Executive Summary Prompts for Competitive Analysis
Compressing a competitive analysis is arithmetic, and a model is good at it. Deciding what to do about it is not arithmetic, and the brief format has a slot for it anyway. So the recommendation arrives in the same flat voice as the dates and the figures, written from nothing you supplied. Nothing on the page separates the two.
Compressing a competitive analysis is not deciding from one
A one-page brief does two jobs that look like one. It shortens an analysis, and it says what to do about it. The first is arithmetic: rank, cut, keep the dates. The second needs facts about your own company, and those are not in the analysis.
Ask for a brief and you get both, in one voice, at one confidence level. The deprecation date and the recommendation to act on it sit in the same paragraph, set in the same type. One of them can be checked in thirty seconds. The other cannot be checked at all.
This is not the usual problem of a missing source. Every other gap in competitive work closes by pasting something in. There is nothing to paste here. What a recommendation needs is cost, capacity, sequencing and appetite, and an analysis of a competitor holds none of it.
A ranking is the judgement your material supports
So the useful output is narrower than a brief and more useful than a summary. Rank the findings against one named decision. That ranking is arguable in the way a colleague’s ranking is arguable, and every line in it points at something you supplied.
Then ask what the material does not contain. That list is short, it is nearly always about you rather than about the competitor, and it is the closest thing to the recommendation you can honestly get from a model. It also tells you who to go and ask. Where the whole period rather than one decision is the subject, a competitive intelligence report is the document that takes it, and a brief is cut from that rather than the reverse.
Two questions to ask of any one-page competitive brief
What an executive summary needs before the analysis
Three inputs, and the order matters. The decision goes above the analysis, not after it. A model reading a long document answers whatever it was asked first, so a decision stated at the end arrives too late to filter anything.
The analysis, with a source and a date on every claim
- Where it comes from
- Whatever you have already produced: a teardown, a pricing comparison, a period of collected signals. A finished analysis already carries the dates a brief needs, which is the main reason to brief from one rather than from memory.
- What good looks like
- Claims in full sentences, each with the source it came from and the date that source was captured, in one message.
The decision, written as a question with a date on it
- Where it comes from
- Your own head, and it is worth two minutes. A decision is what somebody says yes or no to, by when. Not "understand their strategy" but "whether to fund X before Q2".
- What good looks like
- One sentence naming the choice and the date it has to be made, pasted above the analysis rather than left implied.
The reader, named by what they can approve
- Where it comes from
- Your own org chart. "The CFO" is a title; "the person who signs off headcount for next quarter" is what the brief actually has to persuade.
- What good looks like
- The role, what they control, and what they already believe, in a line. Two sentences is plenty.
- Then run it
- Send the analysis and the decision in one message, then read the brief against the analysis before you read it as a brief.
- Before the output leaves the building
- Point every sentence in the brief at a line in the analysis. The sentences that cannot be pointed anywhere are the recommendation, and writing that part is your job rather than the model's.
Most people skip the second input, and that is what turns a brief into a newsletter. “Understand their strategy” is not a decision. “Whether to fund a migration offer before the second quarter” is. The difference is that somebody can say no to the second one. Where the question arrives from another team, a written request brief is where that sentence gets captured before any work starts.
Writing the decision line, in one sentence
Prompts that turn a competitive analysis into one page
Three prompts, and the third one is a separate conversation rather than a final bullet. That is deliberate, and it is the hardest-won instruction here: an instruction asking for commentary after an output does not change the output.
The first pass, once you can name the decision the brief has to serve.
Turn the analysis below into a one-page brief for [AUDIENCE], who has [TIME] to read it and must decide [DECISION]. Structure: the conclusion first, then what changed, then why it matters to us, then the two or three decisions it implies with a named owner for each. Hard limits: 300 words, no heading longer than six words, and no sentence that would survive unchanged in a brief about a different competitor. Leave out anything that does not bear on the decision named above, and list what you left out at the end so I can check your judgement. ANALYSIS: [PASTE]
Use this instead of the one above when the decision is genuinely open.
Here is a competitive analysis: [PASTE]. The decision it has to serve is [DECISION], which [AUDIENCE] takes by [DATE]. Do two things and nothing else. First, rank the changes in the analysis by how much each one bears on that decision. One line each, with the source and the date it was captured. Say where two items are too close to separate. Second, under the heading WHAT THIS MATERIAL DOES NOT CONTAIN, list what somebody would need to know to decide, that is not in what I pasted. Include facts about my own company: cost, capacity, existing customers, who owns the work. Do not recommend anything. Do not name an owner. Do not invent a deadline.
Run this on a brief you are about to send, in a fresh conversation, as its own message.
Below is a brief, and below that is the material it was written from. For every sentence in the brief, print the sentence and then one of: SOURCE: the line from the material it rests on, quoted NOT IN MATERIAL Do not judge whether a sentence is reasonable. A sensible conclusion drawn from the material still gets NOT IN MATERIAL, because that is what I am looking for. At the end, give the count of each and list the NOT IN MATERIAL sentences on their own. BRIEF: [PASTE] MATERIAL: [PASTE]
The second prompt forbids three things by name: a recommendation, an owner, a deadline. Forbidding them works better than asking for caution, because caution is a tone and the prohibition is a format. A model told to be careful still names a plausible job title.
Cutting is the other half of the job, and it is where a word limit does its damage. A model cuts by generality, so the lines only your situation knows go first. Competitive sales call prep runs on a two-hundred-word limit and loses all four account-specific facts to exactly that.
Where an executive brief invents its own recommendation
We briefed a real analysis and read the result back against it. The material was three public sources on one competitor: two years of its annual filing, an earnings call, and its dated developer changelog. The decision was named in the prompt.
Claude Opus 5given a three-source analysis of one public competitor: two years of its annual filing, its most recent earnings call, and its dated developer changelog. The named decision was whether to fund a migration offer, taken by a CFO
2026-09-24
Bottom line. HubSpot has set a September 2027 enforcement date that forces every customer with a legacy integration into migration work, and it lands while their own upgrade rates are under pressure. A migration-assistance offer is worth funding at small scale for the window to mid-2027. What changed. On 15 September 2026 HubSpot announced end of support for v1-v3 APIs and both legacy public and private apps, enforced from September 2027. Legacy private app creation was removed from the account UI on 27 August. Pipelines API V1 sunsets on 4 December 2026. On the 12 August call management described net upgrade rates as pressured in the second half. Why it matters to us. Every integration-dependent account now has a dated, unavoidable project, and migration is the moment a switching cost gets paid anyway. Decisions. 1. Fund a migration-assistance offer for the Q4 2026 to Q2 2027 window. Owner: VP Marketing. 2. Build a target list of accounts running legacy integrations. Owner: RevOps. 3. Hold pricing through the window. Owner: CFO. What I left out. Roadmap items unrelated to integrations, and the AEO positioning change.
Checked against HubSpot's developer changelog and the deprecation notices on it
Every date and every figure is in the material and quoted correctly. Four things are not in the material at all. The recommendation to fund the offer, the scale of it, the three named owners, and the third decision about pricing. Nothing pasted mentions our prices, our costs, our capacity or one person at our company. All four arrive in the same flat voice as the deprecation dates. The closing line is the part worth sitting with: asked what it left out, the brief lists two omissions and none of the four additions.
Fabrication

2026-09-24
Bottom line. HubSpot has told its ecosystem in writing which capabilities it intends to compete on, and the integration surface is where that lands first. What changed. The 2025 10-K added three competitive factors: AI agents handling end-to-end workflows, a unified data platform with AI-powered data quality and enrichment, and AEO and AI-native marketing capabilities. It added two competitor categories, one of them AI-native CRM and workflow automation startups. It rewrote its own one-line description of itself to an agentic customer platform. Separately, end of support for v1-v3 APIs and legacy apps was announced on 15 September 2026 and is enforced from September 2027. Why it matters to us. They are building toward agent-driven workflows, and clearing the legacy integration surface in order to do it. Decisions. 1. Review our own agent and automation story against those three factors. Owner: VP Product. 2. Scope a migration path for accounts on legacy integrations. Owner: Engineering. What I left out. The upgrade-rate commentary and the net revenue retention line, neither of which bears on a product decision.
Checked against HubSpot's 2025 annual report on Form 10-K
The ranking moved, and the move is defensible. For a product reader the competitive-factors list is the most decision-relevant thing in the material, and the deadline drops to fourth. So naming the reader does real work. What survived unchanged is the invention. They are building toward agent-driven workflows appears in none of the three sources. A filing states what a company competes on, which is a different sentence from what it is building. Two owners are named again, and the closing line again reports only omissions.
Over-inference
Claude Opus 5handed the identical analysis and decision, but asked to rank the changes against the decision and then list what the material does not contain, with recommendations and owners forbidden
2026-09-24
Ranked against the decision. 1. End of support for v1-v3 APIs and legacy apps, announced 15 September 2026, enforced September 2027 - dated, unavoidable, and it reaches every account with an integration. 2. Legacy private app creation removed from the account UI, 27 August 2026 - narrows the workaround. 3. Pipelines API V1 sunset, 4 December 2026 - nearer and smaller. 4. Net upgrade rates described as pressured in the second half, 12 August - bears on the decision only through their appetite to make the migration easy. 5. The business description rewrite and the two added competitor categories, filed February 2026 - context, not timing. WHAT THIS MATERIAL DOES NOT CONTAIN. How many accounts in our base or pipeline run a legacy HubSpot integration. What a migration offer would cost to build and staff. Whether HubSpot ships a migration tool of its own before September 2027, which would close the opening. What our own import path does with a HubSpot workflow today. Who would own it: no name in this material is ours.
Checked against HubSpot's developer changelog and the deprecation notices on it
Nothing here is unsupported, and the ranking is arguable the way a colleague's ranking is arguable rather than invented. The gap list is the useful half, and four of its five lines are about us rather than about the competitor. That is the shape of the job. The material can rank itself against a decision. The decision needs facts that were never going to be in an analysis of somebody else.
The audit line only looks backwards
The brief ended by listing what it had left out. Two items, both real, both correctly judged irrelevant. It listed none of the four things it had added.
That asymmetry is built into the instruction. “Say what you left out” asks a model to compare the output against the input and report what is missing from the output. Additions are missing from the input, and nothing asked about those. So the request that feels like a safeguard audits one direction and is silent on the other.
A brief that is candid about its omissions and quiet about its inventions is worse than one that is candid about neither. The cut list reads as evidence that somebody checked. The third prompt is the check the cut list is mistaken for, and it has to run in its own conversation on the finished text.
| The part | Where it can come from |
|---|---|
| The facts, with their sources and dates | The analysis you pasted, and nowhere else. A model can lose these. It cannot add one. |
| The ranking against the decision | The analysis plus the decision, which is why the decision is an input rather than a preamble. |
| The recommendation, the owner, the deadline | None of your material. Cost, capacity and who is free next quarter are facts about you, and an analysis of somebody else holds none of them. |
Changing the reader changes the order, not the invention
Naming a different reader does real work. Briefed for a finance leader, the material led on the deadline and the pressure on upgrade rates. Briefed for a product leader, the same material led on the three competitive factors the filing had added, and the deadline dropped to fourth. Both rankings were defensible and they were genuinely different.
Both also closed with a recommendation and a named owner. The variable you supply moves the emphasis. The variable nobody supplies gets filled in either way.
The product brief added something else worth naming. It read the filing’s list of competitive factors as a statement of what the company is building. A filing says what a company competes on, which is a narrower claim, and the way to test the difference is to read that list beside the same period’s release notes and filings. A brief has no room for that step and no way to show that it was skipped.
Automating the competitive analysis an executive summary needs
A brief is only as current as the analysis under it, and an analysis ages from the day it is written. The gap between reading a competitor’s filing and briefing the exec team on it is often three weeks. In that time a price moves, a page changes, or the thing you are briefing on ships.
The dates are what protect you, which is why they are required on every claim above. A brief saying a competitor announced something on 15 September can be checked. The same brief without the date invites a question nobody in the room can settle, and the meeting moves on to something else.
No tool fixes the second half of this. The recommendation still comes from people who know what the quarter can absorb, and time to insight is a property of your own process rather than of your sources. Where a brief recurs on a rhythm, the quarterly competitive update is the document that carries it, and last quarter’s version is what makes this quarter’s readable.
Flares keeps a dated record of what competitors change across pricing, product, documentation and messaging. The analysis behind a brief is then current on the morning it is read, and every claim in it already carries the date it became true. What a competitor said in a filing, and what it means for next quarter, is still two separate reads — and only the first one can be kept fresh for you.
Between briefs, a weekly competitor digest is what stops the next one opening with something the exec team heard three weeks ago from somebody else.

The executive brief FAQ
What is an executive summary in a competitive analysis?
One page that states a conclusion, the change behind it, and what somebody has to decide. An executive summary is not a shorter version of the analysis. The analysis describes a competitor; the summary exists to move a decision, and anything that does not touch that decision belongs elsewhere.
Can ChatGPT write an executive brief from a competitive analysis?
Compressing the analysis is the half an AI assistant is good at, and the half people find tedious. The recommendation is the half it cannot do, because the facts that decide it are about your own company and are not in the analysis you pasted. Splitting the request in two is what makes the output usable.
How long should a competitive executive summary be?
One page, and the limit is doing real work rather than being tidy. A word limit forces you to rank, and ranking is the only judgement in the document your material can actually support. Give the limit as a number in the prompt, because a model asked to be brief is not.
Why does an AI brief always end with a recommendation?
Because every brief a model has ever read ends with one. The format carries the recommendation, so the slot gets filled whether or not anything in your material fills it. Removing the slot is more reliable than asking for more caution inside it.
What should a competitive brief leave out?
Anything that would not change the decision named at the top. That includes real findings, which is what makes it hard: a competitor's new integration is interesting and irrelevant to a pricing decision. Ask for the cut list, and read it, because it is the only visible trace of the judgement the brief made.
How do you stop a brief inventing an owner or a deadline?
Forbid both, by name, in the prompt. A named owner and a date are the two things a brief format expects and your material never contains. Left to itself a model will supply a plausible job title, and a plausible job title in a document going to leadership is worse than a blank.
Does changing the audience change the brief?
Changing the audience changes what gets ranked first, which is genuine and useful. What it does not change is the invented part. A brief written for a product leader and one written for a finance leader will lead on different findings and will both close with a recommendation nothing supplied.
Should a model write the recommendation at all?
Only where you have pasted the facts that decide it, which is rare. A recommendation needs cost, capacity, sequencing and appetite, and none of those live in an analysis of a competitor. A ranked list plus a list of what is missing gets a reader further than a confident closing paragraph.
Is an executive brief the same thing as a competitive intelligence report?
Different documents with different jobs. A brief covers one decision and deliberately ignores the rest, where a competitive intelligence report has to account for a whole period including the parts where nothing happened. Producing the second by shortening the first is the most common way both end up useless.
How do you brief an executive who reads only the first line?
Write the first line as the decision and the answer, then let the rest earn it. Most briefs open with context because the writer worked through the context first. A reader who stops after one sentence should still know what they are being asked and what changed.
What belongs in the brief and what belongs underneath it?
Quotes, sources and dates belong in the brief; everything a sceptic would ask for belongs one click below it. An executive brief template holds the structure and a pointer to the full analysis, which is what keeps the page short without hiding the evidence.
