About Pol

You have multiple dashboards. But when your CEO asks you, "Are we going to meet the goal?" or "Is this campaign working?"... you're not sure. You spend hours in Excel cross-referencing data, arriving late to insights, reacting instead of leading.

Here's the problem: Your dashboards show you data. They don't tell you WHAT to do or WHEN to do it.

I FIX THAT.

I'm Pol, a Power BI consultant who helps Sales and Marketing Directors build dashboards that don't just report, but guide. Dashboards that tell you: "Salesperson X is having trouble with demos, train them THIS WEEK" or "Campaign Y has a 3x better ROAS, reallocate budget NOW."

BECAUSE I UNDERSTAND:

I didn't start as a technician. I started by leading sales teams at Cabify and Housell. I was drowning under the pressure of meeting goals without any visibility into what my team was actually doing. Nobody built the dashboards the way I needed them, so I learned Power BI myself, out of necessity, not theory.
That gave me something most Power BI consultants don't have: I've been on the other side. I know what a Sales Director needs because I was one. I know what drives Marketing Managers crazy because I've worked closely with them.

HOW I WORK:

→ I start with decisions, not data. What do you need to know every day to meet your goals? What actions will you take based on what you see?

→ I question your current setup. If I see a better way, I'll tell you. I'm not here to build what you asked for, I'm here to build what you need.

→ Fixed price, clear process. You know exactly what you'll pay, what you'll get, and when.

→ Dashboards that get used. I don't build pretty reports that nobody opens.

Stop spending hours in Excel. Stop reacting to problems when it's too late. Start being the proactive, data-driven leader you always wanted to be.

It has been a pleasure working with Pol. Beyond the personal treatment, which has been excellent, and having had the opportunity to meet him in person, Pol has proven to be a great professional. The task we have carried out with him was highly complex, and Pol has put a lot of effort into making everything work out. We could not be happier with his work and character. We recommend working with Pol 100%. Thank you, Pol. We hope to collaborate together again soon!
