What Synthflow AI does
Runs AI voice agents that handle inbound and outbound phone calls, built in a visual flow designer on the vendor's own telephony.
Synthflow AI a voice AI platform aimed at enterprises that want to hand phone conversations to AI agents. Teams design agent logic in a visual Flow Designer, connect APIs, and can split complex tasks into subflows that act as specialized agents. Before launch, agents are checked with simulated calls in a Test Center, and once live, Auto-QA and monitoring review conversations.
The vendor runs its own telephony network and says it works with existing SIP or PBX setups, so a company can keep its current carriers. The platform also covers chat and SMS, not only voice, and lists more than 200 integrations across CRMs, contact-center systems, calendars and data tools. A Zapier connection lets agents start inbound and outbound calls from other apps. The homepage names SOC 2, HIPAA, PCI DSS and GDPR certifications.
Pricing is not self-serve. The pricing page shows a single Enterprise option with a Contact Sales button. It states contracts start at $30,000 annually, and the final figure is scoped around call volume, concurrency, telephony setup, integrations, security needs and launch support. The pages show no monthly price, no free plan and no trial. Implementation, onboarding, testing, training and launch support are listed as part of the Enterprise offering.

- Works with existing SIP or PBX setups and lists 200+ integrations

Our take
Synthflow fits larger organizations such as call centers, healthcare, insurance or telecom teams that have high call volumes, existing telephony or CRM systems, and a budget for an annual contract. It does not fit individuals, small teams or anyone who wants to try the tool cheaply first: the pages show a $30,000 annual starting point, a sales-led process, and no free plan or trial. Buyers should expect to scope the deal with the vendor before seeing a final price.
