Where Sierra is stronger
Voice at scale
Millions of calls a month, with continuity across channels. This is not Looper's playing field.
Federal compliance
FedRAMP High and HIPAA. If you sell to the US government, Sierra is set up for it.
Experimentation and control
A/B testing and experiment tools for a service agent are highly developed.
A smaller question mark
A CEO who led Salesforce and a budget of 1.6 billion dollars. There is little vendor risk.
Where Looper is stronger
Everything that is not a service call
Sierra does not build a sales report, invoice control, or payment reconciliation. Looper does.
Price known before you start
According to reports, Sierra does not publish pricing, and agreements start in six figures. Looper: fixed annual subscription, price discussed on the call.
Changes without a ticket
At Sierra, according to reviews, changing behavior goes through their team. At Looper, our team is part of the subscription and makes changes within hours.
Data stays home
SaaS versus running on your servers. For banks, healthcare, and government in Israel, this is the difference between a special agreement and the default.
Israeli systems
Priority, SAP B1, Hashavshevet, the bookkeeping Excel sheet. Sierra connects to Zendesk and Salesforce. Looper connects to whatever you have.
