Scalr Ventures LLC · Marketing, advertising, software

Two products, one personScroll

Two products built end to end. The same person is available for client work.

Run by Marcel Jendrusch. You talk to the person who writes the code and buys the media, so a decision happens in one conversation.

Software development

AI products and the systems underneath them: data pipelines, model calls, billing and the app itself. Built as one piece, so nothing falls between two suppliers.

Proof: Adscalr, 478 API routes and 47 database tables, built alone in about three months

Performance marketing

Media buying on Meta, TikTok and Google: budget structure, creative testing and the call on which ad to stop. I have done exactly this at around 150,000 euros a month.

Proof: roughly 150,000 euros a month of ad spend under my own management

Advertising

Ad creative and the research under it: what competitors are running, the words your buyers actually use, and which format earns attention. It is the same research pipeline that runs inside Adscalr.

Proof: four to six buyer personas per project, each backed by at least three real quotes

How a project runs

Four steps, and you can walk away after the second one.

One email to start

A few sentences about the problem is enough. You get a straight answer on whether it fits, and if it does not I will say so.

Scope on a call

We agree what gets built, what deliberately does not, and in what order. Written down afterwards so both of us can check it later.

You see it running

Progress is a URL you can open. You look at the actual thing every week and say whether it is going the right way.

It stays yours

Code, repositories and ad accounts are in your name from day one. Nothing is locked to a tool that only I can operate.

What I turn down

Saying this early is cheaper for both of us.

Three big projects at once

One person has one calendar. At most two client projects run in parallel, and if both slots are full you get a date instead of being squeezed in.

Renting capacity

Sitting in someone else’s sprint board as an extra pair of hands is not what this is. I take problems that have an outcome attached.

Work without the real numbers

Media buying without access to actual spend and revenue is guessing with your money. If the data cannot be shared, the engagement does not work.

Guaranteed results

Nobody can promise a ranking, a CPA or an interview, so I do not. What I commit to is the work and an honest account of what it did.

Ventures

Both built end to end by one person. Neither is finished, and each card says where it stands.

02 / For performance marketers

Adscalr

View details adscalr.com ↗

AI ad intelligence for performance marketing. It turns competitor intelligence, audience language and performance data into the next ad to ship, and kills the ones that will not work.

Built by one media buyer for his own buying problem
Web platform, currently in private preview

What is next

Named here so nobody has to guess. None of it exists yet.

In preparation

An AI agency brand

The software side gets its own name and its own site, so a client hiring a build is not reading a holding company page. Trademark class and domain are still open.

In preparation

Marcel Jendrusch, personally

Writing about building products and buying media in public, under my own name. It will link back here rather than replace this page.

Under consideration

A performance marketing arm

Managed media as its own offer instead of one service line among three. It depends on whether the first client builds leave room for it.

How this works

This is one person. You talk to whoever writes the code, decisions happen in the same conversation, and nothing gets handed over. The limit is capacity: at most two client projects run at a time.

Tell me what you are building.

One email is enough. Describe the problem in a few sentences and you get a straight answer on whether this is a fit.
