Freelance Social Strategist · Systems & AI · Creator

Jan Eric Langenbach.

Brands hire me when their social needs a direction and boost. There is a launch in six weeks or channel engagement is flat, content stuck in approvals: I can build the system, develop content calendars, create content and ship it. Mars, DAZN, NBA Europe, Toptal, Más+ by Messi. And I built 1.7M followers of my own first, so nothing here is theory.

The worldview

How I think

Culture doesn't wait for the approval round. My job is making brands fast enough to join the conversation. Most brands can make content. Fewer decide what they want to be known for. That decision is the actual job, everything after it is craft.

Ownership.

Social breaks when everyone touches it and nobody owns it. I take the channel, the rhythm and the consequences.

The system.

A good post helps. A working system changes the channel. If it breaks when I leave, I built it wrong.

Taste over volume.

AI can make more. Taste decides what should survive. I shoot, edit and post myself, so I know the difference from the inside.

The room.

Half the job is making the work. The other half is getting it out, past legal, agencies, talent and leadership, without drama.

The toolkit

Skills, with receipts

Anyone can list skills. Tap one and I'll tell you where it earned its place.

AI, used right

AI runs through my daily work: research, outlier analysis, cutdowns, approval workflows. I built an entire AI video system for a US client that their team now runs without me.

But here's the part most people miss. The more feeds fill up with generated sameness, the more human content wins. My job is knowing which half of the work belongs to the machine.

That's the paper. The practice is one scroll down: I built the next section myself, an AI agent running on my own research. Try it ↓

The hook machine

Every video starts with the same question: why would anyone stop scrolling? So I built an answer: my own AI agent, running on a library of 1,000+ hooks I collected, sorted and tested over years. Type your niche, it writes new lines in that taste. Free, no email, no catch.

Tap a hook to copy it. And if you want the other 57 seconds of the video to work too, you know where the contact form is.

Quick answers

Usually mid-engagement, but good projects find room. The fastest way to find out is to ask. Worst case I tell you when I'm free.
Freelance first, usually embedded for a few months at a time. Most of my contracts get extended, some ran for years. For the right team, longer and deeper works too.
Remote first from the Frankfurt / Rhein-Main area, on-site when it matters. For the Más+ launch that meant Buenos Aires, Miami, Toronto, Dublin and London. I show up where the content is.
You have an urgent social problem, a launch, a flat channel, a campaign without a driver. I embed with your team, build the system, make the content, and hand over something that keeps running. Onboarding takes days, not months.
Yes. Shooting, editing, posting, community. I built 1.7M followers with my own hands, that didn't stop when the clients got bigger.
German native, English fluent, plus some Italian. Comfortable working across German, UK and US teams, often all three in one week.
It's on pause. Client work ate the calendar, and I'd rather post nothing than post filler. A revamp is coming. The 1.7M followers and the billion views are real and the archive isn't going anywhere, see for yourself: @german2kballin.
Day rate, depends on scope and length. Ask and I'll give you a straight number, no discovery-call theater.
