The future of integration infrastructure in B2B tech stacks is expected to be vastly different from today's complex and fragmented SaaS stacks. To unlock the full value of SaaS, software companies need to develop integration infrastructure that abstracts away challenges of creating custom integrations at scale. Current solutions like Embedded IPaaS and Unified APIs have limitations that prevent them from delivering seamless connections, flexibility, and scalability. However, a new integration layer leveraging AI is being developed to simplify and speed up the process of building deep integrations, enabling developers to create agnostic integrations and unlock the full potential of SaaS apps. This infrastructure will change the game for product leaders, extending the value of their SaaS apps and driving network effects for buyers, ultimately making integration a key differentiator in the competitive marketplace.
