Aya Healthcare vs Vivian Health: Agency vs Marketplace, and Why It's Not Either/Or

Nurses type "Aya vs Vivian" into search bars every day, and the honest first answer is that the question contains a category error. Aya Healthcare is a staffing agency — an employer that hires you, pays you, and holds the contract with the hospital. Vivian Health is a marketplace — a storefront that aggregates jobs from many agencies (and some direct employers) and connects you to recruiters. One is a store; the other is the mall directory. You don't have to choose between them, and the sharpest travel nurses in 2026 use both at once. Here's how each actually works, where each earns its keep, and the workflow that extracts the most value from the pair.

What Aya actually is

Aya is one of the largest healthcare staffing agencies in the country. When you take an Aya contract, Aya is your W-2 employer: it bills the hospital an hourly rate for your labor, and out of that bill rate it pays your taxable hourly, your tax-free stipends (if you qualify with a legitimate tax home — see 1099 vs W-2 for travel nurses and the housing stipend guide), your benefits, and its own margin. Scale is Aya's core advantage: a very large job board of its own, exclusive or priority relationships with some large health systems, credentialing infrastructure that can move fast, and benefits continuity if you string contracts back-to-back. The tradeoff of scale is variance — your experience is heavily shaped by which recruiter you land, and pay packages on identical jobs can differ between agencies staffing the same unit, which is exactly the opacity a marketplace exists to attack.

What Vivian actually is

Vivian doesn't employ nurses and can't offer you a contract. It aggregates postings from many agencies, normalizes them into comparable pay estimates, and lets you see — before ever talking to a recruiter — roughly what the market is paying for your specialty in a given city. Its revenue comes from agencies paying for access to candidates, which is worth keeping in mind: the jobs you see are from participating agencies, not a census of every contract in existence. Vivian's killer feature is pay transparency as negotiating leverage: when you can screenshot three comparable postings, "that's below market" stops being a feeling and becomes a document. We cover the platform in depth in the full Vivian Health review.

Side by side (once you know it's not a fair fight)

The workflow that uses both

1. Scout on Vivian. Set your specialty and target regions, watch posted ranges for two or three weeks, and learn what "good" looks like before anyone is selling to you.
2. Collect comparables. Save two or three postings for similar units and shifts. These are your negotiation exhibits.
3. Talk to two or three agencies — Aya among them if its job list fits your targets. Multiple recruiters means multiple bids on you.
4. Make packages comparable before comparing offers: taxable hourly, stipends, guaranteed hours, cancellation terms, overtime rate. The blended-rate math is in pay packages explained.
5. Negotiate with receipts. A specific comparable beats a vague ask. Word-for-word language lives in the salary negotiation guide.

Where each one bites

Vivian's estimates are estimates — a posting's headline number can assume stipend eligibility you don't have, or hours you won't be guaranteed, so never treat a listing as an offer. Aya's size cuts both ways: fast credentialing and deep job flow, but you are one of thousands of travelers, and contract terms (especially guaranteed hours and cancellation clauses) deserve line-by-line reading no matter how friendly the recruiter. If you're weighing the gig-app model instead of agencies entirely, that's a different comparison — see Clipboard Health vs traditional agencies.
