The 0 to 10,000 Users Playbook for Startups
Watch on TikTok
Scaling a product to its first 10,000 users is a problem that looks different at every stage. Adam, who has scaled one product past a million users, breaks the journey into three distinct phases. Each one requires a different mindset, different channels, and a different level of spend.
Phase 1: 0 to 100 Users
Your first 10 users are people you know. You texted them about your launch, and they gave you honest feedback. The goal for this entire phase is to talk to every single user, preferably on a call.
For one of their products, Adam's team operated like an agency even though the long-term plan was a self-serve SaaS. They required every user to do a demo call before they could even access the product. This forced real conversations that revealed what worked, what did not, and what people actually needed.
This phase is also where you collect social proof. Get quotes, testimonials, and snippets you can use on your website. If it is genuinely hard to get anyone to use the product at this stage, that is a signal to consider pivoting.
Phase 2: 100 to 1,000 Users
This is where you start to understand whether your business can scale. Run lightweight ads on Google, Meta, or TikTok. Even a few dollars a day is enough. The point is to stress-test your funnel, not to acquire users at volume.
If 100 people visit your site and 10 sign up, how do you get that to 20? Then 30? This phase is about optimizing conversion rates, refining your messaging, and understanding your total addressable market more clearly.
Set up analytics with tools like Mixpanel or PostHog. You are no longer talking to every user individually, so the data needs to be clean and accessible.
Phase 3: 1,000 to 10,000 Users
By this point, you should have a solid product, features people want, a market you understand, and a funnel that converts cost-effectively. Now you increase volume.
If you were spending $5 a day on ads, push it to $100. If you were creating content yourself, hire influencers or UGC creators. If you were doing cold email, 10x the volume or hire someone to run it.
This phase is about pouring gasoline on the fire you already built. You can also start engineering viral moments and trying to "take over the timeline."
Why Each Phase Is Different
The deliberate progression matters. If you skip the 0-to-100 conversations, you build the wrong product. If you skip the 100-to-1,000 funnel optimization, you burn money at scale. Each phase produces knowledge that the next phase depends on.
Key Takeaways
- 0 to 100: Talk to every user. Do manual onboarding. Collect social proof. Consider pivoting if traction is absent.
- 100 to 1,000: Run small ads to stress-test your funnel. Optimize conversion rates. Set up analytics.
- 1,000 to 10,000: Increase spend, hire creators, scale cold outreach. This only works if the earlier phases were done right.
