The Starting Point

Phone sales — but without a system.

A B2B sales team acquires business customers daily — by phone, structured, under time pressure. The problem: processes that cost time instead of closing deals.

Unstructured sales routine — Sketch

The Problem

  • Call scripts stored in Word documents
  • Leads managed in Excel spreadsheets
  • Manual data entry after every call
  • No overview of team performance
  • Lost leads, inconsistent conversations
Clean system — tidy workspace

The Goal

  • One system instead of three tools
  • AI coaching directly during the call
  • Automatic lead capture
  • Measurable results per agent
  • No data with third-party providers
The Brief

Three requirements. One system.

No third-party CRM, no monthly license fees, no data with third parties — and yet everything a modern B2B sales team needs.

Call Management

Structured, repeatable, immediately usable for every agent — with AI coaching in real time that responds to the current conversation situation.

Lead Management

Centralised, team-capable, with complete call history and automatic lead scoring — no more manual transfers.

Team Analysis

Who performs how, which arguments work, where is the potential — measurable, at a glance, exportable as PDF.

The Tool in Action

This is what it looks like — live in the browser.

The AI conversation assistant runs directly in the web browser — no download, no setup. Agents open the tool, select the conversation type and are guided step by step through the call.

FAQ

Questions & Answers.

What is AI sales automation?
AI sales automation connects traditional sales processes with artificial intelligence. Instead of Excel spreadsheets and Word scripts, your team works with a web-based tool that structures conversations, captures leads automatically, and delivers real-time AI coaching — all on your own server.
What does a custom B2B sales tool cost?
Development is a one-time project with no ongoing licence fees. The exact price depends on your requirements — typical projects range from €3,000 to €10,000. Compared to monthly SaaS subscriptions, the investment pays for itself quickly.
What is the difference from HubSpot or Salesforce?
Standard CRMs like HubSpot or Salesforce offer generic features — often too much, often the wrong things, always with monthly costs. Our approach: a tool that maps exactly your processes, runs on your own server, and transfers no data to third parties. No licence fees, no cloud dependency.
How long does development take?
A first functional system is typically ready within 4–8 weeks. The exact timeline depends on the scope and complexity of your requirements. We develop iteratively — you see first results early in the process.
Is the tool GDPR-compliant?
Yes. All data — conversation history, leads, user activity — resides on your own web server. No cloud subscription, no data transfer to third parties. The only external connection is the AI API (Anthropic), which analyses conversations but does not store any customer data.
Who is a custom AI sales tool suited for?
Primarily for B2B sales teams that acquire customers by phone every day and currently work with Excel, Word, or multiple disconnected tools. Ideal from 3–5 agents — that is when the investment pays off fastest.
