Klarruf Principles & Architecture

Clear conversations.

Sales conversations shape every deal, customer trust, and company revenue. The hard questions around call recording, GDPR consent, and AI intelligence deserve thoughtful, transparent answers. Here is our work and architecture so far.

01Audio Engine & Dialects

Precision speech recognition tailored for European B2B conversations.

Standard speech-to-text models stumble over technical German enterprise acronyms and the vocabulary a single company uses every day. Klarruf transcribes German and English business calls, primed with your own company vocabulary — and without a bot listener sitting in the call.

✓
German and English transcription, with a per-workspace vocabulary for names and acronyms the model would otherwise mangle
✓
Calendar sync matches an uploaded recording to the meeting it belongs to — Klarruf never joins or records a call itself
✓
Speaker separation into rep and customer, with every turn editable when the model gets one wrong

02GDPR & Legal Compliance

Built in Frankfurt. Governed by §201 StGB & Zero Model Training.

✓
ISO-27001 certified AWS Frankfurt infrastructure with end-to-end encryption (AES-256)
✓
Zero AI Model Training guarantee: your customer calls never improve public LLMs
✓
Configurable data retention schedules (auto-purge after 30, 60, or 90 days)

03Rep Enablement & Coaching

Turning a 45-minute call into a structured follow-up while you make coffee.

Reps spend hours every week typing call notes and drafting follow-up emails from memory. Klarruf surfaces the customer objections, the agreed actions and the next step, then drafts the follow-up email in German or English.

✓
Objection mapping by category (pricing, timing, competitor, integration, authority, compliance)
✓
Action items and the single agreed next step, each quoted back to the moment it was said
✓
1-click follow-up email draft, written from the analysis rather than from memory

04CRM Automation

Clean pipeline data directly in HubSpot and Salesforce.

Sales managers often hear about a stalled deal weeks after the call that stalled it. Klarruf writes the call summary, the agreed next step and any competitor mention onto the deal itself, so the pipeline reads correctly without anyone opening a second tab.

✓
1-click sync of the call note to a HubSpot deal or a Salesforce opportunity
✓
Klarruf writes the note and reads your deals to attach it to the right one — it never changes a deal stage on your behalf
✓
Pipeline visibility without micromanaging rep notes

05Works Council & Fair Play

Built with German Works Councils (Betriebsräte), not against them.

Employee monitoring tools destroy sales team trust. Klarruf was intentionally architected to empower reps rather than surveil them. Built to avoid prohibited workplace emotion recognition and support compliance-focused conversation analysis.

✓
No emotion or sentiment analysis anywhere in the product — deliberately omitted under EU AI Act Article 5(1)(f)
✓
Calls are scored, people are not: the quality score rates the conversation, and no report ranks one rep against another
✓
Reps decide what gets uploaded — Klarruf has no bot that joins meetings and records on its own
✓
Configurable retention, one-click workspace export, and deletion on request
