Aarush Kumar: Founder of ZextaOS

I am Aarush Kumar, the founder and chief product architect of ZextaOS. I founded ZextaOS with a single, non-negotiable objective: to free chess coaches and academy owners from the clunky, crash-prone, and predatory software platforms that have monopolized the chess education sector for the past decade.

Before building ZextaOS, I was on the front lines of chess education, actively working inside a growing chess academy as a Chesslang operations manager. I witnessed firsthand how outdated legacy tools drain tens of thousands of dollars in hidden fees, waste hours of administrative labor, and constantly humiliate coaches with server crashes during high-stakes classes.

I am also an active tournament-level competitor holding a peak 1900 Rapid rating on Lichess (handle: @aarushkumar09). ZextaOS was not conceived in a corporate boardroom by venture capitalists who don't know how the knight moves. It was built by a chess player and academy manager who lived through the exact operational chaos that academy owners battle every week.

Managing an academy with dozens of coaches and hundreds of students is high-pressure work. When you choose an academy management platform, you expect it to function like a high-performance operating system. Instead, using Chesslang felt like running a modern institution on 2014-era legacy scripts.

During my tenure managing academy operations on Chesslang, our coaching staff encountered compounding operational bottlenecks that cost hundreds of hours and severely damaged parent satisfaction:

I realized that legacy software companies had stopped innovating. They were resting on their early-mover advantage, collecting monthly per-seat rents while leaving academy managers and coaches to clean up the mess. That was the moment I committed to engineering ZextaOS from the ground up.

You cannot design high-level training tools for competitive players if you do not understand the game at a deep, intuitive level.

Competing at the 1900 Elo level means I understand:

• Calculation Fatigue & Time Trouble: Why students make blunders in specific pawn structures and how automated drill sets must isolate those exact tactical blind spots.
• The Scholastic Rating Plateau (1100 – 1600): Why generic puzzle rushes fail to help scholastic students transition from basic tactics to positional pawn breaks.
• Coach-Student Dynamics: How critical it is for a trainer to annotate a master game with colored arrows, candidate lines, and engine evaluations without the board lagging by a single millisecond.

ZextaOS was engineered with three non-negotiable principles that directly counter the shortcomings of legacy platforms:
