AI has already settled into everyday business operations, powering chatbots in customer support, speeding up data analysis in finance, helping HR screen candidates, and more.
But not all AI tools are created equal. Some companies rely on pre-built solutions, and they work effectively for standard tasks. However, off-the-shelf AI follows predefined workflows, which may not suit organizations with unique processes or strict compliance requirements.
That’s why companies are choosing to build custom AI agent platforms so they don’t have to align their workflows to fit pre-made tools.
If you’re considering creating an AI solution that can adjust to your workflows rather than forcing you to align with theirs, this article is for you. Below, we explore the best companies building custom AI agent platforms.
