Ship the right systems.

Fourtix learns your business first: what you build, who it serves, and why. Then we ship production systems — grounded, gated, and observable — with a precision that feels unfair.

Domain Knowledge

Fourtix learns your company from the tools you already use — then builds AI grounded in your policies, data, and workflows.

Knows every system inside out.

Grounded, gated, and observable — every AI system defensible against hallucination.

Applied AI

AI that does measurable work — not demos.

Production AI is the differentiator that turns CRUD systems into advanced products. Here's the pipeline we ship with — grounded, gated, and observable.

Practices

Two verticals, one AI capability layer, an engineering foundation.

Applied AI is both a standalone practice and the layer embedded inside everything we build.

01

Healthcare Technology

Production healthcare software — from AI claim appeals to full practice management.

▪RAG over medical policy & payer guidelines
▪Multi-agent appeal generation (LangGraph)
▪Insurance benefits verification (VSP, EyeMed, Availity)
▪Optical / clinical quote calculation
▪Payment processing (CardPointe, Stripe)
▪Multi-tenant practice management

Grounded, gated, observable

Every AI system we build is grounded, gated, and observable.

Strict RAG grounding, human-in-the-loop review gates on high-stakes output, and full audit trails — defensible against the hallucination liability killing ungrounded deployments.

Retrieve→ Ground→ Generate→ Critique→ Approve

Autonomous agents

LangGraph multi-agent pipelines that plan, act, and self-check.

RAG & retrieval

Grounded over your documents, with strict hallucination thresholds.

Voice agents

Twilio + Whisper + LLM for booking, intake, and triage.

Document intelligence

Hybrid OCR + LLM — invoices, contracts, forms at scale.

Evals & guardrails

Groundedness checks and evals wired into CI, not bolted on after.

Turns CRUD into advanced products

The layer embedded inside everything we build — measurable, not a demo.

How We Work

Discovery to production, in tight loops.

01

Discovery

We map the problem, the constraints, and the fastest path to production.

02

Design

Architecture, data model, and the interface — decided before code.

03

Build

Tight weekly loops. You see working software, not status decks.

04

Ship

Production deploy with monitoring, evals, and human-in-the-loop gates.

05

Support

We maintain, monitor, and retrain — systems that last five years out.

"They didn't hand us a prototype and disappear. Fourtix shipped a system our billing team uses every day — and the appeals actually get paid."
