ERF SANTOS CONSULTORIA LTDA is an independent consulting firm headquartered in downtown Rio de Janeiro. We work with owner-led businesses on the operational, organizational and data infrastructure decisions that determine whether the next stage of growth actually happens.
The firm was registered on October 31, 2000, and has operated continuously from the same headquarters in the Centro district of Rio de Janeiro ever since. Our main economic activity is management consulting (CNAE 70.20-4-00), with a secondary activity in data processing, application services and internet hosting (CNAE 63.11-9-00) that supports engagements where technology decisions are part of the mandate.
We do not resell third-party services, we do not act as a lead broker, and we do not operate a franchise model. Every engagement is signed and executed under ERF SANTOS CONSULTORIA LTDA, and the working team is composed of the firm's own consultants. The trade name "ERF Santos Advisory" is used exclusively by us to identify this website and our external communications; the domain, the content and the trade name are wholly owned by the company.
Our client base is made up of Brazilian small and mid-sized companies — typically family-owned or founder-led — that have outgrown intuition-only management and need a structured second opinion before making a hiring, capital or infrastructure decision. We work in Portuguese with our clients and publish this website in English so that international partners, suppliers and prospective collaborators can review who we are before making contact.
Each engagement is scoped in writing, priced as a fixed fee or monthly retainer, and executed by our own consultants. We do not subcontract client-facing work and we do not operate through third-party affiliates or resellers.
Diagnostic reviews, competitive positioning and multi-year planning for owner-led companies preparing for growth, succession or capital events. Deliverables typically include a written strategic memo, a financial model and a quarterly cadence with the executive team.
Process mapping, role definition, governance frameworks and internal controls for companies that need to move from founder-dependent operations to a repeatable structure. We work alongside the client's team rather than replacing it.
Under our secondary activity in data processing and hosting, we advise on the selection, configuration and governance of the operational data stack — from bookkeeping systems to reporting layers — so that management decisions are supported by reliable numbers.
Support for clients preparing for external audits, tax reviews or LGPD compliance assessments. We help translate regulatory requirements into concrete internal procedures and documentation the company can maintain on its own.
A one-hour meeting — in person or by video — to understand the situation, the decision on the table and whether we are the right firm for it.
A short document setting out the scope, deliverables, timeline, team and fee. Nothing starts before the client signs it.
Weekly working sessions with the client team, interim memos and a shared workspace where documents and decisions are recorded.
A closing memo, a documented set of procedures the client can maintain internally, and an optional follow-up cadence for the following quarter.

"We hired the firm to help us restructure our management routines before bringing in an outside investor. The team was patient, methodical and stayed on the file until the numbers made sense to everyone in the room."
"What I appreciated most was the straight talk. They told us where our internal reporting was weak, wrote it down, and then helped us fix it step by step. No slides, no jargon."
"A long, quiet engagement that produced a set of procedures we still use two years later. That is the outcome we were paying for."
An introductory conversation is complimentary and takes about an hour. We usually reply within two business days.
