SigmaFlowAI

SigmaFlowAI builds AI systems that carry real operational weight: voice receptionists answering live phone lines, lead pipelines that move from first click to CRM without manual copying, internal tools, and automation across n8n, Python, and Claude. We are based in Portugal and work with clients internationally, in English and Portuguese.

The agency runs two service pillars under one roof. Operational AI covers the systems side: automations, integrations, AI agents, and the boring-but-critical glue between tools. Creative production covers the visible side: websites with real front-end craft, brand visuals, video, and marketing assets made with AI tooling and finished by a human eye.

What makes us different is simple: the founder is a software architect, and he is also the person who answers your messages, designs the system, and ships it. More than ten AI and automation systems run in production today across internal operations and client businesses, including a voice receptionist that has handled around 30 calls a month for a childcare business since March 2026, saving an estimated 12 to 15 staff hours weekly.

We assume every system needs an owner after launch, so maintenance is part of the offer. We build with GDPR in mind and disclose AI wherever it interacts with your customers. If that sounds like the way you want automation done, we should talk.
