Better Follow-Through for Every Student
We believe technology should strengthen the relationship between a coach and student, giving great coaches more time for judgment, teaching, and personal connection.
The Problem We're Solving
Coaches see important patterns during lessons, but there is rarely enough court time to review every match, connect every example, and document the next step.
Students leave with good intentions, then lose the details that made the coaching click. Coaches spend unpaid hours scrubbing video or stitching feedback across tools.
Dinkwize gives coaches one private workspace to review footage, shape their message, and deliver a Match Story the student can revisit. The coach remains the author; the product helps make that expertise easier to apply consistently.

Built by a Player, Guided by Coaches
The story behind Dinkwize.
Sean Sylvia
Founder
I built Dinkwize because the most valuable coaching insights often disappear between lessons. Players need a clear story they can revisit, and coaches need a sustainable way to create it.
As a health economist and technology researcher at UNC, I saw an opportunity to reduce the repetitive work around video review while protecting the human judgment that makes coaching valuable.
That is why Dinkwize starts with coaches and their existing students. Private assistance stays in the coach workspace; players receive only the Match Story their coach has reviewed and chosen to deliver.
