Lessons from Building Multiple SaaS Products

Over the past few years, we've built and launched several SaaS products at EXLAC. Here are the key lessons we've learned along the way.

Start with the Problem, Not the Solution

It's tempting to start with a cool technology or feature idea. But the most successful products we've built started with a clear understanding of a real problem that people face.

Architecture Matters (But Don't Over-Engineer)

**Choose boring technology** for core infrastructure. We use:

  • Next.js for frontend
  • Cloudflare Workers for edge computing
  • PostgreSQL for data storage
  • Redis for caching
  • The key is finding the right balance between scalability and simplicity.

    User Feedback is Gold

    We've learned to:

  • Ship early and iterate based on feedback
  • Talk to users directly (not just through surveys)
  • Watch how users actually use the product
  • Prioritize feedback from paying customers
  • Pricing is Part of the Product

    Don't leave pricing as an afterthought. We've found that:

  • Simple pricing converts better
  • Free tiers should be genuinely useful
  • Value-based pricing works better than cost-plus
  • The Team Makes the Difference

    A small team of motivated people can outperform a large team that's just going through the motions. We focus on:

  • Hiring for attitude and aptitude
  • Giving ownership, not just tasks
  • Celebrating wins together
  • Conclusion

    Building SaaS products is a marathon, not a sprint. The companies that succeed are those that stay focused on solving real problems while maintaining the agility to adapt as they learn.
