25 years building companies, games, platforms & tools. Products that have reached more than 1.5 billion users.
Now running Moltke Benjaminsen Alpha, an AI-powered reverse incubator. I build companies from zero to revenue, hand them off to founding teams, and write about the entire process as it happens.
Companies
Great Games Network
A network of direct-to-consumer puzzle game destinations. Evergreen games with near-infinite replayability, targeting older adults as the primary demographic but built for everyone. Each property has its own brand, revenue model, and audience. Powered by a proprietary game framework that enables rapid catalog expansion across all destinations.
Properties
Free online puzzle and card games with no ads. Play Klondike Solitaire, Mahjong Solitaire, Sudoku, and WordSlip with a new daily challenge at midnight, the same puzzle for every player. Streaks, XP, levels, and achievements across a growing catalog of games.
Free solitaire games online. Play Klondike Solitaire, Klondike Solitaire Turn 3, and Mahjong Solitaire. No account required, just play.
Moltke Benjaminsen Alpha
AI-powered reverse incubator. Builds companies from idea to revenue, then hands them off to co-founding teams with significant equity. Founders get a running business with validated revenue, active partnerships, and proprietary technology. They focus on growing it, not surviving the early stage.
Experiments
A wiki-style, structured-data reference for products, indexed by barcode. Every entry is one strict, validated file, edited by people and by AI passes through the same path.
An index of io games that still run. Browser multiplayer games in the Agar.io tradition, sorted by what you actually do in them. Every link is checked; nothing is listed that is dead. No signup, no download.
Writing
I write about building companies with AI, game development, and what I'm learning along the way.

Experiments and graphics demos — things I built to find out if they would work. See all labs.
Blids
Millions of boids flocking in the browser. A WebGPU simulation that runs up to 4 million agents with exact pairwise forces — no sampling, no approximation, and no grid artifacts. Requires a WebGPU-capable browser.
Galaxcelerate
Fly through a procedurally generated galaxy. Millions of stars built on the GPU from a single seed, rendered as additive HDR so density reads as brightness. Requires a WebGPU-capable browser.
Great Games I Made
Klondike Solitaire
Classic solitaire, reimagined as a daily shared experience. Every player gets the same deal each day. No ads, no interruptions. Track your streak, earn XP, and compare your results with friends.
Also on SolitairePlace
Mahjong Solitaire
A tile-matching puzzle where you clear pairs of tiles from a layered board. Simple to learn, satisfying to solve, and the kind of game you can pick up for five minutes or lose an hour to. A fresh layout every day.
Also on SolitairePlace
Sudoku
A fresh puzzle every day at midnight, the same for everyone. Pure logic, no guessing. Pencil marks, hints, and undo built in. No ads, no account required.
WordSlip
An original word puzzle. Seven letters scattered across a hexagonal grid. Find the hidden word, then trace a connected path that spells it out. Part anagram, part spatial reasoning. A new puzzle every day.
