Marketing without customer voice is guessing
Most B2B marketing teams operate on second-hand customer language. The headline came from a brainstorm. The persona deck came from a sales call from 18 months ago. Testimonials came from the three customers who said yes to a Zoom. The result is messaging that feels right inside the room and lands flat outside it, because it's not actually how customers describe the problem.
Diaform closes that loop. Run AI-led conversations across your buyer pool to test concepts before launch, sharpen positioning with real switching stories, and collect testimonials at scale. Each transcript comes back with sentiment, themes, and pull-quotes you can paste into a landing page or a deck the same day.
Where marketing research breaks
You can't validate a concept pre-launch
The choice is usually: ship the campaign and hope, or pay an agency $40k for a message test that lands six weeks late.
Persona research is stale
The personas in your deck were built from sales calls that happened during a different macro environment. Real buyers describe themselves differently now.
What marketing teams get from Diaform
Concept testing in a week
Show two messaging concepts and ask for unaided reaction. The AI probes on what landed, what confused, and what the buyer would tell a colleague.
Testimonial extraction at scale
Send the link to happy customers post-launch or post-renewal. The AI surfaces quotable moments and asks permission to use them.
Switching stories on tap
Run competitive switching interviews with new customers. Build the 'why we switched' content your sales team wishes existed.
Persona refresh, quarterly
Run the same study every quarter. Watch how buyer language, jobs, and triggers evolve, and update your messaging before it goes stale.
30+ languages
Test global messaging in the buyer's native language. The AI runs locally and summarizes in English for the team.
Per-campaign knowledge base
Upload the concept, the brief, the competitor positioning. The AI uses that context to ask sharper, more relevant follow-ups.

Frequently asked questions
Q
Can I actually use the quotes? What about consent?
Yes. The AI can be configured to ask for explicit testimonial permission inside the conversation, capture name and title, and confirm what's quotable. Everything is logged with timestamps for compliance.
Q
How does this compare to a research agency?
An agency charges $20-50k and takes 4-8 weeks for a message test. Diaform runs the same study for $89/month, with answers in days. You give up some hand-curated insight, but you can run the study three times in the time an agency runs it once.
Q
Will customers respond if it's not from a human?
Voice + adaptive probing makes the experience feel closer to an interview than a survey. Completion rates beat static surveys, and answer depth is typically 2-3× longer because the AI follows up.
Q
Can I run a study in multiple languages?
Yes, 30+ languages. The same link adapts to the respondent's language. You get summaries in English plus original-language transcripts.
Q
Can it pull out themes across the whole study?
Yes. Cross-conversation theme clustering and sentiment surface the patterns. Top quotes per theme are flagged so you can paste straight into a deck or landing page.
Q
Does it work for B2C as well as B2B?
Yes, though it's most popular with B2B SaaS marketing teams who need depth on a small buyer pool. For high-volume B2C work, the same model applies.
