AI masterclass: detailed persona creation avoids cost traps

Written by Lars-Thorsten Sudmann | Feb 28, 2026 12:58:22 PM

1️⃣ Getting started: The real problem

You want to sell AI solutions, further training or digital services - and say:

"Our target group is tradespeople."

That sounds clear. But it's not.

Because:

  • A 28-year-old master roofer ticks differently than a 58-year-old HVAC contractor.
  • A self-employed electrician has different concerns than an employed foreman.
  • A 50+ craftsman thinks differently about AI than a digital native.

Without a precise persona:

  • your marketing messages become interchangeable
  • your offers do not hit the mark
  • your conversion remains low

And this is where AI comes into play.

2️⃣ Why the problem remains

Typical mistakes when creating personas:

❌ Gut feeling instead of data
"I know my customers."

❌ Personas that are too superficial
Age, profession, income - that's it.

❌ No psychological triggers
What keeps this target group awake at night?
What scares them?
What really motivates them?

❌ No systematic use of AI

Many only use ChatGPT or Gemini for:

"Create a persona for tradespeople over 50."

The result: generic, interchangeable, of little strategic use.

The quality does not depend on the tool - but on the process.

3️⃣ The concrete solution: the 4-step persona model with AI

If you want to use AI properly, you need structure.

🔎 The 4-stage persona model

  1. Demographic basis
  2. Entrepreneurial reality
  3. Psychological level
  4. Digital & AI maturity level

Now I'll show you how to implement this with Google Gemini and ChatGPT - including a process comparison.

Step 1: Create a persona with Google Gemini

🛠 Procedure with Gemini

Prompt 1 (basic):

Create a detailed persona profile for the 
target group "Craftsmen 50+" in Germany.
Focus: Self-employed or owner of a small business.
Please structure into: Demographics, professional situation,
challenges, goals, attitude towards digitalization,
typical statements.

 

📌 Observation

Gemini delivers:

  • structured answers
  • solid demographic estimates
  • relatively conservative assumptions
  • less psychological depth

The content seems:

  • factual
  • slightly statistical
  • less emotional

🔄 Prompt 2 (deepening)

Now it gets exciting.

Go deeper into the fears, inner resistance and typical 
mindsets of this target group. What unconscious
concerns about AI and digitalization?

 

This shows:

  • Gemini remains rather rationally
  • formulates with restraint
  • avoids strong emotional escalation

Step 2: Create a persona with ChatGPT

Now the same procedure with ChatGPT.

🛠 Prompt 1 (basic)

Create a detailed persona profile for 
"Craftsman 50+", self-employed, small business in
Germany.
Please be very practical and realistic.

 

📌 Observation

ChatGPT:

  • formulates more vividly
  • thinks more in everyday situations
  • incorporates typical statements
  • provides more concrete examples

🔄 Prompt 2 (psychological depth)

What unspoken fears, resistance and typical 
typical thinking errors does this persona have towards AI?

This shows that ChatGPT delivers

  • stronger psychological patterns
  • typical self-talk
  • realistic statements such as
    "That's only for big corporations."
    "I'm too old for that."

The answers are

  • more strategically useful for marketing
  • clearer in the argumentation

📊 Comparison: Gemini vs ChatGPT

Criterion Google Gemini ChatGPT
Structure Very neat Also structured
Emotionality Restrained Higher
Psychological depth Medium High
Marketing usability Good Very good
Storytelling Weaker Stronger


Important:
The tool does not determine quality.
The prompt process decides.

4️⃣ Practical example: AI training for tradespeople 50+

A medium-sized provider of AI training wanted to address skilled trades businesses.

Before

  • General AI advertising
  • Focus on efficiency
  • Technical language
  • Hardly any response

AI-supported persona analysis

The following key points were identified with ChatGPT:

Main concerns:

  • Skills shortage
  • bureaucracy
  • Succession
  • Time pressure

Internal resistance to AI:

  • Fear of loss of control
  • "I don't understand the technology"
  • "My employees won't go along with it"

Afterwards

Communication was adapted:

Instead of:

"AI increases your process efficiency by 30%."

Now:

"Less paperwork. More time on site.
AI as a digital master in the background."

Conversion rate: significantly increased.

5️⃣ Steps that can be implemented immediately

If you want to apply this yourself:

Step 1

Define your persona very clearly:

  • Age
  • role
  • Company size
  • Region

Step 2

Use both tools one after the other:

  • Gemini for factual structure
  • ChatGPT for psychological depth

Step 3

Ask in-depth questions:

  • "What is he thinking but not saying?"
  • "Which arguments really convince him?"
  • "Which terms repel him?"

Step 4

Create from this:

  • Messaging guidelines
  • Handling objections
  • Offer positioning

6️⃣ Strategic positioning

If you don't develop personas deeply enough

  • you burn marketing budget
  • you produce irrelevant content
  • you remain interchangeable

Especially with target groups like "craftsmen 50+":

They buy:

  • Trust
  • security
  • Relief

Not:

  • Technology
  • Buzzwords
  • Visions of the future

Those who understand this gain market share.
