Why is decision-making still so difficult in B2B companies?

As companies grow, they adopt more tools—CRMs, marketing platforms, finance software, customer support systems, analytics, and more. Each one generates valuable data, but that data usually lives in isolation.

I've realized that many leaders struggle because they have too much of that, spread out across too many places. Before making a decision, they often have to gather reports, reconcile numbers, and understand how one department affects another.

In your experience, what's the biggest obstacle to making fast, confident decisions in a growing B2B company?

Is it data quality, disconnected tools, too many dashboards, lack of context, or something else? I'd love to hear how other founders and operators are dealing with this.
