Learn moreHow a project runs
Every engagement follows four phases, delivered through a six-step software development life cycle.
- 1
Initiation
We agree goals, constraints, team and communication plan, and sign an NDA.
- 2
Discovery
Requirements, architecture, prototype and a detailed estimate.
- 3
Execution
Two-week sprints with demos, QA and transparent progress reports.
- 4
Closure
Release, documentation, knowledge transfer and optional ongoing support.
Discovery
We clarify goals, users and constraints, then define scope, architecture options and a delivery plan with a clear estimate.
Architecture & design
Solution architecture, UX flows and UI design are agreed before development starts, so the build has no surprises.
Development
Two-week sprints with demos, transparent progress tracking and code reviews on every change.
Testing & QA
Automated and manual testing runs throughout development, not just before release.
Deployment
CI/CD pipelines, staged rollouts and monitoring take your product live safely.
Support & evolution
SLA-backed maintenance, performance tuning and new features as your business grows.
Beyond writing code
Customer experience
Research-driven UX that reduces friction and increases conversion and retention.
Digital transformation
Replace manual work and legacy tools with connected, automated systems.
Cybersecurity
Secure-by-design development, security testing and compliance readiness.

View caseCustom software development: FAQ
What is custom software development?
It is the process of designing, building and maintaining software for one organisation’s specific needs, rather than buying a generic product. You own the result and it evolves with your business.
How much does custom software development cost?
Cost depends on scope, integrations and team size. After a short discovery call we provide a fixed-price estimate for well-defined scopes or a monthly team rate for evolving products — with no hidden fees.
Who owns the source code?
You do. All source code, designs and documentation are transferred to you under the contract, and every engineer works under NDA and IP-assignment terms.
How long does a typical project take?
An MVP usually takes 8–16 weeks. Larger enterprise systems are delivered in phased releases so you see working software every two weeks.
