From Zero to 100: The SaaS Founder's Playbook for Acquiring Your First Users
Posted on October 20, 2025 by Shourav Rahman
The Silent Killer of Early-Stage Startups: A Perfect Product with No Users
As a SaaS founder, you're a builder at heart. The temptation to add just one more feature, polish the UI, or refactor the backend is immense. But a flawless product without users is a ghost town—a testament to effort without impact. The journey to your first 100 users is the most critical validation stage of your startup. It's where your idea confronts reality and begins its transformation into a real business.
Step 1: Laser-Focus on Your Ideal Customer Profile (ICP)
"Everyone" is not your customer. To find your first 100 users, you need to know exactly who you're looking for. An ICP is a detailed portrait of the person who feels the pain you're solving most acutely.
- Demographics are just the start: Go beyond job titles and company sizes. What are their daily frustrations? What tools are they currently using (and hating)?
- Find their digital watering holes: Where do they congregate online? Is it a specific subreddit like r/saas, a niche Slack community, or a particular hashtag on Twitter? Be a fly on the wall before you're a participant.
Step 2: The Art of the Unscalable: Manual Outreach and Community Engagement
Forget automated marketing funnels for now. Your first 100 users require a personal touch.
- The Feedback-First Outreach: Identify 20-30 people who perfectly match your ICP. Send them a personalized message on LinkedIn or via email. Don't pitch your product. Instead, ask for their expertise. Frame it as, "You're an expert in this space, and I'd love to get your feedback on something I'm building to solve [specific problem]."
- Become a Community Fixture: In the online communities you've identified, become a valuable member. Answer questions, share your expertise, and build relationships. Only mention your product when it's a genuine and helpful solution to a problem being discussed. This builds trust and social proof.
Step 3: The Concierge Onboarding Experience
Paul Graham's famous essay, "Do Things That Don't Scale," is your bible at this stage. You need to create an onboarding experience that is so good, your first users will never forget it.
- White-Glove Treatment: Personally onboard every single user. Schedule a 1-on-1 video call. Walk them through the product, help them set up their account, and show them how to achieve their first "aha!" moment.
- Listen with Intent: Your first users are a goldmine of feedback. They will show you where your UI is confusing, where your value proposition is unclear, and what features are missing. This feedback is the raw material for achieving product-market fit.
