"Who wanted a call back Wednesday?"
Three weekend calls, two emails, one WhatsApp – and by Thursday no overview of who's first.
Your Wissenszwilling catches enquiries, drafts quotes, reminds your team and keeps your advertising in check. So you get back to working – instead of catching up every evening.

Sound familiar?
Enquiries, calls, emails, WhatsApp, time sheets, notes, reminders, ad reports. Three channels rain in every day – and you're the only person holding it all together.
Three weekend calls, two emails, one WhatsApp – and by Thursday no overview of who's first.
You sit in Word at night, copying old quotes, looking up rates, checking twice. The quote that should go out tomorrow goes out Friday.
Employees call: "How was the Müller job again?" When you're sick, everything stops.
€2,300 spent monthly. Calls come in. Which campaign was it really? How many were click fraud? You pay for guesses.
Field report on phone, delivery note photo, time sheet on paper. By the time it's invoiced, the month is over.
Three programs open, two logins forgotten, a CRM nobody uses. Everything still runs through WhatsApp and your head.
How your Wissenszwilling works
You don't need a new app no one opens. You need a control center where enquiries, calls, advertising and knowledge come together – so anyone on the team knows what to do in 5 seconds.
For your field team
Send a photo of the time sheet. Type "done." Accept a follow-up reminder. No app to learn. Telegram is already on most phones.
For you & the office
One web app. Today's callbacks, open quotes, due invoices, ad costs, knowledge base. All at a glance, sorted by impact.
In the background
Turns 2 sentences into a quote. Detects which campaigns bring real calls. Reminds you of overdue dunning. Answers from your data.
What you get
Each campaign gets its own number. Multi-ring on several staff. Calls recorded & transcribed. AI detects whether an on-site appointment was made.
For doctors, lawyers, sensitive practices. A Mac Studio in your office. Data never leaves the LAN. GDPR by architecture.
Callbacks, open quotes, due invoices, ad costs – sorted by impact. Your office staff sees the same status.
Every enquiry, every complaint, every routine email gets an automatic draft for your approval. Inbox in 15 min instead of 2 hours.
LinkedIn, Facebook, Instagram, YouTube, Google profile – on autopilot, always in your tone, always with approval workflow before posting.
Bot-suspicious IPs, dodgy geos, duplicate devices – server-side excluded. Ad budget stays with you.
