Interrupting without annoying
Your ideal customer scrolls past. We make them stop.
-
Ads that get scrolled past
Your campaigns reach people, but nothing in them makes anyone stop.
-
Targeting that is too broad
You pay for reach among people who were never going to buy.
-
Creative that does not fit the platform
What works on LinkedIn does not work on Meta, and the other way around.
-
No line from spend to result
You can see the reach. You cannot see the revenue.
Reach the people who actually matter
Social advertising is the art of interrupting without annoying: the right message, to the right person, at the right moment, in a format that belongs on the platform it appears on.
It also lets you reach people by who they are rather than by what they happened to search for, which is the one thing search advertising cannot do. We put the budget on the channels where your audience already is.
Creative made for the platform it runs on
The same advertisement rarely works twice. A LinkedIn feed and a Meta story ask for a different length, a different tone and a different first second.
So we produce per platform instead of resizing: creative that fits your brand and the audience it is aimed at, where every ad has one job and one audience.
Your social advertising with JKC
- Campaigns built on a single objective
- Reach among the people who fit
- Creative made for each platform
- A clear line from spend to lead
The funnel does not end at the click
Most social budgets are spent entirely on people who have never heard of you, which is the most expensive audience there is.
We build the rest of it too: retargeting on the people who visited but did not act, and campaigns aimed at the audience that already knows you, where the cost per lead is a fraction of the first click.
Testing is the campaign, not a phase of it
On social, the creative wears out. An advertisement that performed for three weeks is not a permanent asset, it is a result with an expiry date.
So testing runs continuously: audiences, formats and hooks against each other, with budget moving to whatever is currently working rather than to whatever worked at the start.
Find out which channel deserves your budget
Better social advertising starts with knowing which platform your audience is actually reachable on.

FAQ
We often get these questions
It depends on what you need. The Hybrid Approach starts at EUR 4,500 and builds on proven building blocks; a Fully Custom project is quoted once we know your goals and what has to connect to what.
Either way you get a fixed project fee agreed before we start, so there is no invoice afterwards that you did not see coming. You pay for the thinking that goes into an hour, not for the hour.
We work with fixed project fees. All terms are set out in the roadmap you sign off on before the first line is written, so you know what lands on the invoice and when.
No hourly surprises afterwards, and nothing billed that you did not approve.
Every project starts with a session about your goals, your market and where growth is stuck today, not with a standard intake form. From there we write a roadmap: what we build, in what order, and what it has to deliver.
You get a decision moment at every step, so there is never a version you see for the first time when it is already finished.
Most agencies deliver a website. We take responsibility for what it has to achieve. Strategy, design, development and marketing sit under one roof, so nothing gets lost between three suppliers who each blame the other two.
We use AI to work faster, not to replace the people doing the thinking. What you end up with is a foundation that keeps working after launch and a team that stays involved.
Yes. We build complete digital platforms, but you can also bring us in for one part: brand strategy, design, a specific integration, or the marketing around a site someone else built.
We would rather do one thing that moves your result than everything at once.
