About the company
Sirsi Corporation, doing business as Sirsidynix, a foreign-owned for-profit software publisher headquartered in Lehi, Utah, delivers integrated library system (ILS) platforms and subscription services to over 168 federal agencies as a prime contractor (100% of recent awards), competing predominantly in full-and-open procurements with no set-aside posture. The vendor's federal footprint spans 1,527 prime awards since 1991, with recent activity averaging 18.6 awards per year across 2022–2026 and combined potential value of $50.9 million obligated at $54.7 million.
Sirsidynix's capability portfolio centers on cloud-based and on-premise integrated library system software platforms—EOS.WEB, SIRSIDYNIX CORE, Symphony, and Horizon—that automate acquisitions, circulation, cataloging, public access catalogs (OPAC), and digital asset management for federal libraries. Representative named contracts include a $224.4 million firm fixed-price purchase order (April 2024) with the Air Force Test Center at Edwards Air Force Base for SIRSI-WEB EOS online technical library software renewal through March 2029; a $217.9 million subscription and maintenance renewal (May 2022) with the U.S. Army Research, Development and Engineering Command for Symphony ILS at Aberdeen Proving Ground through May 2025; and a $179.3 million annual software license and maintenance contract (January 2022) with the Smithsonian Office of the Chief Information Officer. The vendor also delivers maintenance, training, consulting, data migration, and IT help desk support across its subscription model.
Customer concentration is distributed across defense and civilian agencies with no single customer dominating the portfolio. The Department of the Air Force leads by award count (107 awards, $1.9 million combined potential value), followed by the Department of the Army (105 awards, $435 thousand). By dollar volume, the Air Force Air Education and Training Command anchors the top position (42 awards, $3.4 million), followed closely by Army Materiel Command Research Development and Engineering Command (45 awards, $3 million) and Army Training and Doctrine Command (44 awards, $2.6 million). The top five customer agencies account for 25 percent of combined potential value, indicating a broad customer base across the federal government. Navy entities (Naval Sea Systems Command, Naval Education and Training Command, Naval Air Warfare Center, Office of Naval Research) account for roughly 170 awards across the portfolio, making the Navy collectively significant alongside Air Force and Army presence.
Sirsidynix places work under the Federal Supply Schedule GS35F0483M (29 task orders, $498 thousand combined potential value) and smaller GSA schedules (GS00K93AGS5695 and GS00K92AGS5948). The vendor does not anchor major government-wide IDIQs; instead, it competes via direct purchase orders and schedule task orders across individual agencies.
Activity trajectory shows modest volatility—27 awards in 2022 declining to 14 in 2024, then recovering to 26 in 2025 with 10 awards recorded so far in 2026. Awards reaching ultimate completion within the next twenty-four months total 26 with combined potential value of $2.2 million, presenting a moderate recompete cliff dominated by small renewal and maintenance orders typical of the vendor's subscription-renewal business model.
NAICS concentration aligns with the vendor's software business: Software Publishers account for 638 awards (41% of the 1,527 total), Custom Computer Programming Services for 228 awards, and Other Computer Related Services for 170 awards. PSC codes reinforce this profile, with Information Technology Software dominating at 499 awards, followed by Maint/Repair/Rebuild of ADP Equipment (123 awards) and Support—Administrative Library (71 awards), confirming that library-specific maintenance and SaaS subscription work constitutes the core federal footprint.
Sirsidynix operates a parent-subsidiary structure; Sirsi LIMITED is listed as a foreign-owned subsidiary. The vendor holds two sub-awards on record: a software subscription sub-award with Massachusetts Institute of Technology Lincoln Laboratory (November 2025) and another MIT Lincoln Laboratory software subscription sub-award through Valkyrie Enterprises LLC (October 2024), indicating minimal subcontractor role and a prime-centric go-to-market posture.
