Sparkasse turned loan doubt into the NOT-SURE song and a personalised hit machine

Show loan customers the bank knows how they feel, in a campaign deliberately unlike the category's usual hard sell.

An absurdist earworm that lists relatable reasons for taking out a loan, then answers each with a sung 'not sure' — until every path leads to the savings bank

A music video directed by Element E's Bernd Faass, with the singing voice of Berlin artist Ludwig Berndl, rolled out nationwide on TV and social; an online 'hit machine' let people create personalised NOT-SURE songs for occasions like Mother's Day.

A campaign of up to 20 original songs plus the personalised hit machine; no results figures reported.

In April 2018 German savings bank Sparkasse and agency Jung von Matt/SPREE launched the NOT-SURE song, a music-video campaign built on the insight that people often aren't sure whether they can afford a loan for large purchases — the head says no, the gut says sure, why not.

The song lists relatable reasons for taking out a loan and then rejects each with its NOT-SURE wit, until all decisions lead to the savings bank. Sparkasse head of marketing Silke Lehm said the point was to show the bank knows how its clients feel; Jung von Matt/SPREE CCO Till Eckel said it was deliberately different from the hard-sell advertising the category is used to.

Directed by Element E's Bernd Faass and sung by Berlin-based artist Ludwig Berndl, the video rolled out nationwide on TV and social media. The campaign grew to up to 20 original songs, and an online 'hit machine' let people create personalised NOT-SURE songs for special occasions like Mother's Day or for friends. No results figures are reported.

Every loan ad promises confidence; singing the customer's actual doubt makes Sparkasse the only bank sounding human.

A repeated two-word refrain is engineered to stick — the campaign's media plan leans on the earworm carrying itself.

The hit machine turns viewers into producers, generating personalised songs that spread the campaign for them.

Twenty songs give the platform longevity across occasions and placements instead of one film's single flight.

Doubt is the honest emotion of your category — sing it, and the brand becomes the answer without a hard sell.

The campaign rolled out nationwide on TV and social from April 2018, expanding to up to 20 original songs and the online hit machine. No results figures are reported.
