Decision Tree
1. Do you have a product?
No, just an idea → Start with Idea OS
- Validate if it's worth building
- Understand the market
- Make a go/no-go decision
No, but I'm ready to build → Choose your starting point:
- SaaS Dev Team for web apps
- Marketing OS
/landing-pagefor landing pages
Yes, I have a product → Continue to question 2
2. Do you have users?
No users yet → Marketing OS (soft launch mode)
- Manual outreach
- Content marketing basics
- Find your first 100 users
Yes, I have users → Continue to question 3
3. Do users activate?
Activation = users experience your core value (not just sign up)
Most users leave before activating → PMF OS
- This is an activation problem
- Diagnose why users don't reach your "aha" moment
- Find patterns in the users who do activate
Users do activate → Continue to question 4
4. Do activated users come back?
Users leave after activating → Success OS
- This is a retention problem
- Identify at-risk users
- Build engagement campaigns
Users stick around → You likely have PMF! → Marketing OS (scale mode)
- Scale user acquisition
- Paid ads, aggressive SEO
- Viral loops
Common Scenarios
"I have a product but no PMF"
Wrong approach: Jump to Marketing OS for more users
Right approach:
- PMF OS
/diagnose— understand WHY users leave - PMF OS
/interview— talk to churned users - PMF OS
/patterns— find what retained users have in common - Fix product based on insights
- Then Marketing OS for growth
Getting more users won't help if your product doesn't retain them.
"I want to improve my landing page"
Ask yourself: Do I have product-market fit?
If NO PMF:
- Start with PMF OS — understand positioning first
- Learn what language users use, what resonates
- Then update landing page with those insights
If YES PMF:
- Marketing OS for conversion optimization
- Use
/landing-pagecommand if building from scratch
Optimizing a landing page for a product that doesn't have PMF is polishing a broken offering.
"Users sign up but leave after day 1"
This is an activation problem, not a retention problem.
Use: PMF OS
/diagnose— find the root cause/activation— analyze activation funnel/patterns— what do activated users do differently?
Don't use: Success OS — that's for post-activation retention.
"I validated my idea, now what?"
The typical journey:
- Build your product (use SaaS Dev Team if applicable)
- Launch to first users (Marketing OS, soft launch mode)
- Analyze why users stay/leave (PMF OS)
- Iterate until PMF
- Scale (Marketing OS, scale mode)
- Retain (Success OS)
