Part 5: What to Do After Launch

Grow your product like a real SaaS founder

✅ What you’ll do now

You built and launched a working product.
Now learn what to add next  and how to get your first 100 users.

You’ll learn:

• Terms that’ll come up as your app grows

• Tools that help you run and improve your product

• APIs you can use to add power to your app

• Simple ways to start getting users today

Common Terms You’ll Hear

You don’t need to master these.
You’ll start seeing them in docs, videos, and prompts.

You already used some of these via AI builders.
They matter more when you go custom.

Tools That Power Real SaaS Products

These tools help you run your product like a real business.
They are used to manage payments, users, communication, and growth.

Most of these come in later after you’ve found users.
You don’t need them all today. Save this list.

APIs That Add Features to Your App

Want your app to do more?
Use APIs. They add extra power, without needing you to code.

Use these when:

• You want AI features in your app

• You want your app to post content

• You want it to pull in data from somewhere else

If you’re not ready, skip it for now.
You’ll reach for them when the product demands it.

How to Get Your First 100 Users

Here are 20 fast ways SaaS founders get their first users.

You don’t need ads. You need conversations.

1. Share your app in 2 Discord groups where your users hang out

2. DM 5 people asking for feedback, not signups

3. Post a screen recording showing what the app does

4. Add your app link to your Twitter, IG, and LinkedIn bios

5. Share the problem it solves - not the features

6. Ask people: “Would this be useful to you?”

7. Comment on other creators’ posts with value, not links

8. Join one relevant Slack or Telegram group and show up

9. Share the 3 features your app solves in a tweet thread

10. Use Loom to record a 60-second walkthrough

11. Write a 3-line Reddit post about what you built and why

12. Post a screenshot with: “Built this in 48hrs with AI. Try it?”

13. Join Indie Hackers and publish a short “Launch Log”

14. Email 10 people with: “I made something you might find useful”

15. Use MarketingBlocks to post daily expert content (already running)

16. Give away 3 free lifetime accounts to active users

17. Share a niche checklist as a lead magnet

18. Join one Twitter/X space or live session in your niche

19. Talk to 1 user on a Zoom call and ask what confused them

20. Repeat what works every week
    

Focus on this:

• Be helpful

• Be consistent

• Ask questions

• Share the journey

5 users who care are more valuable than 500 who bounce

What to Do Now

1. Save the tools and APIs you’ll need later

2. Pick 3 actions from the user list
