Voxel Labs builds production-grade LLM agent systems for high-growth startups, handling the hard parts after a demo works—evals, guardrails, cost control, and reliability at scale. The company also develops Cortana, an agent-native work platform where every surface is both a human UI and an agent tool, exposed through 19 MCP tools. Their work spans unattended agents, retrieval over millions of documents, and voice/realtime systems that navigate IVR and hold queues.

Problem
High-growth startups often struggle to move LLM agents from a working demo to reliable production systems. The hard parts—evaluation, guardrails, cost management, and reliability at scale—are frequently skipped or underestimated, leading to systems that break in production, generate unexpected expenses, or fail to meet quality standards.
Solution
Voxel Labs provides production LLM agent systems that handle the difficult engineering work after the demo works. They build agents that run unattended with retries and approval gates, implement retrieval over real corpora with citations that domain experts accept, and develop voice and realtime systems that navigate IVR and hold queues. The company also emphasizes evals, guardrails, and cost instrumentation so teams know whether their systems work and what each request costs before the invoice arrives. Their approach includes sizing eval work appropriately—distinguishing between two days and two months of evaluation effort—to help teams make the right investment decisions.
Target Audience
Primary customers are high-growth startups that need production-grade LLM agent systems, particularly engineering and product teams that have working demos but need help with evaluation, reliability, and cost management at scale.
