👋 WELCOME — I’M IAN

I’m an ex-BCG consultant, NYU Stern MBA, founder of Custom Case Coach, and professional educator. Since I started coaching in 2020, I’ve run 5,000+ coaching sessions with 1,000+ candidates across 100+ countries and helped candidates secure 500+ consulting offers.

My goal is simple: to provide the highest-quality and most efficient consulting interview preparation possible.

My approach is simple: learn WHY & HOW — not just WHAT, and learn how to actually think like a consultant (instead of just memorizing frameworks). I want you to understand how to think through unfamiliar problems, identify what actually matters, and eventually perform without needing a coach beside you. I built Custom Case Coach by combining three things: my own recruiting experience, my training and experience at BCG, and what I have learned from 5,000+ coaching sessions with 1,000+ candidates across 100+ countries.

During my MBA at NYU Stern, I interviewed with eight consulting and technology firms and passed every interview round I completed. I ultimately joined BCG and withdrew from the remaining processes once I had committed.

But being successful in an interview and being able to teach someone else how to succeed are two very different things.

I’ve also built a large free resource library across PrepLounge, YouTube, and The Consulting Offer Blueprint. Instead of hunting through everything, use the topic map below based on what you are working on.

📚 WHY DO I COACH? BECAUSE I LOVE TEACHING

Long before I became a case coach, I was already teaching.

I’ve taught Economics, French, English, and Agile methodology. At NYU Stern, I found myself spending a huge amount of time helping classmates with consulting recruiting and case preparation. After BCG, I started coaching as a small side project in 2020.

That side project eventually became 5,000+ coaching sessions, and in 2023 I founded Custom Case Coach.

Today, coaching is my profession.

I have also delivered paid consultant training for firms including PwC UK and Kearney Australia, as well as consulting recruiting and case interview workshops for universities around the world.

-------------------------------------------------------------------------------------------------------------

💡 I DON’T JUST WANT TO SHOW YOU HOW I WOULD SOLVE A CASE

There are plenty of former consultants who can solve a case well, watch you solve one, and tell you what you did wrong.

That is not enough for me.

I fundamentally believe that we don’t go to school simply to learn a topic. We learn how to learn.

My coaching works the same way.

I don’t want to teach you the framework for market entry, the framework for profitability, or the answer to a particular brainstorming question.

I want to teach you how to approach an unfamiliar problem, understand what actually matters, structure it logically, and develop the answer yourself.

That is why so much of my coaching focuses on mindset shifts, first principles, and transferable problem-solving skills rather than memorization.

The goal is not for you to think:

“What would Ian do here?”

The goal is for you to know what to do yourself.

-------------------------------------------------------------------------------------------------------------

⚙️ COACHING IS ONLY ONE PART OF THE SYSTEM

Over the years, I’ve converted an enormous amount of what I used to teach live into a complete Custom Case Coach learning system.

Depending on your program, that can include:

100+ training videos, 300+ supporting resources, real interview and take-home cases, interactive simulations, case drills, fit preparation, applications support, networking guidance, and recruiting tools covering the journey end to end.

Why?

Because I do not want you paying me $399/hour to teach something you could learn effectively on your own.

I want our live sessions focused on the areas where expert coaching creates the most value:

Diagnosis. Targeted practice. Feedback. Correction. Reframing.

The parts that require a real person to understand what is holding you back and help you fix it.

My objective is not to maximize the number of sessions you book.

It is to create the most possible impact and value per minute, accelerate your progress, and get you to the point where you no longer need me.

That is what Custom Case Coach is built around.

-------------------------------------------------------------------------------------------------------------

🎥 KEEP LEARNING WITH ME

I EVERYTHING I DO IS TAILORED TO YOU AS THE INDIVIDUAL

My goal is not to have you complete the maximum number of cases or memorize the maximum number of frameworks.

It is to get you interview-ready in the least amount of time necessary.

That starts with diagnosis.

I want to understand what is actually limiting your performance: structuring, prioritization, math, exhibits, synthesis, case leadership, communication, fit, confidence, or simply an inefficient preparation process.

Then we focus on the few things that will create the biggest improvement.

I TEACH YOU HOW TO THINK LIKE A CONSULTANT

I fundamentally believe we do not go to school simply to learn a topic.

We learn how to learn.

My coaching works the same way.

I will not just teach you a framework for one case type.

I will teach you how to approach an unknown case successfully.

I do not want you relying on memorized buckets, rigid case types, or answers that only work when the interview looks familiar.

I want you to understand:

  • why a strong structure works
  • how to create one yourself
  • how to prioritize what matters
  • how to adapt when the case changes
  • how to communicate your thinking clearly

I want you to understand the WHY and HOW, not just memorize the WHAT.

That is why my coaching focuses so heavily on mindset shifts.

MY GOAL IS TO MAKE YOU INDEPENDENT

A good coaching session should not make you more dependent on your coach.

It should make you less dependent.

The objective is for you to leave with a better way of thinking, a clear preparation plan, and the ability to keep improving on your own.

Ultimately, my job is to give you everything you need to go it alone and succeed.

That philosophy is captured in the CCC Method: Diagnose → Reframe → Drill → Pressure-Test.

Interview Coaching
I had an interview for BCG Platinion in 3 days and had only just begun my prep. In just 1 session Ian completely transformed how I was thinking about both the interview and my prep - he focused me in on what was important (and, critically, how much I was wasting time on things I thought were important that weren't!). He also had a wealth of materials for me. In one session (including pre/post session materials), we covered: Crash course in casing (full walkthrough) Casing template sheet and how to organize a case from end-to-end How to handle tech brainstorming questions Mindset shift on understanding tech topics / industries Tech PE and Due Diligence Breakdown of major tech topics / terminologies Mindset shift in frameworking 5 Tech cases + 15 tech case prompts Thanks to Ian I feel much more prepared for the interview - and I can't believe how much time I wasted on lower value-add activities before meeting with him!

This package includes three, fully customizable 1 hour coaching sessions. Included for free with the coaching is a 100+ video course I have designed to provide you with offline training, learning, and deep-dive exercises - this course represents free coaching sessions and allows us to focus our live time on what can best help you.

*Ultimately everything I do is tailored to you as the individual. We work on what you need. This coaching package can be changed/modified to suit your needs - as an example, if you don't need resume/networking help, we can repurpose that time for frameworking / case leadership).

This package is designed to prime you for success in casing in the least amount of time possible. It is not about memorizing everything or being cased in x specific industry/case type. It is about me fundamentally changing your mindset to be prepared for anything that comes your way in the interview.

I fundamentally believe that we don’t go to school to learn x topic. Rather, we learn how to learn. Same with this package: I won’t teach you x case type, however I will teach you how to approach any unknown case type successfully.

But, don't just believe me when I say I provide a step change in your ability to change your thinking and get an offer.
