We build the systems that companies run everything on
Williams Esfandiari is an operational technology firm. We exist for companies that have outgrown their tools and need infrastructure they can depend on for the next decade.
Why companies come to us
There is a pattern we see in almost every company we work with. The business has grown. The operation has become complex. And the tools that got them here — the spreadsheets, the disconnected software, the legacy systems held together by one person who knows where everything lives — can no longer keep up.
Orders fall through cracks between systems. Collections slow down because nobody has a single view of what's owed. Production planning happens in someone's head because the ERP was never configured for how the plant actually runs. Reporting takes days because the data lives in six places.
These companies don't need another software vendor. They need someone who understands how operations actually work and can build the system that ties everything together — permanently.
That is what Williams Esfandiari does.
What defines us
"Will you actually understand our operation?"
We have built systems for manufacturing floors, distribution networks, and commercial operations across Mexico and the United States. We don't start with templates. We start with your team, your process, and your real constraints. The system we build reflects how you actually work — not how a software vendor thinks you should.
"Will you still be here in three years?"
We operate every system we build. We are not a project shop that delivers and moves on. Our business model depends on your system running well for years. Our incentives are aligned with your long-term success, not with closing the next project.
"Is this going to be another technology project that fails?"
We deploy in stages, validate at every step, and do not call it done until your team is running on the system in production. We have seen enough failed implementations to know that the risk is never the technology — it's the process of getting from here to there. That's where we spend most of our attention.
The Esfandiari relationship
Williams Esfandiari is an associated firm of Esfandiari, the entity that owns the core technology, intellectual property, and systems architecture behind everything we build. This means the platform your business runs on is centrally governed, continuously maintained, and designed for long-term operational use. The architecture is institutional. The relationship is personal.
