The product is the whole system.
Code, experience, infrastructure, messaging, documentation, support, and operations all shape whether the product works.
ABOUT / THE REASON FOR BEING
Capability,
brought into true.
Prumo Works exists so a small team with strong direction can build the whole product—and make it hold up in the world.
THE REASON
WHYGreat products have traditionally required large organizations.
Enough specialists, processes, and operational capacity to understand, decide, build, verify, operate, learn, and improve.
That has kept many capable people from attempting the products they can imagine. It has also forced small teams to choose which essential parts of the job to neglect.
AI gives us a chance to change that equation. But the opportunity is not to generate more software that merely looks finished. It is to encode more of the capability of a great product organization into tools.
WHAT WE BELIEVE
THE STANDARDProfessional software needs professional judgment.
Agentic systems change who can do the work and how it moves. They do not change what customers deserve.
Production is the standard.
Reliability, security, accessibility, observability, performance, and maintainability are product features—not finishing touches.
Launch is the beginning.
A product must be operated, supported, repaired, explained, improved, and kept relevant throughout its life.
Agents should own outcomes.
Useful agents gather context, plan, use tools, coordinate work, produce an outcome, and verify that it holds up.
People keep responsibility.
People set intent, exercise judgment, approve consequential decisions, and remain accountable for what reaches customers.
Leverage should raise the ceiling.
The promise is not merely cheaper software. It is more people able to attempt ambitious products without lowering the bar.
THE NAME / O PRUMO
prumo
NOUN · PORTUGUESE
A plumb line: the weighted tool that tells you whether something is truly vertical.
Direction you can measure against.
In Portuguese, prumo names the physical reference used to bring a structure into true. Figuratively, it also carries the sense of prudence and good judgment. That combination is our standard: clear human direction, work kept aligned with it, and proof that the result holds up in use.
DIRECTION
People set the intent and define what good looks like.
ALIGNMENT
Every build stays tied to that intent as the work moves.
PROOF
What ships has to stand straight in production, not only in a demo.
THE FOUNDER
RODRIGO SILVEIRA
LONDON, UK
Built from experience taking products from first build into real use.
Prumo Works was founded by Rodrigo Silveira, a London-based product and engineering leader with more than 15 years of experience building and leading teams across big tech and startups.
His work spans consumer products, developer platforms, voice AI, and coding agents. Prumo brings that experience together around one ambition: give small teams more of the capability of a complete product organization while keeping human direction, judgment, and responsibility intact.
