You decide how we work
A project starts with a vision, shaped by your goals, business needs, budget, and timelines. With 3,000+ skilled engineers at your service, we’re ready to turn that vision into reality. The only question is: how would you prefer to collaborate?
IT staff augmentation can solve the skill gaps, tight deadlines, budget limits, or sudden scaling needs. Vention supplies experienced engineers who seamlessly integrate into your team and work under your direction.
Our self-organised, dedicated teams will take on most software development activities. The autonomous nature of pod teams will minimise the management burden on your shoulders, but they will still ensure you keep control over the project’s progress.
We handle the entire project end-to-end, from discovery and requirements specification to design, development, testing, and launch. You concentrate on critical business tasks while we keep you updated on the progress of your solution development.
