Scoring a real idea
"A publishing ecosystem for WordPress: as easy as Ghost or Substack, with WordPress's freedom." Every dimension from Part III, applied.
The idea#
A WordPress theme maker with ten years of publishing themes asks: should I build an ecosystem that makes publishing in WordPress as easy as Ghost or Substack, while keeping WordPress's freedom?
Verdict first#
It fits the builder well, and the pain is real and growing. But the market is crowded and "ecosystem" is too big to start with. The average score is about 3.8/5. Since the formula multiplies, the three weak spots decide the outcome: the hole, platform risk and time to first dollar.
Market facts (2026)#
- Money is already flowing. Substack: 5M+ paid subscriptions, writers earned ~$450M in 2025. Ghost: $10.8M ARR, bootstrapped. beehiiv: ~$33M ARR, takes no cut.
- The shift: Google traffic to publishers fell about a third in 2025; small sites lost about 60%.
- Inside WordPress: Automattic already offers Jetpack Newsletter (free, paid subscriptions via Stripe), Newspack and MailPoet. Also Newsletter Glue, MemberPress and others.
- WordPress's share is slipping: 43.6% at the 2024 peak, about 41% now. But the installed base is huge.
Scores (5 = good; for risks, 5 = low risk)#
Market
| Dimension | Score | Why |
|---|---|---|
| People already paying | 5 | publishers pay Substack's 10%, Ghost, beehiiv, Kit, MemberPress |
| Painkiller or vitamin | 4 | painkiller for publishers losing Google traffic |
| Timing / phase | 4 | mature market plus a shift: the third state |
| Hole / competition | 2 | Automattic gives the core away free; "no fee" isn't an edge anymore |
| Market structure | 3 | new writers go to the biggest network; plugins have room for many |
| Segment health | 3 | Google-dependent blogs shrink; owned-audience publishers grow |
Access
| Dimension | Score | Why |
|---|---|---|
| Easy-to-reach segment | 5 | existing theme customers are WordPress publishers |
| Owned vs rented | 4 | customer list owned; wp.org rented but stable |
| Price fits channel | 4 | ~$99–299/year fits list, content and wp.org; no ads |
| Built-in visibility | 4 | a "powered by" footer on every newsletter sent |
| Someone else paid to educate | 4 | Substack, Ghost and beehiiv taught the world "own your audience" |
Builder
| Dimension | Score | Why |
|---|---|---|
| Easy for me | 5 | WordPress publishing is home ground |
| Earned secret | 4 | years of support tickets from small newsrooms |
| Platform risk | 2 | Automattic controls WordPress and competes directly |
AI era
| Dimension | Score | Why |
|---|---|---|
| AI helps or kills? | 3 | helps writers, but agents also make setup easy, so "ease" shrinks |
| Durability test | 4/5 | holds subscribers, payments, archive; owned relationship; leaving hurts; old need |
| Stable for 2 years | 4 | publishers needing their own audience is near-certain |
| Slow layer | 5 | sites with years of content won't move; meet them where they are |
Economics
| Dimension | Score | Why |
|---|---|---|
| Time to first dollar | 2 / 4 service-first | an ecosystem is a step curve |
| Time to signal | 3 | but you can test with your own customers in weeks |
| Revenue shape | 4 | annual licenses or subscriptions |
| Compounding | 4 | subscriber data, content, integrations, reputation |
| Residual value if it fails | 5 | a better theme, relationships, a plugin, knowledge |
Formula: Demand 4 × Hole 2 × Access 5 × Edge 4 × Durability 4. The weakest link is the hole, so test that first. (Chapter 9's scorer is preset to these numbers.)
Three hard truths#
- "Easy like Ghost + WordPress freedom" is a contradiction unless you choose a default path. Ghost is easy because it says no. Fix: one opinionated path (theme + setup wizard + newsletter + paywall + payments, pre-connected), with WordPress freedom as the escape hatch, not the front door.
- Don't fight for new writers. They'll choose Substack or beehiiv for zero setup and the network. The market is people already on WordPress with years of content who don't want to move.
- You need a hole Automattic won't fill. Their tools are generic and tied to Jetpack. Yours can be fully self-owned, no Jetpack, designed with the theme for small newsrooms.
The reshaped version#
- Segment: WordPress publishers losing Google traffic, starting with your own customers.
- Promise: "Turn your WordPress site into your own Substack. Keep your site, your content and your SEO, with no platform cut."
- Weeks 1–4: email customers and sell a done-for-you setup. First dollar, and you learn what actually hurts.
- Months 1–3: turn what repeats into one plugin.
- Months 3–12: only then grow toward the ecosystem.
- Kill criteria: "If fewer than 10 customers pay for setup or pre-order by week 6, there's no hole."
Takeaways
- Score every dimension, then look only at the lowest ones. The product is ruled by its weakest factor.
- Reshape the idea to lift the weak factors: narrower segment, service first, opinionated default.
- Write the kill number before you send the first email.
