Twentieth Avenue

A senior engineer on your team, for as long as you need one.

Twentieth Avenue is a software consultancy and app studio. We take on a few software companies at a time, on ongoing engagements rather than one-off projects, and we build and publish apps of our own.

What we do

Software consultancy

Senior engineering and product development for software companies, on an ongoing basis. One engineer who stays with your product long enough to know it properly, and who can take a feature from the first conversation to production without a hand-off in between.

We work across the whole product: the interfaces people use, the services behind them, and the decisions about what to build next. We have worked with PosterMyWall, the online design platform, and we know what it takes to ship and maintain apps on the App Store and Google Play.

Our own apps

We design, build and publish mobile and web apps for the Apple App Store and Google Play.

The first apps are in development and will be listed here when they ship. If you would like to hear about them, write to us.

Capabilities

  • Web applications

    The interfaces people spend their day in: fast, reliable, and careful about the details users notice without being able to name.

  • Mobile apps

    Apps for iOS and Android, taken from idea to the App Store and Google Play, including store setup, releases and the maintenance that follows.

  • Back-end services

    The services, databases and integrations behind a product, and the operational work of keeping them boring.

  • Product engineering

    Working from a problem rather than a spec: measuring what users do, deciding what to build, shipping it and reading the numbers afterwards.

  • Existing codebases

    Joining a product that already has users and history, learning it properly, and improving it without breaking what works.

  • Long engagements

    Staying with a product for years rather than months, so decisions are made by someone who will live with them.

How an engagement works

  1. A conversation

    You tell us what you are building and where it is stuck. We tell you honestly whether one senior engineer is the right answer, and what it would cover.

  2. A monthly arrangement

    Engagements run month to month at a fixed rate, with a clear scope and no project estimates to argue over. Our current engagement has run for years.

  3. Work inside your team

    We work in your repository, your tools and your process, remotely and in any time zone. Code is reviewed, shipped and owned by you.
