Best Self Publishing Platforms Companies in United States

Ranking the best Self Publishing Platforms companies in the United States by disclosed equity funding and recent momentum, our directory tracks 116 active players — and right now, not one of them has broken into disclosed external funding territory. Zero unicorns, zero disclosed rounds. So what's actually moving this sector? App-store traction, for one: median install growth is running at roughly +13% year-over-year across 516 publishing apps, which tells you the audience is there even if the venture checks aren't. As shown in 2015 research on open-access publishing dynamics, distribution reach tends to outpace monetization in early platform cycles, and that pattern is very much alive here.

The real question you should be asking is where the money eventually flows. Coverage of the space is rising, and if you're sizing up options, this breakdown of which platforms actually pay authors most is worth your time. Names like 30dc, 90-Minute Books, and Adams Media anchor our list right now purely on directory presence, not funding heft. I'd watch that install-growth curve closely. Platforms winning on mobile distribution tend to be first in line when consolidation or institutional money finally arrives.
