The company

A&A Financial Consulting is a financial consulting firm that brings finance leadership to owner-run U.S. businesses. We help owners plan budgets, control costs, understand their margins and manage working capital, and we train their teams to keep those routines after the engagement.

The firm is led by Natalia Arantes, a CFO with more than 15 years in finance, and Lucas Rosa de Arantes, who leads sales and brings an IT, cloud and security background. Together they built Mentor IA, a cash-flow application that gives clients a live, explained picture of their cash, so consulting and technology work from the same numbers.

Our mission

Help small businesses make financial decisions with the clarity of a company that has its own CFO.

Small employers carry the same cost pressure and cash-flow swings as larger firms, with far less finance support. We exist to close that gap.

Our objectives

Make CFO-level finance accessible

Bring the planning, control and analysis that larger companies take for granted within reach of owner-run businesses.

Build financial capability

Train owners and teams to read their own numbers and run financial routines without depending on us.

Use technology to scale access

Mentor IA gives every client a live, explained view of cash, so good financial management does not depend on a large budget.

How we work

Your numbers first

Every recommendation starts from your own data.

Build capability

The goal is a team that runs the routines without us.

Plain language

Reports an owner can read and act on.

Technology where it helps

Mentor IA supports the work and does not replace judgment.
