This campaign is the canonical example in our Street Team Activation Playbook for the Touches-per-Hour staffing math and the SPINS measurement framework. Read the full playbook for the complete demo-program formula.
The Challenge
A Top-25 CPG snack brand was launching a new flavor extension in Q1 — a higher-protein, lower-sugar variant of their hero SKU positioned to capture incremental shelf space in the better-for-you category. The new flavor had won placement at 600 Whole Foods Market and Sprouts Farmers Market locations across 5 priority markets (Los Angeles, Denver, Austin, Chicago, Boston). Placement was secured. The hard part was now velocity — convincing the buyer at each banner that the new SKU could earn its facings by moving enough units in the first 90 days to clear the velocity threshold for permanent placement.
The category management team set a clear bar: the new SKU needed to hit at least a 12% velocity lift versus the brand's hero SKU baseline in the same stores during the first four weeks, with SPINS-verified scanner data as the system of record. Anything below 12% put the SKU at risk of being delisted at the spring reset. Anything above 15% would justify expanding the program to a second tier of 1,200 stores in the back half of the year. The brand's CMO put the demo budget at $35K — a deliberately small bet that had to prove ROI before more budget would unlock.
- SPINS scanner data was the contractual measurement standard. Every store in the program had a four-week pre-baseline and a four-week measurement window. The 18% target had to be isolated against a control set of 120 non-demo stores in the same banners.
- Whole Foods and Sprouts each had distinct demo protocols, COI requirements, and ambassador appearance standards. The brand needed an agency that already had vendor onboarding completed with both banners and could deploy without slowing the timeline.
- Every brand ambassador needed an active food handler certification (state-specific) and had to comply with each banner's sampling station setup standards — including approved sample sizes, allergen labeling, and gloves/hairnet protocol.
- The brand's category insights team needed daily reporting on samples distributed, trial-to-purchase conversion at the demo station, and consumer feedback themes — so they could adjust on-pack messaging for the next print run.
- Five markets meant 5 different state food-handler regulations, 5 different ambassador labor markets, and 5 different distribution warehouses for sample replenishment. The campaign's logistics required tight regional coordination.
The Solution
Street Teams Co designed a 5-week, 5-market in-store demo program structured around the Touches-per-Hour staffing math and a SPINS-integrated measurement framework. The deployment used 6 brand ambassadors per market, working 5 days per week for 8 hours per shift, rotating across the highest-traffic stores in each market. The campaign covered 600 stores total, with the top 240 stores receiving multiple demo days.
In-store CPG demo staffing is governed by one formula: Touches per Hour × Trial Rate × Conversion Rate × Shift Hours × Ambassadors = Total Trials. The Street Team Activation Playbook details how to size each variable for your category — for premium snacks, 50 TPH at 78% trial and 35% trial-to-purchase is the proven benchmark.
- 6 ambassadors per market — all with active state-specific food handler certifications, all vetted against Whole Foods and Sprouts vendor compliance lists, and all trained in person on the brand's product story, demo flow, and consumer feedback capture protocol.
- Store tiering for measurement integrity. 240 Tier 1 stores (the highest-traffic locations in each banner per market) received 2-3 demo days during the 5-week window. 360 Tier 2 stores received 1 demo day. A control set of 120 stores received zero demo activity and served as the SPINS baseline against which incremental lift was measured.
- SPINS integration. The brand's category insights team and Street Teams Co's analytics lead ran a joint weekly review of SPINS scanner data — per-store weekly velocity for the new SKU, controlled against the same-banner control stores. The 18% velocity lift was confirmed at week 4 and held through the post-demo trailing period.
- Demo station kit. Each market received standardized demo station kits — branded tablecloth, sample cups (1 oz for compliance), allergen signage, consumer feedback iPads, and pre-portioned sample stock for 5 days of activation. Replenishment shipments arrived every Wednesday from the brand's regional 3PL.
- Real-time reporting. Every ambassador logged samples distributed, trial-to-purchase conversion (tracked via observable purchase at the register within 5 minutes of demo interaction), and 3 short consumer-feedback themes per shift. The brand's category team had a 7 AM ET daily report and a weekly SPINS reconciliation deck.
The Staffing Math
Here is the Touches-per-Hour formula applied to this campaign. The brand's previous demo agency had under-staffed by 30% because they sized the program off of total samples rather than off of Touches per Hour. The Street Teams Co staffing model started from the math and worked backwards:
- Target Touches per Hour: 50 (a conservative benchmark for a premium snack demo in a high-traffic grocery banner).
- Trial Rate: 78% (the percentage of touches that resulted in the consumer accepting a sample and tasting).
- Sample yield per shift: 50 TPH × 78% × 8 hours = 312 samples per ambassador per shift.
- Trial-to-Purchase Rate: 35% (verified by observed purchase at the register within 5 minutes of the demo interaction — the brand's category team validated against POS data weekly).
- Per-shift purchases: 312 samples × 35% = ~109 incremental units sold per ambassador per shift.
- Campaign math: 30 ambassadors (6 per market × 5 markets) × 5 days/week × 5 weeks × 312 samples = ~234,000 sample opportunities, of which 58,000 actually distributed in the field (the gap reflects shift utilization, weather, and store traffic variance).
- Incremental units sold: 58,000 samples × 35% trial-to-purchase = ~20,300 incremental units sold at the demo register. Add the lift on subsequent same-week purchases by trialed shoppers and total incremental units climbs to roughly 41,000.
The Results
The 5-week, 5-market demo program delivered every contractual KPI and significantly exceeded the velocity threshold needed to lock in permanent shelf space. The 18% SKU velocity lift, SPINS-verified against the 120-store control set, cleared the 15% bar for expansion to the second tier of 1,200 stores in Q3. The $1.2M in incremental retail sales translated to a 34x return on the $35K demo budget — a ratio that recalibrated the brand's view of in-store demo as a measurable, scalable channel rather than a discretionary trade-marketing line item.
The category insights team also pulled three high-signal consumer feedback themes from the ambassador-logged shift notes: 67% of trial-conversion shoppers cited "better protein than I expected" as the primary purchase driver, 31% specifically mentioned the lower sugar content, and 18% asked about the brand's broader product line, suggesting cross-SKU pull-through opportunity. The brand updated its on-pack callouts for the next print run based on these themes and saw an additional 4-point lift in trial-to-purchase in stores receiving the updated packaging six weeks later.
How It Worked: The Methodology
Four operational moves made the difference between an average demo program and a 34x ROAS campaign:
- Staffing was sized from the math, not from the budget. The brand's previous demo agency had walked in with a fixed budget and worked backwards into ambassador headcount. Street Teams Co started with the velocity-lift target, reverse-engineered the trial volume required, applied the Touches-per-Hour formula, and arrived at the 30-ambassador deployment.
- SPINS measurement was integrated from day one. The 120-store control set was selected before the demo schedule was published. The control stores were never exposed to demo activity, which preserved the integrity of the velocity-lift comparison.
- Consumer feedback was systematized at the ambassador level. Every ambassador logged 3 high-signal feedback themes per shift in a structured form. The category insights team had 600+ data points per week instead of an end-of-campaign focus group summary.
- Banner compliance was zero-incident. All 30 ambassadors had active food handler certifications. Every store visit passed banner audit on first inspection. Zero compliance incidents across 1,200 demo days kept the brand's vendor scorecard in green status with both banners.

Frequently Asked Questions
How does SPINS measurement work for in-store demo campaigns?
SPINS provides scanner data from natural and specialty retailers including Whole Foods, Sprouts, and other premium grocery banners. For demo campaigns, we baseline a SKU's weekly velocity in the four weeks prior to the demo, then measure velocity during and four weeks after. The difference, controlled against non-demo stores in the same market, isolates the incremental velocity lift attributable to the in-store demo activity.
What is a realistic Touches per Hour rate for an in-store CPG demo?
In-store demo Touches per Hour vary by store traffic and product category but typically range from 35-65 shoppers per hour for a well-placed demo station in a high-traffic grocery banner. Trial conversion (sample → tasted) sits at 70-85% for snack and beverage categories, and trial-to-purchase typically lands at 25-40% depending on price point, sample quality, and the ambassador's product knowledge.
How quickly can Street Teams Co staff 600 stores across 5 markets?
Street Teams Co can staff a 600-store, 5-market demo program in 21-28 days from contract signature for an established CPG launch. The first two weeks cover ambassador recruiting and food-handler certification verification, retailer paperwork (COIs, vendor onboarding), and demo kit assembly. Weeks 3-4 are execution. Larger programs (1,000+ stores) typically need 30-45 days of lead time.
