Case study
Fifteen days from idea to paying customers.
Nexora built Extrack, a money tracking product whose AI assistant can take 29 different actions on the owner's behalf, and carried it from idea to first paying customers in 15 days. Money tracking, subscription billing and the assistant all shipped in that window. The result is live at myextrack.com.

What it is for
Money tracking, with an assistant that does the entering. Most tools of this kind ask a person to be diligent every day; the ones that survive contact with real life ask for less than that.
What the assistant actually does
Twenty-nine actions, each one a thing the assistant can carry out rather than describe. That is the difference between a chat box bolted onto a product and an assistant wired into it, and it is the part that takes engineering rather than a prompt.
Why 15 days is the number to look at
Not a prototype, and not a demo. Fifteen days from idea to customers who paid — including subscription billing, which is the part teams usually leave until later and then discover is the hard bit.
What it runs on
Next.js, AWS serverless, subscription billing, and MCP for the assistant's tool calls. The same stack this studio uses for its own products.
