Pensero is the intelligence behind agentic deployment. As companies deploy AI agents alongside their engineering teams, leaders lose the one thing they need most: an objective view of what is actually getting delivered. Pensero scores every unit of work on the same scale, whether it was human, AI-assisted or agent-only, then shows where each one creates value. That gives you agent performance, cost per unit of work, and agentic transformation, monitored live. Customers call it story points after the fact: an objective measure of what was delivered, comparable across teams, technologies, and any mix of humans and agents. No commits, no hours, no lines of code, no agent activity. Every agent, assistant and human lands in one system of record. Repositories, tickets, chat and AI tools connect automatically, with no instrumentation project and no workflow change. Leaders decide what stays human-led, what gets augmented, and what can be delegated to agents, then optimize that balance against delivery, quality, cost, and business impact. Agent budgets are approved on promise today. Pensero turns them into a portfolio with a return.

The Responsible AI-Agent for organizations where the answer HAS TO BE RIGHT. kama.ai answers from knowledge your team approves, not from what a model guesses. Every response is accurate, consistent, and traceable to its source. Governed by design. How it works: kama.ai is built on a Knowledge Graph AI. Your team curates Trusted Collections of approved information and documents, and the AI Agent answers from them exclusively. Best of all you get consistent answers to the same questions - every time. Governed Generative AI helps with phrasing and coverage within limits you set. Then Intelligent Automation lets the Deterministic AI agent complete multi-step tasks. No hallucinations allowed, where real-world consequences are at stake. This AI doesn’t just answer questions. A Human in the Loop approves key, high frequency questions - to make sure everything is brand-safe. Why it's different: Most AI chatbots generate first and add guardrails afterward. kama.ai works the other way around: Deterministic AI first to guide and orchestrate. Then generative AI helps only where you allow it. This lowers the risk of AI adoption for teams that can't afford a wrong answer about a permit, a policy, the way to fix an expensive machine on the line, a procedure, or their brand. Built for: manufacturers, municipalities, government, colleges and universities, professional services, non-profits, museums, and Indigenous services organizations. Purpose-built to be transparent, accountable, and culturally aware. Get the right information to the right people, at the right time. If it's got to be right, it's got to be kama.ai.
