As a co-founder and CPO of the project, I was responsible for the complete design of the app interface, website, web version, promotional materials, and social media posts. I engaged in user development, validating hypotheses and tasks that eventually evolved into Renote features.

Additionally, I prepared pitch decks, presentations, and Invest Memos to attract potential investors to the project. My work also involved handling product and business metrics and setting up data analytics services.
