Why people look for an Upwork alternative for AI agent development
Hiring an engineer to build autonomous and multi-agent systems shouldn't mean paying to bid and racing competitors to the bottom. Here's where the old model gets in the way.
Connects cost to bid
Paying for connects just to send a proposal adds up before you've won any AI agent work.
Bidding wars
Open bidding drives a race to the bottom, not the best AI agent engineer for the job.
Payout charges on top
Withdrawal fees stack on top of the platform's cut, shrinking what engineers take home.
Slow, heavy hiring
Long proposal threads and interviews delay getting your AI agent build moving.
Hard to vet real skill
Generic profiles make it tough to tell a genuine agent and LLM engineer from a generalist.
Limited payment options
Card-only checkout shuts out clients who'd rather pay in crypto.
