100 Million Samples: What We Have Learned in 20 Years

100'247'832. That is how many samples PROMOKANT has distributed since 2006. Every single one by hand, by a real person, to a real human. No clicks, no impressions. Handshakes. In this article, I share what we have learned in 20 years. Not the marketing version. The honest one.

Lesson 1: location beats everything

We have run samplings at more than 500 different locations in Switzerland. Train stations, shopping centres, festivals, corporate sites, neighbourhood streets. And after 20 years, I can say one thing with certainty: location decides success or failure. Not the briefing. Not the budget. The location.

A concrete example. In 2019, we tested two identical sampling setups for a beverage brand. Same product, same team, same time of day. Location A: Bern train station, main hall. Location B: Westside shopping centre, entrance area. The result: Bern station delivered 2'800 contacts per day. Westside delivered 1'100. Same effort, 2.5x more output.

Why? Frequency and mindset. At the station, people are on the move. They have 3 minutes of waiting time. They are open to new things. At the shopping centre, they are focused on their shopping. They do not want anything extra.

Our top 5 locations by average contacts per day and team:

Location	Contacts/day	Acceptance rate
Zurich HB, main hall	3'200	72 %
Bern station, Welle 7	2'800	68 %
Basel SBB, Passerelle	2'500	65 %
Lausanne Gare, Hall	2'100	61 %
Lucerne station	1'900	63 %

We have been collecting this data over years and stored it in our kyoX platform. Every new client benefits from it. That is an advantage no newcomer can offer.

Lesson 2: your team is your product

Here is the uncomfortable truth: most sampling campaigns do not fail because of the concept. They fail because of the staff. An unmotivated promoter does not just cost you contacts. They damage your brand.

In 20 years, we have deployed more than 12'000 promoters. Around 800 of them are still in our active pool today. That is a retention rate of under 7 %. Sounds harsh? It is. But those 800 people make the difference.

We learned early on that casting matters more than training. You can teach someone how to present a product. You cannot teach someone how to approach people. That is personality.

Our solution: we built our own rating system. After every assignment, team leaders rate promoters on five criteria. Anyone who falls below 3.5 out of 5 gets no further assignments. Anyone above 4.5 is booked with priority. Over years, this builds a pool that truly delivers.

The effect is measurable. Teams with top-rated promoters generate on average 40 % more contacts than teams with newcomers. For product sampling campaigns, that is the difference between CHF 2.80 and CHF 4.50 per contact.

My advice to every Brand Manager: ask your agency about promoter retention. If the answer is "we recruit per project", you know the score. An in-house pool is not optional. It is the foundation.

Lesson 3: data changes everything

In 2006, our reporting looked like this: promoter fills out a paper form at the end of the day. Team leader types the numbers into Excel. Three weeks after the campaign ends, the client gets a PowerPoint. That was standard. Everyone worked that way.

Today, our real-time reporting with kyoX delivers the numbers live. Contacts per hour, location performance, photo documentation, GPS tracking. The Brand Manager sees on their laptop what is happening at Bern station. While it is happening.

This has changed three things:

1. Campaign optimisation in real time. When location A delivers only 50 % of expected contacts after two hours, we shift resources to location B. Before, we noticed it only after the campaign. Too late.

2. Trust. Brand Managers used to have to take our word on the numbers. Today they see them for themselves. That has completely transformed the client relationship. Less control, more partnership.

3. Benchmarks. Over 200 projects per year generate data. A lot of data. Today we know that a beverage sampling at Zurich HB in July will deliver between 2'800 and 3'400 contacts per day. We know that the acceptance rate for snack products is 15 % higher than for non-food. These benchmarks help us write realistic quotes.

The investment in technology was expensive. Developing kyoX cost us a seven-figure amount. But it is the reason we today serve more than 50 FMCG brands.

Lesson 4: not every channel fits every product

Field marketing is not just field marketing. There are fundamental differences between channels. And after 100 million samples I know: most briefings pick the wrong channel.

Channel	Strength	Best for	Cost/contact
Station/event sampling	High frequency	FMCG awareness	CHF 1.80 – 3.50
POS promotion	Direct conversion	New products in retail	CHF 4.00 – 7.00
Roadshow	Brand experience	Premium brands, launches	CHF 8.00 – 15.00
Merchandising	Shelf optimisation	Ongoing distribution	CHF 25 – 40/POS

The most common misjudgement: Brand Managers want roadshows even though their goal is reach. A roadshow with its own truck, interactive station, and three promoters typically reaches 400 to 600 contacts per day. The price per contact is therefore significantly higher than for classic reach formats.

A product sampling at the same location typically delivers 2'000 to 3'000 contacts per day. If your goal is trial, the maths is clear: sampling beats roadshow on Cost per Contact by a wide margin.

Roadshows pay off when you have a story to tell. When your product needs explanation. When you need photos for social media. When it is a product launch event. But not for pure trial driving.

Our approach today: we recommend channel mix over single channel. A typical campaign combines two days of station sampling for reach with one week of POS promotion for conversion. Data from the sampling feeds directly into POS planning. That closes the loop.

Lesson 5: the most expensive mistakes

20 years also means 20 years of mistakes. Here are the five that cost us the most:

Mistake 1: overpromising. In the early years, we put numbers in quotes that we could not deliver. "10'000 contacts in two days" sounds good in the pitch. But if the weather does not cooperate or the location underperforms, you end up at 6'000. Today we work with ranges and guarantee minimum values.

Mistake 2: no backup staff. Sounds simple. But the number of campaigns we ran in the early years with too few staff because someone got sick is embarrassing. Today we always plan 15 % overcapacity. Better one promoter too many than one too few.

Mistake 3: underestimating logistics. A sampling can be planned to perfection. If the goods are not at the location on time, all that planning is worthless. Once we had 50'000 samples stuck in customs. Since then, we have our own warehouse and organise shipping internally.

Mistake 4: late debriefing. We used to debrief two weeks after the campaign. By then the team was on the next project. The details get lost. Today the team leader debriefs the same day, directly via kyoX.

Mistake 5: saying yes to the wrong client. Not every client is a fit. We have learned that projects with unrealistic expectations, too low a budget, or no respect for our team cost more than they bring in. Since 2018, we have deliberately said no to projects that do not fit. It was one of the best decisions.

What is coming: field marketing 2030

Three trends that will shape the next decade:

Data-driven planning becomes the standard. Gut feeling is no longer enough. Agencies without historical data will disappear. Clients expect forecasts based on benchmarks, not estimates based on "experience".

Sustainability becomes a deal breaker. Plastic giveaways, unnecessary print materials, diesel generators for events. That was yesterday. We already see tenders today that include sustainability criteria. In five years, it will be the standard.

Integration of online and offline. The sampling of the future links directly to the online shop. The QR code on the sample leads to a personalised landing page. Data from the field contact flows into the CRM. Anyone who looks at field marketing in isolation will lose.

PROMOKANT has been around since 2006. We are planning the next 20 years. With better data, better staff, and better technology. But the foundation stays the same: one person hands another person a product. That is field marketing. And it works.
