Open Source Expertise Sirius Open Source specializes in open source services for mid-market to enterprise clients, presenting a clear opportunity to upsell managed services, support contracts, and custom development around open source stacks like Asterisk, PostgreSQL, OpenLDAP, and Linux.

Enterprise Stack Capabilities Their ability to deploy a full enterprise stack spanning communications, application servers, web, email, and directory services suggests cross-selling potential across networking, collaboration, and infrastructure modernization projects for existing clients.

Notable Brand Experience With prior engagements for Pepsico, Sony Ericsson, Specsavers and others, Sirius has a credibility tailwind to target large organizations seeking proven open source delivery, facilitating introductions to IT leaders responsible for cost, risk, and modernization initiatives.

UK Education Pioneer As the first Becta-accredited open source supplier to UK schools, Sirius demonstrates a track record in public sector adoption and security/compatibility requirements, opening doors for education-focused migrations, licensing clarity, and ongoing support services.

Growth and Footprint With a revenue range and a lean team (2-10 employees), there is room to position Sirius as a nimble, cost-effective partner for specialized open source projects, cloud readiness assessments, and outsourced DevOps or platform engineering engagements.
