Sirena

Um CRM de WhatsApp para equipes de vendas. Fizemos crescer para mais de 3.500 clientes em 25 países e depois vendemos para a Zenvia em 2020.

Começamos a Sirena em 2016 porque enxergamos algo óbvio que ninguém estava construindo: toda pequena empresa da América Latina já vivia no WhatsApp, e nenhuma delas tinha uma ferramenta de vendas que funcionasse ali. Então construímos uma.

Quatro anos depois vendemos a empresa para a Zenvia. As lições abaixo são as que sempre volto a lembrar, as que eu diria a mim mesmo em 2016 se pudesse.

Lessons

  1. Comece com o cervo. É o único animal que te dá opcionalidade.
  2. Rode sua empresa com um sistema operacional, não com seu humor.
  3. Esqueça CAC e LTV. Olhe para o payback period.
  4. Escreva o e-mail raivoso. Não o envie.

$ 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.
