Synthflow
No-code AI voice agent platform for phone automation across customer service, reception, and appointment workflows.
SMBs and mid-market ops teams automating inbound phone workflows such as reception, scheduling, and basic support.
Enterprises that need a fully custom voice stack with in-house telephony engineering, or buyers wanting only a raw voice API.
Verdict
Synthflow is an AI voice agent company founded in 2023 by Hakob Astabatsyan with Albert Astabatsyan and Sassun Mirzakhan-Saky. It sells a no-code platform for building and deploying phone agents for customer service, reception, appointment setting, and related voice workflows, with enterprise packaging on the pricing page. It matters because phone still carries a large share of customer contact, and Synthflow packages voice agents for operators who will not staff a voice ML team.
