Building a Saas at night after my full-time job and putting 3 kids to bed

Hi everyone,

I'm a father of 3 kiddos, work a full-time job, and for the last few months i've been spending my evenings building a SaaS for marketing agencies.

The idea came from seeing how much agencies spend creating proposals and quotes, many are still copying old documents, editing PDFs, and rewriting the same information over and over. Even in the era of AI manual work still a must.

I started building an MVP that can generate agency proposals in minutes by reusing agency information, services, pricing, and proposal templates.

The reality is that progress has been slower than i expected. Some nights i get 1 to 2 productive hours. Some nights a kid gets ill, work get busy, or i'm simply too exhausted to continue the project.

I've reached the stage where i have a working MVP, but now facing what feels like the hardest part: getting real users and honest feedback.

I'd love feedback from other founders on:

1. How did you get your first 10 beta users?

2. What acquisition channel worked best when you had almost no budget?

3. Looking back, what mistake dud you make when validating your SaaS?

Sometimes it feels like everyone is shipping faster than me, but i'm trying to stay consistent and make progress one evening at a time.

Thanks for reading, and i'd appreciate any advice from founders who've been through this stage.

** If anyone wants to see the MVP and give brutally honest feedback, i'm happy to share the link in the comments. **
