“fiz o licitacerta sozinho com claude code e ele passou de R$ 10 mil em 30 dias.”
Editor's note: Amounts are in Brazilian reais (R$), not US dollars. His Sep 30 English post said '81 paying customers in 25 days', while the Oct 11 timeline says 100 customers by day 25; we show both as stated. He also gives away a free prompts PDF; that is not part of this case.
How they got customers
Paid ads from day one: in week 1 each sale cost about R$ 90 in ads for a R$ 49 product (founder's Oct 11 post). He also mentions an affiliate program with accountants and lawyers.
Steps to try
Go where businesses already pay; here, public tenders that small firms find out about too late.
