+22% Brand Lift Through Multi-Channel Event Sponsorship

Digital event sponsorship with Rich Media, DOOH, audio and social activations

The challenge

A global technology company wanted to own the digital conversation around a major industry conference attracting over 50,000 in-person and virtual attendees. Their goal went far beyond a logo on a lanyard -- they needed measurable brand lift and thought leadership positioning across every attendee touchpoint, before, during and after the event.

We built a 360-degree digital sponsorship strategy combining Rich Media takeovers on key industry publications, programmatic DOOH inside the venue and surrounding areas via DV360, programmatic audio on streaming platforms, and social amplification to extend reach beyond the conference halls. Every activation was bought on a CPM basis with strict viewability thresholds, and every channel reinforced a single message: this brand defines the future of its industry.

How we delivered it

We orchestrated four channels simultaneously through DV360 and direct publisher deals, surrounding attendees at every moment and extending brand influence far beyond the physical venue.

Rich Media takeovers on industry publications

We negotiated exclusive skins, interstitials and expandable units on the homepages and article pages of the top 8 tech publications during event week. These high-impact CPM placements delivered 92% share of voice among the target audience, ensuring the brand dominated every editorial touchpoint.

Programmatic DOOH in and around the venue

Using DV360, we activated digital screens inside the conference center, hotel lobbies and nearby transit hubs with branded content synchronized to the event schedule. Geofenced CPM buying ensured impressions were served exclusively to screens within the attendee footprint.

Programmatic audio for attendee micro-moments

We deployed branded audio spots on Spotify, Deezer and podcast platforms, targeting attendees through geofencing and interest-based segments. These CPM-based placements reached professionals during commutes, hotel stays and between sessions -- moments when visual ads cannot compete.

Social amplification with real-time content

We managed sponsored posts, Stories and real-time content on LinkedIn, X and Instagram, amplifying keynote highlights and panel moments as they happened. CPM and CPE bidding drove 12K engagements while extending reach to the remote audience following the event online.

Why Kalithea delivered the difference

Precision geofenced activation

We set up geofences around the venue, partner hotels and transit routes to ensure DOOH and audio impressions reached confirmed attendees and industry professionals -- not random passersby. This independent, transparent approach meant zero wasted budget on out-of-target audiences.

Real-time creative synchronization

Our team updated creative messaging in real time to reflect keynote announcements, panel highlights and trending topics. This contextual relevance kept the sponsorship activation tied to the live conversation, boosting engagement rates 3x versus static creatives.

Earned media multiplier

The integrated, multi-channel approach generated significant organic sharing and press coverage. The earned media value reached 2.1x the paid investment -- a multiplier that only an independent agency, free from platform conflicts of interest, can consistently unlock.
