Why EqualStack

A partner that works like part of your team

We keep teams small and senior, communicate plainly, and take responsibility for outcomes.

Senior engineers only

Every engineer on your project has years of production experience. No juniors learning on your budget.

Transparent communication

Weekly demos, a shared board and direct access to the people writing your code. No account-manager relay.

NDA & IP protection

We sign an NDA before detailed talks. Code lives in your repositories and the IP is yours.

Flexible engagement

Fixed price, time & material or a dedicated team. Switch models as your project changes.

Time-zone overlap

Daily overlap with the US, UK, Europe, the Middle East and Australia for calls and quick decisions.

Quality first

Code review, automated tests and CI on every change. We fix root causes, not symptoms.

Our process

A delivery process you can see into

Six clear stages, with a working demo every sprint and no surprises at the end.

  1. 01

    Discover

    Workshops to understand goals, users and constraints. You get a scope, estimate and risk list.

  2. 02

    Design

    Architecture, user flows and UI designs, validated with you before development starts.

  3. 03

    Develop

    Two-week sprints with a working demo every sprint and continuous integration.

  4. 04

    Test

    Automated and manual testing, security checks and performance testing before every release.

  5. 05

    Deploy

    Staged rollouts with monitoring, so issues are caught before your users notice them.

  6. 06

    Support

    Maintenance, monitoring and continuous improvement under a clear support agreement.
