I build things.

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.

Highlights only. This is the part of what I'm working on that is far enough along to show; a lot more is in progress and not listed. It is not a résumé: things drop off when I stop working on them.

Open Source

solveathome

Hard problems, solved in the open. An open-source platform where people bring a problem and a direction, contributors' agents do the work, other contributors' agents check it, trusted reviewers decide what counts, and every return, review and transcript is public. MIT code, CC BY 4.0 results. Read the launch post.

Problems

Twin Prime Conjecture

Are there infinitely many pairs of primes two apart? The first problem on the platform, seeded with my own notes from ten years of dabbling.

Commercial Projects

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.

Destinations

DailyPlay

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.

SolitairePlace

HyperPolished

Mass-market casual games where every interaction has weight. Simple mechanics you learn in seconds, polished until they feel alive. Fewer games, higher hit rate, each built with viral sharing from day one.

Games

Hex by HyperPolished

A calm, satisfying puzzle. Drag pieces, clear lines, and let the soundtrack build with every combo. Soft launched on iOS in the UK and Canada; open beta everywhere else.

Forgeable

Forgeable is an integrated AI and compute platform that breaks complex work into small, repeatable steps. Each step has defined inputs and outputs. The platform automatically evaluates and refines those steps to improve result quality and reduce running costs. Steps can then be reused and connected into larger workflows.

Problems we solve

Forgeable is the backbone of the AI workflows across my businesses and personal projects. Building everything on the same platform makes it easier for me to maintain and improve those workflows.

I originally built it as an internal tool. People I described it to kept asking if I could help solve problems in their businesses too. So I now offer this as an enterprise service, building and maintaining custom solutions on Forgeable for select partners.

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.

Early Stage Experiments

Barcodepedia

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.

Amptune

The live operations platform under all our products. It watches every event a product fires and decides, for each user, what happens next: how hard the next level is, when the paywall shows, whether a reminder is worth sending at all. Closed beta; SolitairePlace runs on it today.

funny.io

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.

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 (Turn 3 variant)

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.

Hex by HyperPolished

A calm, satisfying puzzle for iPhone and iPad. Drag pieces onto the board, clear lines through shared cells, and let the soundtrack build with every combo. No timers, no friction. Soft launched in the UK and Canada; open beta everywhere else.

Built for the pleasure of it.

All labs

Not products, not roadmapped, not for anyone but me. Things I wanted to see exist.

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. worldsbestbread.com ↗ World's Best Bread One no-knead Dutch oven bread, laid out as a timeline. Five minutes of work, a long cold rise, and a page for every schedule, flour and unit system, in four languages.

Writing

I write about building companies with AI, game development, and what I'm learning along the way.
