The comparison draws on 40 high-relevance pages profiling Mercury or SHW — official Mercury pages, U.S. Senate and FARA lobbying disclosures, and independent reporting. The peer list publishes exactly ranks 1–100 of a validated 120-firm reserve pool (ranks 101–120 are held back as audit reserves), one row per canonical firm, each with its source link; research was conducted 2026-11-10.
Each dot is one of the 100 displayed firms. Horizontal position counts distinct service families detected in that firm's source text (lobbying/GR, public affairs, strategic comms, crisis, digital, research, grassroots, international); vertical position is the relevance rank (1 = most similar to the two reference models). Dots are jittered within rank bands to stay distinguishable. Hover or tap a dot for the firm's services and source.
Mercury is the scaled archetype: part of Omnicom Public Relations Group, with federal government relations, international affairs, digital influence, opinion research, media strategy and a 50-state grassroots network under one roof — marketchameleon.com
SHW is the boutique archetype: a single-member LLC owned by principal Jason Miller, registered under FARA for the Republic of India and under the LDA with $621,663 of disclosed lobbying income across 28 filings for 6 clients, 2020–2026 — efile.fara.gov, legilist.com
Both earn the same way — retainers and registered client engagements: SHW's quarterly LDA reports show per-client amounts such as $150,000 and $120,000, while Mercury reports 550 clients globally across 15 offices — opensecrets.org, mercuryllc.com
The 100 peers deliberately span both archetypes — scaled integrated networks like APCO Worldwide (30+ offices, 80+ markets) and senior-led boutiques like Beacon North Strategies — across 12 named base countries — rfp.wiki, revenuebase.ai
Every statement links its source page. Lines marked "inference" are analytical readings of the sourced facts, not claims a source states verbatim.
Ranks 1–100 of the validated pool. Blank cells mean the sources did not state the value. "Mentions" counts independent source mentions — a confidence signal, not a quality score; the underlying similarity score is a relevance-ranking signal, not a probability, and is omitted here.

Discovery. Explorer split the search among global rankings and directories, U.S. and European lobbying and public-affairs sources, and regional sweeps across Canada, Latin America, Asia-Pacific, Africa, the Middle East, Australia, France and Germany — thousands of web results yielding 1,000+ structured candidate mentions before normalization.
Canonicalization. Coordinator unified entity names, separating current firms from legal suffixes and legacy variants, one row per canonical firm. Spider traced ownership, agency-network affiliations, office reach and structure.
Consensus and signals. Bee treated repeated mentions across independent domains as a consensus signal (shown as "Mentions"); Owl detected service-language and geographic signals in source text.
Ranking. Evaluator scored similarity to the two reference models. Comparability means an external-client consultancy with lobbying or government relations at the core, or tightly integrated with public affairs, policy advocacy, political strategy, reputation and crisis work, strategic communications, corporate diplomacy or geopolitical advisory.
Adversarial filter. Challenger and Hyena rejected software products, directories, trade bodies, in-house teams, individuals, public agencies, generic consultancies, marketing-only agencies and consumer-PR firms without demonstrated public-affairs capability. This is role-based analytical execution, not a claim that every firm is identical to both references.
Caveats. The list intentionally spans two archetypes — scaled integrated networks resembling Mercury and senior-led boutiques resembling SHW. Public sources often omit private-firm revenue, headcount and commercial terms, so relevance rests on service mix, delivery model, market position and geographic reach. Some rows remain single-source discoveries; judge them by their mention counts. No single URL supports a majority of the list.
Method: two result sets gathered 2026-11-10 — 40 pages profiling Mercury Public Affairs and SHW Partners (official sites, LDA/FARA disclosures, independent reporting) and a ranked 120-firm validated reserve pool; ranks 1–100 are displayed, ranks 101–120 are unpublished audit reserves. Service-breadth in the chart counts matches of eight service-family keyword groups in each firm's sourced service and scope text; blank cells are preserved where sources stated no value; similarity_score is a relevance-ranking signal and is not shown; per-row evidence quotes were cut for space.
