An anonymous business teaser can be written with AI if the model sees only a blind fact sheet: sector, rounded figures, reason for sale and highlights, with no names, places, customers or brands. A broker then edits the draft against a leak list. Structure it in eight blocks, from headline to the NDA step.
A teaser has two jobs that pull in opposite directions. It must give a buyer enough to want an NDA, and it must give nobody enough to guess who the seller is. AI is good at the first job when the facts are specific, and dangerous at the second, because it tends to include colourful detail it picked up from whatever you pasted. So the process is built to give it only safe facts, then check its work.
Five anonymisation rules before you write a word
- Replace exact figures with bands. Revenue of $1,873,400 becomes "$1.5m to $2m". Round profit too. Exact numbers act like fingerprints, especially in a small sector.
- Describe the place by category, never by name. Say "a mid-sized market town" or "a major commuter area" only if that is not itself identifying; where in doubt, leave it out and say "strong local presence".
- Never name customers, suppliers, brands or software. "A national retailer is the largest customer" may identify the business to its own staff. Prefer "no customer above 10% of revenue".
- Blur dates. "Founded 2009" becomes "over 15 years of trading". A famous year, a round number or an anniversary can point straight at the business.
- Keep the seller's own words out. Slogans, award titles and website phrases are the easiest things to search. Write fresh sentences from facts, not from marketing.
Write these on the front of every file. They apply to teasers, outreach emails and portal copy alike; for the outreach side, see AI buyer outreach and anonymous listings.
The template: eight blocks, filled in
A single page with eight blocks gives buyers what they scan for. Here is the structure, with an illustrative filled version for a fictional commercial cleaning business. Every detail is invented for the example.
1. HEADLINE (under 12 words)
Established commercial cleaning business with recurring contracts
2. SNAPSHOT (bulleted bands)
- Sector: commercial cleaning services
- Revenue: $1.5m to $2m
- Earnings after owner's salary: $300k to $400k
- Trading history: over 10 years
- Team: 15 to 25, mainly part-time
- Asking range: $1.1m to $1.4m
3. THE BUSINESS (3 sentences)
A cleaning company serving offices, medical practices and light industrial sites under recurring contracts. No customer accounts for more than 10% of revenue. Contracts renew on annual terms.
4. WHY IT IS ATTRACTIVE (3 bullets)
- Recurring, diversified income
- Experienced supervisory team in place
- Two service lines not yet actively sold
5. GROWTH ANGLES (2 bullets)
- Specialist cleaning for regulated sites
- Dedicated sales effort, absent for three years
6. REASON FOR SALE
Owner retiring; willing to stay six months for handover.
7. WHAT IS INCLUDED
Vehicles, equipment, contracts and brand
8. NEXT STEP
Qualified buyers can request an NDA to receive the full information pack.
Read it as a buyer would: sector, size, quality of income, upside, safe exit. It is specific enough to compare with other listings, yet there is no name, place, customer or date that identifies the seller. The details in block 5 should be checked with the seller, because "regulated sites" might reveal a niche.

Buy nowStep by step: building the teaser with AI
Step 1: Build the blind fact sheet by hand
You create it from the confidential file, applying the five rules. The assistant never sees the source file. A good fact sheet has 12 to 15 lines and fits on a postcard. If you use a business plan that does not train on content by default (ChatGPT Business or Claude Team, each with at least two seats), or a consumer account with training switched off, the risk is lower, but the blind sheet is still the rule, because the seller's agreement may restrict third-party processing.
Step 2: Ask for a draft with constraints
Write an anonymous teaser for a business for sale, using the template below and the blind fact sheet only. Rules: do not add any fact, place, customer, brand or year. Keep every figure as the band I gave. Use plain, factual wording; no superlatives such as "unique", "rare", "premier" or "leading". Maximum 350 words. After the teaser, list every sentence that contains a claim you were unsure about.
[paste template]
[paste blind fact sheet]
The final instruction yields a list of what the model guessed. In an illustrative output: "Unsure: 'Experienced supervisory team' (fact sheet says 'supervisors in place' but not their experience)." You decide whether to confirm with the seller or cut it.
Step 3: Edit for buyers, not for flattery
The draft will probably praise the business. Strip adjectives and keep nouns and numbers. A buyer trusts "no customer above 10% of revenue" more than "a diversified customer base". Move the most useful fact to the first line of block 3. Cut any sentence a competitor could use against the seller, such as an admission of declining margins, but keep honest facts that matter to a buyer; misleading omissions cause trouble later at due diligence.
Step 4: Run the leak check, then get the seller to sign it off
See the leak check below. The seller should read the final teaser and confirm in writing that they are happy that it does not identify them. Keep that email on file.
Before and after: a draft that leaks and its repair
Here is an illustrative first draft from a model that was given a seller's About page as well as the facts (a mistake covered below). The leaking details are marked in square brackets afterwards.
Established in 2009, this award-winning family-run cleaning firm has served the town's offices and clinics for 16 years. Our largest client, a national bank branch network, provides stable income. With revenue of $1,873,000 and earnings of $352,000, this is a rare opportunity to take over a thriving business with a loyal team of 19.
The leaks: "2009" (exact year), "award-winning family-run" (searchable phrase), "the town's" (location), "a national bank branch network" (named category that identifies the customer), "$1,873,000" and "$352,000" (exact figures), "19" (exact team size). "Rare opportunity" and "thriving" are puffery.
The repaired version:
A commercial cleaning business with over 10 years of trading, serving offices, medical practices and light industrial sites under recurring contracts. No customer accounts for more than 10% of revenue. Revenue is in the $1.5m to $2m range, with earnings of $300k to $400k after an owner's salary. The business has a team of 15 to 25, mostly part-time. The owner is retiring and will stay six months to hand over.
Compare the two. The repaired version is shorter, contains seven facts a buyer can use, and offers nothing searchable. The lesson is that anonymising often improves a teaser, because it removes the vague praise that buyers skip.
A second example: a different sector, different risks
For a small financial adviser's practice, say, the risks are different. The identifying details are not equipment or customers but the adviser's qualifications, niche and client base. An illustrative safe teaser line: "A small independent advice practice with recurring fee income, around 300 client relationships, and no single client above 3% of fees." The leak check would flag "independent" plus a rare niche. Similarly, for an interior designer's studio: "A design studio working mainly on residential projects, with repeat and referral work accounting for most new enquiries." A named design style, a famous project or a signature product line would identify it at once, so keep those out and offer them after the NDA.
The rule is the same in each sector: the most distinctive thing about the business is the most likely thing to identify it, so describe its category and keep its signature for later.
Wording rules that make a teaser read like a serious listing
Buyers read dozens of teasers, and most sound the same. The ones that get an NDA request share a handful of habits, and each can be written into your prompt so the model follows them.
- Lead with the quality of income. Recurring contracts, repeat customers, low concentration and long relationships come before growth stories. A buyer paying for earnings cares first about whether those earnings will continue.
- Use the buyer's vocabulary. Earnings after an owner's salary, add-backs, handover period, assets included. If you are unsure which terms your buyers use, look at the questions they ask on calls and copy them.
- Say what is not included. Property, a vehicle the owner uses privately, a licence that does not transfer. Honesty at teaser stage avoids a collapsed deal at due diligence, and it signals that the broker is careful.
- Prefer a short sentence with a number to a long sentence with an adjective. "Contracts renew annually; 80% by value renewed last year" is stronger than "very strong customer retention", provided the figure is true and cleared with the seller. Check it before use, and keep it as a band if it is distinctive.
- Keep the tone steady. No exclamation marks, no capital letters for emphasis, no "once in a lifetime". If an adjective could appear in any listing, delete it.
Put the rules in the prompt as a short list. Models follow explicit rules better than a general instruction to "sound professional", and you can reuse the list across every listing.
Headlines: a short bank to start from
The headline decides whether a buyer reads the rest. Ask for twenty and pick two, using a prompt that names what it must contain (sector, one quality-of-income fact) and what it must not (area, brand, year). Illustrative examples that pass the leak check: "Commercial services business, recurring contracts, owner retiring"; "Established trade business with strong repeat income"; "Profitable service company, six-month handover offered". Illustrative examples that fail: "Award-winning family firm with 16 years in the town" (award, family, exact years, place); "Largest cleaner for the bank's branches" (customer category); "Rare chance to buy a thriving market leader" (puffery plus an unprovable claim).
Test your two finalists on a colleague: show each headline for five seconds and ask what the business does and how big it is. The headline that gets both answers right wins.
Handling the asking price in a teaser
Whether to show a price is a strategy decision, not an AI one, but the model can help you set out the options. Showing an asking range filters out buyers who cannot afford it and saves time; leaving it out may attract more enquiries but forces more early calls. A middle route is to show a multiple band, such as "asking in the range of 3 to 3.5 times annual earnings after an owner's salary", which gives a buyer a way to compute a figure without exposing exact earnings. Whatever you choose, apply it to the whole listing portfolio so buyers learn what to expect from you. Do not let the model state a valuation; an AI valuation is a guess, and why AI valuation tools can mislead brokers explains what they miss.
A third example: a retail business, from fact sheet to teaser
Illustratively, say a broker has a specialist retailer. The blind fact sheet reads: sector, specialist home goods retail; revenue $800k to $1m; earnings $120k to $160k after owner's salary; trading over 8 years; two part-time staff plus the owner; online sales about 40% of revenue; reason for sale, owner relocating; lease transferable; inventory included at a value to be agreed. The prompt is the same as before, with one change: "The seller's website is not provided; do not guess the product range beyond the sector."
The draft returns a teaser with a clear headline, "Specialist home goods retailer with a growing online channel", a snapshot of bands, and a business paragraph. Two edits are typical. First, the model wrote "boutique shop in a vibrant shopping street", which is invented, so it goes. Second, it described the online share as "rapidly growing", which the fact sheet does not say; replace it with "about 40% of revenue". The leak check flags "relocating", since a seller who is known to be moving could be recognised locally; replace it with "owner moving on", which is true and less specific. The final teaser has a shorter business paragraph and is more believable for it.
Version control and sign-off
Treat the teaser like a contract draft. Name each version with a date, keep the approved version in one folder, and never edit a published copy; create a new version. A simple sign-off sequence works: broker drafts and runs the leak check; a colleague reads it cold and tries to guess the business; the seller reads and confirms in writing that they are content; the approved text becomes the only source for every portal, email and social post. If the seller changes anything, repeat the leak check, because their edits often put back the details you removed ("we do like to mention our awards").
If you keep your listings in a CRM, store the teaser version number against each campaign so you can see which wording each buyer saw. That helps when a buyer says "your listing said X"; you can check exactly what you published. What to compare in a business broker CRM lists the fields that make this practical.
A time budget for the whole job
Illustrative figures for one listing: building the blind fact sheet by hand, 30 minutes; drafting with AI and reading the list of unsure claims, 10 minutes; editing for buyers, 25 minutes; the leak check and a cold read by a colleague, 20 minutes; seller review and any changes, 15 minutes plus waiting time. About an hour and 40 minutes of your time, against perhaps two and a half hours when writing from a blank page and checking by eye. The saving is modest. The real benefit is that the process is the same each time, so leaks become rare, and a new broker in the firm can run it from the written steps.
The leak check: a ten-point list that a person runs
- No name of the business, owner, brand, product line or premises.
- No place smaller than a broad area, and none at all if the sector is rare.
- No exact year, anniversary or famous date.
- No exact revenue, profit, price, headcount or customer count. Bands only.
- No named customer, supplier, franchisor, landlord or software.
- No award, licence number, accreditation or membership that only one firm holds.
- No phrase copied from the seller's website, brochures or reviews.
- No description of the founder's story, family or career.
- Search test: paste three distinctive phrases into a search engine in a private window; none should return the seller.
- Staff test: would an employee reading this recognise their employer within ten seconds? If yes, rewrite.
Put your own initials and the date on the checked version. Items 9 and 10 are the strongest: they test what a real reader could do, which a model cannot. If you want a second reader, ask a colleague who has not seen the file to guess the business from the teaser. If they get close, revise.
Realistic mistakes and how they showed up
The helpful rewrite. A broker pasted an approved teaser into an assistant and asked for "more engaging" copy. The model added "in a prime location", which was true and identifying in a small sector. Prevention: add "do not add any information not in the text" to every rewrite prompt, and run the leak check on every output, however small the change.
The drifting copies. A teaser was reused across an email, a portal post and a social post, each rewritten by AI from the previous one. By the third copy, "over 10 years" had become "since the early 2000s", which was a different and more identifying claim. Prevention: every reuse starts from the approved teaser, never from a previous rewrite.
The over-anonymised teaser. A teaser so vague that buyers could not tell what the business did drew no NDA requests. Anonymising removes identifiers, not information. Keep sector, size bands, income quality, reason for sale and what is included.
What happens after the teaser works
A buyer who likes the teaser asks for more, and the next step is the NDA and a short qualification, described in qualifying buyers with NDAs and AI screening. After that, the buyer receives the information pack, which is covered in a confidential information memorandum workflow. The figures in the teaser's bands should come from properly recast earnings, so the numbers hold up when the buyer sees the detail; recasting financials and finding add-backs shows how that work is done.
How to check the teaser is doing its job
Track, for each teaser, how many buyers viewed it, how many asked for an NDA, and how many of those passed screening. A teaser that is viewed but rarely leads to NDA requests is probably too vague or priced out of range. A teaser that attracts many requests from unqualified buyers may be too enticing or too light on size, so add a band for earnings or an asking range. Change one block at a time and compare, and keep each version with its date so you can see what worked.
Anonymous teaser questions brokers ask
What is a business teaser?
A one-page, anonymous summary of a business for sale. It gives sector, size bands, reasons for sale and highlights without naming the business, so that buyers can decide whether to sign an NDA and receive the full information pack.
How long should a teaser be?
One page, usually 250 to 400 words, with a short bullet list of facts. Longer teasers risk leaking identifying detail and add little, because the information pack handles depth.
Should the teaser state the asking price?
That is a judgement call. Many brokers give a range or a multiple band to filter out buyers who cannot afford it, others leave price for the NDA stage. Whichever you choose, use it consistently and keep figures as ranges.
Can I put the seller's website into AI to write a teaser?
No. A model will often repeat phrases, award names or founding stories from the site, and each one can identify the seller. Write from a blind fact sheet that you built by hand.
