German media firm Weischer has taken a stake in Lüneburg-based AI market-research startup Erason, betting that smarter data can cut ‘Streuverlust’ — the ad waste that means much advertising never reaches the right people.
The deal
Weischer, one of Germany's larger owner-run media companies, has taken a stake in Erason, an AI-driven market-research startup based in Lüneburg. Announced in mid-August 2026, the tie-up is framed as a bid to deepen Weischer's data capability, with Erason co-founder and chief executive Niklas Mrutzek and Weischer boss Udo Schendel fronting it. Financial terms were not disclosed.
Erason's pitch is simple: use AI-powered market research to work out who an ad should actually reach, and cut the spend that lands in front of the wrong people.
Why ‘Streuverlust’ is the target
‘Streuverlust’ — literally ‘scatter loss’ — is the German industry's word for ad waste, and Weischer's argument is blunt: a large share of advertising in Germany simply misses its intended audience. It is a problem hiding in plain sight in most media plans.
The numbers elsewhere are sobering. The US Association of National Advertisers has found that only around 36% of a programmatic dollar reaches the consumer once the ‘cost waterfall’ of intermediaries and low-quality inventory is stripped out. Even if Germany's mix differs, the direction of travel is the same: too much money, too little precision.
Data as the new media currency
This is why a media-sales business is buying into a research startup rather than more billboards. In an addressable, AI-mediated market, the edge is no longer just owning inventory — it is knowing, with confidence, which audience each impression should serve. Weischer is effectively bolting a targeting brain onto its media.
It fits a wider 2026 pattern in Germany, where players from retailers to broadcasters are racing to turn first-party data and AI into a media advantage rather than a back-office function.
What it means for advertisers
Our read: if you buy media in Germany, expect your partners to start selling ‘less waste’ as hard as they sell reach — and hold them to it. Ask for the audience definition behind a plan, the data source and how waste will be measured, not just the gross impressions.
The opportunity for smaller advertisers is real. Capabilities that were once the preserve of big-budget programmatic teams are being packaged into media offers; the brands that ask sharp targeting questions will get more from the same budget.

Every media plan has a silent line item nobody prints: waste. Weischer buying into an AI research firm is a bet that whoever measures and shrinks that line wins the next decade of German media. Smart advertisers should demand the same rigour — ask who your money is really reaching. — Daniel Nikolla, Founder of Merx Marketing — Daniel Nikolla, Founder of Merx Marketing Ltd and Marketing Minute
In an AI-driven media market, cutting waste is the new growth — the winning question is no longer ‘how many did we reach?’ but ‘how many were the right ones?’
