Market Entry When the Data Doesn't Exist

A market-entry deck arrives on a Tuesday. It is forty-two slides. Slide six is the TAM — a triangle, sourced to a research firm none of the partners in the room can name, projecting the addressable market at $14.3 billion by 2029. Slide nine is the competitive matrix, a five-by-seven grid in which the company being presented to has, by remarkable coincidence, more green checkmarks than any incumbent. Slide seventeen is the customer evidence: thirty-one interviews, of which twenty-eight indicated "strong interest" in the proposed offering. Slide twenty-eight is the five-year P&L. The numbers are rendered to the dollar.

We have read this deck, with different logos, perhaps two hundred times. It is the genre. And it is, in nearly every case we have seen, dishonest — not in the sense that anyone is lying, but in the sense that the document presents itself as evidence when most of what is in it is performance. The TAM is a fiction polished into a figure. The competitive matrix is a research-association exercise. The customer interviews were conducted by people the customers wanted to be polite to. The P&L was built backward from the IRR the room wanted to see.

The harder document — the one a corp-dev lead would actually want to forward to the CFO — looks different. It is shorter. It has more white space. It contains fewer numbers, and the numbers it does contain have ranges around them. It names what is not knowable in advance. And it proposes a way to find out, before the company commits the capital it would take to find out the hard way.

Why market entry is the worst place to pretend

Most major business decisions have at least some real data somewhere in the case. A pricing change has historical elasticity. A capacity decision has demand history. An acquisition has the target's audited financials, however massaged. A market entry, by definition, does not. The whole premise of the decision is that the company is going somewhere it has not been. The data, in the strict sense of the word, does not exist.

This creates a peculiar dynamic. Because the team cannot find real data, but the process demands a deck with numbers in it, the team manufactures numbers. The manufacture is not malicious — it follows the conventions of the genre. TAMs come from research reports; competitive intelligence comes from public sources; demand comes from interviews; financials come from a model that triangulates the three. Each step is defensible. The cumulative product is something the team itself does not actually believe — but the deck does not have a slide for "things we do not believe," so the disbelief lives in private side conversations and never reaches the board.

The TAM slide is the most expensive piece of fiction in modern business. Every executive in the room knows it. Nobody asks for it to be removed, because the room expects it.

We have, in engagements, asked the entry team — privately, in one-on-ones — what they would actually bet on, with their own money, regarding the size of the addressable market in year three. The numbers we get back are usually one-third to one-fifth of the deck. Sometimes one-tenth. The deck number is not the team's belief. It is the team's response to the demand for a number.

What the honest entry case contains

The honest version of the document has, in our practice, five components. None require fabricated precision. All require explicit acknowledgment of what is and is not known.

The first is a named-uncertainty list. Not "market risk." A list of the specific things that, if known with confidence, would substantially change the recommendation — and the team's current best guess on each, with a stated confidence range. "We believe the median enterprise customer in this segment spends between $40k and $180k annually on solutions in our category, with eighty-percent confidence. The deck assumes $95k. If the true number is below $60k, the entry case does not clear our hurdle." A board reading this knows immediately what to focus on. A board reading a TAM slide knows nothing.

The second is a reference class. The team identifies the five to ten most analogous entries it can find — by other companies, into related markets, in the last decade or so. It writes down, for each, what happened. What did the entrant project before going in? What did they realize? Where did they overshoot, where did they undershoot? What were the structural features of the entries that worked, and which of those features does this case share or lack? Bent Flyvbjerg's work on reference-class forecasting in megaprojects is the same idea, applied to a different kind of bet. The discipline transfers. The team that has done this work has, almost always, revised its forecast meaningfully — usually downward, sometimes upward, almost never unchanged.

The third is a structured pilot. Not "we will enter the market." Rather: "we will enter a defined segment, of defined size, with defined resources, over a defined window, and we will treat the result as information about the broader entry, not as the entry itself." The pilot is sized so that its failure is survivable and its signal is interpretable. Most company-killing entries are entries that skipped this step — committed full capital up front, on the strength of the deck, and discovered the deck was wrong in the same quarter they had finished building out the local team.

The fourth is a set of kill criteria. What would we see, by when, that would tell us to stop? In our experience this is the single most uncomfortable section of any entry document, because every constituency in the company prefers that no such criteria exist. The team that wrote the entry case does not want to write the conditions of its own failure. But the kill criteria are what convert the entry from a vow into a bet, and a board that approves an entry without them has approved a vow.

The fifth is an explicit theory of why we win. Not a list of "differentiators." A sentence — one — that names the specific advantage the entrant brings that the incumbents do not have, and an explanation of why that advantage will translate into share in this market specifically, not in the abstract. If the sentence cannot be written, the entry is not strategy. It is optimism.

What the dishonest case looks like, on the page

Set this against the genre deck described at the top of the essay. The genre deck contains a TAM (no range, no source the team trusts), a competitive matrix (assembled from public information, with self-flattering scoring), customer interviews (skewed by selection and politeness), and a five-year P&L (built backward from the desired outcome). It does not contain a reference class. It does not contain named uncertainties. It does not contain a pilot. It does not contain kill criteria. The theory of why-we-win is implied across multiple slides but never stated in a single sentence.

A board that approves the genre deck is approving the company's optimism. A board that approves the honest version is approving a bet, with stated terms. The decisions are different decisions, taken under different framings, and they produce different outcomes over time. We have watched companies that institutionalized the honest version exit markets earlier (saving capital), enter markets faster when the case held (because the pilot infrastructure already existed), and run their corp-dev function with meaningfully higher hit rates over a five-to-ten-year window.

The board conversation gets easier, not harder

Executives often resist the honest version because they expect it to be a harder sell to the board. Our experience is the opposite. The honest document reads more clearly to the board because it does not ask the board to pretend to believe things the board knows it cannot know. A board member who sees a $14.3 billion TAM projected to 2029 has two choices: nod (knowing it is theatre) or interrogate (knowing the interrogation cannot resolve). Either way, the board cannot productively engage. A board member who sees a named-uncertainty list with confidence ranges can engage immediately — by pushing back on the ranges, by suggesting additional analogs, by proposing a different pilot structure. The conversation that produces a better decision is the conversation the dishonest deck cannot have.

The honest entry document is closely related to the broader argument we have made about strategy as a series of bets. A market entry is the highest-stakes single bet most companies make outside of M&A. Framed as a forecast, it becomes a promise the team cannot keep. Framed as a bet, it becomes an experiment the company can run, learn from, and either scale or shut down on the basis of evidence the team committed in advance to respect.

If your next entry deck is being assembled around a TAM slide, a competitive matrix, and a five-year P&L — and the team building it would, privately, tell you they do not believe the numbers — that is the entry that most needs a different process. We help executives reframe entry decisions before the capital moves, while reversal is still cheap. The reframing is uncomfortable for about a week, and then it is the way the company has always done it.
