(Agency · Est. 2024 · Jávea, ES)

We build the that makes businesses compound.

GBCB is a small, opinionated team shipping AI-native marketing, custom agents and the plumbing between them. No decks. No retainers that go nowhere. Just leverage.

01 — What we do

Three disciplines. One operating system.

S/01

AI Solutions

Custom agents, RAG over your data, evaluations that don't lie. We ship models that work on Tuesday morning, not just in demos.

Agents RAG Evals Fine-tuning

S/02

Marketing

Positioning, content engines, paid systems. AI-native funnels that learn faster than your competitors' agencies bill.

Brand Content Paid Lifecycle

S/03

Integrations

APIs, webhooks, internal tools, the pipes between your CRM, your warehouse and your inbox. Boring on purpose. Reliable by design.

APIs Webhooks Pipelines Internal tools

02 — How we work

Four weeks from kickoff to compounding.

Map

Two days. We tear apart the workflow, the data, and the politics. You get a diagram and a number.

Prototype

One week. A working slice running on real data. Ugly, fast, honest. We learn or we kill it.

Ship

Two weeks. Production-grade. Monitoring, evals, handoff docs. Your team owns it.

Compound

Forever. We stay on a thin retainer to tune, extend, and break things on purpose.

03 — Selected work

05 — Manifesto

M/01Decks don't ship.

M/02AI is a material, not a meeting.

M/03Boring infrastructure beats clever demos.

M/04Measure twice. Ship. Measure forever.

M/05Small team, sharp opinions, fewer clients.

M/06If we can't make it compound, we won't take it.

06 — Contact

Let's build something disgustingly effective.

We take on three to five engagements a quarter. Write a paragraph. We answer within a day.
