Sigma Software

Sigma Software is a technology consulting and development company founded in Ukraine with offices across Europe, the Middle East, and the Americas. The firm has 23 years of experience building and modernizing software products, with a track record of delivering 50+ products actively used by Fortune 500 companies and technology startups alike. The company works on everything from greenfield product development to legacy system modernization, data engineering, cloud infrastructure redesign, and cybersecurity.

The core of Sigma's work sits at the intersection of strategy, engineering, and outcomes. Rather than positioning itself as a generalist outsourcer, the firm describes its approach as turning strategy into "practical steps" — which means starting with discovery and technical assessment to clarify where AI and automation create real impact, then building and testing ideas under real conditions before scaling. The methodology moves through four phases: clarify and align priorities, build and prove through prototypes, scale and integrate at production readiness, and operate with managed support and continuous delivery.

Services and capabilities

Sigma organizes its offerings around six core areas. AI-powered software engineering involves structured pilots where teams apply AI to coding, testing, refactoring, and delivery workflows while maintaining human oversight and measurable rollout paths. Data engineering focuses on building trusted data foundations that move beyond reporting into operational workflows, AI, and secure ecosystem exchange — modernizing fragmented estates into scalable platforms and reusable data products.

Cloud and infrastructure work targets redesign of cloud environments for AI workloads, resilience, and sovereignty, helping clients modernize across public, hybrid, sovereign, and private paths. Cybersecurity is embedded throughout delivery, covering security maturity assessment, compliance frameworks, and continuous monitoring. Embedded and IoT connects devices and sensors into reliable ecosystems with real-time control and operational integration. Experience design covers digital journeys, reducing friction in conversion and onboarding flows, cross-channel continuity, and balancing AI guidance with user control.

For product development specifically, Sigma offers MVP development to validate ideas quickly, full-cycle outsourced product development using modular architecture, and product reengineering and modernization. The firm also provides product strategy consulting, UX design, architecture design, quality assurance, information security testing, and ongoing support (1st, 2nd, and 3rd line) and maintenance.

Notable work

Sigma's case work spans multiple industries and scales. For a major advertising ecosystem, the firm built a high-load real-time analytics platform processing 100K+ events per second, supporting instant insights across 400+ metrics used by advertisers and operations teams globally. Latency dropped from hours to minutes.

In medical device and healthcare, Sigma led a multi-vendor cloud migration initiative with Microsoft and Databricks, moving 15+ years of historical data and redesigning ETL pipelines for near-real-time analytics. The new Azure-based setup improved platform scalability and accelerated data processing. A separate engagement with a global healthcare software provider conducted a security maturity audit across 260+ services, established an OWASP-based maturity framework, and implemented custom real-time monitoring.

For an automotive aftermarket platform, Sigma supported migration of 240+ servers and 100+ applications to AWS, modernizing from monolithic to modular services. The platform now manages spare parts data from 900+ automotive brands and processes 200+ requests per second under production load.

Longer-term partnerships include 15+ years as core engineering partner to Formpipe's ECM portfolio (used by ~80% of Swedish government institutions and covering ~90% of the Swedish long-term archiving market with 30K+ daily users and 40M+ documents). Another engagement modernized a SAS budgeting ecosystem, cutting costs by 50% — achieved two years ahead of plan — and reducing fuel budget calculation time from 70 hours to 25 minutes.

Product work includes the Zapp360 SaaS platform (built from MVP to revenue-generating product in 6 months, later acquired by A4 Media), an open-world AR shooting game for BlackSnowGames Inc. with advanced geo-positioning and gameplay, and The Minnits educational game now used in schools across Sweden, Denmark, Germany, Czech Republic, Spain, and Colombia.

How they work

Sigma's engagement model emphasizes discovery and alignment before build. Initial phases involve technical assessment, validation through prototypes, and proof-of-concept work before committing to full-scale delivery. The firm uses lean product development approaches to shorten time-to-market and modular architecture to enable experimentation. For product work, the firm offers complementary services — product strategy, UX, CTO, and InfoSec consulting — within a single engagement setup. Ongoing work includes managed support, monitoring, and continuous delivery to maintain performance and guide improvements through data-driven insights.

Team and credentials

The company has offices in multiple locations across Europe, the Middle East, Northern America, and Latin America. Team size and founder details are not specified in available materials. Sigma holds ISO 14721 and ISO 15489 certifications for long-term digital preservation work and maintains GDPR and WCAG compliance across product portfolios. The firm has contributed to industry initiatives around AI-driven advertising infrastructure, Prebid standards, and emerging monetization models in programmatic advertising.
