Signal & Noise: a weekly AI brief for decision-makers

The AI news that matters, with the hype filtered out.

I read ~25 AI newsletters every week and distill them into one sharp, five-minute brief: the strategic and financial so what for executives, minus the noise. Written by me, Michael Carswell, a forward deployed engineer who builds this stuff for a living.

Join decision-makers who’d rather read one good email than twenty mediocre ones.

Why Signal & Noise

Most AI newsletters are link dumps. This one has a point of view.

Signal vs. noise

Every claim is filtered through a hype-vs-evidence lens. If the data is thin or a number looks too good, I say so, out loud.

A strategic + money lens

Not just what happened, but what it means for your business, your budget, and where value is actually shifting in the market.

Five minutes, weekly

Synthesized from ~25 sources into a single brief you can read before your coffee gets cold. A 30-second version up top for the busiest weeks.

Who’s writing this

Hi, I’m Michael.

I’m a forward deployed engineer. I embed with teams and ship AI systems that actually make it into production, not just demos. Signal & Noise is where I share what I’m learning from the firehose of AI news. This site is also where I post the projects I build along the way.
