We build your CRM and integrate it with your information system and tools.

Your CRM can talk to your entire digital environment.

We can connect your CRM to:

Your CRM

[ Built-in AI ]

We add intelligence to your CRM.

AI can be built in wherever it delivers real value.

For example:

  • Business card scanning

    A card photographed at a trade show becomes a lead record.

  • Email processing

    Incoming emails read, summarised and attached to the right opportunity.

  • Customer request triage

    Customer service requests sorted by topic and urgency.

  • Meeting preparation

    The customer's history and open quotes summed up in a few lines.

  • Visit reports

    Notes dictated on the road, written up in the customer record.

  • Sales assistant

    An assistant that answers your sales reps from your offers and price lists.

  • Plain-language search

    Customers with no orders in the past year, listed with a single question.

  • At-risk deal detection

    An opportunity losing momentum, flagged from its latest exchanges.

  • Record deduplication

    A company entered twice, spotted even under a different spelling.

AI becomes a feature of your CRM, not a standalone tool.

Have an AI use case that isn't listed here?

These use cases are only examples.

We build AI in wherever it saves your teams time: call transcription, email drafting, cross-selling suggestions, lost-deal analysis, etc.
