Why do most AI freelancers disappear after delivery?

I’ve been speaking to a lot of small businesses before building Promptlancers, and one pattern kept coming up:

They try AI (chatbots, automation, marketing)…
But the experience is frustrating:

• The system works “okay” at first

• No real optimisation happens

• And the freelancer disappears after delivery

But AI systems aren’t “set and forget.”
They need monitoring, updates, and continuous tweaking to actually drive results.

That’s the gap we’re trying to solve with Promptlancers — combining AI experts with ongoing support and maintenance.

Curious to hear from others here:

-> Have you had a similar experience with freelancers or AI tools?
-> Do you think ongoing support should be standard?
