Software and apps, built for the businesses that depend on them.

Supreme Digital Ventures is a development company in London. Other businesses come to us to design, build, and ship mobile apps and web software, and to run the cloud infrastructure underneath them.

Services

Four things we are hired to do

Most engagements are one of these, or a project that starts as one and grows into another.

01

Mobile apps

iOS and Android from a single codebase, taken all the way through review and onto both stores.

  • React Native and Expo, TypeScript throughout
  • App Store and Google Play submission, and the rejections that come with it
  • Subscriptions and in-app purchases, verified server-side
  • Offline use, push notifications, deep links, share sheets

02

Web and product software

Customer-facing web products, and the unglamorous internal tools a business actually runs on.

  • Web front ends and dashboards
  • APIs, webhooks, and third-party integrations
  • Postgres data modelling and migrations
  • Accounts, permissions, and payments

03

Cloud and infrastructure

Somewhere for the software to run that you are not afraid to touch on a Friday afternoon.

  • AWS: containers, managed Postgres, object storage, CDN
  • Infrastructure created by scripts that can be re-run, not by clicking in a console
  • Deployment from your repository on merge
  • Logs, alerts, and a monthly bill somebody can explain

04

Technical consultancy

A straight opinion, in writing, when the decision is expensive and nobody in the room is neutral.

  • Build, buy, or leave it alone
  • Architecture and cost review
  • Assessment of an existing codebase or supplier
  • A plan specific enough to hand to whoever builds it

Capabilities

What we build with

A deliberately small stack. We would rather know a handful of tools properly than claim all of them.

Mobile

  • React Native
  • Expo
  • TypeScript
  • Gradle
  • Xcode
  • App Store Connect
  • Google Play Console

Web and services

  • Node.js
  • TypeScript
  • React
  • HTTP APIs
  • PostgreSQL
  • Docker

Cloud and delivery

  • AWS ECS Fargate
  • Amazon RDS
  • S3
  • CloudFront
  • Cognito
  • Secrets Manager
  • GitHub Actions

Applied AI

  • Anthropic Claude
  • Amazon Bedrock
  • Structured extraction
  • Vision and OCR
  • Cost and quota control

We also read code we did not write. Taking over a half-finished project is normal work here, and it starts with an assessment rather than a rewrite.

How we work

From first email to handover

Every engagement runs in this order, whether it is four weeks or four months.

  1. 01

    Scope, in writing

    A call, then a short document: what we are building, who it is for, what finished means, what it costs, and what is explicitly not included. Nothing starts before you have read it.

  2. 02

    Design and build in cycles

    Short cycles, each ending in software you can open rather than a progress report. Scope can change between cycles; that is the point of working this way.

  3. 03

    Ship it properly

    Store review, production infrastructure, monitoring, and a release run at least once with your team watching, so a deployment is never a thing only we can do.

  4. 04

    Handover, then support if you want it

    Source code, accounts, credentials, and documentation are yours. Keep us on a retainer, move it to your own team, or hand it to another supplier. All three are fine, and none of them require our permission.

Engagements

Three ways to work with us

Fixed-scope project

A defined piece of software for a defined price, from the scope document. Best when you know what you need built.

Monthly retainer

Continuous development, maintenance, and releases for an agreed monthly amount. Best after launch, or when the roadmap is still moving.

Advisory

Days bought individually for review, due diligence, or a second opinion. No build work, no obligation to hire us for one.

Price is quoted per engagement, after the scoping call. We do not publish day rates we would have to caveat on the phone.

Questions

Asked before the first call

Who do you usually work with?

Founders and small teams who need something built, and established companies who need extra hands or an outside opinion. Clients are in the United Kingdom and abroad.

Will you take over an existing codebase?

Yes, and often. We start with a read-through and a written assessment: what is there, what is load-bearing, what is risky, and what it would cost to continue versus replace. You get that assessment whether or not you continue with us.

Who owns the code and the accounts?

You do. Repositories, cloud accounts, and store listings are created in your organisation's name wherever the platform allows it, so nothing important is hostage to our involvement.

Can you publish an app under your developer account?

We can, but under yours is usually right: the listing, the reviews, the ratings, and the subscription relationships stay with the account that published them. If you do not have one yet, we will set it up with you.

Do you sign NDAs?

Yes. Send yours with the first email, or ask and we will send a short mutual one.

How does a project actually start?

An email describing the problem. If it is something we can help with, a call; if it is not, we will say so and point you elsewhere. Then the scope document, then the work.

Contact

Tell us what you are building.

A paragraph about the problem is enough to start. Every enquiry is read and answered by a person.
