Synthflow is a genuinely well-reviewed voice-agent platform — 4.5 out of 5 on G2. The difference isn’t quality, it’s what you’re buying: Synthflow sells infrastructure (enterprise contracts from $30,000 a year, scoped to volume and integrations), and the agents’ behavior is your configuration. We sell an outcome — booked meetings — with compliance enforced in code and a flat published price.

| BoringSales | Synthflow | |
|---|---|---|
| What you’re buying | A done-for-you AI setter: every inbound lead called in about a minute, qualified, booked, and reminded so they actually show. | A voice-AI agent platform, well reviewed at 4.5/5 on G2.[2] |
| Who builds & tunes the agent | We do. Every AI is battle-tested with tough test calls before it dials a real lead. | Built on the platform for your use case; enterprise engagements include implementation and onboarding support.[1] |
| AI disclosure on calls | The AI says it’s an AI and that the call is recorded, at the top of every call — a deterministic greeting gate enforced in code, not a prompt suggestion. | Not publicly documented. |
| Opt-out handling | One texted STOP — or ALTO — suppresses that person across every channel, SMS and voice, English and Spanish. Deterministic matching, never AI judgment. | Not publicly documented. |
| Cold-call consent | Cold outbound requires express written consent on file. The dial gate fails closed: no proof, no dial. Canadian (CASL) numbers are never dialed at all. | Not publicly documented. |
| Quiet hours | Every consumer touch is clamped to the 8 a.m.–9 p.m. federal TCPA floor in the lead’s local time — and fails closed when the timezone is unknown. | Not publicly documented. |
| Call quality control | A second AI grades 100% of calls for compliance and quality. Quoting a price or claiming to be human is an automatic fail. | Not publicly documented. |
| Your data | Yours. Full export any time, and your do-not-call list survives churn — opt-outs stay honored even after you leave. | Not publicly documented. |
| Pricing | $2,000/mo flat · 1,000 call-minutes included · $1.00/min after. | “Enterprise contracts start at $30,000 annually” — final pricing scoped to call volume, concurrency, telephony, integrations, and launch support.[1] |
| Guarantee | 20 booked meetings in your first month, or you don’t pay. | Not publicly documented. |
