AI Systems & SaaS
Custom SaaS development, CRM integrations, automated n8n workflows and BI dashboards: intelligence applied to your process.
The pain
Data scattered across ten tools that don't talk to each other, spreadsheets patched at midnight, and a team redoing the same manual work every day.
How we solve it
We build the missing software and connect what you already use: custom SaaS, CRM integrations, n8n automations and a BI dashboard that shows the business in real time. Built by someone who co-founded an AI from scratch (ZealPro).
What we deliver
- Custom SaaS and internal tools (Next.js / API)
- CRM integrations (HubSpot, RD Station, Pipedrive and others)
- n8n workflows and automations connecting your stack
- BI dashboards with the numbers that drive decisions
- Embedded AI: support, lead qualification and summarization
What we measure (and report monthly)
Frequently asked questions
What kind of AI systems does 4RED build?
Custom SaaS, internal tools, CRM integrations (HubSpot, RD Station, Pipedrive and others), n8n workflow automations and BI dashboards. The AI layer goes where it genuinely solves something: lead qualification, support, data summarisation and analysis. The default stack is Next.js with its own API, hosted on infrastructure you control.
How much does a custom SaaS or automation cost?
It is quoted per project, because there is no honest price list for software scope. Before any proposal we run a diagnosis call to map the current process, the volume and the integrations needed. From there you get a fixed scope with a timeline and a price, with no surprise hours.
Do you integrate with the CRM we already use?
Yes, and that is usually the first deliverable. We integrate with HubSpot, RD Station, Pipedrive and anything with an API. When there is no API, we solve it with n8n automation. The goal is not to replace your tools: it is to make them talk to each other and show the whole funnel in one place.
Why does a marketing agency build software?
Because 4RED runs its own SaaS in production. Zeal Pro, Brazil's first Christian AI, has over 2,400 active leaders and recurring subscriptions, and was built by the same team. We also built Radar, our own visibility diagnosis engine. It is not outsourced and it is not a promise: it is what we do every day on our own product.
