The hardest part of building SaaS is not building the product. It's knowing what to ignore.

When I started looking at SaaS products, I thought the hardest problems were technical.

Architecture.
Scaling.
Features.
Infrastructure.

But the longer I spend around founders, the more I think the harder problem is deciding what not to build.

Because every customer request sounds reasonable.

"Can you add this integration?"

"Can you make this workflow more flexible?"

"Can you add AI here?"

The dangerous part is that you can keep saying yes and still move backward.

A product can become more valuable for one user while becoming harder to understand for everyone else.

The best founders I see have a filtering mechanism:

Before building something, they ask:

Does this solve a repeated problem?
Does this make the core workflow easier?
Will this still matter 12 months from now?
Is this creating leverage or just adding maintenance?

Feature velocity feels like progress.

But sometimes the fastest-growing products are the ones that protect their simplicity.

Curious how other founders decide what not to build.
