lautaro@wilsf — bash — ~

I've spent the last decade building three companies in Latin America — Rodati, Sirena (acquired by Zenvia in 2020), and Darwin AI — and helping my mother become a creator. Each one taught me things I wish I had read before I started. This is the index.

Each lesson is a short, self-contained essay. Read the ones that look useful; ignore the rest. Daily notes on the newsletter. Process notes at /colophon.

Darwin AI

2023–present

AI sales agents for SMBs across Latin America. WhatsApp, Instagram, and phone — the channels small businesses actually use.

  1. 01Build AI from LatAm. Don't apologize for the region — use it.
  2. 02Be the Dumb CEO
  3. 03Most founders think they're tier 1. They're tier 2 at best.
  4. 04If you're over 30, manage your prefrontal cortex
  5. 05Build for a world where every customer gets their own software
  6. 06The only AI moats in LatAm are local data and regulation
  7. 07You're not competing against AI. You're competing against the person who uses it well.
  8. 08Let humans do human things
  9. 09Build like you're sailing. Never bet against AI.
  10. 10Position yourself in the middle of the meta sandwich
  11. 11Veto anyone on your team who doesn't believe AI keeps getting better
  12. 12AI models are gravity fields. Your prompts are masses.
  13. 13Software is now non-deterministic. Be the human who's responsible.

Sirena

2016–2020

A WhatsApp CRM for sales teams. We grew it to 3,500+ customers across 25 countries, then sold it to Zenvia in 2020.

  1. 01Start with the deer. It's the only animal that gives you optionality.
  2. 02Run your company on an operating system, not on your mood.
  3. 03Drop CAC and LTV. Look at payback period.
  4. 04Write the angry email. Don't send it.

Rodati

pre-Sirena

A vehicle marketplace in Argentina. My first real operating role — where I learned what running things actually means.

$ what is this?

whatilearnedsofar.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.
