Looking for a paid media agency usually ends the same way: a junior account manager, a monthly platform report and metrics that never show up in your P&L. Nash Marketing Labs exists to do the opposite. We are small on purpose: every account is run by someone with more than a decade of experience optimising real ad spend. We are based in Spain and work with clients in English as well as Spanish.
Before talking to anyone you can put numbers on your own case: our free tools calculate your account's ceiling based on your business model, right in your browser.
What exactly you are hiring
You hire the Nash Paid Lab, our Digital Ads service: strategy, execution and daily optimisation of your campaigns on Google Ads, Meta Ads, TikTok Ads and LinkedIn Ads. And you get the rest of our specialist Labs as internal infrastructure, at no extra cost:
- Nash Tracking Lab: server-side tracking, advanced GA4, Consent Mode and CAPI. If measurement is broken, everything else is noise.
- Nash BI Lab: your platform, analytics and sales data unified in our own pipeline, with automatic daily reporting.
- Nash Classification Lab: catalogue classification by profitability and scaling potential (SKUSCALE).
- Nash Generative Lab and Nash Automation Lab: AI-assisted creative production and workflow automation between ad platforms and CRM.
How we work: performance engineering
Our performance engineering methodology has five steps and an order we don't negotiate: Model the business (margins, goals, constraints), Calibrate measurement, Visualise the data where decisions are made, Optimise against business metrics, and only then Scale. Most accounts we audit try to scale without going through the four previous steps. That is why they burn budget.
Who we work with
We don't do everything for everyone. The profiles where we add the most value:
- Large-catalogue ecommerce (distribution, 10,000+ products) where every SKU carries a different margin. Paid media for ecommerce.
- Own-brand ecommerce that wants to scale revenue without burning the brand.
- B2B with a long sales cycle, where a cheap CPL is usually a lie and lead quality is what matters. B2B paid media.
- Info products and B2C lead gen: from one-off launches to an evergreen system.
Paid media platforms we manage
We don't recommend channels out of habit. The mix is decided with your business data:
- Google Ads: Search, Shopping, Performance Max and YouTube. Capturing existing demand and protecting your brand. Where the most money is wasted while looking efficient.
- Meta Ads: Facebook and Instagram. Demand generation with data-driven creative, server-side CAPI and a structure that separates prospecting from remarketing.
- TikTok Ads: for brands with a visual product and an average order value compatible with the platform's CPA. Not for everyone, and we will tell you if it isn't for you.
- LinkedIn Ads: the most expensive channel per click and often the cheapest per SQL in high-ticket B2B. Targeting by job title, industry and company size.
Results for our paid media clients
We don't promise results that depend on variables we don't control. We show real numbers from real clients and how they were achieved:
- 8–15x ROAS sustained in large-catalogue ecommerce accounts, measured against margin (not against gross platform revenue).
- -83% CPL in B2B campaigns without sacrificing lead quality: cost per SQL dropped because the CRM-to-platform loop stopped optimising blind.
- €18M+ managed that has returned €220M+ in revenue to our clients: more than €10 for every euro invested, aggregated since 2015.
- Accounts are run by the people who make the decisions. No account manager layer between your business and whoever touches the campaigns.
The detail behind these figures is available for profiles that fit. The viability audit (free, no strings attached) is the first step to find out whether your case has similar potential.
How the operation is set up
Few accounts per manager, on purpose: whoever decides on your spend has time to look at it every day. Reporting comes from our own data pipeline, reconciled with your actual sales, not from the platform dashboard. Every change in the account is documented with the reason and the number behind it. And our commitment is on what we control: structure, measurement, bidding criteria and speed of decision.
Frequently asked questions
What minimum ad spend do I need to work with you?
We work with accounts from tens of thousands of euros a month up to several million a year. Rather than a rigid minimum, we look for spend that lets the account learn fast: if the budget doesn't generate enough signal to optimise, we will tell you in the audit.
Do you only manage Google and Meta?
Google Ads, Meta Ads, TikTok Ads and LinkedIn Ads. The mix depends on your business: in B2B the weight usually sits on Google + LinkedIn; in ecommerce, on Google Shopping + Meta.
How are you different from other performance marketing agencies?
We measure in business terms, not platform terms, and we bring the infrastructure: our own data pipeline, catalogue classification by profitability and automation. Most agencies report platform ROAS; we work against margin and P&L.
How do I get started?
With the viability audit: you tell us about your case, we review your accounts and come back with what to scale, what to keep and what to pause. Free, no strings attached, and with that result we decide together whether a management proposal makes sense.
Is your paid media a profitable system or just a pile of campaigns?
Tell us about your case and we return an actionable diagnostic: what to scale, what to keep and what to pause. Free, no strings attached.
