Staff Manager: from spreadsheets to a platform for 1,000+ collaborators

Staff Manager is a case study in what changes when product leadership and hands-on build sit with the same person. I led discovery, defined the product and shipped the platform with AI-assisted development for a confidential organization with more than 1,000 collaborators.

The problem

A community-driven organization with more than 1000 collaborators across Italy managed its entire operation through spreadsheets: compensation, reimbursements, payments, communications, document signing, role-based access and course management. Every process required manual work.

At this scale, fragmentation increased errors and management costs grew with the number of collaborators. The organization needed a proprietary platform, but the initial estimate called for two developers working for six months. The budget was available; the time and resources to dedicate to the project full-time were not.

The approach

Building a product from scratch and taking it to production had been a long-standing goal. Staff Manager gave me the opportunity to do it and to see what changes when the person who understands the problem can also build the solution.

I managed the entire product development flow, from discovery to production, working evenings and weekends. I divided the scope into four macro milestones, defined the roadmap and architecture, and used AI-assisted development to explore solutions, produce code and anticipate regressions. Product decisions, validation and control of the process remained in my hands.

The goal was to turn product decisions into software more quickly while maintaining control throughout the process. Because I understood the business context and the team’s problems, I could design the interface, assess the choices and translate them directly into code. With Staff Manager, I became not only a Product Manager but also an AI Product Builder.

The result

One month after launch, Staff Manager had onboarded more than 1000 collaborators and achieved a CSAT of 4.8 out of 5.

Role-based access made processes consistent and traceable: each person sees and manages only the activities within their area of responsibility. The platform manages and tracks digital signatures, document storage, expense reimbursements, courses, communications, compensation processing and payments, bringing into one system what was previously spread across spreadsheets and email chains.

The takeaway

Staff Manager showed me that the boundary between product management and development is no longer as rigid as it once was. When the person who understands the problem can also build the solution, requirements, interface and code evolve within the same learning cycle. The value does not come from generating more software, but from reducing the distance between decision and feedback while maintaining control over priorities, architecture and quality.

This is what I mean by AI Product Builder: a Product Manager who, when the context calls for it, can take a product from discovery to production and build it firsthand.
