Welcome to Mergers & Inquisitions 4.0: Got Mobile?

Mergers & Inquisitions 4.0And… it’s here.

What started as a simple project to refine and clean up the site a few months ago is finally done today, and you can see the results by clicking here (if you’re reading this via email).

The last time we did a major redesign was more than 3 years ago, so it seemed like it was time to make another big change.

Yes, the site looks a lot better and there’s a giant video and set of buttons below it on the homepage now, but there are plenty of other benefits for you as well.

What’s New?

Let me break it down by category:

Revamped Design

While the old design “worked,” this new one is more professional and better highlights everything that’s actually available on the site – articles, interviews, web series, free videos, tutorial series, online courses, coaching, and more.

I won’t say that we “copied” the design of a similar, popular website in another market, but, um, let’s just say there was some influence.

While you may know what this site is all about if you’ve been a regular visitor for years, millions of new readers visit each year and don’t necessarily “get it” right away.

With the new homepage and the video with the obligatory shout-out to Per Se, it is impossible not to understand the site at first glance.

It’s also much easier to access everything here just by scrolling down a bit from the top of the homepage.

Better Categories for All Articles and Content

Over time, this site has moved away from pure investment banking coverage, and the original article categories stopped making sense a long time ago.

So I spent several days reorganizing everything (those were a fun few days), and you can see the result on the new Articles page.

Everything is now organized by industry (investment banking, private equity, corporate finance, etc.) and there’s a separate page for each one of those.

And then within each of those, there are more granular sub-categories (e.g., Investment Banking Groups & Regions –> Regions –> Europe).

Of course, there’s still a ton of content on investment banking since I spent a few years writing almost exclusively about that.

Going forward, though, at least 50% of the content here will be about other industries and the new category structure reflects that.

Free Tutorials, Courses, and More

Yes, I sometimes still get emails from readers wondering which company’s financial modeling course they should sign up for. Seriously?

So it is now blatantly obvious what we offer: the interview guide and networking toolkit, financial modeling training, industry-specific training, resume/CV editing, coaching, and more.

Over the past 1-2 years, we also released free tutorial series for the modeling courses and industry-specific modeling courses and you can also access all those tutorials via the links above.

Free YouTube Videos

I haven’t written too much about this one, but I’ve been gradually publishing free modeling-related YouTube videos over the past few months.

There’s one on Equity Value vs. Enterprise Value here (this one has generated the biggest reaction so far), one on how to calculate EBITDA, one on Depreciation on the 3 financial statements, and more coming soon.

These are not full courses or case studies or anything like that – they’re just short samples that answer specific questions we’ve received over and over again.

Since I am crazy and obsessive-compulsive, my long-term goal is to publish 5,000 free videos on YouTube, even if takes 25 years to get there.

NOTE: As stated above, these videos are NOT full courses and they’re not structured in an organized way – unlike the BIWS courses.

So no, I didn’t go on a weekend retreat into the magical forest of weed-smoking leprechauns and suddenly decide to give away all the modeling content for free.

These videos will help you a lot, but they’re not case studies that you can speak to in interviews or list on your resume/CV.

And if you already have access to the Premium/Advanced/Fundamentals course, I’m going to start adding these free videos soon – plus, you’ll also receive access to the Excel files, PDFs, and my written notes on each one of them.

Right now, the focus is on the “core technical topics” but eventually there will be industry-specific videos, videos on deal structuring and more advanced topics, and more.

Coming up next will be a series on equity investments (AKA associate companies) that explains what to do, simply, and clarifies the massive amount of confusion I’ve seen on this topic.

There will also be a set on Noncontrolling Interests under IFRS and GAAP, based on an accounting textbook I’ve been reading for fun.

(NOTE: Yes, I read accounting textbooks for fun. As you can tell, I have a very active social life and get invited to a lot of parties.)

…And It Really Works on Mobile Devices

Technically, the old design “worked” on smartphones and other mobile devices – it was readable, at least, and a different layout showed up if you were reading on one of those…

But this version is much better, i.e. it actually works.

It uses responsive design to automatically size the content appropriately depending on your screen size, so there are no shenanigans even if you’re using a much bigger/smaller screen at some point.

I still don’t have a solution for how to view massive Excel files on your smartphone, but at least you can now read everything and watch the videos more easily.

The entire BIWS site now works on mobile devices as well – which is more useful than it seems, since you can now take quizzes on your phone and read and watch on your phone, even if you cannot manipulate a 1,000-row Excel model on a 5-inch screen.

Browser Problems?

If you see any issues or bugs on this new design, please leave a comment with your findings or reply to one of my emails and let us know about it.

NOTE: If you’re using an ancient browser such as IE6 (released in 2001) or IE7 (released in 2006), you should really upgrade your web browser.

Even Google – a $300+ billion company – has now dropped support for some of those browsers, so we cannot possibly support them.

Dates on Articles!

On that note, I finally decided to give into the pressure and add dates to everything here, even going back to the first article published in 2007.

Just kidding.

That will never happen because I enjoy leaving dates off everything and saying “no” to this common request.

(I actually have reasons for doing this, based on data collected for email sign-ups and site engagement rates.)

But hey, keep trying and maybe one of these days I’ll give into the demands for dates.


That’s about it for now.

If you are using our modeling courses, you’re about to get a massive update soon – more quizzes, certifications, and transcripts, and a brand new massive bonus case study for the Oil & Gas course that goes beyond any other model covered on the site.

Comments, questions, feedback – you know what to do.

But please, try not to go crazy with those requests to add dates…

  1. Hi Brian, completely off-topic, but, what is your opinion about Bitcoin? Do you think it has a future?

    1. I’m bullish on Bitcoin – I actually have a large position myself (bought when it was at a lower price).

      Right now, it’s all speculation so the price could easily come crashing down. But I think Bitcoin and/or other virtual currencies could be hugely disruptive to the fractional reserve banking system and fiat currencies.

      And as you know, I am not exactly a fan of the Fed and other central banks, so I’m pretty excited by that.

  2. Dont like this new version , loved the old one

    1. Sorry to hear that. If you have specific suggestions or things you want to change, please let me know.

      1. Well i was settled on the old one, didnt feel the need for change.But if its for improved viewership and better mobile viewing then i can understand

  3. The mobile site is awesome.. I like the sharp fonts.. probably it would help if in the mobile site, each link does not open a new window but that’s hardly an issue.

    Overall, great work. It comes out beautiful in my galaxy note 3.

    1. Thanks! I’ll see if we can do that with the links… not sure if it’s possible but I will check.

  4. Brian,

    Excellent makeover of this site. Clean look, improved navigation and out-of-the-box design.

    Glad to see this. :)

  5. Brian,

    I’ve always had one issue you might want to know about.

    Every time I access the website on my iPhone 5 and go into the article section, I get the “banker blueprint” popup. This pop literally engulfs my whole screen, most of it being cut off (stretching outside my viewing capabilities), with no possibility of getting rid of it and actually exploring/reading the website via mobile. I am not able to scroll to close it, either. It comes a glitchy mess.

    And I’ve already signed up and purchased your premium course, so its not like I need this constant reminder.

    Just something that might help out your mobile viewers if you were unaware of the issue.

    1. Thanks for pointing that out – it should actually be disabled completely on mobile. It’s a software issue, so I’ve disabled it completely until we can put a fix in place. Let me know if it’s still appearing, but it should be gone now.

      1. Just checked – it seems to be fixed now. Thanks Brian!

        1. Thanks! Let me know if you see any other issues.

    1. M&I - Nicole

      Brian, welcome to M&I. I’m glad we got your attention. We’re your fans!

  6. Excellent improvements. Congratulations, Brian!

    1. Thanks for reading!

  7. Can’t wait for the oil & gas course

  8. Hi Brian,

    Keep up the good work. Good to see you keep growing.
    Having sections is one thing I always thought would make the website better and that’s a major improvement.
    As to dates, I think your idea to not have dates is great to keep things important regardless of the date.

    One thing though, was the font type always the same?

    (Not a huge fan of times new roman, and also an OCD person)



    1. Thanks! Yes, the font changed slightly. I might change that back because I think it’s a little harder to read as well.

  9. Hey Brian,

    The new site design looks really Awesome. Keep doing the good work that you do.

    1. Thanks for reading!

  10. Honestly, it looks like you just copied‘s design with a few minor tweaks…

    1. Not sure I see that one considering the layout and homepage are different… but I agree there’s more white space now.

  11. Congrats, it is in fact a great improvement for mobile users. As a follow up I could suggest even an app for iPhone/ android!!

    1. Thanks! I have thought about an app before, but I’m not sure what the benefit would be over a normal site that works on mobile.

  12. I just got done looking at the BIWS site on my phone and it’s awesome. I know what I’ll be doing with work downtime now. The auto sizing is really good because before I’d have to zoom around and resize myself to go over videos on my phone. Now I can just sit here and cruise haha.

    Thanks for the hard work on this. I look forward to the upcoming updates too for sure.

    1. Thanks! Glad to hear it.

  13. No offense, but I personally prefer the older version- this new design looks more like a website with tons of advertisements scatter around

    1. I hear what you’re saying – but do keep in mind, we don’t run any 3rd party advertisements… so anything here is something from us, not random links to 3rd party vendors. I’ll see if we can streamline this a bit, though.

  14. Very good surprise!

    And I like the idea about categories for articles. Before the redesign, it was difficult to find out some non-IB related articles, or any kind of specific topic, and we would have to search for The link that regrouped articles of a same topic/group/industry/…

    Nice job

    1. Thanks! Yes, hopefully it’e easier to find specific topics now (and search still works).
