SaaS (Software as a Service) is one of the most popular models in the startup world today. Why? Because it makes it possible to generate recurring revenue, to scale quickly and to address a global market.

But be careful: launching a SaaS is not just about coding an application. It is a complete project that combines technical, business and marketing.

1. Finding a really useful idea

A SaaS must solve a concrete problem. Classic mistakes:

• Launch a product without validating the need,
• Targeting a market that is too large,
• Copying a competitor with no added value.

👉 Advice: ask your network, talk to your future customers and build an MVP (minimum viable product) quickly.

2. Define a solid business model

SaaS is based on subscription. But you still have to choose:

• Freemium or paid from the start,
• Monthly, annual or usage-based billing,
• Scalable pricing strategy.

👉 Klark chose a paid model from the start, to build strong perceived value and a sustainable business.

3. Develop a simple but functional product

The trap? Wanting to develop too many features from the start.

• Start with a Clear and useful MVP,
• Tested with a small panel of customers,
• Continuously improve based on feedback.

4. Building an adapted marketing strategy

SaaS without marketing is doomed to disappear.

• Develop some SEO content (articles, guides, comparisons),
• Put in place Paid Marketing (Google Ads, LinkedIn Ads),
• Anime one fellowship around your product.

5. Manage customer support and loyalty

A satisfied subscriber is a subscriber who stays.

• Respond quickly to support tickets,
• Set up a smooth onboarding,
• Create a public roadmap to involve your users.

6. The pitfalls to avoid

• Underestimating customer acquisition costs (CAC),
• Not securing data and compliance (RGPD, cloud security),
• Wanting to scale too early without having a controlled churn.

Conclusion

Launching a SaaS is an exciting but demanding adventure. By validating your idea, simplifying your product, working on your marketing and taking care of your customers, you increase your chances of building a lasting solution.

💡 Practical tip: Start small, iterate quickly, and always keep an eye on your cash flow.
