Methodology

1. Purpose

fractional-csuite.com is an independent comparator. It does not place executives, take commission on engagements or sell talent. Its function is to publish neutral, source-attributed market data across eight fractional C-suite roles and eight European countries so that buyers can shortlist providers, anchor rate expectations and understand local regulatory context before making a hiring decision.

Credibility depends on visible methodology. Every claim, number and shortlist on the platform is traceable to a public source or to verifiable provider data. This page documents the rules.

2. Selection criteria for provider shortlists

A provider qualifies for inclusion in a country-specific shortlist when all of the following are true:

• The provider publicly markets fractional or interim services for the role in the target country (website copy, press release, case study).
• Public proof of execution exists in the form of named client references, case studies, press coverage or a published rate card.
• The provider responds to inbound contact within a reasonable window (used as a service-level proxy, not a ranking factor).
• The provider is structurally independent of fractional-csuite.com. Self-references are prohibited per editorial rule, see section 6.

Inclusion is not a recommendation. It is a statement that the provider exists, operates publicly and is large enough or established enough to compete in the named market.

3. Scoring rubric

Provider scores published in country and role-country comparison tables (rating values between 4.0 and 5.0) are a weighted composite of four dimensions:

Scores are reviewed monthly. A score drift of more than 0.2 between refreshes triggers a manual editorial review before publishing.

4. Source catalogue (32 named public sources)

Every rate range, market sizing claim and engagement model statistic published on the platform is anchored to one or more of the public sources below. Citations appear inline next to the claim and at the bottom of pricing sections. Sources are reviewed annually for accuracy and currency.

5. Refresh cadence

Provider tables and rate benchmarks are reviewed on a rolling monthly cycle. Each entry carries a lastVerified date visible in the source. The most recent date across all entries appears in the TrustBar at the top of every page.

Country regulatory context (IR35, portage salarial, ZZP, Scheinselbstständigkeit, Partita IVA, etc.) is reviewed quarterly, or sooner when a named source publishes a material change. The 2025 Wet DBA enforcement window in the Netherlands and the DDIM Marktstudie 2026 release are recent examples of triggered out-of-cycle reviews.

Methodology changes themselves (this page) are versioned in section 7 below.

6. Conflict-of-interest policy

The platform does not include itself in any shortlist it publishes. Self-references to fractional-csuite.com or Elite Fractional CxO are systematically excluded from listicles, country tables and comparison matrices. This is enforced by a pre-publication grep check and documented in the editorial-rules incident log.

Providers that have entered into editorial partnerships (content collaborations, data exchange, jointly published research) appear in shortlists with identical row treatment to every other provider, scored against the same rubric, with the partnership disclosed inline in the provider description where material.

No commercial relationship between the platform and a listed provider influences ranking. Rankings are a function of the rubric in section 3 alone.
