Ten delivered products across three continents
Delivered for teams in Ireland, the United States, and Australia.
Outcomes, not adjectives
Selected work
Real products, in production, with real numbers.
The proof a services buyer actually wants. Each one shipped and running.
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.
Applied AI
AI that does measurable work — not demos.
Production AI is the differentiator that turns CRUD systems into advanced products. Here's the toolkit we ship with.
Grounded, gated, and observable
Every AI system we build has 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.
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.
How we work
Discovery to production, in tight loops.
Discovery
We map the problem, the constraints, and the fastest path to production.
Design
Architecture, data model, and the interface — decided before code.
Build
Tight weekly loops. You see working software, not status decks.
Ship
Production deploy with monitoring, evals, and human-in-the-loop gates.
Support
We maintain, monitor, and retrain — systems that last five years out.
The team
You're buying the three of us.
No bench engineers, no hand-off to juniors. The founders do the work.
“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.”

Let's build something that ships.
You'll talk to a founder, not a sales rep. Tell us what you're building and we'll tell you how we'd ship it.
