About mentr

Built for players ready to reach their potential

Most competitive gaming coaching is transactional. A player books a session, receives feedback, and is left to figure out the rest on their own. There is no continuity, no accountability, and no structured path to improvement.

mentr was built to replace that model entirely. The coaching space has long been dominated by one-off sessions that rarely translate into lasting improvement. We wanted to create something different a system modeled after personal training, where every student has a dedicated mentor, a structured program, and a clear measure of progress from start to finish.

The result is a program where your mentor is invested in your development across the full arc of a competitive set, your weaknesses are addressed consistently, and your improvement is tracked and documented at every stage.

Accountability over convenience
Sessions are twice a week, every week. Progress is graded at the start and end of every program cycle. There is no passive path through a mentr program.
Credibility without compromise
Every mentor on the roster is a verified competitor with a documented record. Credentials are never exaggerated and never fabricated.
Structure that matches the season
Programs run on cadences aligned to each title’s competitive season, so the curriculum is always relevant to what players are actually competing in.
Small cohorts by design
Enrollment is capped intentionally. Fewer students means more attention per player, stronger group dynamics, and a higher standard across the board.

As a Riot Partner and director of PROJECT PBE, Kai has a direct relationship with the top tier of the scene and a firsthand understanding of what separates players who consistently improve from those who plateau. mentr is the product of that experience applied systematically, built to give competitive players across multiple titles a structured path to improvement that the coaching market had never offered them.
