Results in numbers

Real numbers from accounts I've managed. Client names are kept confidential.

  • 7+ years in paid media

  • 19,300+ leads generated

  • MXN $95M in reserved unit value (≈ US$5M)

  • MXN $1.7M monthly ad spend managed in a single account (≈ US$90K)

  • −20% cost per lead, month over month

The problem

More leads doesn't always mean more sales.

Plenty of accounts celebrate a low cost per lead while the sales team complains nobody picks up the phone. The problem is rarely the budget. It's what gets measured, what gets optimized and what gets overlooked.

  1. “I’m spending, but I don’t know what works.”

    Reports full of metrics that never connect to revenue.

  2. “I get leads, but not deals.”

    The platform optimizes for volume, not quality.

  3. “My data doesn’t tell the whole story.”

    Pixel without Conversions API, duplicated conversions, data that never reaches the CRM.

The good news: all of this can be measured, fixed and scaled. Here's how I do it.

Services

How I help you sell more with the same budget Four services, one goal: make every dollar work all the way to the sale.

  1. Find out what's holding your results back.

    I review structure, tracking, audiences, creatives and budget allocation. You get a clear diagnosis and a prioritized action plan.

  2. Full-funnel campaigns that scale with control.

    I plan, launch and optimize across Meta Ads, Google Ads, YouTube, LinkedIn and TikTok, with A/B testing and budget forecasting.

  3. Measure what really matters: sales.

    I connect Pixel, Conversions API, GTM, GA4 and your CRM so campaigns optimize for qualified leads and closed deals, not just form fills.

  4. AI-powered media buying

    What sets me apart

    Faster decisions, backed by more data.

    I connect Claude to Meta Ads through MCP to analyze, spot opportunities and automate reporting in real time.

AI applied to media buying

AI doesn't replace a great media buyer. It makes them faster and sharper.

Everyone's talking about AI; I use it every day on real accounts. I connect models like Claude directly to Meta Ads through MCP (Model Context Protocol), a standard that lets AI read your live campaign data and work with it. The result: fewer hours building reports, more time making decisions.
