How it started
Christian and Braylin are college sprinters (Texas Southern and Texas Tech) who met in high school and had no coding experience. They had built a following with track content and a Shopify store under the 3AK name, then built the app in about two weeks by prompting AI tools. Launched December 16, it made $10K in the first month and ~$70K in six months, driven by their organic track and field videos.
