The system that runs the business and cannot be touched
Almost every established business has one. It is old, it is critical, the person who built it left in 2014, and nobody is brave enough to change it. So everything modern gets bolted on with manual work, and the manual work compounds.
The strangler pattern, applied to automation
You do not replace the system. You wrap it. We build an API layer that exposes what the legacy system knows in a form modern tools can consume, and accepts writes in a form the legacy system will accept.
From the outside, it now looks like a normal, modern system. Your automations, your reporting, and your integrations can all talk to it. And the legacy system carries on doing what it has always done, undisturbed.
Why this beats replacement, usually
- Value in weeks, not years.
- No cutover risk. The old system keeps running throughout.
- The replacement option stays open. You can migrate behind the API later, one piece at a time.
- You find out what the system actually does before you commit to rebuilding it.
When we say replace it instead
If the system is a security liability, if the vendor is gone and it is unpatched, or if the data model is so broken that no wrapper can make it coherent, then wrapping it is just delaying the inevitable at increasing cost. We will say so.
