AI Stack Generator

Describe the business. Get a stack.

One sentence about what the business sells and what it wants. The generator puts real catalog tools on the canvas, connects them, fills in how each connection runs, and writes down what it assumed.

Loop, 15 seconds, no sound: a sentence about an online outdoor-gear shop is typed into the AI Stack Generator, Generate is clicked, and the stack appears on the canvas with every connection documented.

Vendor RFIs, from draft to decision

Draft the RFI from your stack and send it to up to five vendors. The reminders do the chasing. Vendors answer question by question, on the page or in an Excel workbook. Your team scores the answers side by side. And the decision is written down with its reason.

Renewals you see coming
