2. Revised Timeline (Now → End of March)

Late February — Vision & Foundations

Post 1 “DataHub: The Home for Indie Data Publishers”

Post 2 “Multi-Author Publications Are Live”

Post 3 “Markdown-First Data Publishing”

Goal: establish platform legitimacy.


Early March — AI-Native Publishing Launch

This becomes a distinct mini-launch arc.

Post 4

“Introducing the DataHub CLI”

Content:

  • datahub publish dataset.csv
  • Works from terminal
  • Works in GitHub Actions
  • Works in scripts

Post 5

“DataHub API: Programmatic Data Publishing”

Content:

  • REST endpoints
  • Metadata schema
  • Example curl
  • Example Python snippet
  • Token auth

Post 6

“Let AI Publish to DataHub”

Content:

  • Example: agent generates dataset
  • Agent publishes via API
  • Automated update workflow
  • Use cases: daily stats, market feeds, research bots

This sequence creates technical credibility before monetisation.


Mid-to-Late March — Payments Arc

Post 7

“Subscriptions for Data Are Coming”

Preview:

  • Paid datasets
  • Subscriber-only access
  • Revenue model for data publishers

Post 8

“Earn Recurring Revenue From Your Data”

Launch post.

This sequencing matters:

AI publishing → then AI can publish paid data → then recurring revenue.


3. Why AI Before Payments Makes Sense

  1. Establishes DataHub as infrastructure, not just a site.
  2. Attracts technical publishers early.
  3. Creates automation use cases.
  4. Makes monetisation feel like a natural extension.
  5. Differentiates from Substack before you compete on pricing.

It signals: this is not a clone — this is programmable.


4. Optional: Tactical Framing for AI Posts

Keep tone consistent with overall vision. For example:

  • “Substack for Data — Now With a CLI”
  • “Publishing Data Without a Browser”
  • “Automate Your Data Publication”

No need to reposition the whole brand.
