AI-Native Customer & Product Leader

I turn complex problems
into clarity

I've been doing it for twenty years - first securing South Africa's largest enterprises, then architecting cloud for its biggest financial institutions and retailers at AWS, now running post-sales for global enterprises, Fortune 500 to AI scale-ups, at Limina. And every day I build with AI agents. The systems below are in production, not on a roadmap.

Applied AI

Agentic Systems in Daily Production

Not a skills list. These run every day, maintain themselves, and ship real work.

In Production

Company Brain · arx

An LLM-maintained knowledge wiki: plain markdown, hybrid BM25 + vector retrieval, automated ingest from Gmail, Drive, web and PDFs, contradiction flagging. A working implementation of the pattern YC named a Summer 2026 RFS category.

In Production

AI Chief of Staff · Yoshi

An agent I run as my chief of staff: reachable over email and Slack, wired into Linear and GitHub, self-hosted on a Tailscale-locked VPS with tightly controlled access. Drafts briefings, tracks projects, executes recurring workflows.

Shipping

Agentic Product Delivery

Full platforms built with multi-agent coding loops (Claude Code, Agent SDK, MCP, custom skills) on a self-hosted stack. Live now: oohcentral.com (June 2026) and mikebrowntours.com - my wife's and my dad's businesses, built and operated end to end, generating real leads.

Grant's superpower is looking for ways to understand and then simplify solutions to help customers, rather than over-complicating tech discussions. He listens to understand what will really be valuable and works backwards from outcomes.

About

The Person Behind the Work

I started in Johannesburg in 2000 as a generalist IT consultant, and spent my first decade in security - Symantec, then NTT Data - learning the skill that has carried every role since: sitting between deep technology and the people who have to bet their business on it, and making the decision legible.

At AWS that skill got its biggest test. For six years I was the technical partner to some of Sub-Saharan Africa's largest financial institutions and retailers - a $44M+ portfolio, multi-year cloud transformations, boardrooms and build teams in the same week.

In 2023 I moved my family to British Columbia, and the following year joined an AI startup, where I own the Customer Success function end to end for a global enterprise base. Same job as always, new frontier - helping serious organizations adopt technology that is moving faster than their comfort.

Since 2025 the building has gone agentic. I operate an LLM-maintained knowledge system, an AI chief of staff wired into my project tools, and multi-agent coding workflows that ship real platforms - including oohcentral.com, launched June 2026.

Security to cloud to AI. Johannesburg to Cape Town to Gibsons. Advisor to operator to builder. The constant is the translation work in the middle.
