What our research says

Freeday

One of the few vendors in this category that actually prices on results rather than seats, which shifts the risk of a badly performing agent back onto them. It is an enterprise sale end to end: no trial, no price, and no way to evaluate it without booking time with their team.

Pros

  • Pay-per-resolution contracts instead of per-seat licences
  • Voice, chat, email and WhatsApp handled through one platform
  • Named integrations with Salesforce, SAP, Epic and Zendesk
  • ISO 27001 and NEN 7510:2024 certified, which matters for Dutch healthcare and finance
  • Implementation and 24/7 support are stated as included in the rate

Cons

  • No published pricing, so no way to size a deal without a sales call
  • No self-serve signup or trial
  • Automation rate guarantees are vendor-stated and not independently verified

Sierra

Sierra is the enterprise end of the support-agent market: the pitch is not a chatbot but an agent that can actually change an order or a policy inside your systems, priced on what it resolves. The customer list and the certification wall are real signals that large regulated companies have put it in front of their users. It is a procurement, not a purchase - no public price, no trial, and an integration project before anything goes live - so a company without a sizeable support operation has nothing to buy here.

Pros

  • Agents take actions in order, billing and account systems, not just answer questions
  • One agent runs across chat, SMS, WhatsApp, email, voice and ChatGPT
  • Outcome-based pricing aligns the bill with resolutions
  • Ghostwriter drafts agents from existing SOPs and transcripts, and the founders' track record is unusually strong

Cons

  • No public pricing, trial or self-serve path
  • Outcome pricing needs a contract definition of 'resolved' that favours neither side - read it closely
  • Integration with core systems is a project with real lead time
  • Vendor lock-in is high once customer memory and policies live in its context engine
