What We Do
Join the conversations that convert.
Advantage is a results-driven Twitter (X) Ads agency for founder-led companies of two to fifteen people in the Netherlands and across the EU. With millions in profitable ad revenue generated for fast-growing founder brands, we know what it takes to turn ad spend into scalable growth.
We take a performance-focused approach, ensuring every campaign is optimized for conversions and efficiency. By combining precise audience segmentation, creative testing, and budget optimization, we tailor strategies that drive measurable results while keeping costs under control.
Because X is built on live conversation, we build campaigns that attach your brand to the topics and communities your customers already follow. Our expertise in interest and follower targeting, promoted posts, and takeover formats ensures your message lands in context, not in isolation.
But targeting alone isn’t enough. Successful X advertising also depends on compelling ad creatives that capture attention and drive conversions. We design, test, and refine high-performing visuals and copy to maximize engagement and return on ad spend. Whether you’re launching your first campaign or looking to scale, our strategies are built to help founder-led brands achieve sustainable, long-term growth on X.

Our Approach
X Advertising Agency
Audience Targeting
We build precise audience segments from your customer data, site behavior, and lookalike modeling, so every euro of spend reaches people who resemble your best clients.
Interest stacks, custom audiences, and exclusion lists are refined continuously as the campaign learns.
Creative Content
Scroll-stopping ad creative built around your founder’s voice: short video hooks, carousels, and statics designed for the feed, not adapted to it.
Every concept ships in multiple variants so we can test hooks, angles, and formats against each other.
Strategic Planning
A full-funnel campaign architecture mapped to your goals and budget: cold prospecting, warm retargeting, and conversion campaigns that hand off to each other cleanly.
Budgets, bid strategies, and scaling thresholds are agreed up front so growth never outruns profitability.
Data Analytics
X Pixel and Conversion API tracking wired into your website, so every decision is based on revenue data, not platform vanity metrics.
Monthly reporting ties spend to pipeline: which ad, which audience, which euro of return.
Why choose Advantage?
We drive ROI with targeted, high-performing Twitter (X) Ads.
We measure our work by the revenue it creates, not the hours we bill. When your campaigns grow profitably, we keep the engagement; when they do not, we have a problem to fix.
That alignment shapes everything: budgets we recommend, tests we prioritize, and the honesty of our reporting.
Every founder-led brand hits a different bottleneck: weak creative, wrong audiences, leaky landing pages. We diagnose what is actually holding your funnel back before we spend a euro.
The campaign structure is then built around that diagnosis, not around a template we reuse for every client.
X’s platform changes weekly. New formats, placements, and bidding strategies appear constantly, and the advantage goes to whoever tests them first.
We run structured experiments on a slice of budget, so your account learns faster than your competitors’.
Scroll-stopping creative does not come from stock footage and generic hooks. It comes from the specific, opinionated voice of the person who built the company.
We turn that voice into short video hooks, carousels, and statics designed for the feed, not adapted to it.
Every euro of spend is tracked to the campaign, creative, and audience that produced it, wired through the X Pixel and Conversion API.
Monthly reporting ties spend to pipeline: which ad, which audience, which euro of return. No vanity metrics.
Many agencies rely on guesswork, but at Advantage every campaign is carefully customized to maximize efficiency, revenue, and return on ad spend while minimizing waste.
We scale what works and kill what does not, keeping your cost per acquisition trending down as budgets grow.
Our incentives are aligned with yours.
We measure our work by the revenue it creates, not the hours we bill. When your campaigns grow profitably, we keep the engagement; when they do not, we have a problem to fix.
That alignment shapes everything: budgets we recommend, tests we prioritize, and the honesty of our reporting.

X Advertising FAQs
X is where conversations happen first: news, niche communities, and industry debate. For founder-led brands it offers underpriced attention in specific communities and a direct line to audiences other platforms bury.
Before we spend a euro, we look at your offer, margins, and audience to confirm the economics work. If we do not believe X ads can be profitable for your brand, we will tell you, and suggest a better channel instead.
Your budget is up to you. Most of our clients start between €1,500 and €5,000 per month in ad spend, plus our management fee. We agree budgets and scaling thresholds up front, and you can adjust at any time, there are no long-term spend commitments.
You will see it in the numbers, not in our opinion. Every month you get a report that ties spend to results: cost per lead, return on ad spend, and revenue attributed to each campaign. If a campaign is not working, the report shows that too, and what we are changing.
Absolutely. The ad accounts are yours and you keep full access. Some founders want weekly involvement, others a monthly summary, we adapt to how hands-on you want to be.
Testing, not guessing. Every campaign launches with multiple hooks, creatives, and audiences competing against each other. We keep what the data proves and cut what it does not, then repeat, every week.
Great, that gives us data to work with. We start with a full audit of your existing campaigns, pixel setup, and audiences, then rebuild what underperforms rather than starting from zero. Historical data usually shortens the path to profitability.
It depends on where your customers spend their time. X excels at community and conversation, and many brands pair it with Meta or Google to convert the attention it earns. We run those channels too and will tell you honestly what mix fits your funnel.
Yes. X ads work best as part of a system: positioning, content, landing pages, and follow-up automation. As a full go-to-market agency for founder-led companies, we can take on as much of that system as you need.
Because our model is built for companies like yours. We work exclusively with founder-led teams of two to fifteen people, we measure ourselves on revenue rather than impressions, and you work directly with senior people, not an account manager reading from a script.
