Then this mentorship is for you.
I will help you learn to find and tell stories with data. Together we will pick a project to work on for 8 weeks. In this time, we will build the skills of your choice. Be it basic data analysis, programming, or data communication. By working towards an actual story from start to finish, you will learn to use these skills to work seamlessly with any other aspects of research and reporting.
Regular online meetings to review your progress, tackle challenges, and refine your work. Daily support via Discord.
Personalized 8-week program covering topics chosen to accelerate your growth as a data storyteller.
Join a curated Discord community for extra resources, peer feedback, and networking with other data professionals.
What is out there and what is not and what can you make yourself. Learn to navigate government databases, freedom of information requests, and public records. Discover when to scrape data from websites, conduct surveys, or create datasets through observation and research.
Combine your qualitative and quantitative skills. Master the art of finding patterns in numbers while maintaining the human stories behind the data. Learn to use data as evidence to support your reporting and develop hypotheses that guide your investigation.

"When Ada was assigned to mentor my team on a recent cross-border investigation, I had little grasp of what data journalism really entailed — let alone how it could become central to my reporting. Under her guidance, I quickly learned the essentials, from the value of “tidy data” to uncovering stories in pivot tables. More importantly, I came to see that data journalism is not about decorating articles with charts, but a holistic approach to unearthing truths and telling impactful stories. Ada was the ideal mentor — always available, responsive to our needs and deeply attuned to the dynamics of our project. She moulded our investigation more than anyone else, and has fundamentally reshaped my long-term approach to journalism."

"What is it you want to do?" From this starting point, conversations with Adriana are about more than just code and technical skills but about taking a systematic approach, thinking through the steps to reach a solution, regardless of your preferred coding language or whether you're a fan of Excel or Google Sheets. Whether it's solving a specific task or building entire data pipelines or databases, basic or complex, it's always enjoyable to work through it together. In mentoring sessions, Adriana shares her vast experience of all matters data and visualisations, and always finds the time to send resources and ideas to accompany one's research. Adriana's advice has stayed with me to this day, five years after first meeting her as a teacher in a data journalism class, as have the jokes we shared."

Data Journalist & Educator
Hi! I'm Ada. I am a freelance data & investigative journalist and teacher. Over more than 10 years, I made a lot of stories with small and big datasets and I am here to share what I learned along the way.
From the start of my career, I’ve loved helping other journalists get comfortable with data, brecause I believe these skills should be for everyone. Over the years, I’ve given countless lectures, taught at conferences like Dataharvest and NICAR, given guest lectures in the Master’s program in Gothenburg, and mentored journalists 1:1 through programs like IJ4EU.
I founded Data Frosch by accident, because I bought a frog hat last winter. It's a fun way to put myself out there and help others find me.
