Mudo's transformation took place while both of these wishes were alive at once.https://joycema.ai/en/p/20261023-051554/https://joycema.ai/en/p/20261023-051554/Fri, 23 Oct 2026 08:00:00 +0000Jean-Claude Biver (A): The Reemergence of the Swiss Watch Industry.https://joycema.ai/en/p/20261023-5d58cf/https://joycema.ai/en/p/20261023-5d58cf/Fri, 23 Oct 2026 08:00:00 +0000A teenage boy writes down an enormous dream — and also writes down tidying his room, thanking people, and building lower-body strength. What draws me to Shohei Ohtani's goal chart is exactly this span: a distant wish, carefully placed into the life right in front of him.https://joycema.ai/en/p/20261023-26aa56/https://joycema.ai/en/p/20261023-26aa56/Fri, 23 Oct 2026 08:00:00 +0000This time, the prep material isn't a long case about a company. The professor gave us three questions: how I like to use AI, how it will change business over the next 6–18 months, and how I want employees to use it.https://joycema.ai/en/p/20261023-07645a/https://joycema.ai/en/p/20261023-07645a/Fri, 23 Oct 2026 08:00:00 +0000Thirteen Days — A Memoir of the Cuban Missile Crisis.https://joycema.ai/en/p/20261023-1eee13/https://joycema.ai/en/p/20261023-1eee13/Fri, 23 Oct 2026 08:00:00 +0000Starbucks Korea’s Tank Day: When the Machines Forgot.https://joycema.ai/en/p/20261023-d2fac9/https://joycema.ai/en/p/20261023-d2fac9/Fri, 23 Oct 2026 08:00:00 +0000The contracts were real, the products were delivered, and the cash came in. So one manager came to believe that booking revenue a few days early was fundamentally different from the more sensational financial scandals. This case makes you see again that time itself is part of the facts.https://joycema.ai/en/p/20261023-a300e3/https://joycema.ai/en/p/20261023-a300e3/Fri, 23 Oct 2026 08:00:00 +0000A company that sells distressed sneakers has grown to hundreds of millions of euros in revenue. The next question is how to keep growing while holding on to the reason customers wanted to walk in the door in the first place.https://joycema.ai/en/p/20261023-921fbc/https://joycema.ai/en/p/20261023-921fbc/Fri, 23 Oct 2026 08:00:00 +0000A pair of glasses you wear on your face every day can have the right prescription, a great look, and a badly balanced weight all at the same time. Breezm starts from this very specific discomfort and tries to reorganize how glasses are made and served.https://joycema.ai/en/p/20261022-a232dd/https://joycema.ai/en/p/20261022-a232dd/Thu, 22 Oct 2026 08:00:00 +0000Unspeakable: The Taboo Topics We Avoid and How to Talk About Them, and Note on Difficult Conversations in the Family Enterprise.https://joycema.ai/en/p/20261022-cf7614/https://joycema.ai/en/p/20261022-cf7614/Thu, 22 Oct 2026 08:00:00 +0000Mercado Bitcoin: M&A, IPO, or Series B?.https://joycema.ai/en/p/20261022-650c80/https://joycema.ai/en/p/20261022-650c80/Thu, 22 Oct 2026 08:00:00 +0000GeBBS Healthcare Solutions: Did You Ever Have to Make Up Your Mind?.https://joycema.ai/en/p/20261022-0989df/https://joycema.ai/en/p/20261022-0989df/Thu, 22 Oct 2026 08:00:00 +0000“A Marshall Plan for Africa”: James Mwangi and Equity Group Holdings.https://joycema.ai/en/p/20261022-e26a62/https://joycema.ai/en/p/20261022-e26a62/Thu, 22 Oct 2026 08:00:00 +0000class discussion of Nantucket Nectars: The Exit.https://joycema.ai/en/p/20261021-0f4c51/https://joycema.ai/en/p/20261021-0f4c51/Wed, 21 Oct 2026 08:00:00 +0000Why does a company that once made excellent products end up in trouble? And how does the person who takes it over reorganize the capabilities that still exist into a path that actually works?https://joycema.ai/en/p/20261021-788ca9/https://joycema.ai/en/p/20261021-788ca9/Wed, 21 Oct 2026 08:00:00 +0000Creating the First Public Law Firm: The IPO of Slater & Gordon Limited.https://joycema.ai/en/p/20261021-e23f12/https://joycema.ai/en/p/20261021-e23f12/Wed, 21 Oct 2026 08:00:00 +0000A country that can already land on the Moon, export software and build a digital payments system at enormous scale still has to answer a plain question: how do these capabilities turn into a life that most people can actually live?https://joycema.ai/en/p/20261018-1b61c1/https://joycema.ai/en/p/20261018-1b61c1/Sun, 18 Oct 2026 08:00:00 +0000In another class the same day, Frances Frei asks whether service is something you design. This class asks about control — the audit firm, the law firm, management: what role did each of them play? In this story, every piece of paper is in order. What's missing is the number behind the paper.https://joycema.ai/en/p/20261018-624265/https://joycema.ai/en/p/20261018-624265/Sun, 18 Oct 2026 08:00:00 +0000KLog.co – Charting the Course of its Future.https://joycema.ai/en/p/20261018-67ed6a/https://joycema.ai/en/p/20261018-67ed6a/Sun, 18 Oct 2026 08:00:00 +0000The last piece asked whether the silicon shield is a protection or a weak spot. This one swings the camera from wafers to a magazine. What gets taken for training here isn't production capacity — it's sentences.https://joycema.ai/en/p/20261018-574477/https://joycema.ai/en/p/20261018-574477/Sun, 18 Oct 2026 08:00:00 +0000Taiwan, Semiconductors, and a “New Cold War”?https://joycema.ai/en/p/20261017-c36bca/https://joycema.ai/en/p/20261017-c36bca/Sat, 17 Oct 2026 08:00:00 +0000The last piece, on Spyder, asked how ownership rewrites a company's value. This one asks something else: is service excellence designed, or improvised on a Friday afternoon? The story takes place on Halloween 2002 — at a bank that calls its branches stores and its customers fans, and that has just let its managers juggle in the lobby.https://joycema.ai/en/p/20261016-fbf58a/https://joycema.ai/en/p/20261016-fbf58a/Fri, 16 Oct 2026 08:00:00 +0000The previous piece, Nantucket Nectars, was about the seller — a company is worth the most in the year someone else needs you. This one is about the seller too, but the question flips over: the same company, with a different shareholder, isn't worth the same number. Not because the model changed, but because the people showing up to work next Monday changed.https://joycema.ai/en/p/20261016-25c797/https://joycema.ai/en/p/20261016-25c797/Fri, 16 Oct 2026 08:00:00 +0000New WOW at Equitable (A): A New Way of Working.https://joycema.ai/en/p/20261015-6ecc84/https://joycema.ai/en/p/20261015-6ecc84/Thu, 15 Oct 2026 08:00:00 +0000Now Is the Time for Courage: Five strategies to drive bold action amid uncertainty.https://joycema.ai/en/p/20261014-e8e3f8/https://joycema.ai/en/p/20261014-e8e3f8/Wed, 14 Oct 2026 08:00:00 +0000Axel Springer: Reinventing a Legacy through Global Acquisitions (A).https://joycema.ai/en/p/20261014-87b5fc/https://joycema.ai/en/p/20261014-87b5fc/Wed, 14 Oct 2026 08:00:00 +0000Roaring Out of Recession and Investing in Growth Through Uncertainty.https://joycema.ai/en/p/20261013-cec5b4/https://joycema.ai/en/p/20261013-cec5b4/Tue, 13 Oct 2026 08:00:00 +0000The last few pieces were all about how to build a company — Olay took its brand apart and put it back together, Belden transformed while profits were still rising, Bajaj guarded the gap between two purchases. This one runs the other way: the company has been built, and two founders in their early thirties have to decide whether to sell, to whom, and how. It's a story about "what it's worth," and…https://joycema.ai/en/p/20261012-bce359/https://joycema.ai/en/p/20261012-bce359/Mon, 12 Oct 2026 08:00:00 +0000Before class, I cast my vote for "fewer and clearer." Don't sell the brand. Don't chase 19-year-olds' acne. Cut the overlapping claims on the shelf and tell the red jar's story clearly. Swap "anti-aging" for a line that doesn't frighten anyone.
