Field notes.
Short pieces I post to LinkedIn and keep here in full — selected, not exhaustive. The arguments that drew the sharpest replies, with a line or two from me on what I'd add today.
Strong opinions on multi-agent architectures
The pitch to build an army of specialized agents and delegate between them doesn't work — you get a distributed monolith. Treat sub-agents as dependencies, not separate services.
“You can't enforce API contracts when your interface is natural language.”
Read the note →How I interview machine learning engineers
How I run ML/AI engineering interviews to find people who can actually ship: no trivia, make the candidate the expert, then stay relentlessly curious.
“Make them the expert, then get relentlessly curious.”
Read the note →Anthropic is converging on code, not tool calls
MCP, then Skills, then code-execution benchmarks: Anthropic's guidance keeps trending toward pairing LLMs with executable code instead of chaining tool calls. Prompt-and-pray is ending.
“Separation of concerns is back in style.”
Read the note →Your AI platform is too data-hungry
A user called Rasa 'data-hungry' — not from benchmarks, but because our docs stressed training-data quality. A lesson in how advocating best practice can hurt perception.
“Sometimes the market will punish you for trying to be helpful.”
Read the note →Don't try to convince your sales team
If you're in product or engineering, don't pitch your roadmap to sales. Good reps are rightly skeptical of features until a real prospect gets excited.
“Good enterprise sales people know not to listen.”
Read the note →Great product managers combine restraint and ingenuity
Restraint, so you don't fall in love with your own clever solution; ingenuity, so you actually commit to a direction. PMs need both, or they miss the mark or spin their wheels.
“Without both, you're either missing the mark or spinning your wheels.”
Read the note →Multi-agents are a hammer looking for nails
A short one. When Gartner asked to quote me on multi-agents being a hammer in search of nails, I said sure — but read the blog first.
Read the note →From 30 under 30 to 2 under 2
Forbes once put me on a 30 Under 30 list. I'm now in a more demanding club: 2 under 2.
“I'm now in a different club: 2 under 2. I can tell you it's much more demanding.”
Read the note →Why I write a weekly newsletter for my own company
As a founder you get pulled into more conversations than anyone else at the company. Writing up what you're seeing every week — in four short sections — turns that information privilege into shared context, and a way to influence without dictating.
“It's also a way to influence without dictating.”
Read the note →Everything that can be code, will be code
A Slack question about hiring a video editor turned into a Remotion + Claude Code + Whisper pipeline for making social videos — the moment video editing collapsed into code for me too.
“Saying "make this transition snappier" and watching it happen is magic.”
