§ III Process
How it works
Three steps to feedback with a stance, a rationale, and the exact passage to back it up.
- 01
Add your object
Eight object types, from a single social media post to an entire website — whatever carries your message, your Personas will review it.
- Website
- Ad
- Logo
- Social Media
- Product
- Proposal Check
- Ask the Room
- 02
Choose Personas + Criteria
Over 200 synthetic personas ready to use, filterable by Life-World and bias — new ones are added every week. Plus ready-made Criteria templates for every object type.
- 03
Review in ~20 minutes
Scores per criterion, verbatim comments from every Persona, an AI summary, a PDF report — and afterward, you go straight into a conversation with the Personas.
“Three superlatives, zero evidence. Anyone who wants to sell me something needs to argue with more rigor.”
Persona Chat
The Review is just the beginning.
Every Persona stays available after the Review — in character, with memory of what they said. Ask why a Score turned out the way it did, or what would have convinced them. An interview that takes minutes, not weeks.
Margarethe von Altenberg
CEO · Private Bank · Vienna
Why only 6.6 out of 10?
The site comes across as competent, but it still owes me proof. I see promises — no reference clients, no numbers. At my level, trust is delivered, not felt.
What would it take to convince you?
A named client with results, a methodology I can follow, a price without asterisks. Deliver that — and the 6.6 quickly becomes an 8.0.
What did you like?
The clear structure, and the absence of theatrics. I take that seriously. Now back it up with the same substance.

§ IV Limits
To be honest Synthetic personas complement real user research — they don't replace it (Nielsen Norman Group, 2024).
Who’s behind it
Radical Personas is a synthetic user research tool from Austria — built by two founders in Linz, with two decades of hands-on persona work behind them.
About us
§ V Comparison
A prompt isn’t research. A panel takes weeks. We sit in between.
| Comparison point | Generic LLM | Radical Personas | Traditional panel |
|---|---|---|---|
| Persona depth | Usually age, gender, job title | 8 psychological layers (Big Five · biases · Life-Worlds) | Real people, unfiltered |
| Reproducibility | Stochastic (prompt-dependent) | Reproducible, weighted Scores | Depends on the panel |
| Scientific basis | prompt-specific, corpus unknown | Stanford HAI · Kahneman · Schmitt et al. | Moderator and participant bias |
| Time to results | Response time: instant | ~20 min to PDF report | Avg. 42 days (Dscout) |
| Cost | Included in your LLM plan | from €4.17 per Review | €2,000–€15,000 per study |
| Stakeholder output | Chat log export | PDF report with Scores + AI summary | External report, usually extra |

§ VI Economics
A question of scale
Two orders of magnitude. In your favor.
Traditional
€2,000 to €15,000 per study, and 42 days on average until you see results.
Source: Dscout
Radical Personas
From €4.17 per Review. Free to try, no credit card required.
The math
A weak message usually surfaces after weeks in the market. With Radical Personas, it surfaces in 20 minutes.
The end result
The result is a PDF that holds up in meetings.
A scorecard for every criterion, verbatim comments from each Persona, and an AI summary — formatted for stakeholders, not dashboards.
§ VII Testimonials
What customers say
What our customers use it for.
Independent professionals and small teams from the German-speaking market (DACH) who use Radical Personas in their day-to-day work — from websites to ads to positioning. Quotes translated from German.
I run every new episode past several Personas. I see right away where the message loses people — and sharpen it before the episode goes live.
Daniel Friesenecker
Podcast Strategist & Coach · TheAngryTeddy
With Radical Personas, I test ads and posts on matching audiences before they run. That makes my recommendations defensible — I can show why something works.
Mario Hilger
Social Media Manager
I had my positioning reflected back to me by very different personalities. I would never have seen those blind spots on my own.
Petra Baumgarthuber
Leadership Coach & Consultant
Finally, feedback that comes with reasons — not just “like it” or “don’t like it.” Very valuable for growing my business.
Alfred Baumgarthuber
Owner · Licht-Konzept
Honest feedback from your target group is hard to come by. With Radical Personas, I have it in minutes — backed by real reasoning, not just a number.
Georg Gumpinger
Managing Director · Gut&Co Test & Consulting
The Personas read my website like a skeptical board: polite in tone, merciless on substance. Exactly the sparring you’d want from colleagues — and never get.
Thomas Moshammer
Mentor Coach for Executives
In the Persona test, the young trainee instructor and the mid-career switcher debate our course page at the same time — and they thoroughly disagree. Exactly the friction we need before the season starts, not once the course is underway.
Johann Reisenberger
COO · Snowsports Academy
My clients are at a turning point in their careers — one wrong phrase, and interest turns into hesitation. Luckily, the Personas hesitate out loud: they tell me which sentence they get stuck on, and why.
Andreas Weidinger
Career Coach & Trainer
