We connect to the tools you already use (email, CRM, telephony, shop, calendars).

Our 4 Offerings

How we helped other succeed

Real-Estate Concierge Chatbot (Voiceflow + DB)

Problem:

Inquiries arrive after hours; agents repeat the same answers; booking a viewing takes too many messages.

Solution:

A concierge that qualifies buyers, shows a carousel of matching listings, and proposes bookable timeslots — all in one flow.

How We Did It:

Voiceflow UI with buttons/cards; search + booking through your database; optional calendar sync; GDPR-friendly setup.

Benefit:

More qualified viewings, faster replies, and clean handoff to sales.

Voicemail Transcriber

Problem:

Mitarbeiter verlieren viel Zeit damit, Voicemails anzuhören, Nummern abzuschreiben und Zusammenfassungen zu erstellen.

Lösung:

Neue Voicemails werden automatisch zu strukturierten E-Mails mit Anruferdaten, vollständigem Transkript und einer handlungsorientierten Kurz-Zusammenfassung.

Umsetzung:

n8n reagiert auf Starface-E-Mails, Whisper transkribiert die Audiodatei, GPT-5 erstellt Zusammenfassung und Extraktion, das Ergebnis wird als klare HTML-E-Mail versendet.

Vorteil:

Von 5-10 Minuten runter auf 1–2 Minuten Gesamtverarbeitung pro Nachricht, keine verpassten Anrufe und deutlich schnellere Rückrufe.

Spare-Parts Email Handler (Shopware)

Problem:

4–5k yearly parts emails overload teams; links and SKUs are pasted by hand; upsells are lost.

Solution:

Semi-automated drafts with direct product links, alternatives, and bundles — approved by staff in seconds.

How We Did It:

n8n/Zapier + Shopware API for product search; prompt tuning on past emails; batch approvals and SLA alerts.

Benefit:

70–85% workload reduction and higher shop conversions.

Multilingual Voice Appointment Agent

Problem:

Repetitive scheduling calls and language barriers slow reception and support.

Solution:

A voice agent that answers, qualifies, and books times across languages — then confirms by SMS/email.

How We Did It:

Telephony + LLM + calendar integration; guardrails for safe, concise handling; analytics on calls and bookings.

Benefit:

Fewer missed calls, faster bookings, happier customers.
