Introduction: Why Integrations Matter
In the modern software landscape, no product exists in isolation. Your users likely use dozens of tools, and they want your product to play nice with the rest of their stack.
Integrations aren’t just a nice-to-have feature—they’re often a deciding factor in purchase decisions. A product with great integrations can win over a competitor with more features.
In this guide, we’ll cover how to think about integrations strategically and build an integration ecosystem that drives growth.
Why Integrations Matter

Factors to consider:
