Who is behind this

SigmaFlowAI is an AI-first agency founded in Portugal. We bridge backend logic and frontend beauty — the same care you see in this studio goes into every delivery.

The person who answers, designs and builds is the same one: founder and software architect. No account-manager layers, no telephone game between what you ask and what gets built.

House rule: real proof over promises. If it is on this site, it exists, it runs in production, and the client confirms it.
