# I built the study app I wish my kids had.

I'm Elina. Mom of two, designer, and someone who went too deep into learning science and couldn't come back out. I spent years building edtech products for other companies before I built one for myself.

Lexie exists because the research on how memory works is clear, and almost nobody in edtech is following it.

## Why Lexie exists

I wanted my kids to be independent learners with the right tools and techniques. The tools didn't exist in a form that actually worked. So I built one.

## What I believe about learning

Retrieval practice, spaced repetition, desirable difficulty. The research is decades old and remarkably clear. Struggle is the mechanism, not a side effect. Most edtech skips this because engagement is easier to measure than learning.

## How I build

Solo founder. I design, I code, I ship. No handoffs, no meetings, no waiting. 16 years at the intersection of design and engineering, and I work faster alone than I ever did in a team.

## Background

Principal designer at Otava Learning, one of Finland's largest edtech companies. Before that, City of Helsinki's digital services, agency work, clients ranging from Nokia to the city itself.

## Previously

I've spoken at [Yle's AI demo](https://areena.yle.fi/1-68148213) on design and the future of learning, and written about AI and education for Helsingin Sanomat.
