A Coxswain on Your Shoulder

In rowing, the coxswain watches everything. How hard you pull on every stroke. Whether you’re in time with the rest of the boat. How your form breaks down when you’re tired. They’re among the most valuable people in a rowing team.

At work, I don’t have a coxswain. So I built a robotic one.

Every night it reviews my meetings & coaches me on how to improve, whether they’re one-on-ones, pitch meetings, or other calls.1

Is Your Margin My Opportunity in Software?

Jeff Bezos famously said, “Your margin is my opportunity.”1 Does this maxim apply in software & AI? Yes.

Software companies maintain 76% gross margins yet earn almost nothing. Sales, marketing, & research & development consume it all.

Among 69 publicly traded B2B software companies, the median net income margin hovers near zero.2 Gross margins cluster tightly around 76%, yet almost none of that profit flows to the bottom line.

The Model T Comes to Silicon Valley

In 1908, 253 American automobile manufacturers competed for the market1. By 1929, just 44 remained. The assembly line didn’t just change how cars were made. It changed who got to make them.

The Great Auto Industry Consolidation

Ford’s Highland Park plant, operational in 1913, slashed the time to build a Model T from 12 hours to 93 minutes2. That 90% productivity gain restructured an entire industry. Manufacturers who couldn’t match Ford’s efficiency faced a simple choice : adapt or exit.

AI Managing AI

Talented people get promoted to management. So do talented models. Claude manages code execution. Gemini routes requests across CRM & chat. GPT-5 can coordinate public stock research.

Why now? Tool calling accuracy crossed a threshold. Two years ago, GPT-4 succeeded on fewer than 50% of function-calling tasks. Models hallucinated parameters, called wrong endpoints, forgot context mid-conversation. Today, SOTA models exceed 90% accuracy on function-calling benchmarks1. Performance of the most recent models, like Gemini 3, is materially better in practice than the benchmarks suggest.

When the Market Questions Relevance

Will designers design first in a world where AI can code software immediately, or just describe the design? Will large enterprises pay for premium observability when AI can migrate & monitor open source competitors?

As Michael Mauboussin writes, there’s information in price. These questions are priced in. It’s too early to see revenue erosion, but the market is pricing in the risk.

The median SaaS stock is down 14-17% year to date. 64% of software companies are down. Adobe has fallen 32%, HubSpot 57%, Atlassian 54%.

The Postmodern Data Stack is AI

After a decade of success, the modern data stack has entered consolidation. What comes next?

The postmodern data stack is AI.

The modern data stack created more than $100 billion in market cap with a simple promise : move the data via ETL, transform it inside a cloud data warehouse, put a semantic layer on top of it to unify metric definitions, & analyze it through BI.

The original modern data stack architecture with ETL, warehouse, semantic layer, & BI

This worked brilliantly for structured data, numerical data found within tables. But AI & businesses thrive on unstructured data, such as call transcripts, status reports, web searches, & PDFs.

Software That Debugs Itself While I Sleep

This week I chatted with an acquaintance who mentioned a board game. I caught half the title & looked for the full title & Amazon link using my AI in Asana.

Board Game Query Failure
AI Agent Failure Logs

The system tried with Gemini & failed. The failover to Claude also failed. Rather than continuously iterating with the AI until it worked, I created a Ralph Wiggum loop.

A Third Time Up the Roller Coaster

AI is NVIDIA’s third climb up a steep slope.

First came gaming in the late 2010s.

Then cryptocurrency.

Now artificial intelligence.

Each wave pushed revenue growth above 50% & with it, P/E1 ratios surged. P/E ratios rose before the revenue growth materialized.

There’s a four-quarter offset between P/E ratio & TTM2 revenue growth. When you shift revenue growth forward by a year, the correlation with P/E jumps to 0.80.

Dead Companies Walking

“[Silicon Valley] is the biggest, most volatile petri dish of raw capitalism on the planet.” So what lessons does a successful short-seller living here have? As founder of Crown Capital Management, Scott Fearon has shorted the stocks of over 200 companies.

In his book Dead Companies Walking, Fearon distills three decades of meetings with executives into six failure modes :

Despite their differences, they all failed because their leaders made one or more of six common mistakes that I look for :
