Serval's initial approach used FDs to teach customers how to build on the platform, but the FDs often built the systems for customers instead.

“And so the first generation of this is we deployed all these FDs to explain to customers, "Okay, here's, here's how to build in the platform. Actually, let me just build it for you." And then realized it would be really nice if customers could just talk to an agent that understood their requirements and then translated that into the product primitives.”
