About

We built the thing we wished existed.

Henri built Kirje after getting frustrated with every Estonian bookkeeping tool on the market.

The story

We started in 2025. The first idea: if AI can read an invoice, why can't it do bookkeeping? Today we post lines straight to e-Financials for founders and accountants tired enough to try something new.

What we believe

Augment, never replace

We do NOT replace arvio.ee, Synx, or e-Financials. We work alongside them.

Encrypt always

Every API key, every text we hold — encrypted at rest, decrypted only in memory.

EU by default

Data in the EU. Models in the EU when possible. Logs and audits in the EU.

Kirje assists, doesn't rule

Your accountant without Kirje is just your accountant. Kirje is what lets them take on 50 OÜs.
