The problem

Demos impress for a week.Production systems pay for years.

Another chatbot.
Another dashboard.
Another agent demo.
Another wrapper around an API.

The internet promised infinite possibility and somehow delivered infinite variations of the same thing.
Every startup. Every agency. Every demo day.

01
Burned by demos
An AI partner shipped a prototype. It broke the first week real users touched it.
02
You rent your tools
Per-seat pricing across ten different apps. The bill grows every quarter, and none of it is yours.
03
Roles stay open
Six months trying to hire senior engineers while competitors ship.
04
Nothing connects
CRM here, ERP there, spreadsheets in between. Every tool a dead end.

The gap isn't AI capability.
It's getting something real into production.

That's what we do.

Open case

DOSSIER · 0046

Architecture

Next.js 16 + React 19 frontend with Prisma ORM and PostgreSQL backend. 87 API endpoints covering member management, subscription billing, class scheduling, and payment processing. Claude Agent SDK powering WhatsApp AI receptionist for 24/7 member support. Retention monitoring system that detects engagement drops and triggers automated re-engagement workflows. Landing page with structured data for Google and ChatGPT ranking.

Key decisions

AI-first approach for member interactions (24/7 without staffing costs)
WhatsApp as primary channel (members already use it daily in Mexico)
Proactive retention monitoring (detect churn before it happens)
Structured data for Google and ChatGPT local search ranking
Prisma ORM for type-safe database operations across 87 endpoints

Before

Invisible on Google and AI search, manual follow-ups for bookings and retention, silent churn with no warning

After

Discoverable through Google, ChatGPT, and AI assistants. AI-powered automation handles routine member interactions. Proactive re-engagement recovers lost members before cancellation.

Method

How we deliver

01
Discovery and audit
Week 1
Feasibility, architecture, risk, and where the budget actually goes.

Scope and plan
Continuous
Roadmap, milestones, and a spec you can hold us to.
03
Build
Weekly sprints
Weekly working software. Staging access. No status theater.
04
Launch
Ongoing
Production deploy, docs, monitoring. Ongoing support included.

PRINCIPLE 01

We ship working software every week, not status reports.

PRINCIPLE 02

You own the code, the infra, and the decisions.

PRINCIPLE 03

If it does not move the business forward, we do not build it.

Hire

How to work with us

Three ways forward.

01
Build
SCOPED
Scoped project, fixed price
Ship something real.
A production system that needs to exist. Price agreed before we start, delivered live.
02
Embed
MONTHLY
Monthly retainer, dedicated team
Keep shipping.
A senior engineering team inside your company. For what you spend on SaaS seats, we build and operate your own system.
03
Evolve
ONGOING
Custom engagement
Evolve what you already have.
A system nobody maintains? We take over development and operation — evals, monitoring, weekly iteration.
