AI-native GTM & Operations leader · Barcelona

I build the AI systems that grow and run a business.

14 years in growth, marketing and go-to-market, plus hands-on AI building. Ex-COO and CMO of Taclia, an AI-first operating system for SMBs. I decide where AI creates value and where it doesn't, build the agent myself, and measure adoption, cost and impact.

How I work

Business first. Then I build it.

1

Grow

Product-led growth, acquisition, lifecycle, pricing and attribution. Targets on acquisition, conversion, MRR and ARR.

2

Run

Operations, product, customer success and GTM under one roof. Process design, build vs buy, change management and adoption.

3

Build

LLM agents with tool calling, evals, model selection, fallbacks and cost control. I ship them myself with Claude Code.

Selected work · Taclia · 2023–2026

From Head of Marketing to COO.

Taclia is an AI-first operating system for SMBs, backed by €9.2M from Cusp Capital and Stage 2 Capital. I built marketing from scratch, ran it as CMO, then led operations, product, customer success and go-to-market as COO.

AI agents in production

Voice, WhatsApp and a copilot that acts

Voice agents that summarise every call and update the CRM. WhatsApp and email agents with business hours and human handoff. A copilot with tool calling across CRM, invoicing, inbox and stock that respects each user's permissions.

A small team shipping like a big one

A workflow where two people ship ~15 changes a day with coding agents in parallel: one workspace per agent, commit guards and drift checks across 190+ serverless functions and 1,400+ migrations.

~15 changes a day, 2 people
AI quality & cost

Reliable, measured, on budget

Eval harness for the copilot, monthly model monitoring, automatic fallback to a second provider, spend alerts at 80% of budget and credit-based usage limits.
