Start from your real numbers: audience counts, the gap in your budget and what you can deliver. Have the AI turn them into three or four priced tiers with countable benefits, an event sponsorship proposal built on those tiers and a four-email pitch sequence for each prospect. You set the prices and check every figure; the AI drafts the wording.
The trap is the audience section. An assistant given no figures will invent flattering ones, and a sponsor who spots one wrong number stops trusting the rest. So the order of work matters: facts first, then tiers, then the document, then the emails. The examples use an invented charity fun run and family fair with about 3,000 people on site, so every figure here is illustrative.
A fact sheet the AI is not allowed to improve
Spend the first hour on one page of facts a sponsor would ask for, each tied to the record it came from: your registration export, the gate or volunteer count, your email platform and your social analytics. Anything you cannot source is written down as unknown, and the proposal says so.
| Fact | Illustrative figure | Record behind it |
|---|---|---|
| Registered runners and walkers | 1,050 last year; capacity 1,200 this year | Registration export |
| Visitors to the family fair | About 1,800 last year | Volunteer clicker count at the gate |
| On site this year | About 3,000 expected (1,200 plus 1,800) | Capacity plus last year's gate count |
| Email list | 4,200 subscribers | Email platform |
| Social followers | 6,500 across two accounts | Platform analytics |
| Age mix, dog ownership | Not recorded | Add both to this year's registration form |
Notice the last row. Nobody recorded age or dog ownership, so the sheet says so instead of guessing. A sponsor can live with "we will collect that this year and share it by [date]". They cannot live with a figure that collapses on a phone call. A short post-event survey fills these gaps for next year, and the event feedback survey tutorial shows how to write and summarise one.
You are helping an event organiser write a one-page sponsor fact sheet.
Use ONLY the notes below. Do not estimate, round up or add any audience
figure. Where a fact a sponsor would expect is missing, write NEEDS DATA
and name the record that would supply it.
Output a table (Fact | Figure | Source) and then a list of NEEDS DATA items.
Notes:
[paste your registration numbers, gate count, list size, follower counts]Keep the finished sheet where every later prompt can reach it. A ChatGPT Project or a Claude Project holds shared files and instructions, and a Gemini Gem (becoming a skill from November 2026) does the same job; pasting the sheet at the top of a plain chat works too. Wherever it lives, change a figure in one place only, so the proposal and all four emails quote the same number. The tutorial on where ChatGPT gets event facts wrong shows why that discipline matters.
Price the tiers from the budget gap, then test the ladder
Prices copied from a stranger's template reflect someone else's event. Work from yours: take the income you are sure of away from the cost of the day, add what the charity needs to keep, and what remains is the net amount sponsors must cover.
| Line | Illustrative figure |
|---|---|
| Cost of running the day | $38,000 |
| Registration income (1,200 at $22) | $26,400 |
| Stall fees (13 at $200) | $2,600 |
| Gap before any sponsor | $9,000 |
| Surplus the charity wants | $4,000 |
| Net needed from sponsors | $13,000 |
Sponsors also cost money to serve. Banners, bib printing and free entries (count each entry at the $22 ticket price) come out of what they pay, so the gross target is higher than the net one. Then decide the number of places and plan to fill about two thirds of them, because some prospects always say no. The plan must still clear the target at that fill rate.
| Tier | Places | Price | Direct cost to deliver | Left after delivery |
|---|---|---|---|---|
| Headline partner | 1 | $6,000 | $1,290 | $4,710 |
| Gold | 2 | $3,000 | $470 | $2,530 |
| Silver | 4 | $1,500 | $208 | $1,292 |
| Bronze | 8 | $500 | $64 | $436 |
Each direct cost is a short sum from your own quotes. Silver's $208 is four free entries at $22 ($88) plus a $120 water-point banner. The headline's $1,290 is 20 entries ($440), the finish-arch banner ($250), logo printing on the bibs ($250) and event-title signage ($350).
Fill ten of the fifteen places (one headline, one gold, three silver, five bronze) and gross income is $16,000, delivery costs $2,704 and $13,296 is left, which clears the $13,000 target with a small cushion. Lose a single silver and it drops to $12,004, about $1,000 short. Lose the gold and it falls to $10,766. That is useful to know before you start, because it tells you which prospects deserve the most effort.
Give the AI the budget, the places and your cost list, and ask it to build the ladder and show every sum. It is good at what-if questions such as "what if we sell no gold?". Language models do slip on arithmetic, though, so recompute two of its totals in a spreadsheet before trusting the rest.
My event needs $13,000 net from sponsors after the direct cost of
delivering their benefits. Build a four-tier ladder (one headline, then
gold, silver, bronze) with places and prices so that filling about two
thirds of the places meets the target. For each tier list 5 to 8 benefits
that are countable and dated, and estimate the direct cost of delivering
them using only the cost list below. Show every sum. Flag any benefit
that my fact sheet says I cannot deliver.
Fact sheet: [paste]
Cost list: [arch or zone banner $250, water-point banner $120, bib logo
print $250, title signage $350, sponsor-board logo $20, entry at ticket
price $22]Finish with a ladder test. Imagine a business with $1,000 to spend, one with $2,000 and one with $5,000, and ask which tier each would pick. If a prospect would land between two tiers with no obvious fit, move a price or add a smaller option. Steps of two to three times between tiers keep the choice easy to read.
Benefits a sponsor can count, and promises to leave out
Every line in a tier should be something you can count, date and deliver without anyone else's permission. "Brand exposure" fails all three tests. "Logo on 1,200 bibs, printed by [date], and in the footer of five emails to 4,200 subscribers" passes.
| Benefit | Headline ($6,000) | Gold ($3,000) | Silver ($1,500) | Bronze ($500) |
|---|---|---|---|---|
| Naming | Event title | Zone name (Pet Zone, Family Stage) | One of four water points | Logo on sponsor board |
| On site | Stall plus finish-arch logo | Stall, 3 by 3 metres | Banner at your water point | None |
| Free entries | 20 | 10 | 4 | 2 |
| Stage mentions | 6 | 3 | 1 | None |
| Emails to the list | Own feature, logo on all five | Feature in two | Two lines in one | Logo in footer |
| Social posts | 6 | 3 | 1 | Group thank-you |
| Goodie bag | Insert and logo on bibs | Insert | Insert | None |
| Category exclusive | Yes | Yes, in its zone | No | No |
| After the event | Report and call | Written report | Written report | One-page summary |
Category exclusivity is the benefit sponsors value most and organisers over-promise most. Offer it only where you control it. If stallholders or the venue's own caterer sell competing products, say which categories are exclusive and which are not, in writing.
Four promises to leave out: attendance guarantees (state your capacity and last year's actual instead), press coverage (you do not control it), sales results, and attendee data unless people agreed to share it when they registered. AI drafts love all four, so look for them when you read the first version.
| First draft from the AI | What you can actually write |
|---|---|
| Maximum brand exposure across all channels | Logo on all 1,200 bibs, the finish arch and the footer of five emails to 4,200 subscribers |
| Access to a highly engaged audience | A 3 by 3 metre stall at the family fair, open 10:00 to 15:00 |
| Guaranteed media coverage | Named in the press release we send on [date]; we cannot promise it is published |
Draft the proposal in five short blocks
One long prompt returns one long, bland document. Ask for the proposal a block at a time, each prompt carrying the fact sheet and the tier table, and you can check each block against its source before moving on.
- The offer in two sentences: what the event is and what you are asking for.
- The audience: figures only, each with its source and a line on what you did not record.
- The tiers: your table, plus one line on why each tier exists.
- The reporting: what a sponsor receives after the day and by when. The tutorial on sponsor reports and debriefs covers building it.
- The dates: decision date, payment dates, logo deadline and a named contact.
Two pages is enough, with the tier table on page two so it prints as one sheet. A one-page version for first contact is a close cousin of the AI-built media kit, so borrow its layout if you have one.
Write the section titled "Who you will reach" for a sponsor proposal.
Use only figures from the fact sheet below and name the source of each in
brackets. No adjectives that describe the audience (no "engaged", "loyal"
or "high-spending") unless the fact sheet contains data that supports them.
Finish with one sentence saying what we did not record and when we will
share it. Maximum 90 words.
Fact sheet: [paste]Here is the kind of first draft you may get back, and what to change in it.
Illustrative first draft: "Our event brings thousands of engaged locals together every year, including loyal supporters and high-spending families who love their pets."
Four problems sit in that one sentence. "Thousands" swaps the fact sheet's exact 2,850 for a vaguer, bigger-sounding word. "Engaged" and "loyal" have no measure behind them. "High-spending" has no spend data. "Love their pets" assumes dog ownership, which nobody recorded. The corrected paragraph reads:
About 2,850 people were on site last year: 1,050 registered runners and walkers and around 1,800 visitors counted at the family fair gate. Our email list has 4,200 subscribers and our two social accounts have 6,500 followers. We did not record age or dog ownership last year; both are on this year's registration form and we will share the results by [date].
The assembled two-page proposal, as a sponsor would read it
Put the five blocks together and the proposal reads like this, trimmed slightly for the page. Block 2 is the corrected audience paragraph above.
[Event name] sponsorship proposal
The offer. [Event name] is a charity fun run and family fair on [date], raising money for [charity]. We are looking for sponsors for 15 places, from one headline partner to eight Bronze places. Sponsorship covers the costs that entry fees and stall fees do not, and adds to what the day raises for [charity]. This proposal sets out what each tier receives, what we know about the audience and how we will report back.
The audience. [Corrected audience paragraph from above.]
The tiers.
Headline partner (1 place, $6,000): the event carries your name; stall and finish-arch logo; 20 free entries; six stage mentions; your own feature and logo in all five emails; six social posts; logo on every bib and an insert in every goodie bag; category exclusivity; a written report and a debrief call.
Gold (2 places, $3,000 each): name a zone (Pet Zone or Family Stage) with a 3 by 3 metre stall beside it; 10 free entries; three stage mentions; a feature in two emails; three social posts; a goodie-bag insert; category exclusivity within your zone; a written report.
Silver (4 places, $1,500 each): name one of four water points, with a banner; 4 free entries; one stage mention; two lines in one email; one social post; a goodie-bag insert; a written report.
Bronze (8 places, $500 each, cash or in-kind at retail value): your logo on the sponsor board and in the email footer; 2 free entries; a group thank-you post; a one-page summary.
The reporting. Within 14 days of the event you will receive a written report with the registered and finishing numbers, the gate count, the dates of every email and post that carried your name with the figures from our platforms, photos of your signage in place and a short summary of survey feedback.
The dates. Please confirm by [date] so banners can go to print on [date]. We invoice on acceptance, payable in two parts: half on signing and half 30 days before the event. Logo files in vector format are due by [date]. Contact: [name, role].
What the proposal leaves out matters as much: no adjectives about the audience, no promised coverage and no data handed over. Everything a sponsor can hold you to is a number, a date or a named deliverable.
Three prospects, three angles from one ladder
A good pitch starts from something true about the sponsor and shows the one tier that fits. Learn two facts from the prospect's own site or posts before you write a word, then paste them into the prompt.
| Prospect | Find out first | Tier and angle | First line of the email |
|---|---|---|---|
| Dog groomer | Which services they sell and whether they already post about dog-friendly events | Gold: name the Pet Zone, with their stall beside it | "We are adding a Pet Zone to the family fair and I would like it to carry your name." |
| Driving school | Whether they sponsor teams or run offers, and who the named contact is | Silver: a water point plus a first-lesson voucher in every goodie bag | "Four water points will carry sponsors' names where up to 1,200 runners and walkers stop." |
| Bakery or café | What they bake or serve in volume and whether they cater | Bronze, paid in kind: finish-line refreshments valued at $500 | "Could you supply the finish-line refreshments in return for a Bronze place?" |
In-kind deals need care. Count them towards your target only when they replace something you would otherwise buy, and write the quantity, delivery time and what happens if the supplier cannot deliver into the agreement. Last year's sponsors need a shorter note: thank them, share this year's numbers and ask for the call.
A four-email sequence with send days, written in full
Each email adds something new, which is what separates a sequence from nagging. The first carries the offer, the second a practical idea, the third a real reason to decide, and the fourth lets the prospect off the hook.
| Day | Job it does | |
|---|---|---|
| 0 | Pitch | One tier, one price, one ask |
| 4 | An idea | A specific way this sponsor could use the place |
| 9 | A deadline | A true reason to decide: places taken or a print date |
| 16 | Closing the loop | Permission to stop, and an offer for next year |
Write email 1 of my sponsor sequence for the prospect below. Use only the
facts supplied. Under 120 words, plain text, no exclamation marks, no
flattery. One ask only: a ten-minute call, or permission to send the
one-pager. Put any claim you cannot support from my facts in [square
brackets] instead of writing it.
My event facts: [paste fact sheet]
Tier to offer: [Silver, water point, $1,500, benefits list]
Prospect: [driving school]. What I found on their own site or posts:
[paste two or three lines, quoted]Here is the sequence for the driving school, as an illustration. The bracketed parts are the ones you fill from real facts.
Day 0. Subject: A water point with [driving school name] on it?
Hello [first name],
I run [event name], a charity fun run and family fair on [date] with about 3,000 people expected on site. [One real detail from their website or a recent post.]
We have four water-point places. Each carries your name on a banner where up to 1,200 runners and walkers stop, plus four free entries, a stage mention and your first-lesson voucher in every goodie bag. It is $1,500, and the benefits are listed on one page: [link].
Could we have a ten-minute call on [day] or [day]? Or reply "send it" and I will email the one-pager.
[your name], [event name]
Day 4. Subject: An idea for your water point
Hello [first name],
One thought, in case it helps: a "spot the hazard" card at the water point. Runners pick a card, answer in ten seconds and can enter a draw for a first-lesson voucher. Entries would carry a tick box so you only contact people who agree to it. We would supply the table and a volunteer; you would supply the cards and the prize.
The one-pager is here again: [link]. Does a call on [day] suit?
[your name]
Day 9. Subject: Water points: [two of four] taken
Hello [first name],
[Two of the four water-point places are now taken.] [Banner artwork goes to print on date, so I need a yes by then to include you.]
If the timing or price is the sticking point, tell me which and I will see what I can adjust. If it is simply not for you this year, a one-word reply is enough.
[your name]
Day 16. Subject: Closing the loop
Hello [first name],
I will assume the timing is wrong and stop chasing. If you would like first refusal on a place for next year's run, reply "next year" and I will write to you in [month] with the details.
Thank you for reading, whatever you decide.
[your name]
Only use the Day 9 facts if they are true. A fake deadline is the quickest way to lose a sponsor you will want next year. Send from a named person's own address, in plain text, one prospect at a time, and stop the sequence the moment someone replies. The deposit, cancellation and postponement thinking in the event venue contract tutorial carries over to the one-page agreement you send after a yes.
What each reply needs from you next
| They say | What it usually means | Your move |
|---|---|---|
| "Send me the details" | Interested, not committed | Send the one-pager within the hour and offer two call times |
| "Not this year" | Budget or timing | Ask when next year's marketing budget is set and diarise a note for then |
| "That is too much" | Poor fit, or the value is unclear | Offer the tier below, an in-kind option or two payments |
| "Who else is sponsoring?" | They want company | Name only sponsors who have agreed in writing; otherwise say places are open |
| Nothing after email 4 | Silence | Stop, record the date and invite them again next year |
| "Yes" | Decision made | Send the one-page agreement and an invoice the same day |
Ask the AI to draft a reply for each row, then read them as the sponsor would. The "too much" reply is the one to take most care over: it should offer a real alternative, never a panicked discount.
Six ways the AI's first draft quietly weakens the pitch
- Invented reach. A prompt without figures produces "5,000 followers" from nowhere. The NEEDS DATA rule in the fact-sheet prompt exists to stop this.
- Grand tier names. Platinum and Diamond tell a sponsor nothing. Name tiers after what they get (Headline, Zone, Water point) so the table explains itself.
- A flattering first line. "I love what you do" could be sent to anyone. One true detail from their own site is worth more.
- Benefits with no dates. "Regular social posts" becomes "posts on [dates]", or it is not a deliverable.
- Four emails that say the same thing. If email 3 repeats email 1, rewrite it around a new fact or drop it.
- A hidden price. Drafts often save the number for the call. Put it in email 1; sponsors would rather rule themselves out early than sit through a pitch.
A last check before anything is sent, and what follows a yes
Run this list on the proposal and on each email, and ask the AI to run it too, then compare notes.
- List every number in the document and tick it against the fact sheet.
- Recompute each tier's price, places and total in a spreadsheet.
- Check every benefit is countable and has a date or a quantity.
- Confirm you control each benefit without anyone else's permission.
- Check the sponsor's name, the contact's name and the tier named in the email.
- Look for the four forbidden promises: attendance, coverage, sales results, attendee data.
- Confirm the decision date and the print or payment dates are real.
- Send a test to yourself and open it on a phone.
When someone says yes, send a one-page agreement the same day: amount and payment dates, the list of benefits, logo format and deadline, and what happens to their money if the event is postponed or cancelled. Have a solicitor check your template once, then reuse it. After the day, report back with the numbers you promised; that report is also the first line of next year's pitch.
Sponsorship questions the proposal itself can't answer
How many sponsor tiers should a small event offer?
Three or four. Fewer than three gives a sponsor no choice, and more than four makes the comparison harder than the decision. Give each tier a fixed number of places, a price two to three times the one below, and at least one benefit the lower tier lacks. If two tiers differ only in logo size, merge them.
Can I give sponsors our attendee email list?
Not unless attendees agreed to it when they registered. Offer consent-based options instead: an opt-in tick box on the registration form, a prize draw whose entry form carries the sponsor's own marketing opt-in, or a message the sponsor writes and you send to your own list. Ask a data-protection adviser to check the wording before you promise any data.
Can AI find sponsors for me?
It can suggest the kinds of business that fit your audience and draft the first email, but treat every company detail it supplies as unverified. Look each prospect up yourself, find a named person on the company's own site or social account, and paste what you found into the prompt so the email rests on facts rather than guesses.
What if it is our first year and we have no past numbers?
Say so plainly. Give your registration target and today's sign-up count, and offer a first-year rate or a review point after the event. Sponsors accept a new event more readily than an inflated one. Keep the figures in one fact sheet and update it weekly so every email quotes the same current number.
