CECILIA
ROOS

Hi, I’m Cecilia. This is my digital garden; a collection of evolving things that I'm building, reading, and enjoying.

A bit about me

For the last 8 years I was focused on building products and leading product teams at EF Hello.

Earlier this year I started to transition into AI Safety. I quickly noticed there are relatively few people like me in this space: product background, mid-career, commercial experience. This has led me to start my own thing, Cherry Tree, learn more below. I’m also spreading the word about how people with my skills and experience can make a positive contribution to AI Safety. (Ask me about how!)

I’m known for my energy, my laugh, and being a very good listener (unless you’re telling me how gross you think tea is).

Often found automating a repetitive task, reading something beautifully written, devising another silly game, or thoughtfully picking a glass of wine to suit my mood and the sky outside.

I’m also pretty obsessed with tulips. I’ve tried to keep that subtle.

Work

Cherry Tree

Co-founder · Now

My co-founder and I are building Cherry Tree to help people understand the accuracy and context of information they encounter online, think better about that information, and ultimately make better decisions. We do this by showing you what primary sources say and putting the best available information in context, so you can make up your own mind.

We’re testing early versions now. If you’d like to be a tester, I’d love to hear from you.

EF Hello

Head of Product · 2018–2026

I joined pre-launch at the early stages of designing EF Hello, and went on to lead the team of ten as we grew from zero to more than five million users. Very proud and lucky to have worked with some fantastically talented people, garnered a loving and loyal userbase, and been recognised for the quality of what we created.

My recommendations

Comparative tastings

I organise comparative tastings with a grading matrix. Opinion is divided on whether this is Type 1 or Type 2 fun.
