Sirius Software

What Sirius Software does

Sirius Software JSC is a privately held Bulgarian custom software development company founded in 2011, headquartered in Sofia with a secondary presence in Plovdiv. The firm delivers bespoke web applications, mobile apps (iOS and Android), eCommerce platforms, ERP and CRM systems, real estate visualization tools, travel booking platforms, and gaming/iGaming software for enterprise and mid-market clients. Its core technology stack spans Symfony (PHP), .NET/C#, Java, Node.js, and Python on the backend, with React, Angular, and Vue.js on the frontend, and cloud deployment across AWS, Azure, and Google Cloud. A proprietary Symfony-based development framework and a customizable eCommerce platform serve as the firm's main reusable IP, refined over nearly a decade.

The company operates on a project-based professional services model with fixed-price or time-and-materials contracts, supplemented by managed IT support, DevOps, QA, design, and digital marketing services. Sirius serves a global client base — including BENU Pharmacies (PHOENIX Group, 1,400 locations across 14 countries), Vivacredit, Easycredit, 7Mojos, Nomination, and Seewines — distributed across fintech, ecommerce, gaming, real estate, travel, and entertainment verticals, with a pronounced concentration in Bulgarian non-bank financial services. Go-to-market relies on direct enterprise sales, inbound website inquiries, free estimation calls, and listings on B2B review platforms such as Clutch and DesignRush.

Sirius is founder-led, with Co-founder and CEO Georgi Papucharov and CTO Vladimir Angelov at the helm, and has raised no external funding to date. The firm is ISO 27001 certified, employs 40+ staff, and reports 100+ completed projects over its operating history, indicating stable, self-funded growth rather than venture-backed scaling. Its competitive position rests on vertical domain expertise (especially in fintech and gaming), a 10-year proprietary framework, and end-to-end in-house delivery capability rather than on any differentiated AI/ML capability.
