WetterOnline: creator marketing without a classic sale

The short version

An ad-funded weather app earns nothing at the point of purchase but from years of use. This case shows how creator marketing works there too — and it states openly the target that was missed along the way.

  • Factor of 5 to 10

    above the sub-EUR-1 CPI stretch target — and continued regardless

Results & evidence

  • ~30m

    monthly active users worldwide

  • nearly 30

    countries

  • under 4 weeks

    to the first ten or so partnerships

  • over 90%

    share of revenue that is ad-funded

  • 7 months

    fastest payback on a user, in Germany

Problem

Marketing ran almost entirely at the very bottom of the funnel, through App Store search. Further growth meant moving up the funnel.

THE BENEFIT DOES NOT SHOW IN GENERAL, ONLY IN A SPECIFIC CASE.

The insight

A weather app is hard to sell to the general public — you can, after all, just look out of the window. Anyone who fishes, forages for mushrooms or runs gets the value without a word of explanation.

The starting point

With no moment of purchase, a user's value is not a single order but years of usage. That is hard to model, not least because there is no login and device changes distort attribution. Monetisation per session sits at a fraction of a cent. A paid user therefore takes anywhere between around seven months in Germany and over two years in new markets to pay back.

The performance marketing so far, across Google and Meta, ran almost entirely at the very bottom of the funnel: people search the App Store for weather and download whatever ranks best. But telling new users to download a weather app now works poorly, because most of them do not know the concrete everyday benefit at all.

On top of that: in a settled summer, interest in the weather drops noticeably, and when demand is low Google automatically serves more expensive formats. What was needed was a channel that creates context rather than sales — and that scales internationally.

About WetterOnline

WetterOnline is based in Bonn and turns 30 this year or next. The company runs Germany's largest weather app, complete with rain radar, alongside paid pro apps, and operates in nearly 30 countries with a good 30 million monthly active users worldwide across Android and iOS. Over 90 percent of the business model is ad-funded; the share from subscriptions is negligible.

Revenue is in the mid eight figures.

Our approach

We built a systematic creator programme for the first time — one explicitly aimed at context rather than at driving sales. The core: very deep niche creators rather than big-reach names, showing credibly in which concrete situation a weather app makes the difference.

WetterOnline had barely worked with external partners before, so the value lay above all in speed and experience: the first partnerships were in place within days, which served internally as proof the channel was doable. Alongside new users, the programme serves a second purpose: re-engaging people who installed the app but rarely open it.

Context rather than a prompt

Telling new users to download a weather app now works poorly. What is needed is a situation in which the weather shapes a decision. Niche creators supply exactly those situations.

The channel delivers more than installs

Every partnership produces language material. Terms from the niche end up in the brand's own ads. Creator marketing thereby becomes a tool for understanding the audience in the first place.

An honest assessment rather than a nice number

In this business model, direct value per install is not a usable measure on its own. Delayed organic installs and the reinforcement of existing users systematically fall out of it. That belongs stated, not calculated away.

Approach
How we went about it

Internally, researching and approaching creators would have tied up resources that cannot simply be freed up. The maths behind it: you contact around 300 creators, about 80 reply, from which around 20 partnerships come about, at roughly five minutes per approach plus research. With us, the first commitments were in place within days.

I am not going after first-order profit; I am going after owning a market over the long term.
