IT Service Alliance

What IT Service Alliance does

IT Service Alliance (ITSA) is a U.S.-based, employee-owned IT Managed Service Provider launched on August 30, 2024, that consolidates legacy and mission-critical IT infrastructure services for Enterprise and Fortune 500 customers. The company operates through three wholly owned subsidiaries — The Parsec Group (acquired August 2024), Baer Consulting / BCL Mainframe Services (acquired January 2025), and Salem IT / Salem Automation (acquired October 2025) — and serves 200+ enterprise customers across healthcare, financial services, government, defense, industrials, retail, and education. ITSA's core offering comprises seven integrated service modules: Remote System Support, Disaster Recovery as a Service (DRaaS), Managed Hosting, Managed Services, Migration & Modernization, Professional Services & Consulting, and Staff Augmentation, augmented by Mainframe-as-a-Service (MFaaS) and a global reseller arrangement for ColeSoft's IBM Z solutions.

Technically, ITSA supports both modern and end-of-life platforms spanning OpenVMS, AIX, Tru64, UNIX, HP-UX, Oracle Solaris, Linux, IBM Z mainframe, IBM i, and x86 environments. Differentiating capabilities include heterogeneous DRaaS covering IBM Z mainframe, IBM i, AIX, and x86 physical/virtual — a footprint most DRaaS providers lack — and legacy system emulation technology delivered through a VSI partnership that enables OpenVMS, Tru64, and HP-UX workloads to run on modern x86 or cloud infrastructure. All service delivery is U.S.-based and onshore from secure operations centers, with 24x7x365 coverage, and the company holds a comprehensive compliance stack: SOC 2 Type II, ISO 27001, PCI DSS 4.0, FISMA, HIPAA, HITRUST, and CSA STAR.

ITSA's business model combines recurring managed services contracts (multi-year, quote-based with tailored SLAs), Time and Materials consulting at 1.0x/1.5x/2.0x rate multipliers for after-hours/holiday work, Firm Fixed Price project engagements with change-order governance, and hourly/project staff augmentation. Go-to-market is direct enterprise sales targeting Fortune 500 buyers in regulated industries, complemented by channel partnerships (Izzi Software for IBM Z reseller) and partnership-driven referrals with hardware vendors, VARs, and system integrators. The company is majority founder- and employee-owned under a broad-based Employee Ownership Plan, has no outside PE/VC control, and was capitalized with a ~$3.6M equity and debt round in August 2024 dedicated exclusively to further acquisitions. ITSA was recognized on the Inc. 5000 list of fastest-growing private companies in 2025 (rank #2,575).
