People Behind the Courses

Office Skills Accelerator courses are run by a Finnish company Itsellesi, founded by Jari Mustonen. The goal of all courses is to create learning experiences that combine the best pedagogy, a smooth user experience and quality content.

In 2020, amid global upheaval, my dual background in IT and psychology spurred me to create an online course on Word, Excel, and PowerPoint mastery. Fueled by a desire to transform learning into a captivating process, I assembled a team from Finland's top-notch education system. Our course launched in Fall 2020 and was a hit, with over 7000 participants praising its engaging and enjoyable approach. Feedback likened the experience to "learning to cast spells at Hogwarts".
In 2023, we launched an English version, aiming to broaden our reach. Our course offers practical skills in innovative ways, like utilizing pivot tables for data analysis or incorporating screen videos into PowerPoint, reflecting real-life scenarios.
