Designing a sponsor prospectus with substantiated claims
The last prospectus said a premium audience of senior decision-makers, and nobody can now say where that came from.
The short answer
A prospectus works when each claim can be traced to a source and each benefit can be delivered. Build it from your inventory, your tiers, your pricing and your exclusions, then audit every sentence against the evidence you hold.
Sponsors judge a prospectus on fit and clarity. Specific, checkable facts about your audience and programme persuade more than adjectives.
What the prospectus contains
- Purpose and format of the event, in plain words and with dates.
- Audience facts you can source, such as past registration by role, region or organisation type, with the year.
- Programme shape and topics, marked as confirmed or provisional.
- Benefits, grouped by tier, each with its exclusions.
- Prices from your pricing method, with what tax and charges apply to be confirmed.
- Process: how to enquire, decision dates, what happens next.
How to test a claim
| Claim | Evidence needed | Safer wording if evidence is thin |
|---|---|---|
| A senior audience | Past registration by job level, with source and year. | Last year's registrants included the following job levels. |
| Attendance of a stated size | Last event's registered and attended counts, and what each means. | Last year, X registered and Y attended. |
| Leads or business results | None the organiser controls. | Omit. State the opportunity, for example a stand open to all delegates. |
| Media or social reach | Recorded figures with platform and period. | Describe the channels used without a reach number. |
| Endorsement by an authority | Written permission from that body. | Omit unless permission is in writing. |
Wording that avoids overpromising
- Say what the sponsor receives and when, not what they will gain.
- Mark provisional items clearly, such as speakers not yet confirmed.
- Use the same terms for benefits as the inventory and the agreement.
- Keep all delegate data benefits consistent with the decisions on personal data.
- Avoid superlatives such as the leading event or the largest audience unless a source supports them.
Review before release
Ask the programme committee to review the programme sections, the secretariat to check benefits and exclusions, and finance to confirm prices and payment terms. Ask your legal adviser to review any claims about the association's status, accreditation or endorsements.
Keep a short source note for every claim in a separate file, so the next edition is faster and the evidence is ready if a sponsor asks.
Worked example · Fictional example
A fictional association audits its prospectus claims
Fictional organisation and figures, for illustration only.
Majlis Fiktif Pengurusan Aset prepared its second prospectus. The first described delegates as C-suite decision-makers from across the region, and the secretariat found no data behind it.
The new draft used last year's registration counts by job level and organisation type, labelled with the year. It dropped any reach claim for social media, replaced a line about ready-to-buy leads with an open stand offer, and marked two keynote speakers as provisional. A source note listed where each figure came from.

Handle it in-house, or bring in help?
Your team can usually handle this when
- You hold clear records from past events and can cite them.
- The secretariat can keep benefits, tiers and prices consistent.
- A committee member can review the draft for accuracy.
Outside planning help earns its fee when
- The data you hold is incomplete or comes from several systems.
- Benefits, prices and exclusions are still being agreed across committees.
- You need the prospectus aligned with venue, programme and registration plans.
Want the prospectus aligned with the event plan?
An Event Blueprint can bring the programme shape, venue details, benefit structure and approval route into one planning pack that the prospectus draws from. A project lead can coordinate the committee reviews and the evidence behind each claim. Writing the sales message and approaching sponsors remain with your team.
Questions organisers ask
How long should a sponsor prospectus be?
Long enough to answer a sponsor's questions on audience, benefits, price and process, usually a few pages. Put detail such as order forms in the sponsor manual.
Can we publish audience figures from past events?
Yes, if you hold the records and state what each figure means, with the year. If the figures include personal information, check with your data protection contact first.
Should prices appear in the prospectus?
Many organisers include them, others share them on request. Either way, prices must follow your agreed method and state what is confirmed, such as tax or charges.
