Production-ready.
Controlled.
Operational.

19 years of enterprise IT. One focus today: the context layer your AI agents answer and act from.

I build it on a temporal knowledge graph: facts from chat, tickets, wiki and CRM, each with its source and the time it held, read with each person's own permissions, and actions governed by explicit approval or scoped standing consent. On your own tenant, billed by the hour, with an hour estimate for each phase before you commit to the build. How I build it →

Three pillars of production-ready AI.

01Decision confidence

Check. You know before you invest whether and how your pilot becomes production-ready. Production-readiness audit: risks, costs, and compliance gaps, prioritized by impact.

02Controlled execution

Build. Hourly billing, clear phases, human approvals, and limited access rights. Integrated into your system landscape instead of an isolated AI demo.

Agent control: how approvals run in production →

03Operational readiness

Harden. Monitoring, sandboxing, error handling, rollback, and clear ownership. The system holds up in live operation, not just in testing.

No pilot without a path to production. No automation without clear ownership.

Five use cases. Shipped production-ready.

Real client projects with measurable results: problem, solution, metrics, and the path into operation.

Production Self-Hosted Voice AI Platform For Data-Residency-Sensitive Teams

A production-oriented self-hosted voice AI deployment with measured warm-path latency (0.3s combined on the dual-GPU L40S + L4 stack), persistent state for fast ramp-up, and a structured writeback contract so every call feeds back into sales, support, product, and ops — deployable in EU infrastructure today and migratable into a client-owned VPC when required.

Enterprise AI PII Redaction System for Sensitive Documents

What clients say about working together.

René has a strong instinct for identifying operational weaknesses that others often overlook. In our work together, he was always the one questioning existing processes and finding practical ways to improve efficiency. He thinks in solutions and delivers results.

A clear process. From idea to outcome.

Automation that runs like infrastructure, not like a chatbot. The 2026 shift: agents are managed execution environments. Every workflow I ship runs with memory, approvals, sandboxing, and rollback: the four guarantees that separate a production system from a demo.

01

Understand

We analyze your processes, challenges, and goals.

02

Design

We design the architecture around process, data, and risk. With a clear roadmap and an hour estimate for each phase.

03

Build

We build, integrate, and test – iterative and transparent.

04

Operate

Monitoring, defined rollback, and a clear operating model after go-live.

Context layers on temporal knowledge graphs for enterprise AI agents.

René Zander

19 years of enterprise IT. One focus today: the context layer your AI agents answer and act from.

I am René Zander. I build context layers for AI agents on temporal knowledge graphs, backed by 19 years of IT experience from mid-size companies to Fortune 500 and 50+ delivered projects.

No generic AI workshop. No chatbot demo. I work with teams whose assistant already reads chat, tickets, wiki and CRM and now has to answer from the current state and act only with a person's approval.

I maintain Graphiti Local, an open-source, local-first temporal knowledge graph with read-only MCP tools and writes only after a person approves.
