Heavano vs Synthflow
Synthflow now sells through enterprise contracts. Heavano is self-serve: sign up, get free credit and start taking calls today, then pay per second of call time — with an Enterprise plan when you need dedicated support.
About Synthflow
Synthflow is a voice AI platform whose pricing page lists a single Enterprise plan, with contracts starting at $30,000 a year. Pricing is set per contract based on call volume, concurrency, telephony, integrations and security needs. The page does not list a self-serve plan, per-minute rate or free trial.

Choose Heavano if…
- You want to start without a sales process or an annual commitment.
- You want to test with real calls on free credit before you spend anything.
- Your call volume doesn’t justify a $30,000-a-year contract.
- You want published per-minute prices you can budget against.
Synthflow may suit you better if…
- You want a negotiated enterprise contract with launch support from day one.
- You need Synthflow-specific features or native telephony covered in its contract.
