Findabis: Medical cannabis platform, directory and website builder

Featured project

Findabis

Medical cannabis platform, directory and website builder

Findabis is the platform we designed and built for UK medical cannabis: a public directory of clinics, pharmacies, products, strains and brands, and the software those businesses run on behind it.

Medical cannabis

The UK's leading technology company for medical cannabis

We built Findabis, the platform UK medical cannabis runs on. Clinics, pharmacies, brands and suppliers work on one system, from a patient's first eligibility check to the batch a pharmacist dispenses. Harley Street clinics, licensed pharmacies and international brands trust us with their websites, patient pathways and compliance.

  • The whole prescription chain

    Clinic, pharmacy, brand and supplier each get their own workspace, with patient portals, iOS and Android apps and an AI layer on top.

  • Compliant by design

    An unlicensed medicine may not be advertised in the UK. Every site we build says what the law allows and nothing more.

  • Proven at scale

    267 data models and 21 white-label themes, running live sites for clinics, pharmacies and brands across the UK and beyond.

Our story

We turn ideas into companies

Some were ideas people brought to us. Some we had ourselves. All of them became real products.

  1. Their idea, built solo

    Leviathan FM

    A financial markets research platform that began as an idea someone brought us. Tyler built it on his own and became a founding member.

  2. Their idea, built together

    The Wyze

    Another founder's idea that we helped grow into a full property platform. Tyler became one of its main founders.

  3. Our own company

    Findabis

    Our own UK medical cannabis platform, and the reason we lead the sector: it powers the websites and patient portals of clinics, pharmacies and brands.

  4. Launching January 2027

    ResBoost.ai

    Tyler was given an idea for a property site and, single-handed, turned it into a new AI property portal for the UK.
