5 days to PMF? Spin to win

Inspired by Google’s Design Sprint and adapted for early-stage founders trying to validate a product idea fast. The whole exercise takes a working week.

the five days

  • Day 1 — Map. Talk to experts, draw the customer’s process on a whiteboard. Identify the actual pain.
  • Day 2 — Inspire. Look at how other products solve adjacent problems. Sketch.
  • Day 3 — Decide. Pick the version you’ll prototype. Write a one-page product outline.
  • Day 4 — Prototype. Build a clickable mock with whatever’s quickest. Google Slides is enough.
  • Day 5 — Validate. Show it to five potential customers. Listen.

why it works

You compress two months of research, design, and gut-checking into a week. If the problem you’re solving is big enough, customers will be willing to pay just based on Google Slides — that’s the level of pain that justifies a startup.

If they aren’t willing to pay for the slides, the problem isn’t big enough yet. Better to find that out in a week than in a year.

resources

  • The Sprint book by Jake Knapp — original methodology.
  • Remote-first variants exist; the Miro template communities have several.

If you’ve tried this — what blocked the implementation in your team? The most common stuck-point I’ve seen is the prototype day, where teams over-engineer and miss the point.

$ what is this?

lauta.blog is a personal site by Lautaro Schiaffino — a serial founder. It collects what he's learned from building three companies (Rodati, Sirena, Darwin AI) and from living, plus a few side rooms (books, food, board games, portfolio).

$ how do I navigate?

Three ways:

  1. Tabs at the top of the terminal window (~ · sirena · darwin · rodati · whoami · portfolio · books · boardgames · food) click any to switch sections.
  2. Keyboard shortcuts — press ? to see all of them. g+s jumps to Sirena, D toggles dark mode, etc.
  3. Shell — click the + at the end of the tab bar to open an interactive shell. Try tree, ls darwin, cat sirena/lesson-1.md, open whoami, subscribe you@example.com, help.

$ what about the menu bar?

$ traffic lights work

The three dots in the title bar do something: red closes the window (icon appears on the desktop, click to reopen), yellow minimizes (pill at bottom of desktop, click to restore), green maximizes.
