A prospectus is the document an event sends to a company that might fund it. It exists because the alternative is a long email, and a long email cannot be forwarded to a budget holder. Almost every failure of a prospectus is the same failure: it describes the event at length and the offer briefly, when the reader needs the reverse.
Who actually reads it
Usually somebody in marketing or developer relations, holding a budget and a shortlist of events competing for it. That reader is not deciding whether the event sounds pleasant. They are deciding whether it is defensible internally, which means they need a number of attendees, a description of who those attendees are, a price, and a list of what the price includes.
The second reader matters too: whoever the first reader forwards it to. That is often a finance approver who will never meet the organisers, so the document has to make sense without any accompanying conversation.
What it contains, in order
One page of what and who. The event in two sentences, the date, the format, the attendance figure, and who those attendees are by role. Honest numbers, including the year the event was smaller than hoped.
The offer. Every level, what it includes, what it costs. This is the section being looked for and it belongs early, not at the back. The structure behind it is on the tiers page.
What the money pays for. A short breakdown of where a sponsorship goes: catering, venue, recording, scholarship places. It converts a price into a purchase and it is the section that makes an unfamiliar event credible.
What is not on offer. Brief and useful. No speaking slots, no attendee lists. Stating it prevents the negotiation everybody dreads and signals that the event has thought about it.
Contact and deadline. A person, an email address, and the date after which the printing is committed.
Format, and the practical details
A PDF, because it is what gets forwarded and attached to an internal request. Somewhere between four and eight pages. Long enough to hold the tier table without cramming it, short enough that the offer is visible in the first scroll.
Assume it will be read on a phone, in a corridor, once.
Two versions are worth keeping. The full document, and a single page holding only the tier table and the contact details, which is what most conversations actually need. Two reference documents setting out the shape described here are available as PDFs: what a prospectus contains and sponsorship tiers and deliverables. The single page is also the one that survives being screenshotted into a chat message.
What to leave out: the history of the event, the personal story of how it began, a page about the host city, and stock photography of a crowd that is not this event’s crowd. None of it is read, and all of it pushes the offer down the page.
Keeping it honest
Attendance figures are the place where prospectuses quietly lie, usually by quoting registrations rather than arrivals, or by adding an online audience to a room. A sponsor who counts heads on the day and finds half the stated number does not argue. They simply do not return, and they mention it to peers.
The same applies to a first-year event with no figures at all. Saying so plainly, with a cap on what is being sold and a price that reflects the uncertainty, is a far stronger position than a confident projection that turns out to be wrong.
The tier table this document carries is on sponsorship tiers, what a sponsor receives in practice is on what sponsors get, and the pillar for the whole section is conference sponsorship. Where the money funds places rather than catering, scholarship funds covers how those are run.
Questions
What is a sponsorship prospectus?
The document an event sends to a company that might fund it, stating what the event is, who attends, what is for sale at each level, what it costs and who to contact. It exists so that a budget holder can forward it rather than paraphrase a conversation.
How long should a prospectus be?
Four to eight pages as a PDF, with the offer in the first scroll rather than at the back. It is worth keeping a single-page version too, holding only the tier table and the contact details, because that is what most conversations actually need.
What should be left out of a prospectus?
The event’s origin story, a page about the host city, and stock photography of somebody else’s crowd. None of it is read and all of it pushes the offer further down, which is the one thing the reader opened the document to find.
Should attendance numbers be in it?
Yes, and they should be arrivals rather than registrations. A sponsor who counts the room and finds half the stated figure does not complain, they simply do not come back, and they tell other people why.
What does a first-year event with no figures put in it?
The truth, a cap on how much is being sold, and a price that reflects the uncertainty. That is a stronger position than a confident projection, because a projection that misses is remembered and an honest caveat is not.
