Custom software

When your day-to-day runs on spreadsheets and rework, we build the system you're missing, around the way your team already works. You see it running every week, pay only for what you approved, and own all of it.

Let's talk See how it works

What we build

  1. Interface

    Portals, customer areas and SaaS. The screens your team and your customers use every day.

    Service: Portals and SaaS

  2. Business rules

    Internal systems that follow your process, instead of making your team adapt to them.

    Service: Custom software

  3. Integrations

    Your ERP, CRM, payments, spreadsheets and inbox passing data on their own. Nobody types the same thing twice.

    Service: Automation and integrations

  4. Data

    Dashboards with numbers you can trust, without one person stitching spreadsheets together.

    Service: Data and dashboards

  5. Infrastructure

    Cloud, security, backups and privacy, all in accounts under your company name.

    Service: Custom software

AI goes in when a test on your data shows it pays off. When it doesn't, we'll tell you.

Sound familiar?

  1. There's a spreadsheet only one person understands, and nobody touches it while they're on vacation.

  2. Someone on your team types the same thing into two systems, every day.

  3. You bought an off-the-shelf system, and your team keeps working around what it can't do.

  4. To find out where an order stands, someone has to ask around.

  5. The monthly numbers only come out once one person pulls it all together by hand.

If one of these sounds like your company, it's worth a call.

How it works

  1. Call

    You tell us, in your own words, what's giving you trouble. We tell you whether it can be solved and where we'd start.

    30 minutesfree

  2. Diagnostic

    A study with the people who work in the process. You get the process mapped, the scope in writing, what stays out, and the price of each stage. The document is yours.

    1 to 2 weeksfixed price

  3. Build

    One part of the system per stage. We agree with you on what has to work, show it to you at the end, and only bill once you approve.

    stages of 1 to 2 weeks

  4. Live

    Your team starts using it. If a bug shows up in the first 60 days, we fix it for free. After that, there's monthly support if you want it.

What you can count on

You see it working every week

There's a demo every week, and a test link stays open for you to try any day.

You pay for what you approved

A small first payment to get started. The rest only comes after you approve each stage.

The code is yours from day one

Repository, cloud and domain live in accounts under your company name.

You know the price before every stage

No open-ended hours. If the scope changes, you see the new price before any work starts.

You always know who to talk to

You'll hear back within one business day. There's a set call every week, and decisions go in writing.

You can stop at any stage

At the end of any stage, you leave with everything built so far, documented.

Live projects

Six systems in production. We keep client names private, not the problem, the fix or how long it's been running.

  1. 01

    Platform, cloud and docs

    Web platform
    Problem
    A company outside Brazil needed a stable web platform, with its cloud setup and documentation in order.
    Solution
    We built the platform, the cloud as code and the documentation site. It's been live since February 2024, and we still maintain it.
  2. 02

    Chargeback defense

    Education
    Problem
    Every payment dispute meant gathering the evidence by hand.
    Solution
    The system builds the evidence packet, shows where each item came from, and waits for someone to approve it before sending.
  3. 03

    Email triage

    Support
    Problem
    Support emails came in with no category and no priority.
    Solution
    Every email arrives with a category, a priority and a summary. Rules handle what they can, and a stronger model steps in only when needed.
  4. 04

    Data from official sources

    Regulatory
    Problem
    The regulatory information that mattered was spread across government sources.
    Solution
    The data comes out structured with its source cited, a second model checks it, and the team can ask questions of it.
  5. 05

    Document reading

    Lending
    Problem
    Every credit decision depended on someone reading the documents by hand.
    Solution
    The system reads each financial document field by field and shows the confidence and origin of every value.
  6. 06

    Data in one place

    Data
    Problem
    To make decisions, the company had to piece together data spread across several platforms.
    Solution
    A data warehouse brings it all together and feeds the dashboards, pages generated from the data, the ad platforms and AI assistants.

Common questions

How much does it cost?

Cost depends on the size of the problem. We talk numbers in the first call, with no commitment. The diagnostic is paid, has a fixed price, and ends with the price of each stage.

Why not buy an off-the-shelf system?

Often that's the right answer, and we'll tell you when it is. Custom pays off when your process is what sets your company apart, or when several systems don't talk to each other.

Do you know my industry?

That's what the diagnostic is for. We map the process with the people who work in it, and you get the map in writing to check we got it right.

Is my idea protected?

Yes. We sign a non-disclosure agreement before the diagnostic, and the code and data sit in your company accounts from the start.

What about my data and AI?

We handle the data on behalf of your company, under a signed data processing agreement, with a set hosting region and access only to what the work needs.

What does it cost to keep it running?

There's hosting, paid straight to the provider, and monthly support if you want it. Both amounts show up in the diagnostic, before you decide.

If I leave, do I keep my data?

It's already in your accounts. And at the end of any stage you get the documentation to carry on with whoever you choose.

What's it like to work with a studio in Brazil?

Rio is one to two hours ahead of New York, so our working days overlap. Contracts are in English, and we invoice from Brazil in US dollars.
