What Ad Hoc LLC does

Ad Hoc LLC is a privately held, founder-led digital services firm headquartered in McLean, Virginia, founded in 2014 by Greg Gershman in the aftermath of the HealthCare.gov launch failure. The company focuses on helping federal, state, and local government agencies close the gap between modern consumer digital expectations and legacy government technology stacks. Its client roster is anchored in major federal agencies — the Centers for Medicare and Medicaid Services (CMS), Department of Veterans Affairs (VA), Department of Labor (DOL), and General Services Administration (GSA) — with state work including the Louisiana Department of Agriculture and Forestry, Wisconsin Department of Workforce Development, and select non-profit engagements.

The company's offering is organized around four service lines — Digital Experiences, Systems Transformation, Data Interoperability, and AI and Agentic Automation — delivered through cross-functional product, design, and engineering teams trained in human-centered design, agile/DevSecOps, and accessibility (WCAG 2.1 AA, Section 508). Its technical stack is built on AWS/Azure/GCP cloud infrastructure, headless CMS platforms including Drupal, API-driven architectures, and increasingly AI-assisted development, with a proprietary toolkit that includes the Activate Framework, cloud.gov AI agent instruction files, and the Drupal Migration Engine. Operational examples of delivery at scale include the rebuilt Medicare Plan Finder (2.6M beneficiaries enrolled, 373K daily visitors, zero downtime during Open Enrollment), the VA Health and Benefits mobile app (2.5M+ downloads), Blue Button 2.0 at CMS (20B health claims from 64M patients accessible via modern API), and continuous HealthCare.gov operation including the Data Services Hub and Enhanced Direct Enrollment.

Ad Hoc generates revenue through negotiated federal, state, and local contracts and as a subcontractor to primes (e.g., Fearless on GSA's Search.gov), using modular option-period structures (typically 6-month increments over 2–3 year terms). Pricing is not publicly disclosed and is set through the RFP process. Distribution is aided by long-standing relationships with the U.S. Digital Service (USDS) and 18F, thought-leadership content (playbooks, field guides, blog), and open-source releases (Activate Framework, Copyright Compendium digital experience, cloud.gov AI instruction files) that serve as both capability marketing and community engagement. The company is privately held with no disclosed outside investors.

Direct peers

• Oddball: A digital services firm of similar scale that built HHS and VA-facing products and was acquired by Maximus in 2024; Ad Hoc and Oddball both emerged from the USDS/18F-aligned civic-tech community and competed for overlapping federal digital modernization contracts.
• Fearless: A digital services firm of comparable size focused on building modern software for federal agencies; Ad Hoc and Fearless even work together on programs like GSA's Search.gov, and both target the same human-centered, agile-style federal delivery niche.
• REI Systems: A mid-size federal digital services firm that has built and modernized citizen-facing applications and data platforms for civilian agencies, including CMS and VA-adjacent work, with a similar human-centered, agile delivery orientation to Ad Hoc.
• Slalom Public Sector: The public-sector arm of a mid-size consulting firm that builds digital experiences, data platforms, and AI solutions for federal and state government customers, directly competing with Ad Hoc on RFPs in CMS, VA, and adjacent civilian agency work.

Broad incumbents

• Accenture Federal Services: A large systems integrator serving CMS, VA, and GSA with digital, cloud, and data modernization programs; offers overlapping capabilities to Ad Hoc but as one part of a much broader services portfolio.
• ICF International: A publicly traded consulting and digital services firm with a substantial federal civilian practice covering health, environment, and civic programs; competes with Ad Hoc on modernization programs at scale.
• Maximus: A large government services firm whose federal segment competes with Ad Hoc on Health and Human Services digital programs; it also acquired Oddball in 2024, directly absorbing a close peer.
• Booz Allen Hamilton: A large federal IT and consulting prime with deep CMS, VA, and GSA footprints; competes with Ad Hoc for the same modernization programs while offering broader past-performance, larger IDIQ vehicles, and full-stack scale.
• Deloitte Government & Public Services: A Big Four federal practice delivering digital transformation, AI, and systems modernization to civilian agencies; overlaps with Ad Hoc on user-experience-led modernization work but operates at materially larger scale and contract scope.

Others

• Code for America: A non-profit civic technology organization that partners with state and local governments on digital service delivery and safety-net program modernization; not a direct competitor but part of the same civic-tech ecosystem that Ad Hoc is rooted in.
