Swupnil Sahai Interview: Challenge Line Calls & Improve Your Game with Swing Vision

Will Boucek ยท February 11, 2023

In this interview, we chat with the Founder/CEO of SwingVision, Swupnil Sahai. Before creating the SwingVision App, longtime tennis player and fan, Sahai worked at Tesla.

The SwingVision App allows tennis players to record matches using AI for automated scoring, stats, and even line calls.

By simply setting their iPhone up behind the baseline, players are able to use this data to analyze and improve their game in real-time.

In this conversation, we talk about how the app can help you including:

  • How to challenge line calls so you don’t get cheated ๐Ÿ˜‰
  • Why using video analysis is the fastest way to improve your game.
  • What the differences are between different levels of players.
  • How to use the app to analyze your game and get better.

We also discuss how Swupnil got into tennis, what he thinks the future of SwingVision is, and why he thinks college tennis might be a gateway to making doubles more popular.
