In Generative AI Services, Firstsource is a Leader in Strategy and Consulting Services and in Development and Deployment Services, the second consecutive year it has led both. In Agentic AI Services, it is a Leader in Agentic AI Development and Deployment Services. Together, the three quadrants cover the full path of Kairos, Firstsource’s operating system for AI-native operations. Its Transform, Implement and Operate model takes clients from deciding where AI should change work, to engineering that change into production, to running agents within governed workflows. Hasit Trivedi, Chief Digital & AI Officer, Firstsource, said, “Enterprises don’t need more AI pilots. They need to rethink how work gets done: redesigning processes, using GenAI where it adds value and giving agents clearly defined responsibilities, with human judgment at the right points. Ultimately, they want outcomes delivered. At Firstsource, Kairos is how we make that real: Intelligence That Operates. ISG’s recognition across strategy, engineering and agentic execution reflects that full-stack Transform, Implement and Operate approach.” Gowtham Kumar Sampath, Assistant Director & Principal Analyst, ISG, said, “Firstsource combines domain-led GenAI with governed agentic execution, embedding contextual intelligence into enterprise workflows and progressively extending AI from assistance to coordinated action. Its Kairos, Intelligent Context Framework and Agentic AI Studio connect process knowledge, orchestration, human oversight and runtime governance, creating a foundation for scalable, controlled AI-driven operations.” What ISG highlighted Across the two reports, ISG highlights Firstsource’s operations-led approach that keeps AI strategy tied to how work will actually run. It also cites reusable domain engineering that lets clients start from proven, productized components rather than bespoke builds. In agentic AI, ISG points to agent design grounded in domain playbooks, orchestration through Agentic AI Studio, and the Intelligent Context Framework (ICF). The ICF captures the exceptions and decisions that standard procedures miss, so each deployment strengthens the next. ISG also emphasizes that as agents act across enterprise systems, permissions, escalation paths and human oversight matter as much as the agents themselves. Firstsource’s aim is not maximum autonomy but reliable execution within clear boundaries, with autonomy extended as trust is earned.
