Our work

Applications, websites and AI tools that change the daily life of the people who use them.

Here is what we delivered, with the numbers. Every project starts from a precise problem and a measurable result.

Our work

  • Concerts · iPhone and Android

    CrowdMate

    3,963 concert venues, updated every week.

    An app published on the App Store and Google Play, fed by a collection of venue listings across 189 cities and by a pipeline that produces the city guides.

    • City guide pipeline
    • App Store + Google Play
  • Citizen participation · Missions Publiques

    ECP Companion

    150 European citizens, 24 languages: an app strengthened, then extended.

    The nontechnical Missions Publiques team had built the European citizens’ panel app with AI. In 3 months: stronger foundations, new features, real-condition testing and a development method the team keeps.

    “The panel’s first session went very well, and his support clearly contributed to that.”

    She Tutors

    70 hours a week of manual admin, replaced by a booking link.

    Each family gets a private link and books in 2 clicks. The Google Meet invitation goes out by itself, payment is taken by card in advance, and so are the no-show emails.

    • Automatic Meet
    • Card prepayment
  • Executive coaching · Dr Markus Hasel

    MCHasel Consulting

    100/100 for accessibility, best practices and SEO.

  • Law · Anonymous client

    Paris law firm

    97 corrections in 32 files on a site its agency thought was fine.

    Her agency said "we're happy with the numbers". We found typos, dead links and Lorem ipsum, then redirected the broken addresses.

    "You are by far the most competent of all the 'web pros' who have approached me…"

    Demurrage

    Every hour of demurrage can be justified.

    AI reads the scanned Statements of Facts. A deterministic engine computes laytime under the charter-party rules: the calculation never comes from the model.

    • Scanned SOF → statement
    • Tested deterministic engine
    • Auditable line by line
