Sudo Software

Sudo is a digital product studio based in São Paulo, Brazil. We design, build and launch
custom software — web platforms, mobile apps, SaaS products and MVPs — for companies that
need a product in the market, not a slide deck about one.

What makes us different is that we are our own hardest client. Alongside client work we
design, ship and operate our own software products: Crowly (a SaaS that monitors how often
a brand appears in AI answers across ChatGPT, Gemini, Claude, Perplexity, Grok and
DeepSeek), Softdex (a B2B marketplace connecting companies to vetted software houses),
Parly and Presto (WordPress plugins for multilingual translation and for forms/CRM), and
Kanjica (a mobile app for Brazilians studying Japanese). Every one of them is live and
maintained by the same team that would work on your project.

That matters for a simple reason: we carry the cost of our own architectural decisions.
When we tell you a feature is not worth building yet, it is because we have paid for that
mistake on our own products first.

How we work:

• Fixed scope, timeline and price, agreed in the proposal — no open-ended hourly drift.
• The smallest version that already delivers value goes live first. Every screen has to
justify why it exists.
• Instrumented from day one. Real usage drives the roadmap, not opinion.
• Direct access to the people writing the code. No account-manager relay.

We deliberately take on a limited number of client engagements per year so each one gets
senior attention from start to launch. If you have a product that needs to exist, the first
conversation is free.
