Stories of expertise, discovery, and becoming.

A genetic test can be a one-time purchase. The information and the promises attached to it can remain consequential for decades.

Teaching focus: Data value depends on durable permissions and trust, including during distress and ownership changes.

The founders saw weak listing photographs and tried a manual intervention. The case asks what that experiment could establish, and what it could not.

Teaching focus: Direct observation can turn a broad growth problem into a specific experiment. Keep the claim proportional to what the intervention actually tested.

A song looked like a simple digital file. Selling it required Apple to connect rights holders, consumers, software, and portable listening under terms each could accept.

Teaching focus: A simple customer experience can require a complex agreement among stakeholders. Map the permissions and incentives before assuming that better design alone will unlock adoption.

Babylon Health began with a compelling access thesis: a smartphone could make healthcare easier to reach. Patients could use digital tools, communicate with clinicians, and receive care without starting in a traditional clinic. The company’s ambition was larger than telemedicine. It described a digital-first model that could make high-quality care more accessible and affordable at global scale.

Teaching focus: When a company changes where it sits in the value chain, its revenue may keep the same name while its risks change fundamentally. Growth must be interpreted through the obligations attached to it.

An integrated model can look coherent in a diagram. Each new market still brings contracts, clinical relationships, claims, and capital requirements that must work together.

Teaching focus: Integration changes the organization's obligations as well as its opportunities. Each added capability needs evidence and capacity behind it.

The ambition was broad, but the first market had a clear deadline and deliverable. A school needed a finished yearbook, not mastery of professional design software.

Teaching focus: A narrow market can test a broad capability when the work has clear completion criteria. Requests for adjacent uses are evidence to investigate, not proof that every market is ready.

Giving someone a comparison tool does not establish that they will open it, trust it, or have a realistic alternative when they need care.

Teaching focus: Information changes outcomes only when people encounter it at a usable decision point and can act on it.

A missed appointment can look like disengagement from inside a clinic. From a member's home, the same event can reveal a service designed around the wrong assumptions.

Teaching focus: Trust becomes infrastructure when the organization funds the people, time, and continuity required to earn it.

A park needed funding and visitors. A television network needed programming. The 1954 agreement connected those needs without making construction or daily operations easy.

Teaching focus: A partnership becomes more credible when each participant can name the problem it solves for its own organization. Shared enthusiasm is less durable than complementary needs and clear commitments.

Publishing listings connected potential buyers and sellers. It did not tell either side whether a stranger would fulfill a promise. Reputation became part of the product.

Teaching focus: Reputation is designed, not simply collected. A feedback system must give people reasons to report accurately and help the next participant interpret what is missing.

A record documents care for one person. Research asks a different question across many people, and the distance between those purposes is where much of the work sits.

Teaching focus: Data become evidence through a defined question, careful curation, and validation appropriate to the intended use.

A team building a virtual world discovered a different setting for social interaction. The decision was what to preserve, not simply what to abandon.

Teaching focus: A product can change radically while preserving the human behavior the team understood best. Identify the repeat behavior before deciding which features to rescue.

An automated encounter still sits inside a care system. Forward's move from clinics to CarePods exposed the distance between scaling a device and sustaining a service.

Teaching focus: Automating a task does not remove accountability for the care journey around it.

By the end of the 2000s, large research programs were mapping the genomic changes that drive cancer. The scientific founders of Foundation Medicine, including Eric Lander, Todd Golub, Levi Garraway, and Matthew Meyerson, helped lead that work across the Broad Institute and major cancer centers. The emerging premise was powerful: tumors that looked similar under a microscope could be driven by different molecular alterations and might respond to different therapies.

Teaching focus: A discovery becomes a product when the people making decisions can receive, interpret, trust, and act on it. The infrastructure around an insight may be as important as the insight itself.

A prescription appears to end with a straightforward transaction: a clinician writes it, a patient visits a pharmacy, and the medicine is dispensed. Yet the price a patient encounters can vary by pharmacy, insurance status, benefit design, discount network, and negotiated rate. The same medicine may carry several possible prices that are difficult to see before reaching the counter.

Teaching focus: A free consumer tool may be only the visible surface of a multi-sided business. The decisive work is understanding who funds the value and who can withdraw access to it.

Finding a signal is an important scientific achievement. A screening system must also explain what happens to the people who receive it.

Teaching focus: Clinical usefulness belongs to the whole pathway from test to action and outcome, not to signal detection alone.

Amazon, Berkshire Hathaway, and JPMorgan Chase brought resources and reach. A shared intention still had to become decisions, authority, and a workable service.

Teaching focus: A coalition becomes useful when shared ambition turns into a specific problem, decision rights, and operating commitments.

A complicated check-in product contained a simpler social behavior. The founders had to preserve the appeal while removing much of the surrounding product.

Teaching focus: Subtraction becomes strategy when it strengthens a demonstrated user behavior. Simplicity alone is not evidence of value.

A health coach could solve a problem that another short physician visit could not. Iora's harder task was building a payment model that made that work possible.

Teaching focus: A payment model can make neglected work possible, but the team, measurement, and risk management still have to earn the result.

The meter made a number visible. The more difficult product was the sequence of support, action, and payment that followed that number.

Teaching focus: A connected device creates a channel for intervention. Its clinical and commercial value depend on what happens through that channel.

In 2011, separating DVD rentals from streaming made organizational sense to Netflix leadership. Customers were being asked to live with the consequences of that separation.

Teaching focus: Separate the intended strategic destination from the particular change customers are being asked to accept. Evidence against one implementation is not automatically evidence against the entire strategy.

The Game & Watch episode narrows Nintendo's long reinvention story to one decision: designing an engaging product around available, constrained technology.

Teaching focus: A constraint can sharpen collaboration and product coherence when it is tied to the experience users value.

Sean Duffy arrived at IDEO in 2011 as an MD/MBA student interested in primary care and chronic disease. With Adrian James, he began exploring how digital tools might support people between visits, where most decisions about food, activity, and health actually occur.

Teaching focus: Digitizing an intervention is not the complete innovation. In healthcare, the product often includes the behavior, evidence, human service, distribution, and buyer logic required to sustain it.

Primary care often asks patients to tolerate friction before care begins: long waits, inconvenient locations, rushed encounters, and fragmented communication. Physician founder Tom Lee saw an opportunity to design a different front door.

Teaching focus: A superior experience can be a strategic wedge, but every visible promise creates an operational obligation. The design and the business model must be evaluated together.

A more usable insurance experience can be valuable. It still has to operate inside a business that pays claims, prices risk, and carries capital obligations.

Teaching focus: Measure member experience and insurance economics separately, then test the mechanism that is supposed to connect them.

Changing the fiber was not as simple as changing a purchase order. Farmers, spinners, mills, designers, and customers all sat inside the decision.

Teaching focus: A value becomes operational when it changes a decision, a specification, or a relationship. The implementation reveals dependencies that a statement of purpose can leave hidden.

In September 2017, the US Food and Drug Administration granted De Novo authorization to reSET, Pear Therapeutics’ software-based treatment for substance use disorder. It was a category-defining achievement: software had been reviewed as a medical treatment, not simply offered as a wellness application.

Teaching focus: A milestone validates the question it was designed to answer. Do not let regulatory, clinical, technical, or fundraising success stand in for proof that the whole system will work.

Medication adherence is a persistent healthcare problem. A prescribed medicine cannot work as intended if it is not taken, yet clinicians often have limited visibility into what happens after the prescription leaves the office.

Teaching focus: Measurement is not the same as intervention. Before adding a new signal, identify who will act on it, what action becomes possible, and whether the person being measured sees that action as valuable.

Chris Gibson entered Dean Li’s laboratory at the University of Utah as an MD/PhD student planning to become a cardiothoracic surgeon. The group was studying cerebral cavernous malformation, or CCM, a rare condition in which abnormal blood vessels in the brain can leak and cause serious neurological harm.

Teaching focus: An unexpected result is not automatically a breakthrough. Its value depends on whether the team can distinguish error from evidence and then design a better way to learn.

The slogan was No Software. The actual offer was software delivered differently, changing who installed it, who maintained it, and what the customer had to trust.

Teaching focus: Changing how a product is bought and delivered can matter as much as changing its features. Lowering one commitment usually creates a new requirement for trust elsewhere.

Solving a problem for yourself creates insight, not automatic proof of a market. Shopify's transition makes that distinction concrete.

Teaching focus: An internal solution becomes a platform only when external customers can adopt it outside the conditions that made it work for its creators.

Tiny Speck had been built to make a game. Glitch was imaginative, social, and difficult to categorize. It also failed to become a sustainable business. When the company announced in late 2012 that the game would close, the obvious interpretation was that the venture had reached its end.

Teaching focus: When the stated product fails, examine the adaptations the team relied on repeatedly. The residue of the work may reveal a problem the team understands more deeply than the market it first pursued.

As a hospitalist and medical director for transformation at NewYork-Presbyterian, Michael Gao saw a recurring gap. The medical record did not always capture the full complexity of the patient’s care. Clinicians, documentation specialists, and coders could look at the same record from different professional positions and reach different conclusions about what belonged in the final claim.

Teaching focus: In complex organizations, value must be attributable as well as real. A product’s position in the workflow can determine whether a buyer can prove its effect.

Selling an aircraft addressed one financial problem and created a scheduling problem. The response depended on coordinated work at the gate, not merely a demand to move faster.

Teaching focus: Capacity can sometimes be recovered through coordination, but a performance target is inseparable from the operating conditions and safeguards that make it achievable.

A prospective customer could like the idea and still postpone the integration. The Collison brothers reportedly closed that gap by helping people begin immediately.

Teaching focus: An expression of interest is not adoption. Helping a willing customer complete the first useful action can reveal where the real barrier lies.

Long before COVID-19, remote care addressed an obvious need. A patient with an episodic concern might wait days for an appointment, travel to a clinic, or use an emergency setting for something that could be assessed by phone or video. The communication technology existed. The harder problem was turning a connection into recognized care.

Teaching focus: A crisis can remove the barrier to trial and validate an entire category. It does not decide which distribution model, workflow, or company will create durable value afterward.

The promise of easier blood testing was understandable. The governance failure was allowing claims about present capabilities to outrun evidence that others could examine.

Teaching focus: Scientific uncertainty is compatible with innovation. Misrepresenting what has been demonstrated is not.

The visible mechanism was a way to signal a problem. The deeper change concerned what happened next, who helped, and whether exposing a defect was rewarded or punished.

Teaching focus: A problem-reporting mechanism works only when the response makes speaking up useful. Tools, authority, support, and incentives must reinforce the same behavior.

A small internal experiment became a new company. Its early constraints help distinguish a useful option from a fully proven business.

Teaching focus: A small prototype can reveal an option before a business model is complete. Resource limits and governance still need explicit decisions.

Revenue can look like evidence that a health product works commercially. The more revealing question is whether the underlying payments are legitimate, durable, and accurately described.

Teaching focus: Reimbursement is evidence of a transaction, not automatic proof of clinical value or durable revenue quality.

Customers asked to see frames in person. An improvised apartment showroom offered a small way to learn before the company committed to permanent retail space.

Teaching focus: Keep the customer problem more stable than the channel. A small, reversible encounter can reveal what a distribution strategy leaves unresolved.

Members could avoid some of the commitments of a conventional office lease. Those commitments did not disappear. The operator had to finance and manage them.

Teaching focus: A flexible offer often transfers fixed commitments to the provider. Evaluate the duration and adjustability of obligations alongside the attractiveness of customer demand.

Opening the service to more kinds of video created opportunity and obligations together. The growth story is incomplete without the surrounding media system.

Teaching focus: Broadening use can reveal a platform's value, but it broadens the responsibilities needed to sustain that value too.

A flat subscription was attractive to some practices and a barrier to others. Changing the unit of payment changed the bargain on both sides of the marketplace.

Teaching focus: A marketplace's pricing unit defines its promise and redistributes risk between participants.
