SaaS (Software as a Service) has become one of the most popular models for launching a tech business. Accessible, scalable, with recurring revenues, it attracts ambitious startups as well as solopreneurs.

But launching a SaaS is not just a matter of code: it is above all a structured approach that combines product strategy, marketing and market understanding.

1. Validate the idea before coding

The first mistake SaaS creators make is to go headlong into development. The right approach:

• Identify a specific pain in the market,
• Exchange with future users,
• Test the willingness to pay,
• Create a “paper” version (mockup, landing page) to validate interest.

2. Building an MVP (Minimum Viable Product)

The objective: to offer a first version that is simple but functional. You don't need all the features from the start, but enough to address the problem identified.

👉 Example: Notion started as a simple note-taking tool before becoming a complete platform.

3. Choosing the right business model

SaaS is often based on a subscription (monthly or annual). Key points to decide:

• Price positioning (low, medium or premium),
• Free offer or trial period,
• Upsells (advanced features, integrations).

4. Finding your first customers

• Online communities (Reddit, Product Hunt, LinkedIn),
• Existing network (prospects already identified),
• Content marketing (blog, SEO, videos),
• Partnerships with other tools.

5. Evolve the product

Once the first customers are onboarded:

• Gather their feedback,
• Prioritize improvements,
• Set up responsive support,
• Work on scalability (technical and business).

Conclusion

In 2025, SaaS remains a model for the future, but success does not only depend on code: it is based on understanding the market, listening to customers and commercial discipline.

💡 Practical tip: don't code a line until you've talked to at least 20 potential customers.
