Systems engineering in the age of AI

Building voice systems, agent fleets, and reality-graded products

I'm Zak El Fassi — Founder & CEO of Talk & Comment, former Head of Messaging Product Partnerships at Meta, and Co-Founder & CTO of INK + PORCELAIN. I write field notes on AI, infrastructure, and human coordination from inside live systems.

Voice products, agent fleets, and operating notes from production

What I'm building now

Three live fronts: voice, agents, and small-company systems

Talk & Comment, scoped agent operations inside live messaging channels, and the systems behind INK + PORCELAIN. The rule is simple: serve roots, use frontier tools.

Talk & Comment

The voice platform I started in 2013. Today it carries AI-native workflows for learning, assessment, and feedback.

Agent fleets

Scoped agents running across WhatsApp and Telegram with memory, escalation, operating cadence, and patch notes when reality breaks the abstraction.

INK + PORCELAIN

I co-run the technology and supply-chain systems behind a rare-art and one-of-a-kind home objects business.
