Proving sponsorship ROI so brands come back next year
16 June 2026 · 2 min read · Simple Sponsors team
The expensive part of sponsorship is finding a new sponsor. The profitable part is keeping one. A sponsor who renews costs you nothing to acquire, negotiates less, and vouches for you to others.
Renewals are decided by one question the brand asks internally: did that work? Your job is to make the answer easy to say yes to, with evidence you collected while the event was running.
Decide the metrics before the event
Ask each sponsor what result they care about, then measure that. A hiring sponsor counts conversations at the stall. A consumer brand counts samples handed out and coupons redeemed. A visibility sponsor wants photos and reach. Two questions before the event beat any amount of scrambling after it.
Assign someone to capture proof
One volunteer with a phone and a checklist: every banner, every stall, the crowd at peak, the sponsor’s session if they had one. Do it at the event because there is no later. The single most common renewal-killer is having delivered everything and being unable to show it.
The one-page wrap-up
Within two weeks, send each sponsor a short report: what they bought, what was delivered, the numbers you agreed to track, four to six photos, and one line on what you would improve next time. That last line matters; it signals a partner thinking about their result, not a vendor closing a file.
Ask for the renewal inside the report
End with the offer: next edition’s dates and a renewal option, ideally with first right on their current slot. The report proves the past; the closing line sells the future while the goodwill is warm. Organizers on Simple Sponsors can point renewing sponsors straight at the new listing, where rebooking is one application instead of a fresh negotiation.
