Inkdrop
$10K+/month MRR, solo developer, v6 in development
Japanese solo developer. Maintains Inkdrop alone since 2016. YouTube channel @devaslife (212K subs) drives most of Inkdrop's users.
Takuya Matsuyama was a Tokyo-based developer frustrated that no note app combined offline capability, fast sync, and real Markdown support. In 2016 he built Inkdrop for himself, launched it publicly with subscription-only pricing, and has run it alone ever since.
The Receipt
“I tried InkDrop and couldn't justify the steep price point for something so trivial. I backup everything on my own and watch Boostnote grow as a competitor, but free...”
“Features can easily be stolen, but communities and brands are hard to replicate.”
