Maria Bermudez · BermudezMedia
Your agency keeps the strategy and the client relationship. I run your clients’ Google Ads, Meta, LinkedIn and TikTok under your brand, using your tools and processes, with reports you can forward as they are.
I work in the background. Your client only sees your agency.

Hi, I’m Maria Bermudez, founder of BermudezMedia. I’ve spent 9 years in tech: first as a full-stack developer, then the last 4 as a paid media specialist. Before going freelance I worked at four agencies: Good Rebels, Growth Land, and Pantelope and Terra in the US. In total I’ve worked with agencies in the US, Sweden, the UK and Spain. I’ve managed up to $500,000 a month in a single Google Ads account. Today, I work alongside your team to run your clients’ campaigns under your brand.
I'm based in Madrid and work remotely with agencies across Spain, the rest of Europe, Latin America and the United States. I work in Spanish or English and adapt my schedule to the client's time zone, including the East and West Coasts.
You won't find their names here. I work with 7 agencies in Spain and the US, and none of them appear on my site, my LinkedIn or my case studies. If we start working together, yours won't either.
I use your tools and processes, and an email address on your domain if needed. I stay off client calls unless you ask me to join.
I never mention your agency or your clients on my site, on LinkedIn or in my case studies. The case studies I publish are anonymised.
I sign an NDA and commit in writing never to contact your clients.
Campaigns, history and billing stay in the client’s account. If we stop working together, there’s nothing to migrate.
Your template, your logo and the format you already use with your clients.
Weekly during the first month, then every two weeks once the account is stable.
There's no account manager or junior between your team and the accounts. I run the campaigns myself and you message me directly.

I reorganised acquisition and remarketing and tested new creative messages. Attributed purchases rose from 63 to 121 and ROAS from 1.83× to 3.12×, with 21.0% more ad spend. Comparison of February 1–28 and March 1–28, 2026: the before-and-after does not establish causation. Attributed value is neither profit nor net revenue.

From one inherited campaign to 13 across three funnel stages
I took over an account running one conversion campaign with a single worn-out creative. I rebuilt it as a full funnel, with static, video, carousel, document and thought-leader formats. I rewrote the lead form and refreshed the creative. Form completion went from 1.6% to 6.1% in three weeks. The most efficient campaign brought leads in at $163, against an account average close to $970.

Total campaign budget
An internship programme with two audiences at once: students on one side, companies on the other. I ran Google Ads to catch searches from recent graduates and LinkedIn Ads to reach HR leads at companies. Each audience got its own landing page. I started on exact match to keep the traffic clean and opened up the winning keywords once they were proven. With target CPA and some device and age exclusions, it closed at 29 conversions at $28 each on a $1,300 budget.

Working with Maria was always very smooth and honestly energizing. She is extremely knowledgeable in paid media, moves fast without losing attention to detail, and always asks the right questions to make the work and performance better.
What I especially appreciate about Maria is how proactive and organized she is. She doesn’t just wait for direction — she comes prepared with ideas, solutions, and recommendations. Everything she works on is very clear and well-structured, and she is also a great communicator, which makes collaboration with her incredibly easy.
Most importantly, Maria genuinely cares about every client and every account she works on, and you can really see that in the quality of her work. She brings together strong paid media knowledge, efficiency, organization, and genuine care for results. I truly enjoyed working with her and would absolutely recommend her to anyone looking for someone they can trust with their paid media.

I propose a tailored price, we sign the NDA and I commit never to contact your clients.
Access to the client’s accounts, the brief and your agency’s report template.
Weekly review of spend and campaigns from the first month.
A report you can forward and a meeting every two weeks once the account is stable.
Only if you want them to. I work with your tools and your templates, with an email address on your domain if needed, and I stay off client calls unless you ask me to join.
