Sirsi Corporation

Sirsi Corporation, doing business as Sirsidynix, is a foreign-owned, for-profit software publisher headquartered in Lehi, Utah, that sells integrated library system (ILS) software, cloud-hosted subscription services, and annual maintenance to federal agencies almost exclusively as a prime contractor—100% of its recent awards carry prime designation. The company competes in full-and-open, non-set-aside procurements across 168 distinct federal customer agencies and holds no SBA certifications. Sirsidynix derives roughly 24% of its recent award volume and 25% of its combined potential value from the top five customers: the Department of the Air Force (107 awards, $1.8 million combined potential value), the Department of the Army (105 awards, $435 thousand), Naval Sea Systems Command (66 awards, $1.6 million), Naval Education and Training Command (44 awards, $1.5 million), and Army Training and Doctrine Command (44 awards, $2.6 million). The concentration is shallow and diffuse—no single customer dominates, and the top-value customers by different measures diverge slightly, with Air Education and Training Command anchoring $3.4 million (42 awards) and RDECOM bringing $2.9 million (43 awards).

Sirsidynix's federal footprint is dominated by purchase orders for its branded integrated library system platforms: EOS.WEB, Sirsidynix CORE, Symphony, and Horizon. These platforms automate library operations including acquisitions, circulation, cataloging, digital asset management, and public access functionality. Recent representative work includes a $224,415 five-year subscription for technical library software renewal at Air Force Test Center (awarded April 2024), a $291,013.70 EOS.WEB license subscription with the Air Force Research Laboratory through August 2027 (August 2022), a $217,999.61 contract with Army RDECOM for Symphony ILS software maintenance and subscription through May 2025 (May 2022), and a $201,739.54 EOS.WEB enterprise software contract with an unnamed Technical Center through July 2025 (September 2023). Most awards are firm fixed-price purchase orders for software subscriptions, annual maintenance renewals, and licensing—typically in the $10,000–$180,000 range—concentrated in PSC codes for information technology software (500 awards), maintenance and repair of ADP equipment and software (123 awards), and annual software maintenance service plans (67 awards). The company serves over 23,000 libraries across 70 countries and has held its federal portfolio continuously since at least 1991.

Vehicle presence is minimal. Sirsidynix holds position on Federal Supply Schedule GS35F0483M (29 task orders, $498 thousand combined potential value) but does not anchor significant government-wide acquisition contracts or agency-wide IDIQs. The company places nearly all work through direct purchase orders rather than through parent contract vehicles, which limits teaming-partner visibility and indicates Sirsidynix competes and wins on its own merits in a largely commodity subscription market.

Activity has been volatile: 27 awards in 2022, declining to 14–16 in 2023–2024, then recovering to 26 in 2025; only 6 awards appear in 2026 year-to-date (as of mid-July), suggesting either delayed reporting or a shift in award-reporting cadence. The 1,524 total awards in the source carry a combined potential value of $50.6 million against obligated dollars of $54.4 million, indicating mature renewals with inflation and extended contract periods accounting for the over-obligated position. Twenty-eight awards (combined potential value $2.3 million) face ultimate completion within the next twenty-four months and therefore expose Sirsidynix to recompete risk concentrated among its largest repeat customers. The company's subcontracting footprint is negligible—only two sub-awards are documented, both recent and minor: a software subscription sub to Massachusetts Institute of Technology Lincoln Laboratory (November 2025) and another to Valkyrie Enterprises LLC (October 2024).

Sirsidynix's federal positioning is that of an entrenched, single-product incumbent vendor serving a broad and fragmented installed base across defense and civilian agencies. The company competes on product maturity, established integrations, switching costs, and brand recognition in the library automation market rather than on set-aside status or vehicle advantages. Foreign ownership and lack of SBA certifications preclude participation in socioeconomic set-asides, which are not material to its competitive posture in this market segment. The shallow customer concentration and high award count relative to dollar value underscore a business model anchored on renewal subscriptions and maintenance support rather than large-scale implementations or transformational contracts.
