Nalepa Labs™ · Florida

Built by accountants who got tired of waiting for software to catch up.

We make AI tools for the back office of small accounting firms. TransactionFlow, our standalone AI-native accounting platform, and Open Mind Ledger are both live today. More to come.

01What we do

Nalepa Labs™ builds practical AI for the workflows accountants actually run — bookkeeping, transaction categorization, small-business tax. The premise is simple. An accounting firm that writes its own software ships tools the rest of the industry will eventually copy.

02Products

Two products, both live. Built for the same audience — small accounting practices — from different angles.

TransactionFlow

Open Mind Family ProductLive

A standalone, full-stack accounting platform with AI built in — bank feeds and statements in, books categorized and posted under your control, month closed with the evidence attached. $65 per month per client, everything included. Live at omtransactionflow.com with a seven-day free trial; get in touch if you'd like to talk through fit first.

Open Mind Ledger

Open Mind Family ProductLive

A complementary product to TransactionFlow, built for the same audience from a different angle. Now live and available at openmindledger.com.

Bringing AI into your firm? We've done it inside ours.

We help accounting practices look through their processes and decide where AI belongs — and where it doesn't. Deterministic where the numbers are, secured by default, every figure an agent pulls traceable to its source — and built so your own team can extend it. It is the discipline TransactionFlow was built on.
