The LetsData Take

One of us, sharing what we’re working on, what keeps us up at night, and what we’ve learned.

From past letters:

Ksenia’s take on the economy of narrative defence

Every other Thursday, a different person from our leadership team writes to you personally.

What we write about

Each letter comes from one person and reads the way they would write to a colleague they trust.

What I’m working on. The problem on my desk right now, and why it matters beyond our company.

What keeps me up at night. The challenge I haven’t solved yet, and how I’m thinking about it.

What I’ve learned. Something useful from the work: what worked, what didn’t, and what I’d do differently.

Who’s writing

Every letter comes from a different person on our leadership team.
