Why teams switch

Why ecommerce brands choose Yuma over Siena

What changes when the AI resolves the ticket, not just the first reply.

  1. 01AUTOMATION

    Up to 89% automation for named brands

    Siena says its agents automate up to 80% of tickets. Yuma's results are public and named: EvryJewels automates 89% of tickets across 150k+, Petlibro 79% and MFI Medical 64%, each in a published case study.

    • EvryJewels: 89%
    • Petlibro: 79%
    • MFI Medical: 64%
  2. 02PRICING

    Pay for resolved tickets, not attempted conversations

    Siena lists a $750 monthly platform fee plus $0.90 per ticket, and bills per conversation whether or not it was resolved. Yuma charges only when a ticket is fully resolved: the price depends on your volume, the median is $0.74, and there's no platform fee.

    • Billed only for fully resolved tickets
    • No platform fee, no per-agent cost
    • Every billed ticket listed with the reason
  3. 03ROI

    Results in your first week, instead of months

    Yuma goes live within a week on a share of real tickets, so you see quality before you scale. A 100% ROI guarantee means you pay nothing if the savings don't outweigh the fee, and Clove reached 3x ROI in 3 months.

Customers

Why ecommerce leaders switched to Yuma

  • Before Yuma, we were drowning in a sea of over 10,000 tickets, and our first response time was a staggering 1 week. Other AI solutions we tried were unreliable, hallucinating, and didn't align with our guidelines.

    • 63%Lower cost
    Read case study
  • We barely had to think about the technical side. Yuma just worked, right out of the box. That was a huge relief, so we could focus on customer experience rather than implementation.

FAQ

Frequently asked questions

Why do ecommerce brands switch from Siena to Yuma AI?

The reasons that come up most are pricing and time to value. Siena bills per conversation whether or not the ticket was resolved; Yuma charges only for tickets fully resolved end to end. Yuma goes live within a week and works inside the helpdesk you already use, backed by a 100% ROI guarantee.

How does Siena's pricing compare to Yuma?

Siena lists a $750 monthly platform fee plus $0.90 per ticket, and counts a conversation as billable whether it was resolved or handed back to a human. Yuma charges only for fully resolved tickets. The price per resolution depends on your volume, and the median across customers is $0.74. There's no platform fee and no per-agent cost.

Is Yuma a replacement for my helpdesk?

No. Yuma isn't a helpdesk; it's the AI layer for ecommerce brands. It works inside Gorgias, Zendesk, Kustomer, Re:amaze, Gladly, Salesforce and more, so your queues, macros and routing stay as they are.

How long does it take to go live with Yuma?

Within a week. Yuma connects to your helpdesk and reuses your existing macros and knowledge base, then starts on a share of live tickets so you can check quality before scaling.

What if we're not on Shopify?

Yuma works with Shopify, WooCommerce, Magento and custom backends. Siena's published ecommerce integrations are Shopify and Fulfil.

What is Yuma's Safety Guard, and does Siena have an equivalent?

Safety Guard is Yuma's built-in hallucination prevention. Every AI response is checked for accuracy, policy compliance and confidence before it reaches a customer, and low-confidence replies go to a human with full context. Siena publishes guardrails and granular controls for its agents.

Can I try Yuma on my real tickets before committing?

Yes. Yuma offers a 30-day free pilot on real tickets, starting on a share of your volume so you can review quality before you scale.

Can I switch from Siena to Yuma without changing my helpdesk?

Yes. Yuma works inside Gorgias, Zendesk, Kustomer, Gladly and other helpdesks, so you don't need to change your helpdesk, migrate tickets or retrain agents.
