinence


My personal email is [email protected]. For work-related queries, please contact Quinence.


I grew up in a small town in India. I was a Maths enthusiast from early on and was a National Mathematics Olympiad awardee.

I went for a dual degree in Mathematics and Computer Science — a rare combination for a bachelor's — at Chennai Mathematical Institute, a premier research institute in India.

While in college, I dove into theoretical computer science and, in particular, formal verification of distributed systems. I continued on that path when I joined as a Ph.D. student at the Computer Science department of the National University of Singapore.

After finishing my Ph.D., I started Quinence (called Getonchain then) as a Blockchain consultancy, leveraging my Ph.D. in distributed systems. I have worked with several Blockchain startups and large companies before expanding Quinence into a deep-tech product studio.

For the last five years, Quinence has built complex products for pre-seed startups to large enterprises. We have grown to a talented team of 10+, ventured into tech training, and continue expanding our horizon across Cloud-native products and Blockchain.

I live in Singapore with my wife and our infant. I spend every minute I can find playing with our kid, and sometimes work too.
