Synthflow is an AI voice agent platform for mid-market and enterprise teams that automate customer phone calls. Each deployment is scoped into one annual agreement covering telephony, integrations, security review and launch support, with white-label options for BPOs. - **Category:** AI Agents - **Made by:** Synthflow AI - **Website:** https://synthflow.ai - **Runs on:** Web - **Who should skip it:** Not for you if you want to try it, as the page says no free plan and no trial. - **Facts last checked:** Nov 12, 2026 ## Pricing Synthflow's current pricing could not be confirmed from its own site. ## Key features - **Voice agents for calls:** Agents handle customer service, reception, answering service, concierge, appointment booking and IVR use cases over the phone. - **Telephony options:** The contract can use Synthflow Native Telephony, SIP trunking or approved enterprise telephony, with routing, escalation and fallback logic. - **White label:** BPOs and software platforms can run it under their own brand, with a workspace per client and one analytics dashboard across them. - **Launch support:** Where the agreement includes it, Synthflow's forward-deployed engineers implement, test and launch agents with your team. Deployments go live in weeks. - **Security and compliance:** The Trust Center lists SOC 2 Type 2, ISO 27001, GDPR, HIPAA (self-attested) and PCI DSS v4.0.1, with ISO 42001, DORA and the EU AI Act in progress. ## Good for - Mid-market and enterprise teams automating inbound customer calls - BPOs and software platforms that need white-label voice agents for clients ## Worth knowing - No prices are published. The pricing page says it is an annual enterprise agreement with no free plan, no trial and no per-minute rate. - Every new deployment starts on an Enterprise contract, so it is not set up for self-serve small-business use. - HIPAA is listed as self-attested in the vendor's own Trust Center summary. ## ToolGPA grades **GPA: 1.8 out of 4**, graded Nov 12, 2026.

The category's chart of price against score: https://toolgpa.com/charts/ai-agents ## Keep it, or make your own? **Keep it.** To replace Synthflow you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 76 of the 101 other AI agents grade higher. - You could not: An AI agent, with the models and the safeguards behind it. - You could not: Phone numbers and calls carried over the phone network. - You could not: It plugs into other products, Cal.com, Five9 and Zoom among them, and has an API. - You could not: What a company asks for before it lets staff use something: SOC 2 and HIPAA.
