About SDA Software LLC
SDA Software LLC, a self-certified small disadvantaged business headquartered in Sterling, Virginia, sells finite-element analysis and computational mechanics software licensing and renewal services to federal agencies as a prime contractor exclusively. The company specializes in distributing FEMAP with NX NASTRAN and related Siemens Digital Software products—specialized engineering simulation tools for structural analysis, systems modeling, and design optimization used in aerospace, defense, and space applications.
SDA Software operates exclusively on a full-and-open basis with no set-aside designations on the majority of its footprint; recent awards split between non-set-aside and Total Small Business set-aside purchase orders, with the company competing as a qualified small disadvantaged business. The vendor structure is a limited liability company organized for profit, with a discrete product-delivery model centered on software license renewals and maintenance support rather than custom development or services integration.
Customer concentration is extremely tight. NASA's Shared Services Center anchors the portfolio at 7 awards totaling $972 thousand in combined potential value (75% of all awards by count and 75% of all dollars), with the Agency procuring annual FEMAP license renewals to support Goddard Space Flight Center's aerospace engineering and research activities. The U.S. Army's Research, Development and Engineering Command follows at 4 awards, $125 thousand, also renewals of FEMAP with NX NASTRAN for rotorcraft and fixed-wing platform analysis. Naval commands—Naval Sea Systems Command, Naval Air Warfare Center, and Military Sealift Command—round out the active set with 4 awards, $219 thousand, representing maintenance and support for specialized design and analysis tools in fleet systems engineering. All five customer agencies account for 100% of the award portfolio.
SDA Software operates exclusively as a prime contractor; no subcontract footprint is present in the source. The vendor carries no parent vehicles, GWACs, or agency-wide IDIQs; all awards are direct purchase orders under FAR Parts 12 and 13 (commercial item acquisition). Activity has grown modestly from a two-award baseline in 2022 and 2023 to four awards in 2025, with two awards logged in 2026. The combined potential value of $1.3 million is entirely obligated (95% of combined potential value invoiced), reflecting the nature of perpetual-license and maintenance-renewal contracts with predictable spend cycles. Three awards (combined potential value $237 thousand) are scheduled for ultimate completion within the next twenty-four months, creating near-term recompete exposure concentrated with NASA and Army customers. SDA Software's posture as an incumbent sole-source provider of Siemens Digital Software products—particularly FEMAP—to NASA and defense engineering commands positions it to retain renewal business at those agencies, though limited portfolio diversity and zero sub-engagement create vulnerability to agency consolidation or migration to alternative engineering simulation platforms.
