Sample case study — TechSummit is a fictional conference used to illustrate how a typical B2B SaaS event uses Fotowall at scale. When we publish real-customer stories, we’ll clearly mark them.
The challenge
TechSummit is a (fictional, but representative) 2,500-attendee annual SaaS conference held over two days in Austin. The event mixes a main stage, four breakout tracks, a sponsor expo floor, and an evening party at the conference venue.
For the three years before adopting Fotowall, the brand marketing team had tried the standard playbook for driving social engagement: a published event hashtag (#TechSummit25), printed signage at every entrance, an emcee periodically reminding attendees to “tag your photos,” and a Twitter/X aggregator running on a screen in the lobby.
The numbers were always disappointing. Their internal tracking showed:
- Roughly 600-to-800 organic social posts per event using the hashtag (across 2,500 attendees)
- Most posts concentrated in a single Tuesday-morning keynote window
- Sponsor activations on the expo floor got almost zero hashtag love — attendees would visit a booth, take a photo, and never post it anywhere
Marcus Liang, the conference’s Head of Brand Marketing, summarized the gap: “We had a 2,500-person audience in a room together, and our visibility on social was less than what a single mid-sized B2B podcast gets in a week. Something was structurally wrong about how we were asking for engagement.”
The team identified two friction points:
- Hashtag friction. Attendees would take a photo, then have to decide whether they wanted to publicly post it to their followers. Most decided against it.
- No in-person feedback loop. Even attendees who did post got no visible reward — their photo lived on Twitter for ninety seconds before the next post buried it. The hashtag wall in the lobby was three months of stale 2024 content.
The approach
For TechSummit 2025, the team moved the entire engagement model to Fotowall on the Premier plan ($499/event with a 60-minute onboarding call + dry run).
The design decisions:
Three giant lobby screens running Fotowall in Mosaic mode. The main lobby had an existing 65” portrait screen rig that previously displayed the schedule. The team kept the schedule on a smaller monitor and dedicated the three large screens to a live photo mosaic, updating every five seconds as new uploads landed.
A QR code on every lanyard, every booth, and every breakout door. They printed the QR onto the back of the lanyard inserts — already in every attendee’s hand — so submitting required no thought and no app.
Auto-moderation with a human override. Fotowall’s auto-moderation handled the first 4,500 photos without intervention. A two-person brand team kept a moderation tab open and pulled three photos out over the two days — a faster, lighter review process than the old hashtag spam scan.
Sponsor logo rotation built into the wall. Each of the six platinum sponsors got 5-minute anchored slots through both days, rotating through the wall as a small banner. The rest of the time, sponsor booth photos uploaded by attendees would appear within seconds of being taken — sponsors got visibility from real activity, not from purchased screen time.
Optional Twitter cross-post. Attendees could check a box on upload that said “Also share to my Twitter/X with #TechSummit25” — a frictionless, opt-in version of the old hashtag campaign.
What happened
The lobby became, in the words of one sponsor’s CMO, “the most social part of the event we’ve ever had.”
Across the two days:
- 4,820 photos submitted by 1,340 unique attendees (54% of registered attendees)
- Median time from photo capture to wall display: 8 seconds
- Sponsor booth coverage went from negligible to 100+ minutes of cumulative on-screen time for each platinum sponsor — measured from photos featuring their booth or signage
- The opt-in Twitter cross-post sent 1,100+ photos to X with
#TechSummit25, almost double the previous year’s organic hashtag activity, and the hashtag trended regionally in Texas on Day 2 afternoon
The pre/post-event social mention tracking showed a 12% increase versus 2024 in conversation volume about the conference brand, measured for the four-week window around the event.
But the team’s qualitative read of the result was the bigger story.
“We’d been trying to drive attendees to the event hashtag for three years. The mosaic gave them a reason to participate in real time, in person. The hashtag took care of itself after that.”
— Marcus Liang, Head of Brand Marketing, TechSummit
Why the mosaic worked
Three reasons the team called out in their post-event debrief:
Visible reward. When you upload a photo, you can stand in the lobby and watch it appear on a giant screen within eight seconds. That immediate feedback is what hashtag walls — pulling from a delayed third-party aggregator — can never provide. The wall is the dopamine hit; social posting becomes a side effect.
Sponsors got real coverage from real moments. Instead of paying for a 5-minute logo loop on a screen no one was looking at, sponsors got 100+ minutes of unprompted attendee-captured booth content. Two sponsors specifically renewed their TechSummit 2026 spend citing the photo wall as a deciding factor.
The team spent zero hours hunting for spam. Auto-moderation handled the firehose. The team’s brand managers spent the two days at the event, not at a laptop.
The unexpected upside: sales prospecting
A second-order effect the team hadn’t planned for: their sales team used the Fotowall public gallery, which lived on for 90 days post-event, as a follow-up trigger. When an attendee opened the gallery (tracked anonymously via analytics), the team had a soft signal that the contact was still actively engaged with the brand. That fed into a re-engagement email cadence that the team credits with a 6% bump in qualified-pipeline contribution from the event.
Sidebar: the operational details
Setup time: 2 hours on Monday evening (the day before the event) — including dry-run with the venue AV team, three screens cabled and tested, and the moderation team trained.
Onboarding: A 60-minute call with the Fotowall team two weeks out, plus a dry-run check-in the day-of. Included in the Premier tier.
Network setup: Attendees uploaded over cellular and the venue Wi-Fi (both worked). The three lobby screens ran the wall URL in Chrome on dedicated mini-PCs hardwired to ethernet — the team’s standard practice for any live-stream display.
Moderation team: Two of the brand managers, working in shifts from their phones. Estimated total moderation time across two days: 90 minutes.
