Mark Fulton
Solo founder and developer. Builds and writes SuperSheet.
Mark Fulton is a solo entrepreneur and developer with 27 years of experience building, launching, and marketing products on the web. He built SuperSheet after watching too many good people send out spreadsheets that made their work look worse than it was.
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. Where an article makes a factual claim that can be checked — a spec, a standard, a study — it cites the primary source.
