Show HN: Copost – A team LinkedIn tool inspired by 37signals and PostHog

Hello HN !

The Problem:

LinkedIn Company pages are dead. The only way to win is "Employee Advocacy" (empowering team members to post on personal profiles to build their own brand + company reach).

The Solution:

Existing tools for this are stiff corporate chores. So we built copost. Heavily inspired by 37signals and PostHog, we traded the boring spreadsheet vibe for a vintage "Postcard" UI. It’s colorful, tactile, and completely anti-corporate.

Under the hood:

   - The "Algo Hack": You can schedule team likes/comments before the post goes live. This signals quality to the algorithm immediately upon publishing.

   - Security First: No shared passwords. You can post on someone's behalf without asking for their login details.

   - Gamification: We built a shared "Team Streak" (like Snapchat) to make consistency a multiplayer game.

Feedback: I’m curious if you think this playful "Postcard" UI makes the process less painful for teams, or if you find it too bold for a B2B tool?

Thanks ! - Alexandre
