Why look for a Sierra alternative

Sierra is a US AI agent company whose voice agents answer and place customer service calls for businesses, alongside chat, messaging and email agents. Its honest limitations for an Indian SMB: outcome-based fees are not published, and its named customers are large brands; no Indian language named and no India office listed. If any of those matter to you, the alternatives below are worth a look.
