What Is Synthflow AI?
Synthflow is a no-code, drag-and-drop platform for building AI voice agents, founded in 2023 and headquartered in Berlin, having raised a $20 million Series A in 2025 — popular with agencies and used by many small businesses as an AI receptionist. Pricing has evolved significantly: while older reviews still quote retired $29-$899 monthly tiers, the current model charges per successful call minute at typical effective rates of $0.15-$0.24/minute on pay-as-you-go, plus actual AI usage costs adding roughly $0.07-$0.16/minute — enterprise contracts start at $30,000/year. As of 2026, Synthflow is voice-only.
A genuinely important real-cost detail worth understanding: the per-minute rate depends on your specific model, voice, and telephony choices, and importantly, the advertised per-minute rates don't include actual AI usage costs, which add a separate $0.07-$0.16/minute on top — anyone budgeting for Synthflow should combine both figures (base rate plus AI usage) to estimate real total per-minute cost rather than relying on either number alone.
It's aimed at agencies and small businesses wanting no-code AI voice receptionist agents, with the important caveat that the pricing model transitioned from flat monthly tiers to pay-as-you-go per-minute billing — anyone researching Synthflow pricing should be aware that older reviews referencing the retired $29-$899 monthly tiers no longer reflect current pricing, and should budget using the combined per-minute rate (base plus AI usage costs) instead.
