Companies we're
building right now.

We are founders who never stopped building. The companies below are ones we're actively operating today — not managing from a distance. We bring that same energy to every founder we back.

Active Companies & Current Pursuits

We build alongside
the companies we back.

We're in the work every day alongside these companies. That's why we understand what it takes — and why founders who work with us say we're different.

AI Sales Engine

Active · Growth Stage · Autonomous Sales & Marketing aisalesengine.ai
Active

An autonomous sales and marketing engine for owner-led businesses — 34 integrated capabilities working independently or alongside existing staff. It analyzes markets, expands pipelines, nurtures and closes, and produces all of its own content, campaigns, and emails without manual input.

Targeted to double the size of a business within two to three years. Active, profitable, and growing.

AdvancedWebsites.ai

Active · Growth Stage · AI-Powered Web Design & Operations advancedwebsites.ai
Active

AI-powered web design and ongoing website operations for B2B and B2C businesses. Produces sites that formerly cost $25,000–$50,000 at a fraction of the cost — and then continues to run them: marketing, outreach, nurturing, and prospect handling through seamless AI and CRM integration.

The website becomes a live marketplace outpost — expanding into new states, segments, and industries, and delivering personalization capabilities once reserved for the Fortune 500 to a business of any size.

Modern Publishing

Active · Early Stage · Multi-Channel Publishing & Content fighthomefraud.com
Early Stage

Multi-channel publishing for authentic domain experts — on-demand books, audiobooks, podcasts, courses, and continuing education — helping leaders in real estate, public safety, and technology reach their audiences through every available channel.

We are acquiring both multi-titled properties and individual properties with multi-channel potential. An active example: our work with a leading housing fraud expert in New York State at fighthomefraud.com.

Public Safety Technologies

Active · Early Stage · First Responder AI & XR Platforms In Development
Early Stage

Technologies that directly assist first responders through AI and XR — at the scene of fires, accidents, and inspections — alongside administrative platforms that help police departments and first responder agencies operate more effectively at city and state level.

AI becomes a force multiplier. XR becomes the eyes and ears of professionals on scene. These capabilities represent the future unification of technical expertise with the professional expertise hard-earned by the frontline departments we all rely upon.

What Our Companies Have in Common

A pattern you can see.

Every company we build or back reflects the same convictions about where durable value gets created. These are the threads that run through everything we do.

01

Founder-Led and Founder-Operated

Every company in the portfolio has a founder still in the seat, still making the calls. We don't back companies where the original operator has been replaced by a management team. The founder is the asset — and we protect that.

02

AI as Core Capability, Not a Feature

AI is woven into the foundation of every company we build — not retrofitted as a selling point after the fact. Each company uses AI to do something that was previously impossible or prohibitively expensive at the scale they're targeting.

03

Large, Underserved, or Emerging Markets

Every company addresses a market that is either very large and poorly served by current solutions, or newly emerging because technology has made something newly possible. We don't back incremental improvements to crowded spaces.

04

Built to Lead or Built to Be Acquired

Each company is building toward a clear outcome — category leadership or strategic acquisition by a known class of buyer. We know who the buyers are before we build, and we build toward them deliberately from day one.

05

Operating Today, Not on a Roadmap

Every company in the portfolio is active and operating — serving real customers, generating real revenue, and solving real problems right now. We don't hold pre-revenue or pre-product positions.

06

Authentic Domain Expertise at the Center

Behind every company is genuine, hard-earned expertise in the domain it serves. We look for operators who know their market from the inside — not entrepreneurs who spotted an opportunity from the outside. That expertise is what makes the AI work.

The Lens We Work Through

Artificial Intelligence —
The Unifying Capability.

AI represents a unifying capability that we see as simply an extension of what computing productivity, efficiency, and repeatability brought to civilization over the last fifty years — only far beyond that.

AI — whose horizon is unknown as it leads into quantum computing — represents an extraordinary ability to strengthen owner-led businesses dramatically. It brings more intelligence, more insight, reduces risk, and allows businesses to experiment, innovate, invent, test, and market at essentially no cost.

"We combine authentic domain expertise with force multiplier technologies. That is the investment thesis, the operating philosophy, and the reason we show up every day."

All activities that once carried upfront expense — reduced margins, increased organizational risk — can now be done repeatedly across many iterations. The organization advances continuously. We look for existing expertise to combine with these force multiplier capabilities in every company we back.
