We want to be the premier government digital services agency.

Ad Hoc is a software design and engineering company that came out of the successful effort to rescue HealthCare.gov after its disastrous initial launch.

Ad Hoc is focused on developing, delivering, and operating fast, stable, and well-designed digital services on behalf of U.S. government clients. Our work enables agencies to provide transactional and informational services to their users. We bring technologists together to collaborate closely with government partners, crafting solutions and delivering software that works.
