Spearhead is an applied AI consulting and engineering firm focused on production-grade AI systems.
Spearhead builds its production agents on the Claude Agent SDK, the same harness that powers Claude Code, using the MCP to discover tools and empower agents to integrate across diverse systems to solve complex use cases. Anthropic's Managed Agents layer adds scheduling and outcome grading on top. In Spearhead's nine-layer Enterprise AI Reference Architecture, this is the Reasoning and Agent layer, the layer that governs how an agent thinks through a problem, not just what data or infrastructure it can access.
Spearhead's clients build on Claude's agent primitives and MCP's library of enterprise connectors directly, rather than reconstructing that layer for every engagement. Spearhead continues its practice of designing with a model agnostic architecture; However Anthropic has increasingly become the default choice for the reasoning and agent layer specifically.
Abhijeet Khadilkar, Founder and Managing Partner at Spearhead, put it this way: "Anyone can wire a model up to a task. The hard part is making it reason the same defensible way every time, and showing your work when someone asks why it made a particular call. Claude's agent primitives and MCP give us that foundation instead of making us build it ourselves for every client."
Clients get a reasoning layer maintained by Anthropic rather than a custom framework built and tested only within a single engagement, and further they inherit the growing number of new MCP connectors being shipped minimizing the need to build custom ones.
