Have you ever felt like you're studying data diligently on your own, but still relying on 'intuition' when it comes to actual work? You read books, take courses, and try things out in practice, but often it's hard to grasp what exactly it means to "work based on data."

Datarian has prepared a seminar to resolve that frustration.
In the November seminar, 17-year veteran product designer Lee Mi-jin (Ranran) will share 'How to work data-driven without data analysts' based on her direct experience at 7 small startups.

If you're curious about the vivid real-world cases and know-how that couldn't be fully covered in the Brunch Book award-winning work "UX Emerged at the End of Data Struggles", don't miss Datarian's November seminar "Data-Driven Design Without Data Analysts".

Hello planners and marketers,
Has anyone seen the outdoor advertisement for Speak that covered Gangnam Station earlier this year?

It is not easy for a startup with a limited budget to plan and confirm outdoor advertising.

I would like to share a blog post written by 'Jung Du-hyeon', a Speak Branding Marketer, about the difficult process of planning, confirming, and executing outdoor advertising.

I think there are many people who are worried about the promotional plans for the year-end and New Year holidays.
I recommend that you read Duhyun's blog post and use it as a reference to learn how to persuade your CEO and team members.
