Tallisto: brand identity for an

Tallisto: brand identity for an AI accounting SaaS that closes the monthly books. A concept project.

The mark comes from a medieval tally stick. In 12th-century England a debt was recorded by cutting notches into a stick, then splitting it in two. Each side kept a half, and if the halves matched, the books agreed.

That is what Tallisto's agent does. It matches every bank line to the ledger, and a person signs it off. So the logo is two sticks, the stock and the foil, carrying the same two cuts.

One rule holds the system together: Lamp Green only appears where a person has approved the agent's work. It's never used on buttons or as decoration.

The rest is calm on purpose. Ink and Paper as the base, Instrument Sans for words, JetBrains Mono for figures, and a "ledger of tallies" pattern that never sits behind text. You can see it here on the website, the close dashboard, a mobile sign-off screen, business cards, an office wall and an Underground poster.

Would a finance team trust a tool more if its logo had a reason behind it, or do they only care about the numbers?
