About OpStack Pro
OpStack Pro is a product operations stack that turns domain expertise into daily execution. It connects expert agents, your documents, and real data so decisions happen fast and with context.
OpStack Pro is a product operations stack built by a solo founder. It's designed for founders and operators who need expert answers without assembling a full team.
One-person company today, focused on building durable systems before growing the team.
Expert agents in legal, finance, marketing, and operations, grounded in your files and data.
An ecosystem in progress: OpStack Pro + OpStack App working as a single operational stack.
Sebastian Luna is a Product Operations & Systems Architect focused on turning operational chaos into scalable digital systems.
I turn operational chaos into digital systems that execute. From a spreadsheet to a full SaaS, I design the stack and flow so teams scale without losing control.
OpStack Pro is built for that: expert agents with memory and real data that turn decisions into execution. My focus isn't just which tool to use, but how to orchestrate the system so it scales without friction.

My current project is born from personal frustration: the fragmentation of knowledge in AI.
My vision is that the 'common person' —the solo architect or small business owner— has access to the professional team that today only large companies can afford. I'm building AI agents with long-term memory that act as expert consultants in marketing, design, taxes, legal, and finance.
