The Upwork Alternative Built for RAG Development
Hire skilled RAG engineers with transparent deliverables — and skip the connects, the bidding wars and the buyer fees. Buyers pay the price they see; creators keep more, with 0% on the first $500 and zero payout fees.
Why people look for an Upwork alternative for RAG development
Hiring an engineer to build retrieval-augmented generation and vector search 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 RAG development work.
Bidding wars
Open bidding drives a race to the bottom, not the best RAG 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 RAG pipeline moving.
Hard to vet real skill
Generic profiles make it tough to tell a genuine RAG and vector-search engineer from a generalist.
Limited payment options
Card-only checkout shuts out clients who'd rather pay in crypto.
