Stop Guessing. Start Proving.

76% of sponsors can't accurately calculate ROI on their partnerships. They're writing checks and hoping for the best. Vonga gives your sponsors verifiable fan engagement data from physical merchandise — the proof they've been asking for.

The Sponsor ROI Problem

76%

Can't Calculate ROI

More than three in four sponsors report they can't accurately measure return on their sponsorship investments. They're investing on faith, not evidence.

Physical Engagement Data

Traditional merch activations generate zero verifiable engagement data. Logos on shirts are visible. But are fans actually seeing them? Interacting? Acting on them? Nobody knows.

Guesses

What You're Sending Today

Impressions estimates. Attendance figures. Logo placement photos. Sponsors nod politely but the data doesn't answer the question they're actually asking.

The Shareable Sponsor Portal

Your partnerships director doesn't build a report. They share a link. The sponsor logs in and sees everything in real time.

What Sponsors Can Do

  • Access their portal directly — branded link they can bookmark and check anytime without asking you for an update
  • Filter by date range — see performance for a specific event, month, or the full season
  • Export data — download their activation report for internal reporting or agency review
  • Share internally — send the portal link to their marketing team, CMO, or agency without giving them access to your full platform

What You Control

  • Which data each sponsor sees — isolate their activation data without exposing other sponsors' information
  • Portal branding — white-label the portal with your team's branding on Arena and Stadium tiers
  • How many portals you create — one per sponsor activation, or one per sponsor relationship, your choice
  • Access expiry — set portal access windows tied to contract periods

The Renewal Conversation Changes

Without Vonga

"We had 18,000 fans in attendance. Your logo was on 5,000 t-shirts. Estimated reach: 240,000 impressions across social posts featuring the event."

The sponsor politely nods. They're skeptical of "impressions." Their CFO is asking why they renewed. They open negotiations lower next year.

With Vonga

"Here's your portal link. You can see 2,847 verified fan interactions with your activation. 68% were in-venue. 32% happened after the game — fans at home or at work. 41% clicked through to your landing page. 12% engaged more than once."

The sponsor opens the link in the meeting. The conversation shifts from "did it work?" to "how do we scale it?" They renew at a higher rate because they can see the evidence.

Measurement in Action

Sponsorship Renewal Meetings

Walk in with a portal link, not a deck. Let the sponsor see real engagement data from their activation while you're in the room. The conversation is different when the proof is live.

Mid-Season Optimization

Know which sponsor activations are underperforming before season end. Adjust campaigns, update content, and fix issues while you still have games left — not after the contract year is done.

New Sponsor Pitches

Show prospective sponsors what their activation data would look like. Benchmarks from current programs make the pitch tangible — not theoretical. Close deals with evidence of what you can deliver.

Internal ROI Reporting

Your CMO and CFO want to know what the sponsorship program is delivering. Export the data. Build the internal deck. Prove that the partnerships team is generating measurable value.

Premium Deal Premiums

Teams that can prove fan engagement close sponsor deals at 15–30% higher values than teams offering estimated impressions. Verified data commands a premium. That premium pays for the platform.

Multi-Year Deal Modeling

Show sponsors what three years of growing engagement data looks like based on your trajectory. Multi-year deals are easier to close when you can show the ROI trend — not just a single-season snapshot.
