What you are buying
What you get
- 15 verified Decision Cases on Ecosystem Lock-in, one record per page.
- Each record states the fork, the options on the table, the choice, the reason the company gave, the money committed where the case states it, what happened at one, three and five years, and every source.
- The same records in five files: Excel, JSON, PowerPoint, Word, and PDF.
How to use it
- Open the Excel to compare records side by side and filter by company, date, or verdict.
- Cite a record in a memo from the Word or PDF page; the sources are on the page.
- Load the JSON into your AI workspace so the assistant reasons from verified cases instead of inventing them.
What it is not
- It is not a report. There is no introduction, no analysis across the records, and no recommendation.
- Each record says only what its source story says, so the writing is factual and brief, not narrative.
- If you want the argument, a Strategy Pack makes it; the casebook is the evidence behind it.
About the Ecosystem Lock-in Casebook
What is ecosystem lock-in? How do companies keep customers inside the walls, and what does it cost them? The knowledge of these strategies will help you glean insights, inspiration and actionable ideas. The Ecosystem Lock-in Casebook comprises 15 verified Decision Cases with dated outcomes from Hilton, Oracle, Salesforce, Shopify, Microsoft, Intuitive Surgical, Apple, Deere (John Deere) and 5 more.
Every record follows the same structure, which is what makes the casebook useful rather than merely interesting. You see when the fork came, what was on the table, what the company chose and the reason it gave, what it committed, and what happened at one, three and five years. Every fact is cited to its source, and where we offer a judgment, it is labeled as one. Across the 15 cases, which span 2003 to 2026, 14 carry dated outcomes; 12 of the decisions held, 0 were reversed, 2 held in part, and 1 are still too early to call.
Why it is worth your time
Keeping customers inside the walls works until the customers, or the regulators, notice the cost. These records show the switching costs each company built, the competitive and regulatory pressure they drew, and what retention and pricing power they delivered. Read them before you decide how tightly to hold your own customers.
Who reaches for it
Strategy and corporate development teams reach for it when a memo or a board paper needs real precedents rather than anecdotes. Consultants and advisors use it to put ecosystem lock-in examples with dated outcomes on a slide, with a source line under every number. Founders and operators facing the same fork want to see how it went for the companies that chose each way. And faculty, analysts and researchers use it as a structured, cited dataset instead of a reading list.
What it saves you
Assembling comparable precedents by hand is slow work. You have to find each decision, date it, read the filings and the coverage, pull out the same fields every time, and check every number before it goes near a slide. Here is what the casebook stands in for, and what each alternative tends to cost.
| Option | What you get | What it costs |
|---|---|---|
| Do it yourself | Your own research, one decision at a time, with fields that differ from record to record. | Three to four hours a case, so roughly 53 hours for 15 records. |
| An analyst-firm subscription | Sector benchmarks and briefings. Decisions turn up as examples inside reports, rarely as cases with outcomes. | An annual seat, commonly in the five figures, for coverage you cannot buy one decision type at a time. |
| A consulting workstream | A team assembles precedents for your case, once, on their timeline. | Weeks, and fees that start where this casebook's price ends by several orders of magnitude. |
| The Ecosystem Lock-in Casebook | 15 verified, comparable cases with dated outcomes and every source, in five formats, kept current. | $299, once. Less than an hour of any of the alternatives. |
How people use it
In the memo, you cite the records whose fork matches yours, outcomes and sources included, straight from the Word appendix. In the room, the PowerPoint gives you one record per slide with an action title and a source line, ready to drop into your own deck. In the model, you sort the Excel by verdict, horizon or capital committed and watch where the pattern breaks. And in your AI workspace, you load the JSON as vetted context, so the assistant reasons from verified cases instead of inventing them.

Questions
- What do I actually get in the Ecosystem Lock-in Casebook?
- 15 verified decision records of ecosystem lock-in decisions from Hilton, Oracle, Salesforce, Shopify, Microsoft, Intuitive Surgical and 7 more. Each one tells you when the fork came, what was on the table, what the company chose and why, what it committed, and what happened at one, three and five years, with every source named. You get it as Excel, JSON, PowerPoint, Word and PDF, plus the strategy templates for this decision type.
- How do I know the records are accurate?
- Every record is drawn only from the story it comes from and that story's sources; nothing is added from memory. Every fact carries a citation and a verbatim excerpt, and a number, date or quote the story does not contain fails a mechanical check. A second model from a different vendor then reads the record against the story, a third arbitrates any disagreement, and only records that pass all of it make the casebook.
- Why not research ecosystem lock-in examples myself, or ask an AI?
- You can, and it takes three to four hours per decision to find it, date it, read the filings and check the numbers, so 15 of them is roughly 53 hours. An AI is fluent on what a company announced and unreliable on what happened three years later. The casebook is $299, once, and every record has already been through the same fields and the same checks, which is what makes the set comparable.
- Is this a subscription?
- No. A casebook is a one-time purchase. When a story a record rests on changes, the record is re-verified and the casebook re-issued, and you get the new release. If you want every casebook kept current, the library license does that for a flat annual fee.
