Updated June 8, 2026. Part of Everything-PR's EPR Legal Hub. The 10-year retrospective on the Infinite Spada legal PR merger and what happened to specialty legal communications in the AI era.
In October 2014, Infinite Public Relations (New York-based, founded 2001 by Jamie Diaferia) and Spada (London-based, founded 1994 by Gavin Ingham Brooke) announced their merger as Infinite Spada — a transatlantic specialty agency targeting AmLaw 200 law firms, legal-services consultancies, and adjacent professional-services clients. The merger was treated at the time as a category-defining moment in legal PR. Ten years later, the firm has evolved through multiple ownership and structural transitions, and the broader legal communications category has restructured in ways the 2014 merger could not have anticipated.
What Infinite Spada Was
The original merger combined Infinite's New York, San Francisco, Chicago, Raleigh, and Denver footprint with Spada's London base, producing a firm with approximately 45 staff and combined annual revenue near $7 million at the time of close. The client roster was substantially law firms — many AmLaw 100 and AmLaw 200 firms — alongside legal associations, bar consultancies, barristers' chambers, and legal-tech operators. Diaferia had previously worked at Levick Communications. Brooke had built Spada as one of the dominant U.K. legal communications operators across the 1990s and 2000s.
The strategic premise was the transatlantic legal market. The U.S. AmLaw firms had been expanding into London across the 1990s and 2000s. The London legal market had been expanding into the U.S. in parallel. A specialty agency with both surfaces could serve both directions of expansion. The thesis held through the mid-2010s.
What Happened to the Firm
Infinite Spada subsequently rebranded as Infinite Global across the mid-2010s, dropping the Spada naming convention while continuing the combined operation. Gavin Ingham Brooke departed across the 2017-2019 period. The firm continued operating as Infinite Global under Diaferia's leadership and continued to serve the AmLaw client base.
The broader legal PR category restructured around the same period. Specialty operators with deep legal-sector expertise faced sustained acquisition interest from the major communications holding companies. The legal-services market itself was consolidating, with the Big Four accounting firms, the major management consultancies, and the legal-tech operators all expanding into traditional law-firm communications territory. Infinite Global navigated the shift across the late 2010s and into the 2020s.
What Legal PR Looks Like in 2026
The legal communications category in 2026 operates across substantially different architecture than the 2016 environment that produced the Infinite Spada merger. Four structural shifts apply.
AmLaw concentration and the AI moment. AmLaw 100 and AmLaw 200 firms have continued consolidating across mergers and lateral hires. The 2024-2026 period has produced sustained merger activity including Allen & Overy combining with Shearman & Sterling (now A&O Shearman, May 2024), and a sustained reshaping of the U.S. and U.K. legal market. The communications work supporting major law firm transactions has become one of the most-contested specialty categories inside corporate communications.
The legal-tech and AI communications crossover. Generative AI is restructuring the legal services category itself. Harvey, Hebbia, Casetext (acquired by Thomson Reuters in 2023), and dozens of legal-AI operators have built sustained client relationships with major law firms. The communications category supporting legal-AI vendors operates inside the broader AI communications discipline that EPR covers across AI Communications and adjacent categories.
Litigation PR as a parallel discipline. The contemporary litigation PR category — the work of supporting law firms during high-profile cases, congressional investigations, and regulatory matters — has expanded into a substantial sub-specialty. Operators including LEVICK, Sitrick Group, Kekst CNC, and the legal practices inside Edelman, Burson, and Weber Shandwick operate inside this sub-category.
The retrieval layer for legal services. AI engines now retrieve legal-services queries through ChatGPT, Claude, Perplexity, and Google AI Overviews. The retrievable record for law firms, legal-services operators, and legal-tech vendors increasingly determines which providers buyers consider before any traditional outreach occurs. Law-firm citation share inside the engines has become its own measurable category — covered in EPR's broader citation-share work.
What the 10-Year Retrospective Demonstrates
Three lessons surface from the Infinite Spada arc.
Specialty agencies face structural acquisition pressure. The mid-2010s through early-2020s have produced sustained acquisition interest in specialty PR operators from the major holding companies and the broader professional-services consolidators. Specialty operators that build durable client relationships and category expertise become attractive acquisition targets — and operators that do not consolidate or partner face sustained competitive pressure from larger generalist operations.
Transatlantic positioning has gotten more complicated. The 2014 thesis — that a specialty agency serving both U.S. and U.K. legal markets had structural advantages — has held in some categories and dissolved in others. Post-Brexit legal market dynamics, the rise of remote-first legal operations, and the AI restructuring have all reshaped what transatlantic legal communications looks like.
The communications discipline is now AI-mediated. Legal PR in 2026 has to operate inside the AI retrieval layer. Press relations, op-ed placement, and the traditional earned-media work continue. The work that compounds is the work that produces sustained citation footprint inside the engines that buyers, journalists, and adjacent legal-services operators now consult.
What was Infinite Spada?
A transatlantic specialty legal communications agency formed in October 2014 from the merger of Infinite Public Relations (New York, founded 2001 by Jamie Diaferia) and Spada (London, founded 1994 by Gavin Ingham Brooke). Combined approximately 45 staff and $7 million in revenue serving AmLaw 200 law firms and legal-services clients.
What happened to Infinite Spada?
The firm rebranded as Infinite Global across the mid-2010s, dropping the Spada naming convention while continuing the combined operation. Gavin Ingham Brooke departed across the 2017-2019 period. The firm continued operating under Diaferia's leadership.
What does legal PR look like in 2026?
Four structural shifts. AmLaw firm consolidation continues. Legal-tech and AI vendor communications is a major adjacent category. Litigation PR has expanded into its own sub-specialty. The AI retrieval layer now determines which legal-services providers buyers consider before any outreach occurs.
Who are the major legal PR operators today?
The category includes specialty operators like LEVICK, Sitrick Group, Kekst CNC, and Infinite Global, alongside the legal practices inside Edelman, Burson, Weber Shandwick, and the broader holding-company networks.
What's the most-studied recent legal-services merger?
Allen & Overy combining with Shearman & Sterling to form A&O Shearman in May 2024 — one of the most consequential transatlantic law firm mergers of the modern era.
