Agents, meatballs, and the SF desk.
Five chalk stencils on the SoMa sidewalks that the Relevance AI customer already walks. Each stencil carries the same payload: "Relevance AI · Agents & Meatballs · 945 Market St · Oct 15 · 2–6PM · @relevance_ai." A specific event, a specific address, a specific window. The pedestrian who reads the stencil on a Tuesday morning coffee run knows exactly where to be on October 15, and the location is two blocks from where they're already walking.
The "Agents & Meatballs" event was a community activation: afternoon-into-evening, demos, conversation, food, in-person product trial. The brief was tight. Drive AI-builder foot traffic to 945 Market Street on October 15, 2pm to 6pm, without leaning on the same paid-social channels every AI startup is already saturating.
Sidewalk stencils solved a specific geometry. Relevance AI's local customer concentration is dense in SoMa, in the corridor between Market and Mission, 2nd through 6th Streets, where the engineering teams of every AI-tooling startup actually work. A stencil on the pavement reads at exactly the right altitude. The developer looking down at their phone, the founder walking between coffee meetings, the engineer heading to lunch. Visibility at pedestrian eye-line, in a neighborhood where the audience already walks, advertising an event two blocks away.
Where we ran it.
The 5 placements:
- Outside 945 Market St. The event venue itself, with foot-traffic immediately adjacent to the door. - Market Street + 3rd corridor. The morning commute artery for the SoMa engineering audience. - Mission Street between 4th and 5th. Secondary corridor, evening foot traffic feeds into the event window. - 2nd Street near Howard. Anchor placement for the south-SoMa engineering offices (Salesforce Tower adjacency). - Howard between 4th and 5th. High-density mixed-use corridor with afternoon foot traffic peak.
Each placement was selected for line-of-sight to the event venue or for capture of the natural foot-traffic flow toward Market Street. The pedestrian who reads the stencil on Monday morning knows where 945 Market is by Tuesday. The address compounds in recognition through repeat encounter.
What we ran.
Single-color (white chalk-mix) stencils, 30 × 30 in nominal square format. Stencil mask cut from durable 0.060-in PVC for repeated use across placements. The creative is dense by design: brand mark, event name, address, date, time, social handle. Five pieces of information in a single read. Stencil typography is condensed and high-contrast specifically to make that density legible from 6 feet away.
Chalk-mix selection over acrylic paint was deliberate. San Francisco's sidewalk-stencil case law treats chalk formulations as non-defacement, removing legal risk for the venue partner at 945 Market. Property-owner consent was secured for all five placements before install, and the consent letters specify the chalk formulation by name. By two weeks post-event, all five stencils had washed off under normal SF precipitation.
Install ran across a 4-day pre-event window.
Day 1: venue-adjacent placement at 945 Market and the Market Street + 3rd corridor anchor. Days 2 to 3: the three secondary corridors (Mission, 2nd Street, Howard). Day 4: photo verification and crew handoff to event-day operations.
Install timing favored early morning (6am to 8am) to minimize pedestrian disruption and to allow chalk to fully cure before the morning commute peak. Each stencil took 8 to 11 minutes start-to-finish: surface prep, mask placement, chalk-spray application through the stencil, mask removal, photo capture. The crew worked two operators in parallel for the Market Street corridor where placements concentrated.
The 4-day window meant pedestrians had the full Tuesday-through-Friday commute cycle to encounter the stencils before the Saturday event. Event-week foot traffic into 945 Market Street showed measurable lift in the lead-up days. Relevance AI's venue team reported pre-event traffic asking about the event well above their forecast.
Proof.
The client received a placement manifest with route map the same day.
Event-day foot traffic: 945 Market Street saw walk-in attendance above Relevance AI's forecast. The brand's team specifically credited the sidewalk stencil work with a meaningful share of the in-person turnout, particularly the audience that didn't engage with the event's paid-social channels but did walk past the stencils on their daily commute.
Post-event durability: chalk washed off naturally within 18 days of install, leaving no residue on any of the five surfaces. Property owners reported zero pushback. The legal-and-cleanup angle worked exactly as the brief required.
Notes.
The audience is hyperlocal (you can walk to 945 Market from where they work), the message is dense (date, time, and address all in one read), and the medium feels native to the neighborhood (SoMa expects street art and doesn't expect bus-shelter ads). Paid social for the same event would cost 3 to 5x more per qualified attendee and would compete in a saturated channel.
The campaign also confirmed a tactical principle: place the highest-density stencil directly adjacent to the venue itself. The 945-Market-adjacent placement worked as a navigational beacon for everyone who'd encountered the brand through any channel and was trying to find the actual door on event day. One stencil within line-of-sight of the venue does more wayfinding work than three Instagram story posts.
The misfile correction in the campaign archive (four stencil photos that had been mis-tagged as Relevance AI but were actually FIFA Toronto installs) became its own quality-control lesson for the photo pipeline. Per-campaign GPS verification now runs at intake before any photo joins a campaign archive. The corrected campaign is exactly five stencils, exactly as deployed.
Five stencils, four days, one event door. The SF afternoon went as briefed.
