Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cresta

  • Cresta depends on the CCaaS platforms it integrates with, and NICE, Genesys and Five9 are all shipping native real-time assist and auto-QA of their own, so at renewal you may be paying twice for capability your platform vendor will bundle at a discount.
  • Pricing is not published and contracts are seat-based and annual at enterprise scale, which in practice means six-figure commitments and a procurement cycle measured in months rather than weeks.
  • Real-time guidance only pays back where conversation outcomes are measurable and repeatable, so support teams handling long, varied, low-volume cases rarely recover the licence cost.
  • Deploying real-time assist requires agents to accept on-screen prompting mid-call, and contact centres with strong union representation or experienced tenured agents frequently see adoption resistance that no amount of model quality fixes.
  • Automated quality scoring changes what agents are measured on, and organisations that switch from human QA without rewriting their evaluation rubric and appeals process create industrial-relations problems that surface months after go-live.

Whereby

  • No breakout rooms, polls, or whiteboard tools
  • Hard cap of 200 participants and performance drops with groups of 12+
  • No phone dial-in option for participants without internet
  • Occasional connectivity issues and laggy screen sharing reported

Answered from the vendors’ own pages

Cresta: Does Cresta replace my contact centre platform?

No. It is designed to sit on top of NICE, Genesys, Five9, Amazon Connect and similar platforms, which is why it is chosen where a full CCaaS migration is not feasible.

Whereby: Does Whereby require software downloads?

No. Whereby is browser-based and requires no downloads or complex configuration. Participants join via a simple link without needing to install software.

Cresta: What does it cost?

Cresta does not publish pricing. Contracts are seat-based and annual, and at the enterprise scale it sells into they are typically six figures per year.

Whereby: What is Whereby's pricing model?

Whereby offers a free-forever plan and paid plans starting at $5.82/month when billed annually. Whereby does not offer a free trial.

Source
Cresta: Is it viable for a contact centre under 100 seats?

Rarely. The commercial model, implementation effort and required outcome measurement all assume several hundred seats or more.

It is an independent venture-backed company, having raised roughly 282 million USD in total including a 125 million USD Series D in November 2024 co-led by World Innovation Lab and the Qatar Investment Authority.
