From 0 to 400+ Customers: SaaS Growth Hacks from a Serial Founder

Meet Ricardo - he has successfully launched multiple SaaS products, turning his ideas into revenue-generating apps. If you’re looking to build and launch your own product efficiently, we’re about to share some of Ricardo’s key strategies.

He’s a developer with a background in telecom engineering, having held leadership roles at companies like Vodafone and Glovo. But after years of putting fires out in management, he returned to hands-on development, focusing on building apps that solve real problems—fast.

By leveraging Open SaaS, Ricardo was able to ship multiple projects quickly, skipping the usual headaches of setting up authentication, payments, and other things every SaaS needs. In this post, you’ll discover what types of SaaS products he launched and the strategies he used to get them off the ground.

Why Ricardo Chose Open SaaS

When searching for frameworks to kickstart his projects, Ricardo stumbled upon Open SaaS, a 100% free, open-source starter for React & Node.js. and. He was drawn to Open SaaS because of its simplicity, community, and modern tech stack. He also liked the fact that the company had Y Combinator seal of approval.

“The fact that Wasp is low-friction and uses a great stack like Prisma, React, Node.js, and TypeScript—made it stand out. Plus, the community is super helpful. You can get started fast without spending hours on setup.”

What Ricardo loves most:

  • Pre-built Features: Open SaaS relies on Wasp - a full stack framework for React, Node.js and Prisma. The way Wasp handles routes and authentication was a game-changer.

“Just putting routes in main.wasp makes everything super simple. Auth works seamlessly, too.”

  • Focus on Building: By handling repetitive setup tasks like setting up payment integrations or making admin dashboards, Open SaaS allowed Ricardo to focus on core features.
  • Adaptability: regardless of the idea he had - a full-fledged SaaS, or a Google add-on which needed a robust-backend and a dashboard, he was able to build the app with Open SaaS boilerplate starter.

“I didn’t feel limited by the boilerplate—it’s flexible and gets out of the way.”

Ricardo started a few projects with Wasp, while working on the third one he started before discovering Open SaaS.

Meeting Reminders

  • Bult in less than 7 days.
  • 400+ paying customers.

This tool is a Google Workspace add-on that reduces no-shows by automating pre-meeting reminders. His competitive edge is that he covers WhatsApp alongside SMS and email reminders. Meeting Reminders app shows how versatile Open SaaS boilerplate is, because it can handle edge cases like this one and integrate into Google’s system.

Calls being skipped was a huge pain for Ricardo when he was working at a VC company. His day would include a lot of calls, and the cancellation rate was high. Once he started emailing participants before the call, the number of cancellations reduced significantly. Some time later, he built the tool himself to automate this 😃

Meeting Reminders

In this case, Open SaaS handles backend tasks like subscription checks and authentication. Because of that, this is a lightweight app that solves a niche problem effectively, and doesn’t require a lot of maintenance.

The first users were people he knew personally, and he did a bit of promotion on targeted groups on Slack and Discord. Since it’s a Google Marketplace app, anyone looking for Meeting Reminder add-on will have a chance to see it.

He also relies on SEO, and guess what, he pushed a couple of blog posts with his first SaaS, AI Article Generator. As he said before, you should make tools that scratch your itch first. 😃
