What SIMS does
SIMS (Siddhi Integrated Manufacturing Services) is a US-headquartered contract manufacturer providing precision machining, fabrication, molding, cleanroom assembly, and managed finishing services to customers in aerospace, automotive, defense, firearms, and medical industries. The company was founded in 2021 in Clarksville, Indiana as a minority women-owned business enterprise, and operates a dual-facility model with US production in Indiana and a 50+-year manufacturing legacy in India. End customers are enterprise buyers issuing project-based Requests for Quote (RFQs) across regulated and high-tolerance applications, with no publicly disclosed long-tail or SMB volume.
The core technology stack is multi-axis CNC precision machining, including 5-axis milling, Swiss-style turning up to 9-axis, EDM (sinker and wire), stamping, and both plastic and metal injection molding. Quality is supported by a climate-controlled 20,000 sq ft Indiana facility and a metrology lab anchored by a Mitutoyo Crysta Apex S 9106 CMM with Renishaw scanning probes, optical comparator, and hardness testers. The company holds ISO 9001:2015, AS9100D, and ITAR certifications in both the US and India, a Type 07 Federal Firearms License (FFL 07) with ATF registration for firearms manufacturing, and an Indiana MBE certification. Products span precision-machined components, fabricated metal parts, MIM components, cleanroom-assembled sub-assemblies, and value-added services (wet processes, NDT, heat treatment, metal joining, grinding, EDM, 3D printing) bundled under managed contracts.
SIMS operates a sales-led, RFQ-driven GTM: a website with a quote-request funnel, direct enterprise outreach led by President & CEO Neelam Neotia, and sales offices covering Europe (Cypress, UK), the Middle East (Turkey), North America (Mexico), Asia (India), and Central & South America (Costa Rica). Revenue is generated through custom project-based contracts quoted per part, with multi-year contract cadence implied rather than published pricing tiers. There are no public funding rounds, M&A activity, or institutional ownership disclosures; the company remains privately held, founder-led, and self-funded.
