Rethinking course-building as a canvas, not a form Seturon is an EdTech startup in Luxembourg building a platform where companies, lecturers, and solo experts structure their knowledge into courses and sell them. I built the brand from scratch, the design system, six pages of the marketing site, and go-to-market materials. I redesigned the student and admin panels around the new system, including a full mobile experience for students. Outcome A course builder, rebuilt from a form into a canvas. I designed the course constructor from the ground up across two iterations: replacing a linear, step-by-step builder with a canvas-based editor inspired by Miro and FigJam. Measured with the team and with users (we were in direct contact with users, so we had real product data): ~30 min → ~5 min to build a course skeleton A 5–6-block non-linear course that took ~30 minutes to set up could now be sketched in ~5 minutes using drag-and-drop, dropdowns, and nested "Section" blocks. −42% support tickets related to the builder tracked on the team's ClickUp board by ticket topic, after the mechanics and bugs were fixed. ~34% of users created more than two courses In the first months after the MVP, it was a sign that the builder was something people came back to. 4–4.5 / 5 in public reviews The product is frequently praised as user-friendly and understandable even for non-technical users.
