# 20-Min Connect With Varun with Varun Bhatia

> Open for a limited number of conversations each week. Could be a transformation program that's stalled somewhere between "everyone agreed" and "it's actually live." Could be a delivery or execution question you're working through, wherever you are in your career. Could just be that you want to connect and talk shop. All good reasons. 20 minutes, no deck, no pitch. Tell me a bit about what's on your mind when you book, and I'll come prepared to talk about that specifically. Execution. Deconstructed.™
