Jimmy is a fantastic tutor. He helped me go from a 149 to a 156, scoring 2 points higher on the exam than on any of my PTs. Going from not being able to finish any section on the exam to finishing all of them just in time. His strategies make taking the LSAT a repeatable system to be successful come test day. Couldn't recommend him enough.

Jatin is a particularly knowledgable person with immense insights in whatever he is talking about. He is also exceptionally helpful and tries his best to go out of his way to understand your problem and find the right solution for it. Strongly recommended

I can’t thank Sachin enough for his support during recruiting. He was always approachable, encouraging, and willing to help at every step. He shared invaluable tips on networking, recruiting, and navigating the process with confidence. What stood out most was how much he enjoys helping others succeed. I’d strongly recommend him to anyone going through recruiting.

Jatin was incredibly helpful during my business school application and interview prep journey. He provided structured, honest feedback on my Ross application, helped me clearly articulate my story, and ran mock interviews that significantly boosted my confidence.

I highly recommend Abby as an MBA consultant! She was thoughtful, supportive, and genuinely invested in my application journey. With her background at Yale and Kellogg, Abby brought strong insight and credibility to every conversation. She helped me refine my resume, brainstorm and shape my essays, and polish my entire application. Her feedback was always constructive, detailed, and encouraging, making the process both effective and manageable. Thanks to Abby’s guidance, I was admitted to CBS and Yale SOM. I’m very grateful for her support and would confidently recommend her to anyone applying to top MBA programs.

I had the opportunity to work with Chris about four years ago through a coaching relationship, and the impact of that experience has stayed with me ever since. From the very beginning, Chris created a space grounded in trust, respect, and patience—one that allowed for real self-discovery rather than quick answers or surface-level fixes. What stood out most was his ability to thoughtfully challenge my preconceived ideas. He asked questions that made me slow down, reflect, and rethink long-held assumptions. Through that process, I gained deeper clarity on my values, my leadership approach, and the stories I was carrying into my work without fully realizing it. Chris doesn’t just coach the leader—he coaches the whole person. He understands that effective leadership is inseparable from identity, purpose, and self-awareness, and he brings that belief into every conversation. The insights and confidence I gained through our work together continue to shape how I lead, connect, and make decisions today. I’m deeply grateful for the time, attention, and genuine care Chris brought to our coaching relationship. If you’re looking for a coach who will meet you where you are, challenge you with intention, and help you grow in ways that truly last, Chris is exceptional.

He is an amazing coach and one of the best people to work with if you’re aiming for your dream university. His guidance and support throughout the university shortlisting and application process were extremely helpful. He is very knowledgeable, approachable, and genuinely cares about your goals. Highly recommended for anyone looking for the right direction

Chris Diller is the rare leader who bridges the gap between leaders, teams, and strategies for complex organizational challenges like Product Transformation and consistently shows up with genuine human connection. I worked with Chris as a Coach during several periods of critical organizational change, and he didn’t just help me navigate the 'process'—he helped me navigate my own development and career, and the emotional uncertainty that came with it. With his deep background in engineering and transformation, he understands the technical stakes, able to speak to engineers and executives alike, but his true superpower is his complete lack of ego. He creates a psychological safety net that makes you feel genuinely cared for, whether you are winning or stuck. The number of success stories I have from our time together is beyond Critical Mass. If you need a coach who models what 'servant leadership' actually looks like, Chris is the one.

Warm, supportive, mindset-first Working with Ollie felt like having a super smart PM friend who also happened to be my therapist, strategist, and hype woman. I came in burned out and doubting whether I was even “good enough” for PM. Session by session, she helped me rebuild my confidence, reconnect with what I actually enjoy, and turn messy experiences into a clear, compelling narrative. I left each call calmer, clearer, and with concrete next steps instead of just ‘motivation.’

Ollie completely leveled up my interview game. She walked me through a clear framework for each type of PM question (product sense, execution, strategy, cross-functional), and then we turned my experiences into sharp, memorable stories with numbers and impact. She also pushed me to think more like a hiring manager, which changed how I answer questions and ask them. After a few sessions, I started consistently getting “great storyteller” and “clear thinking and great communicator” feedback from interviewers, and finally landed a PM role after being stuck at the loop stage for months. Look no where if you’re looking for a breakthrough!
