About Stuart Karon
Stuart Karon, operating as Spiral Software, a sole proprietorship based in San Francisco, California, sells physician and hospital scheduling software (AMiON Enterprise) to federal healthcare agencies as a prime contractor, competing exclusively in full-and-open procurements with no set-aside designation across its federal portfolio.
Spiral Software has delivered eighty federal prime awards totaling $3.6 million in combined potential value since 2005, with $3.1 million obligated (86% of potential). The vendor's capability footprint is narrow and specialized: AMiON is a scheduling, on-call contact management, mobile application, and messaging platform designed for military and VA medical facilities. Representative work includes a $859,520 firm fixed-price AMiON Enterprise software license awarded by the Defense Health Agency on September 28, 2022, performing at Brooke Army Medical Center (Fort Sam Houston, Texas) through September 2027; a $113,715 definitive contract with the Defense Health Agency on October 21, 2021, for AMiON software licensing and services at Norwich, Vermont, running through October 2026; and an $83,790 firm fixed-price purchase order from the Department of Veterans Affairs, Veterans Integrated Service Network 4, on January 10, 2022, for AMiON software licenses in Philadelphia, Pennsylvania, with ultimate completion in January 2027.
Customer concentration sits with healthcare-focused federal buyers. The Defense Health Agency dominates by dollar value (7 awards, $1.5 million combined potential value), followed by VA VISNs 20, 16, and 19 (combined 14 awards, $656 thousand). By award count, the top five customers—Air Education and Training Command, Air Mobility Command, Air Combat Command, and VA VISNs 19 and 21—account for 46% of awards but represent only a fraction of the vendor's dollar volume, signaling that VA and DHA relationships anchor the bulk of contract value while Air Force MAJCOMS place smaller, frequent licensing orders. The vendor serves seventeen distinct federal agencies. Across seventy-one awards categorized under NAICS 541511 (Software Publishers), Spiral Software's work is entirely prime; the vendor carries no subcontract footprint. Activity has declined: six awards annually in 2018–2019, dropping to three in 2022. Five awards (combined potential value $1.2 million) reach ultimate completion within the next twenty-four months, presenting recompete exposure.
