The founder collection

Start with the evidence-based report. The model, supplier pack, legal brief, and reservation protocol are the pieces needed to move from research into a real two-city test.

The complete evidence-based founder packet

All fourteen final files in one portable ZIP. Start here if you want to hand the work to someone else.

Evidence-based founder report

Financial model

Fifteen sheets for Cascais and Porto, low/base/high costs, supplier evidence, paid demand, timeline, and gates.

Supplier discovery and RFP pack

Same-scope bid requests, caps, scorecards, and disqualifiers for both cities and every major partner.
