Building SaaS.
Sharing the journey.

I'm Jonas. I look for opportunities worth building, then build the startups myself. The first is Clienzo, a social media scheduler. This is where I write down how it gets built: what shipped, what broke, and how I got past it.

Write a post once. Publish it to every network your business uses.

A social media scheduler for founders, freelancers and small agencies — with a public API and an MCP server, so posts can come from the app, a script or an AI assistant.

  • One composer for 16 networks, with a preview of how each network will show the post
  • Queue, calendar, media library and drafts
  • A delivery result for every network, and retry for only the ones that failed
  • Analytics with blanks where a network reports nothing, instead of guessed numbers
  • One inbox for comments from Facebook, Instagram, Threads, Bluesky, Mastodon, DEV and Tumblr
  • A public REST API and an MCP server for posting from scripts and AI assistants

16 networks live · Vimeo uploads in review · TikTok and X not yet supported
