Gold Plan

How long is a piece of string? A rough guide is a simple proof of concept may cost between £0 and £5,000 and typically takes 4–8 weeks, while a minimal viable product (MVP) usually ranges from £5,000 to £20,000 over 8–12 weeks. A full application can cost between £20,000 and £50,000 and take around 3–6 months to develop. More complicated applications often fall in the £50,000 to £100,000 range with timelines of 6–9 months, while complex business platforms can exceed £100,000 and take 9 months or more. Ultimately, the final cost depends on factors such as features, integrations, scalability, and ongoing support requirements.

We typically work with SMEs and niche businesses that need custom software to solve complex problems and scale efficiently.

Threat modelling begins with understanding your system and the risks it faces. While it starts before any code is written, it’s revisited throughout development to address emerging risks. It involves the development team planning how data will flow through the system. They identify potentially sensitive data, such as personal or financial information, and define trust boundaries – points where data crosses between components or users with different levels of trust. Anything crossing a trust boundary is treated as potentially untrusted, requiring security controls like authentication, encryption, and input validation.

Project timelines vary based on scope, but we provide clear estimates during the discovery phase and follow agile processes to deliver efficiently.
