When Excel, WhatsApp or the system you have are no longer enough.

Custom software and integrations with enterprise engineering

We connect your ERP, CRM and the platforms you already use (SAP, Salesforce and more), build internal systems and SaaS from scratch, and modernize what got old. Prior technical analysis and milestone-based pricing.

What we do

Software that solves your operation

We design, integrate and develop software with the engineering of large-scale companies.

Custom development

Web apps, internal dashboards, APIs and automations. We build exactly what your operation needs, with a modern stack and enterprise rigor.

Milestone-based pricing

Integrations

We connect SAP, Salesforce, your ERP, CRM, payment gateways and any API. So your systems stop being isolated and talk to each other in real time.

SaaS and modernization

A multi-tenant SaaS product from scratch, or the rescue of the internal system that got old. We migrate without stopping your operation. Real case: Sodapp.

Your systems, finally connected

Artificial intelligence

We also integrate AI to process your data

Classify and extract data from documents, automate customer support, summarize and analyze text. We pick the model for the case: Claude, ChatGPT, Grok, Llama or Gemini.

Project under NDA

Custom platform for a services company. Under construction, launch planned for 2026. We can't share details yet.

Letter of intent
SaaS and custom development

We don't quote from a template. We talk first.

For projects that go beyond a website (SaaS, internal platforms, custom systems), we first understand the problem and then put together a proposal with clear scope, stack and timeline.

Professional SaaS / Custom development

For complex products: multi-tenant SaaS, internal platforms, custom systems.

FAQ

About custom development and integrations

If your question isn't here, message us on WhatsApp and we'll answer ourselves.

Yes. Before proposing to replace anything, we analyze what exists: database, available APIs, possible integrations. In many cases the solution isn't to throw everything away but to connect what already works with what's missing. If a migration is needed, we do it in parallel so the operation doesn't stop.
