Why 72 Days?

In under 3 months you can turn an idea into reality and start learning valuable lessons about your product.

What's in a name?

72 Days may sound like a pretty arbitrary number, but in our experience it represents a realistic timeframe for creating an initial end-to-end product that offers genuine utility to users and provides an invaluable feedback point to measure against the wider product goals and objectives.
Number 72

Why choose us?

With hands-on experience building apps for both small-scale start-ups and giant-scale behemoths, we have the all-round knowledge you need to get from idea to app store (Apple and Google Play) and the experience to pick the right technical solutions to get you there.
Why us

IR30 what?

At 72 Days we think the IR35 legislation is a move in the right direction for the IT industry. We are here to provide a bona fide expert service, not an 'employee-as-a-service'. We will use our experience, tools and best practice to create awesome products for you. We prefer to build strong client relationships without middlemen and deliver solutions rather than timesheets.

Upfront pricing

Fixed scope - we are happy to dive in to the detail of what you need up-front and agree exactly what you will get for a fixed fee. Fixed budget - we can plan within your budget to help refine your idea into a deliverable feature set, including letting you know if the gap between what you want and what you have is too big!
Scales with money on one side, app stores on the other

Keen lean coding machines

An over-used term and an under-practiced methodology - we are keen advocates of the Lean startup principle of validated learning and believe the best way to do that is to get your MVP in the hands of real life users as effectively and efficiently as possible.

Why not partner?

We are passionate problem solvers first, expert code warriors second and as such are always on the lookout for "those little ideas" that could have a big impact on the wider world. If your idea ticks all the right boxes but your budget doesn't, we are more than happy to discuss alternate commercial approaches.
