Before we begin
Questions about the engagement
Should we build a web app or a mobile app?
We look at how often people use the product, the devices they carry, distribution needs and requirements such as offline access or device features. The choice follows those needs.
Can you connect the app to our current systems?
We review API availability, authentication, data ownership and rate limits. Where an API is missing, we scope the integration work before committing to the release.
Can we launch a smaller first version?
Yes. We define a complete core journey for the first release and separate later features, while keeping the data model and integration decisions ready for expansion.
