What a guide is
A guide covers one specialty in one market. There are 52 guides: 13 specialties across 4 markets, United States, San Francisco, New York City, and Miami. Each guide has the same parts: a ranked list of specialists, a written assessment of each one, a section on how to choose in that specialty, answers to common questions, and the list of sources the guide relies on.
Guides are written for buyers, such as founders and product or growth leaders preparing a shortlist. They are not written for the specialists in them.
- Define the specialty Each guide covers one specialty in one market: consultants, agencies, or fractional operators.
- Read the public record Assessments are written from service pages, published work, talks, and professional profiles.
- Link every claim Each entry links to the sources it relies on. We publish no ratings or scores.
- Date it Every guide shows the date its research was done. The date changes only when a guide is re-researched.
Who is included
Each specialty names one type of specialist: consultants, agencies, or fractional operators. A consultant guide can include an expert-led boutique, and an agency guide can include a clearly described specialist alternative when that helps a buyer, but every entry is typed as what it is. A solo consultant is never presented as an agency.

How entries are assessed
Assessments are written from public sources: service pages, published work, talks, interviews, and professional profiles. Each entry links to the sources it relies on, and the guide lists them again at the end. Across the current guides that is 227 sources from 156 source sites.
Entries appear in ranked order. The order is our judgment of fit for the guide's specialty and market, based on the public record. We publish no ratings, scores, or reviews.
The Best for line is the key field. It says what kind of buyer and problem a specialist suits, as far as the public record shows. Read it with the location and engagement details, then follow the sources.
An assessment is not a review, not a client reference, and not a claim about current availability or price. Confirm scope, availability, and terms with the specialist before engaging them.
What location means
National guides list specialists that serve buyers across the United States; each entry still says where the specialist is based. City guides say how each specialist relates to the city, in one of five ways:
- Based in the cityThe specialist's main location is in the city.
- Office in the cityThe specialist lists an office there alongside other locations.
- NearbyLocated in the surrounding region rather than the city itself.
- Serves the city remotelyWorks with clients in the market without a local presence. Remote availability never implies a local office.
- Not confirmedThe public record does not settle the question, and the entry says so.
If in-person work matters to you, confirm meeting arrangements and the location of the people who would be assigned to your project.
Dates
Every guide shows the date its research was completed. All 52 current guides were researched September 3, 2026. A guide's date changes only when it is re-researched, and its date, entries, and sources change together. Guide dates are never generated automatically.
Published pricing, services, and availability can change after the research date. Treat the date as context and check current details before choosing a specialist.
Fees and commissions
We don't take fees or commissions from the specialists we list. If that ever changes, the affected entries will say so on the guide.
Editorial standards
Every guide is written from the public record: service pages, published work, talks, and professional profiles. Every source an entry relies on is linked in the entry and collected at the end of the guide, so you can read what we read. We publish no ratings or scores.
Beatriz Parga, the editor of record, is responsible for these standards and for corrections. When a reader or a listed specialist shows us an error, we fix the entry.
Corrections
If an entry is wrong or out of date, write to corrections@expertshortlist.com with the guide URL, the detail that needs attention, and a public source.
Specialists listed in a guide can link to their entry with the listing badge. For Specialists explains how.
