What I Learned Building Solo AI Tools: On Limits and Leverage

Solo founders building AI tools hit limits that are structural, not effort-related. Working harder doesn't fix them. Three limits and three leverage points — the ones that actually matter.

The AI Panel That Changed How I Think About Agents (Seattle Tech Week)

I expected the usual conversation about model selection and prompt engineering. What I got was a room full of builders talking almost exclusively about failure modes and environment design.

Which Cialdini Principle to Lead With for Each B2B Buyer Type

Cialdini's six principles work. The problem is knowing which one to lead with for the specific buyer in front of you. In B2B, getting that wrong isn't neutral. It costs the deal.

Nightwatch: What I Built When I Needed Someone to Work While I Sleep

I had a list of monitoring and research tasks that never got done. Not because they weren't important — because they required sitting at a computer. So I gave a machine the keys.

The B2B Cold Email Personality-Fit Framework: Write to the Role, Not the Average Prospect

Most cold email advice is about getting opened. That's not where the deal dies. The deal dies in the body copy — after the open — when the message is calibrated for a generic prospect instead of the person reading it. The B2B cold email personality-fit framework addresses that second failure mode: m

How to A/B Test Email Subject Lines by Personality Type

Most email A/B tests are designed to find a winner. The problem is that the winner is an average across people who wanted completely different things — and the test can't tell you which variant worked on whom.

Personality-Based Marketing for B2B SaaS: The Signal Your Segments Are Missing

Personality-based marketing for B2B SaaS means calibrating your copy's frame, language, and appeals to the buyer's Big Five trait profile — not just their job title or plan tier.

Audience-Fit Scoring for B2B Communications: The Pre-Flight Check A/B Testing Can't Do

Audience-fit scoring measures how well a piece of B2B copy matches the specific profile of its intended audience across four dimensions: personality traits, emotional engagement, message clarity, and cognitive framing. The score runs before the copy ships. Not after. Before.

Why B2B Marketers Are Moving from Demographics to OCEAN Personality Scoring

The OCEAN model (also called the Big Five) identifies five personality traits that predict how B2B buyers process and respond to copy. Applied to B2B marketing, it answers a question that demographic targeting can't: not just who is reading, but how they will evaluate what you say.
