Regulatory Consulting at Cornerstone Government Affairs

Overview

Cornerstone Government Affairs is an employee-owned, bipartisan lobbying and government-relations firm with more than 200 employee-owners across 15 states and Washington, DC, named a Top Lobbying Firm by Bloomberg Government in April 2026 based on revenue growth and client-retention performance. Unlike most government-affairs boutiques in this directory, Cornerstone has a documented, active, and current book of AI-specific federal lobbying clients: it represents Snowflake on federal AI policy and Coretsu on AI adoption within Congress itself, giving it a direct, traceable role in how AI companies are shaping federal policy and legislative-branch technology adoption in real time.

AI-Focused Regulatory Work

Cornerstone’s AI lobbying work is unusually specific and well-documented through federal disclosure filings. Its engagement for Coretsu Inc. — which began lobbying in Q3 2025 and paid Cornerstone roughly $90,000 in Q4 2025 as part of a $120,000 engagement running through January 2026 — focuses on securing federal adoption of Coretsu’s AI tools, specifically the ‘utilization of a new Congressional office platform’ aimed at AI adoption within legislative-branch operations. The policy backdrop makes this a genuinely live and current story: the House allocated $4 million for modernization initiatives in December 2025 and identified AI as a ‘top priority’; the bipartisan SAMOSA Act passed the House with sponsors citing potential annual savings of $750 million; and Microsoft’s Copilot chatbot reached up to 6,000 House staffers that same fall — the first major generative-AI deployment inside the legislative branch, arriving amid institutional pressure from the Trump administration’s AI Action Plan to accelerate federal AI adoption broadly. Coretsu’s lobbying disclosures list it as directly competing against Microsoft, Cloud Software Group, CGI Federal, and Data Society Group in the federal AI space — a snapshot of which companies are actually vying to supply AI tools to Congress. Cornerstone separately represents Snowflake exclusively on federal AI policy, a two-person team blending Republican Hill-staff experience (including prior AI-semiconductor lobbying) with Democratic technical-policy expertise; Snowflake’s broader Cornerstone relationship sits alongside the firm’s existing roster of technology clients including General Dynamics and Microsoft. For a directory reader, Cornerstone offers something rare among the government-affairs boutiques: a specific, sourced, and current window into how individual AI companies are lobbying Congress on AI adoption right now.
