Ways to start
Every engagement starts with a free diagnosis. Projects are quoted at a fixed price, so you know the cost before we write a line of code.
30 minutes
Free
We map one process that costs your team hours and tell you whether software, data or AI can fix it, and roughly how.
2 to 4 weeks
Fixed price after the diagnosis
We automate one real process with your data, so you measure the result before any larger investment.
Phased rollout
Fixed price after the diagnosis
Our ERP adapted to your plant: attendance with NFC cards, overtime, turnover, transportation and HR records.
Monthly
Fixed price after the diagnosis
An engineering team on call for improvements, new reports, integrations and maintenance.
Who you work with
Phronesa is led by Alexis Pérez, a software engineer on the US-Mexico border. He builds systems in .NET and Python, data pipelines and AI automation, and you talk with him directly from the diagnosis to the delivery.
Process
A free call to map the problem, your data and what success looks like.
A working slice in weeks, so you see value before the full build.
Short iterations with a demo every week. Code and docs are yours.
Monitoring, improvements and training for your team after launch.
FAQ
Yes. Most projects start by connecting what already exists: SQL Server, Excel files, ERPs, CRMs or plain CSV exports. We replace things only when it pays off.
Tell us about it. In 30 minutes you will know whether we can automate it, and how.
