Software development ยท London
One in three software projects fails because it was never de-risked. We build bespoke, robust and intuitive software that is de-risked from day one.
TRUSTED BY
200+ BUSINESSES
Who is accountable for the failure of a custom software project, and for de-risking it before it starts? Everyone. Our open communication makes everyone accountable from day one, on your side and ours, and the result is solutions that solve real business challenges and deliver a fast return.
Every company handles challenges and opportunities in its own way. We sit with you, map how you work and reflect it in your custom software.
We avoid surprises when the stakes are high. We sketch your solution so you can see it and suggest improvements before any code is written, and the team knows exactly what to build.
Custom projects are not cheap, so we optimise your spend with the right mix of people, technology, features and engagement model. You can see the difference clearly.
Because we know exactly what you want and what needs doing, everything is streamlined. That lets us deliver quickly and reliably while keeping quality high.
Our QA team helps developers fix issues and optimise the front end and back end of mobile, web and portal solutions, across 1,200 to 2,500 predefined touchpoints.
Our DevOps team works with your product manager on deployments that balance performance, robustness, security and scalability.

Our free one-day workshop helps you de-risk your existing IT ecosystem and projects already under way.
As organisations grow, so do their silos, until they cause delays, errors, poor visibility and loss of control. How do you regain control without ruffling feathers? This session answers these questions and more, and it is on the house.

On PremThey truly went above and beyond everything that we asked of them. In many ways it felt like they had become members of the team as they worked with us through a rigorous testing process to ensure that the app worked seamlessly.
I cannot recommend O2SOFT enough. They have been fantastic to work with, reliable and very knowledgeable about the whole app building and submission process.
A job well done. They are true professionals, quick to understand what is needed, think ahead, ask the right questions, respond quickly, and will do what it takes to ensure client satisfaction.
A great team to work with. Very flexible and understanding. They always made themselves available and provided great ideas in solving the many problems we encountered during the course of the project. Highly recommended!
Whether you are starting from an idea or rescuing something already in flight, the first conversation is free and useful either way.
