Fewer cases. More depth.

We take on a small number of projects per year. What's public here are cases we're cleared to share. NDA projects are shown privately on a call.

    Internal content platform with an AI assistant for sales & ops teams.

    Field teams were losing time hunting for documents and scripts across scattered folders. A customer answer could take fifteen minutes instead of one.

    We built an internal CMS with embeddings-based semantic search and a chat interface that returns direct source citations. Everything behind the organisation's SSO.

    Streamlined information lookup and reduced operational friction for the support team.

    Brand website and automated booking system for luxury events.

    Form enquiries were handled manually by the owner. Most of his week went into quoting instead of running events.

    A site with a smart form that generates an initial quote automatically, checks live availability against the calendar, and forwards only qualified leads to the owner.

    Reduced repetitive manual work for the team and faster replies to customers.

    Status
    In production

    Operations platform with a CRM built from scratch.

    A service business with one-on-one sessions and long engagement programs needed a single system for clients, programs and documentation — instead of three generic tools that doubled the work.

    A conversion-focused interface that funnels toward a discovery call, and a dedicated CRM wired to phone and WhatsApp that transcribes and summarises every session automatically.

    Site is live, CRM in daily use. Final KPIs published at end of first full quarter in production.
