About
Kenji breaks down SaaS tools for technical founders shipping their first product. Focuses on developer tooling, no-code, and AI infrastructure.
The story
Kenji shipped his first SaaS in 2019 and started writing about the stack he wished someone had explained to him. Four years later his LinkedIn essays move developer tooling: a single Linear post drove 3,400 trial signups in 72 hours. He refuses sponsor money for anything he has not used in production for at least 30 days - which is why his audience trusts the link in his bio.
Who their fans are
80% male technical founders, CTOs, and senior engineers aged 28-45. US, UK, DACH, and remote-first hubs. They make purchasing decisions for their teams - average company size 10-200 engineers. High intent for paid tools that ship serious work faster.
