Production AI Agents for Vertical SaaS

We architect, build and operate multi-agent systems that turn human bottlenecks into 24/7 automation. Real production. Real paying clients. Real results.

Built with a production-grade AI stack

About

Altweb.ai is a Brazilian AI agency that designs, ships and operates production multi-agent systems. We focus on vertical SaaS — turning domain-specific human bottlenecks into reliable 24/7 automation.

What We Do

Engineering disciplines for production AI

AI Agent Engineering

From concept to production. We design agents using Pydantic AI, LangGraph, and the Cole Medin AI Agent Mastery methodology — built for reliability, not demos.

Multi-Agent Systems

Supervisor patterns, tool-calling orchestration, long-term memory pipelines, and deterministic guardrails. We build agents that scale to thousands of conversations.

Production RAG & Memory

pgvector-backed retrieval over domain-specific corpora. Extract → Dedup → Insert memory pipelines. Real-time conversational context that remembers users.

Process

How we ship production agents

step 01

Discover

Map the bottleneck and define success metrics. Without a measurable target, no AI investment is defensible.

step 02

Architect

Design the agent topology and data flow. Tools, sub-agents, memory boundaries, and deterministic guardrails specified up front.

step 03

Build

Implement, test, instrument with Langfuse. Every prompt, tool call, and retrieval is observable from day one.

step 04

Operate

Deploy, monitor, iterate based on real usage. Production data is the only honest feedback loop.

Case Study — NITA

WhatsApp AI nutrition assistant for a Brazilian wellness brand

NITA delivers personalized clinical nutrition through WhatsApp at scale. A multi-agent system orchestrated by a main agent that routes intent across 18 specialized tools — RAG over a 597-food nutritional database, three sub-agents for plan generation, multimodal photo analysis, and recipe suggestions, plus long-term memory backed by pgvector.
