About Brian DeChesare


Brian DeChesare is the Founder of Mergers & Inquisitions and Breaking Into Wall Street. In the late 90’s, he had the brilliant idea to start an Internet company in the midst of the dot-com bust. When that didn’t go so well, he retreated to Stanford.

He majored in computer science there, studied and worked in Japan, and then quit technology and decided to destroy the world by becoming an investment banker.

That plan came to end when he crashed his car into a tree while driving home from work at 4 AM (this was long before Uber and Lyft). This life-changing accident convinced him to quit investment banking and teach other students and professionals how to get in. Brilliant, right?

Since launching M&I and BIWS, he has lived all around the world, including in South Korea, Australia, Argentina, various other parts of Europe and Asia, and even boring little towns like New York.

Along the way, he has survived financial crises, actors dressed in pink rabbit suits, Sauron, and an existential crisis or three. You can get the full version of his life story below:

You can also read a few interviews and articles from Brian below:

He has also spoken at leading universities and business schools, such as Harvard, NYU Stern, Peking University, Stanford, the University of Maryland, the University of Virginia, the University of Pennsylvania – The Wharton School, and Yale.

You can follow him on Twitter here or Facebook right here.

About Mergers & Inquisitions

Maybe the market is terrible, and banks have slashed their hiring.

Or maybe the market is better, and hiring is up – but there’s also more competition, and it’s harder than ever to stand out.

But no matter what the market is doing, what’s stopping you from getting in and advancing on the job?


Context – knowing what it’s like to break into the industry and work there – separates those who thrive from those who merely survive.

Existing resources miss the mark because they’re not written by industry insiders and because they don’t give candid advice on what to do and what not to do.

Or, even worse, they “seem” authoritative at first… until you realize that a high-school or university student with no real experience wrote them.

Mergers & Inquisitions will help you to:

  • Learn what people in finance do from insiders who have worked in the industry – whether you’re interested in investment banking, private equity, hedge funds, equity research, corporate finance, private banking, sales & trading, or something else altogether.
  • Network your way in, craft a winning resume, and interview like a pro to land 6-figure+ job offers – without killing yourself or making embarrassing mistakes along the way.
  • Maintain your sanity, avoid layoffs, and get promoted more quickly.
  • Learn financial modeling via our comprehensive online courses (quizzes and certifications included), plus our free modeling tutorials and YouTube videos.
  • Get 1-on-1 help with your resume/CV, networking/interview prep, and other career questions via our resume editing and coaching services.
  • Entertain yourself with our exclusive web series, Cost of Capital.

All you need to do is take action based on what you learn here.


What Finance is Really About, and How You Can Break In

Finance is all about numbers, Excel, and rocket-science math, right?

To some extent, it is – especially in fields like quant hedge funds where in-depth analysis and programming skills are essential.

But it is also a social industry where your success depends on convincing people that you’re smart, you can do the work, and you’re likable.

In other words, breaking into investment banking is about persuading people to know, like, and trust you, whether that’s in your conversations with them, in your applications, in your interviews, or on the job.

Mergers & Inquisitions teaches you how to do that through detailed how-to articles, case studies, interviews, and questions & answers from readers.
