Embed Workflow (https://embedworkflow.com). Embeddable workflow builder for SaaS platforms. Your users design and run their own workflows inside your product.

5+ years now, bootstrapped. I still write most of the code. The product itself isn't AI, it's orchestration. Visual builder, triggers, delays, webhooks, execution logic. Some of our users do wire up AI models or agents through it, but the core is just helping non-technical people build automations for our clients product.
