About Synthflow

Synthflow builds AI voice agents that answer and place phone calls — inbound support, outbound qualification, appointment booking — and it has moved firmly up-market. Its pricing page (read 16 October 2026) lists a single Enterprise plan: contracts start at $30,000 a year, with the final price set by call volume, concurrency, telephony, integrations, security needs and launch support. Telephony can run on Synthflow's own numbers, your SIP trunk or approved enterprise telephony; concurrency is planned per contract; and the page shows SOC 2, HIPAA, GDPR and ISO 27001 badges, EU and US hosting, and support for MSA and DPA paperwork and enterprise security reviews. It lists no per-minute rate, no included minutes and no free trial, so the $29-a-month self-serve plan this directory used to show has been removed. What that means: Synthflow is now a contract purchase for contact centres and businesses with steady call volume, not something a small business can switch on for an afternoon. The limits: the $30,000 floor; voice quality and response speed that you can only judge on a pilot with your own callers; and the consent and recording rules that apply to automated calls wherever your callers are. Intercom Fin and Zendesk AI on this site handle chat and email first, and Tidio suits small businesses whose customers write rather than call. Verdict: shortlist it for high-volume phone operations that need compliance paperwork and a choice of hosting region; everyone else should start with a chat agent.
