Mark Fulton
Solo founder and developer. Writes and builds the card decks behind this site.
Mark Fulton is a solo entrepreneur and developer with 27 years of experience building, launching, and marketing products on the web. He built QuestionCard because good flash cards and question decks kept ending up in cluttered apps and awkward PDFs — a deck of cards should be a pleasure to flip.
Twenty-seven years of building for the web, most of it solo: writing the code, writing the copy, and finding out the hard way which parts of a launch actually matter. That's the perspective the articles on this site are written from — what happened when I shipped something, not what a content brief said should happen.
Where a post makes a factual claim that can be checked — a rate, a standard, a study — it cites the primary source so you can check it rather than take my word for it.
Elsewhere
Most of what I write lives on a handful of properties, each with its own beat:
- Reinventing.AI Insights — articles and guides on AI agents, evaluation loops, and vibe coding.
- Favors.dev — trade favors, earn points, launch faster. A community for indie builders who need eyes on what they shipped.
- 199.domains — a curated marketplace of domain names at $199 or less, with owner verification and 72-hour transfers.
- PounceDomains — around-the-clock domain discovery, data enrichment, drop catching, and portfolio management.
- markfulton.com — the personal site.
