1. Inbound proposals from properties

Inbound proposals are the fastest source because the property has already identified your brand as a potential fit. They may include audience information, available assets, package options, and pricing.

The limitation is coverage. Your inbox reflects which properties have active sales teams and chose to contact you, not every opportunity that may suit your campaign. Compare each proposal against the same criteria—audience, geography, objectives, assets, timing, and budget—rather than only against other inbound offers.

2. Sponsorship agencies

Agencies can research opportunities, recommend a shortlist, negotiate terms, and support activation or measurement. They are most useful when a campaign is complex, the investment is significant, or the internal team needs additional expertise.

Agency fees and engagement models vary. Recommendations may also reflect the agency's relationships and areas of expertise, so brands should ask how the shortlist was developed and whether the agency considered options outside its existing network.

3. Direct outreach to properties

Direct outreach works best when you already know which team, event, venue, or organization you want to sponsor. A brand can contact the partnerships team, request current inventory, and discuss a custom package.

This approach provides control but takes time. Contact details, response times, package formats, and pricing practices differ by property. It is efficient for a focused target list and less practical for comparing a large market from the beginning.

4. Industry databases

Sponsorship databases help brands research who sponsors what, find decision-makers, review historical deals, and study competitor activity. SponsorUnited says its platform includes more than $45 billion in verified deal data and provides pricing benchmarks, market analysis, and creative research.

SponsorPitch combines searchable sponsor, property, agency, and deal records with a board for sponsorship pitches. Its published plans range from free to $221 per team per month when billed annually. Those figures are software subscription prices, not the prices of sponsorship packages.

Database coverage is useful for research and prospecting, but a record does not necessarily confirm that a specific package is available now. Brands may still need to contact the property for current inventory and pricing.

5. Sponsorship marketplaces

Marketplaces organize available sponsorships into searchable listings. They are useful when a brand wants to compare opportunities by factors such as category, audience, location, budget, assets, and timing before contacting each seller.

Anvara lists opportunities across sports, entertainment, live events, venues, and experiential activations. Listings include pricing and audience information, and brands can use the platform to make offers, sign contracts, pay, and track campaigns. Anvara's Starter plan is free for brands; advanced analysis, measurement, and managed sourcing are available through custom-priced plans.

Marketplaces improve visibility into listed inventory, but they do not represent every sponsorship in the market. A property or package that has not been listed will still require another source.

6. City and convention bureau calendars

City tourism organizations, convention and visitors bureaus, and municipal event calendars can reveal festivals, races, conferences, and community events in a target market. For example, Choose Chicago maintains a public calendar covering events across the city.

These calendars are free and helpful for local discovery, but they rarely include sponsorship contacts, assets, availability, or prices. Once you identify a relevant event, you will usually need to research the organizer and begin a direct conversation.

7. Trade media and category calendars

Trade publications report new leagues, events, venues, partnerships, and changes in brand spending. Category calendars and circuit schedules can also help a brand identify multiple stops within a series or recurring event format.

This source is most useful for ongoing market awareness and early research. Its coverage depends on the publication, geography, and category, and a reported event may not yet have sponsorship inventory available.

8. Existing partners' networks

Current partners can introduce brands to peer organizations, related events, or other rights holders in their market. These referrals begin with context and can reduce the time required to identify the right contact.

The reach of this source depends on the size and relevance of your existing network. It works well for expanding into adjacent opportunities, but it is less useful for a brand entering sponsorship for the first time or exploring an unfamiliar category.

How should brands combine these sources?

Start with a clear brief covering the target audience, market, objectives, budget, timing, and required assets. Then use each source for the part of the search it handles best:

• Use marketplaces to compare currently listed opportunities and prices.

• Use databases to research historical activity, benchmarks, contacts, and competitors.

• Use city calendars and trade media to broaden the list beyond paid platforms.

• Use referrals and direct outreach to reach specific properties or opportunities that are not listed.

• Use an agency when the campaign requires strategic, negotiation, or execution support.

Evaluate every option against the same brief. A consistent scorecard makes opportunities from different sources easier to compare and reduces the influence of presentation quality or sales pressure.
