Orbbe Labs · Made in Brazil

Agents that do the expert work. You keep the final say.

We build focused apps for small businesses and small teams. In each one an agent takes on specialist work, from aerodynamics to the monthly books, and shows you the numbers behind every answer.

Money for small business owners

Mudda

Your money and your company’s, in one place.

For people who own a small company, and for couples who run one together. Mudda connects personal and business accounts through Open Finance and shows the whole month on one screen: what came in, where it went and what is left.

  • Personal and company side by side

    Your CPF and your CNPJ in one view, instead of two apps and a spreadsheet.

  • Sees, never moves

    Read only Open Finance access. Mudda cannot move a single real.

  • Asks instead of guessing

    A transfer with no recipient never becomes a guess. Your answer decides.

Aircraft design by conversation

Maiden

Say what your plane has to do. Maiden does the aerodynamics.

An agent interviews you, turns each wish into a requirement with a number, then changes the design and runs aerodynamic solvers until it passes. For RC builders, drone teams and AeroDesign students.

  • Checked by solvers

    Stability, stall order, trim and controls come from vortex and panel methods, not rules of thumb.

  • Every number has a source

    Each value is derived or computed by a solver, or refused with the reason.

  • Free to start

    New accounts get 500 credits. Free for SAE BRASIL AeroDesign 2026 students and teachers.

What we are building next

Line drawing: a monthly calendar with a few days checked off and a checklist beside it.

Fecha

In development

For small accounting firms

Close every client’s month without chasing anyone.

A board of what each client still owes the firm this month, and an assistant on WhatsApp and email who asks for it, files what arrives and answers the questions clients repeat.

Tenon

In development

CAD for agents

An agent writes the model. Tenon builds the exact part.

Parts are short programs an agent edits. Tenon rebuilds them in milliseconds, reports what it built in numbers and exports STEP for the shop.

How we build

Three rules every product follows

  1. 01

    An agent takes the specialist job

    Aerodynamics, geometry, the monthly follow up with clients: the part of the work that needs an expert is done by an agent that knows the field.

  2. 02

    Numbers, not impressions

    Answers come with the data and the method behind them. When something is missing, the product asks instead of guessing.

  3. 03

    You make the call

    Agents propose, check and report. The person who knows the business decides what happens next.
