How we work

Four stages, clear boundaries, and a system your team can run

A data & AI team only works if it behaves like your own: a straight answer on whether to build before how, an architect on the first call, a demo every two weeks, and everything handed over as yours at the end.

Four stages at a glance

One numbering everywhere on the site: Free intro call, 01 Discovery Phase, 02 Build, 03 Run. The details are below.

  1. Free

    Intro call

    Where you are, what you want to achieve, and whether we are the right fit. If we are, you get a Discovery Phase proposal sized to your project.

    1 hour · architect
  2. 01

    Discovery Phase

    An audit of what you have, or a plan for what you need: interviews, target architecture, requirements, timeline, estimate and risks. The result is yours.

    Fixed · USD 5k–15k
  3. 02

    Build

    The plan from Discovery, delivered with your engineers on your cloud account. A demo every two weeks, a weekly call, a monthly budget summary.

    Fixed · T&M · retainer
  4. 03

    Run

    Handover with training and documentation. Your team runs it, or we stay on for maintenance and monitoring if that is the strategic choice.

    Your team · or ours

Four things you can hold us to

Commitments you can check in the contract.

  • 02

    Whether before how

    Technology is a tool. Before we talk about how to build something, we ask whether it should be built at all: legally, clinically, commercially. If the business case doesn't close, we say so as early as we can, before you spend on a build.

  • 03

    A physician in the process

    When a project touches clinical workflows, our Chief Medical Officer is part of it from the start, not a reviewer bolted on at the end. Labeling protocols and what “good enough” means at the bedside get decided with a doctor in the room.

  • 04

    Everything is yours

    Code, models, cloud account, documentation: on your side, in writing. We build so your team can run the system without us.

From first conversation to production

Each stage has a clear boundary: what happens, what you get, and what belongs to the next stage. You can stop after any of them and keep everything produced so far.

Free

Intro call

1h with an architect

It starts with a short brief, the form on our contact page, and an hour-long call with one of our architects, sometimes a follow-up. There is no script: the conversation follows what you're building and how far along you are. If you know what you want and why, we talk about how it could be built and what a Discovery Phase would cover. If you don't yet, we talk about what it would take to find out.

This is a conversation, not a quote: technical and business at once, and the moment to say whether we are the right team for it.

What we talk about
  • Where you are and what you want to achieve
  • What you have: data, systems, team, timeline
  • Whether we are the right fit for it
  • What a Discovery Phase would cover, and its price
Not included – that's the Discovery Phase

The ROI analysis, the technical path, a review of your data and regulatory situation, a specification, estimates per module, audit findings or architecture design. The intro call ends at the fit; the Discovery Phase starts after it.

01

Discovery Phase

Fixed · USD 5k–15k

The Discovery Phase goes deep where the intro call stayed wide. We formalize the goals we talked about, then concentrate on the technology: how the system should be architected, what it must do, and what it must satisfy that no user ever sees – security, HIPAA/GDPR, uptime. Complex systems take longer than four weeks, and we'll say so before you sign.

Discovery comes in two shapes. A – a new system: we design it. B – an audit: you already have something, and you want to know what's sound, what's broken and what to fix first.

A · New system – what we produce
  • Target architecture and the data flow through it
  • Functional and non-functional requirements (security, compliance, performance, uptime)
  • Timeline, estimate and the recommended order of work
  • Risk register and the tooling we propose
B · Audit – what we produce
  • An honest assessment of the existing system: what's sound, what's broken, what's fine
  • Recommendations and a remediation plan – which you can run with us or without us
02

Build

Fixed · T&M · retainer

We build iteratively, against the milestones set in Discovery, and we build with you: your engineers are in the reviews from day one, so the result is co-created rather than delivered. How long it takes depends on scope – we'd rather tell you after Discovery than guess on a sales call. Current projects run from a few months to a year.

The commercial model is your choice: fixed scope when it's clear, time & materials with a budget cap when it isn't, or a monthly retainer for longer programs.

The cadence
  • Weekly – a working call with your team: what's blocking us, what we need confirmed, what we're thinking
  • Every two weeks – a demo of working software, not slides
  • Monthly – a summary for the budget holder: where we are against the estimate, over or under, and what's next
  • Ad hoc – more calls when a decision can't wait
03

Run

Your team · or ours

When the system is finished and its metrics validated, we hand it over properly: training, onboarding, documentation. You have full control – the system is designed to be operated by your team, so you never depend on us as a vendor.

Two paths from here. Your team runs it – the default, and the reason we document the way we do. Or, if running it isn't something you want to own for strategic reasons, we stay on for maintenance and support under a separate agreement.

What you own at handover
  • All code, models and infrastructure definitions – in your repositories, on your account
  • Documentation written for the people who will operate it, and for the auditors who will ask about it
  • A trained team: onboarding sessions before we step back
  • Validated metrics – what the system does, measured

We don't start from zero

Components proven across 25+ healthcare projects give every new one a running start: tested, documented, and adapted to your case rather than forced on it. You own the result.

  • MLOps platform template: training, registry, monitoring, audit trail
  • HIPAA/GDPR landing zone on AWS, as infrastructure as code
  • DICOM and HL7 FHIR ingestion pipelines with de-identification
  • Medical labeling tooling built on 3D Slicer with our own backend
  • Data and ML validation framework for FDA and EU MDR
  • Security scanning components for pipelines, containers and cloud accounts

Practical answers before you ask

Most of our clients are in the U.S. Here's how that works day to day.

  • Meetings in your time zone; a daily overlap window with your project team
  • NDA before the first file leaves your systems; patient data stays in your cloud account
  • Contracts in USD; BAA signed where PHI is in scope
  • IP and code ownership transfer to you on payment, in writing
  • References on request: a global orthopedic medtech company, Carta Healthcare, Navv Systems

Questions we get on the first call

What does the intro call cost, really?

Nothing, and there's no catch, but there is a boundary. The intro call tells you whether we're the right fit and what a Discovery Phase would cover. The analysis itself, from ROI and technical path to specification and estimates, is the paid Discovery Phase.

How much is the Discovery Phase?

A fixed price: USD 5k, 10k or 15k, depending on the scope – a standard analysis and a complex system are not the same job. If the number doesn't fit your budget, you'll know on the intro call, not after three.

Do you design user interfaces?

Rarely. We build the engines – data flow, models, integrations – and many of our systems have no interface at all; they plug into yours. When a product needs one, we build it or integrate with your front-end team. We don't produce mockups in Discovery.

Do you work fixed price?

Yes, when scope is clear – usually after Discovery. Before that, time & materials with a cap, or a retainer. We'll recommend the model that fits the uncertainty in your project, not the one that's best for us.

Who owns the IP and the code?

Everything built for you is yours: code, models, documentation, to keep, change and run without us. Our reusable components, which make delivery faster, come with an unlimited license.

Can you work inside our cloud and with our engineers?

That's the default. We build on your account, in your repositories, with your team in the reviews – that's the co-creation we mean, and it's why they can run it after we step back.

What do you do for an FDA or EU MDR submission?

We don't write the submission; your regulatory team does. We make sure the system can answer its questions: data lineage, training records, validation results, change control, and documentation a reviewer can read.

How fast can you start?

The intro call happens as soon as an architect has read your brief. The Discovery Phase usually begins within a couple of weeks after that. Build timelines come out of Discovery, not out of a sales call.

What if AI turns out to be the wrong tool?

We'll say so as early as we can, often on the intro call, and suggest the cheaper thing: a data pipeline, a report, a rules engine. Several of our best client relationships started with “not yet.”
