BlackBerry Lessons for Investors

The setup: the phone that ran business

In the late 2000s, if you carried a smartphone for work, it was almost certainly a BlackBerry. Made by the Canadian company Research In Motion, the BlackBerry had become the standard device for professionals, executives, and anyone whose job depended on staying on top of email. It was so central to how business people worked that it earned an affectionate nickname, the CrackBerry, for how compulsively users checked it. At its height around 2010 and 2011, BlackBerry was a genuine phenomenon.

Its strength was a specific, valuable thing: secure, reliable email and messaging, on devices with excellent physical keyboards, tightly woven into corporate IT systems. A company's IT department could deploy BlackBerry devices across the organization, manage them centrally, and trust that email would be secure and dependable. Executives loved the keyboards for firing off messages, and the encrypted BlackBerry messaging service was a real advantage for security-conscious firms. The whole package was built around the needs of the enterprise, and it fit those needs beautifully.

This produced what looked like a formidable moat: enterprise lock-in. Once a company standardized on BlackBerry, switching seemed expensive and unlikely. IT departments had built their systems around it, employees were trained on it, and the security integration was deep. Changing platforms across a whole organization is costly and disruptive, so BlackBerry's position with its corporate customers appeared entrenched. On paper, the switching costs were high and the moat looked durable. That kind of lock-in is one of the classic sources of durability described in identifying competitive advantages (moats).

BlackBerry lessons for investors: the moat that guarded the wrong door

The core of the BlackBerry lessons for investors is that its moat was real but protected the wrong flank. BlackBerry had built high switching costs at the level of the corporate IT department. The decision about which phone to use, however, was about to migrate somewhere its moat did not reach: to the individual employee.

When the iPhone arrived in 2007 and Android followed, they were aimed squarely at consumers, not enterprises. They had better web browsers, touch screens, and, crucially, a growing universe of apps. For a while this looked like a different market from BlackBerry's. BlackBerry served serious business users; the iPhone was for consumers who wanted a slick device for personal use. Many at BlackBerry took comfort in that distinction, believing the enterprise lock-in insulated them from consumer gadgets.

The distinction collapsed because the person choosing the phone changed. Employees bought iPhones and Android phones for their personal lives, loved them, and then wanted to use those same phones for work. This is the shift that came to be called bring-your-own-device: employees pushing their employers to let them use their own, better phones on the job. The pressure did not come from IT departments deciding to switch. It came from below, from individual workers who found the new phones simply better, and it flowed upward until companies had to accommodate it. BlackBerry's lock-in was built to stop an IT department from switching. It was useless against thousands of employees each making a personal choice and then demanding the company follow.

The failure point: a decision that moved

The heart of the failure is that the buying decision moved from the flank BlackBerry had fortified to one it had left open. BlackBerry had measured its switching costs correctly for the world as it was: enterprise IT standardization was genuinely sticky, and a rival trying to displace BlackBerry by selling to IT departments would have faced a hard fight. But the world changed shape. The relevant decision-maker became the employee, and the employee's switching cost to a personal iPhone was close to zero, because they were buying it anyway for themselves.

BlackBerry compounded the problem by being slow to respond, in a way that echoes the rise and fall of Nokia. Like Nokia, BlackBerry was strong in an older model, hardware keyboards and enterprise email, and underestimated how completely the touch-screen, app-driven consumer experience would come to define what people wanted from a phone. It kept building the devices its enterprise customers had historically wanted, while the ground shifted to consumer preference and apps. Its own strengths, the keyboard and the enterprise focus, became reasons it was slow to change. By the time BlackBerry launched a modern touch-based platform of its own, it was years late against entrenched app ecosystems, and its market position had already crumbled.

The failure was not that BlackBerry had no moat. It had a real one. The failure was that the moat guarded a door the attackers did not use. All the switching costs BlackBerry had built at the enterprise level did nothing to stop a consumer-led shift, because that shift bypassed the enterprise decision entirely and then dragged it along. Some of the deepest business risks are exactly this kind: not that a competitor overwhelms your defenses, but that the contest moves to a place your defenses do not cover.

There is a subtle reason this kind of threat is so easy to miss, even for a careful analyst. A moat that has held for years accumulates evidence in its own favor. Every quarter that enterprise customers stay locked in looks like proof the moat is working, which it is, right up until the moment the decision moves elsewhere. The data an investor watches, renewal rates, corporate contracts, IT commitments, all keep flashing green while the real threat builds in a place those metrics do not measure: the personal preferences of individual employees. By the time the danger shows up in the enterprise numbers, the shift has already happened. The lagging indicator confirms the moat right until it fails.

What happened, and the lesson

BlackBerry's collapse was swift once it began. Its market share fell sharply as consumers and then enterprises moved to the iPhone and Android. The company that had defined the smartphone for business users a few years earlier saw its handset sales evaporate. It eventually stopped making phones itself and pivoted to security software and services, surviving in a much smaller and very different form. The great consumer-facing franchise was gone.

The reusable principle is precise and unusually practical: the switching costs you measure may not be the ones that matter. A moat built on lock-in is only as good as its match to where the buying decision actually sits, and that location can move. BlackBerry measured the switching costs of an IT department correctly and was blindsided when the decision migrated to the individual employee, where its lock-in had no grip. The moat was genuine and it was aimed at the wrong target.

For a value investor, this sharpens how to think about switching costs, which are one of the most cited sources of a durable business. It is not enough to confirm that switching costs exist. You have to ask who actually makes the decision to switch, and whether that decision could move to someone the switching costs do not bind. A lock-in that holds one kind of buyer firmly can be worthless if a different kind of buyer takes over the choice. When you evaluate a company defended by switching costs, trace the decision to the person making it, and ask what would happen if that person changed.

Luck, skill, and what an investor should take away

Honesty requires naming what was foreseeable, and much of it was. The rise of consumer phones good enough for work, and the bring-your-own-device shift, unfolded over several years in plain view. BlackBerry's failure was less about being surprised and more about a mental model that put the enterprise IT department permanently at the center of the decision. That assumption was reasonable when BlackBerry rose and wrong by the time it fell, and the company held it too long. Skill would have been recognizing that the decision-maker was moving; the failure was a failure of imagination about who the customer would become, not simple bad luck.

The broader takeaway ties the failures in this module together. Kodak protected its best product, Blockbuster protected its best revenue line, Nokia defended the wrong basis of competition, and BlackBerry fortified the wrong flank. In each case the company had a genuine strength and a real moat, and in each case the strength became a blind spot because the world changed in a way the moat did not cover. In July 2026 BlackBerry survives as a software and security company, worth a small fraction of its former peak, a reminder that a switching cost is only worth what it protects. Past dominance is a fact about the past, not a promise about the future.

Where to go from here

BlackBerry closes a set of cautionary tales about moats that guarded the wrong thing. Read its closest cousin in the rise and fall of Nokia, and the margin-protection version of the same blind spot in why Kodak failed. To apply the lesson to companies you follow, use a Tenet watchlist and, when a business relies on switching costs, keep asking whether the buying decision could move to someone those costs do not bind.
