SaaS from scratch
Subscription products with many customers on one platform, pricing plans, recurring billing, an admin panel and onboarding. It's exactly how we build our own products.
Software studio
Custom software, from idea to live product.
We build SaaS products, internal systems, integrations and AI automations. The people you talk to are the people writing the code, and we stay with the project long after launch.
- 2 in-house SaaS products live
- Web, mobile and APIs

What we do
Everything software needs to get off the ground and stay up.
From gathering requirements to running in production. Hire us for the whole project, or just the piece you're missing.
Custom software
Internal tools, portals and ERPs built around the way you work, instead of bending your company to fit an off-the-shelf product.
Large-scale systems
Platforms with many modules, user roles and business rules, like medical records, public-sector management, and operations that juggle inventory and staff.
Integrations and APIs
WhatsApp Business, iFood, Google, payment providers, electronic invoicing and the systems you already use.
Applied AI
Assistants that answer customers and book appointments over WhatsApp, document reading, and LLM-powered automation for repetitive work.
Infra, deploys and support
Servers, domains, HTTPS, backups, monitoring and automated deploys. We look after your system once it's live.
Legacy modernization
Assessment, bottleneck fixes and step-by-step migration, without disrupting the people who rely on the system every day.
Live products
Our own SaaS products, running in production right now.
We build and run products of our own. Client software gets the same care.

Clickable prototype
The key screens, clickable, before any heavy code gets written. This is the cheapest point to change your mind.

FAQ
The questions everyone asks before getting started.
How much does a project cost?
It depends on the scope. After our first conversation we send a proposal with a fixed scope, timeline and price for each phase, or a monthly fee when you need a dedicated team. That first conversation is free.
How long does it take?
An MVP usually takes 6 to 12 weeks. Larger systems ship in stages, with something working every two weeks.
Can you take over a system that already exists?
Yes. We start by assessing the code and infrastructure, then propose what to fix, modernize or rewrite, in order of priority.
Who owns the code?
On custom projects, the code and all access belong to the client, as set out in the contract. We hand over the repository, documentation and infrastructure access.
What happens after launch?
We offer support plans that cover hosting, backups, monitoring, bug fixes and new features. You're never left alone with the system.
Do you work with companies anywhere?
Yes. We work remotely, with video calls and access to the staging environments throughout the project.
Have a system in mind, or one that needs rescuing?
A 30-minute call is all it takes to see whether we're a good fit.
