Mark Fulton
Solo founder and developer. Writes and builds the typing test 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 TypeTimer to prove a typing test can be fast, private, and free of sign-up walls.
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.
