Companies I have built.

A running list of the companies I have founded, led, or helped build. Two are live today:

Story Stream Editor

Deep narrative analysis for fiction writers.

A multi-agent AI manuscript editor built for novelists. Hundreds of writers have trusted us with their work in progress.

Story Stream is the product I wanted when I was writing my own novel and could not find tooling that actually understood a manuscript. Most AI writing tools either rewrite your prose in their voice or spit back surface-level line edits. We took a different path: deep story understanding.

The system uses advanced NLP and AI to train a suite of specialized agents on a writer’s novel. One agent reads for structure, one for theme, one for reader response, one for craft. Each one is grounded in a deep model of that specific book, not a generic rubric. The agents do not write the novel for the writer. They read it carefully, and they help the writer see what is actually on the page.

Hundreds of novelists have trusted us with their work in progress: literary fiction, mystery, romance, sci-fi, memoir-as-novel. The goal is always the same. Make the writer a better writer, in their own voice, by giving them the kind of read a great developmental editor gives, on demand, at manuscript scale.

Family OS

A proactive household assistant.

A small operating system for a household: shared tasks, calendar-aware deadlines, and a proactive assistant that makes judgment easier to exercise.

Family OS is a small operating system for a household: shared tasks and recurring work, calendar-aware deadlines, and a proactive assistant that helps with the research and planning that comes with actually owning something — not replacing judgment, but making it easier to exercise.

Background daemons scan email, calendar, and tasks; an LLM synthesizes what matters into a structured inbox; the web app surfaces each item and one click executes the action. Both partners look at the same picture over time: who owns what, what is due soon, and what holding it requires right now.

Same discipline as Story Stream — intent and context routed first, judgment as a first-class layer — sized to a household instead of a manuscript.

“Quality is the hardest thing, right after cache invalidation and naming things.”
