Where AI meets ambition.

Heyman Ventures

We build software businesses at the speed of thought.
And they fund a mission:
preserving the history of computing.

The Mission

Restore the wonder

“The internet is forever” is a lie. Retrology fights bit rot every day — preserving the software, hardware, and documentation of computing history, then teaching what’s underneath. It’s the legacy work. Every business we build funds it.

Preserve

A private archive that rescues operating systems, applications, and documentation from disappearing before they’re gone for good.

Teach

A public library of writing and browser-native tools that make the invisible visible — showing how computers actually work, and why it matters.

Fund

The ventures below are the engine. Their returns flow back to the mission, so the preservation work never depends on anyone’s permission.

Approach

How we build

One founder, AI-amplified, taking ambitious systems from concept to production in weeks, not quarters.

AI-Native

Every project is built with AI at the core — not as an afterthought, but as the foundation. AI shapes the product, the process, and the pace.

Full-Stack

From business model to deployed software. Strategy, design, engineering, and launch — all under one roof, all accelerated by AI.

Battle-Tested

Four decades of building software, products, and companies. Now compressed and amplified by AI into something entirely new.

About

The Founder

Bill Heyman has spent four decades building software, products, and companies — from breaking Apple II copy protection as a teenager, to shipping IBM operating systems, to creating the first iPhone app to reach a million downloads. His background spans mathematics, science, and engineering, with deep experience in hardware integration, high-speed data acquisition, and analysis systems.

Heyman Ventures is the studio he runs today: a portfolio of software businesses built solo and AI-amplified, each one designed to fund a single long-term mission — preserving and teaching the history of computing through Retrology.
