Foundational Roots
From a small seed of innovation, Sintelly has grown into a towering tree of support for many across the globe. Our journey began in 2017 when we established UP Studio Ltd., a company that provided services to various clients, building the capacity and capital needed to eventually focus on our product development.

Global Connection
In 2017, we launched the “Emotional Intelligence” app, a global educational platform with social networking features that connected users from the USA to India, the UK to Australia, and across Europe. The platform offered expertly written articles, quizzes for knowledge testing, and a forum for discussions among users about various topics, paving the way for a community of engaged learners.

Transformation and Innovation
The year 2019 marked a significant milestone, as we leveraged funding to upgrade and adapt the existing "Emotional Intelligence" mobile app into the educational platform "Sintelly." This transformation led to the release of three innovative products: two mobile applications for Android and iOS and a progressive web application.
