AI adoption is shifting toward tailored solutions as enterprises look for tools that solve domain-specific problems.
Off-the-shelf platforms often fall short when real-world operations, compliance, and integration complexity come into play. More companies are choosing to build custom systems that align with their data, processes, and long-term goals.
This shift is especially clear in sectors like healthcare, finance, manufacturing, and logistics, industries with complex requirements and little room for error.
