Hexaware Technologies vs Sigma Software Group: overview

Hexaware Technologies

Hexaware Technologies was founded in 1990 and is headquartered in Navi Mumbai, Maharashtra, India, with 58 offices across 28 countries and more than 31,000 employees. Its Agentverse platform ships with 600+ ready-to-deploy agents across technology and business operations, and the firm has partnered with Factory to extend agent-native software engineering into regulated sectors like banking and financial services. For procurement-driven buyers, the breadth of pre-built agents can shorten RFP evaluation cycles, though it also means the depth of any single custom agent build may trail a boutique specialist's.

Sigma Software Group

Sigma Software Group was founded in 2002 and is headquartered in Stockholm, Sweden, with more than 2,100 professionals across 40 offices in 19 countries and over two decades of continuous operating history. Its AI practice spans AI-assisted development through agentic task execution in well-bounded modules, emphasizing quality and predictability in real production codebases, and it contributes to industry initiatives on agent-based interactions in programmatic advertising. Its wide European office footprint is an asset for procurement teams weighing GDPR-aligned data residency, though its agentic AI work is scoped more narrowly (well-bounded modules) than some competitors' full multi-agent architecture offerings.
