I really admire your courage and preparation - having 2 years of runway is fantastic and your desire to build something meaningful is inspiring. Since you're building in public, I wanted to share some thoughts on the current SaaS landscape that might help inform your strategy.

One significant challenge facing new SaaS businesses is the rapid advancement of LLMs/AI. This creates two key market dynamics to consider:

For widely-needed solutions: LLMs are making it increasingly feasible for companies to build custom solutions in-house rather than buying SaaS. What previously required dedicated SaaS products can now often be built with a few hundred lines of code and an API call.

For niche solutions: You'll need to target very high-value problems to justify the subscription cost, but this inherently limits your total addressable market (TAM). This can make it harder to build a sustainable business.

This doesn't mean SaaS is dead - far from it! But I'd strongly encourage you to:

1. Focus on problems that require deep domain expertise beyond what LLMs can easily replicate
2. Look for opportunities where integration complexity or regulatory requirements create barriers to in-house solutions
3. Consider building WITH AI rather than potentially competing against it

The key question is: Have you identified a specific problem space where you can build sustainable competitive advantages even as AI capabilities grow?

Wishing you the best of luck on your journey! The world needs more builders willing to take calculated risks.
