Olaari means a season of plenty

In Maasai, olaari speaks of the rains that turn hard ground into harvest. That is the work we do for brands.

We opened in Dar es Salaam in 2011. Fifteen years here taught us how Tanzanians watch, listen, scroll and buy.

Olaari was born from Saracen. Today it is a full-service agency, with strategy, creative, media, digital, PR and events under one roof.

We exist to give every brand we serve its season of plenty: growth you can feel in the numbers, in the market, and in the people who choose you.

Kila shilingi irudi kama ukuaji.

Every shilling should come back as growth.

Five reasons brands grow with Olaari

  • The people in the room know the market

    The people in your meetings are the ones who know your market, its media and its language.

  • One team, one lead

    Strategy, creative, media, digital, PR and events plan together from day one, and a single senior lead is accountable from brief to report.

  • Rooted in media

    Fifteen years planning and buying media, and checking every run.

  • More hands when needed

    Extra specialists join the same pod when the brief asks.

  • Return you can see

    We track every shilling to the business result it delivered.

April Fools turned a bedroom myth into a national joke, then the truthDKT International · Kiss
Kiss April Fools post in Swahili beside a model holding an oversized Kiss pack.

The truth we found. Many men skip condoms with one line: “I’m too big.” It is a myth built on ego and bravado, and it keeps them unprotected.

The idea we made. On April Fools, Kiss “launched” an absurd XXXL edition, let the internet play along, then revealed the truth: condoms fit every size.
