From a sentence spoken in a business to a working function
The main task in this role is translation. A business describes its problem in its own words. Out of that comes a technical concept, a project structure and finally a function that gets used day to day. Five examples from the BLUNATECH platform.

What the business says
After every trade fair we lose half of the contacts.
What was built from it
Contact Booster with a QR code
A QR code leads to a form. The matching visual for posters and social channels is generated along with it, so the code actually gets seen.
3 export formats: story, landscape, square

What the business says
We simply run out of ideas for what to write about.
What was built from it
Editorial desk with prompts and formats
Topic prompts arrive sorted by category and are turned into the output format you need. The business picks from options instead of facing a blank sheet.
8 categories, 5 output formats
