Synthflow is an enterprise voice AI platform that automates phone calls using AI-powered voice agents. It handles both inbound and outbound calls — answering questions, routing based on context, booking appointments, detecting voicemails, and sending SMS follow-ups. The platform uses advanced speech recognition and natural language understanding to enable real-time conversations at scale, and it integrates with CRMs and ERPs so call data flows directly into your existing business systems without manual entry.
Yes, Synthflow lets you build and configure your AI agent for free using their library of industry templates or by creating your own from scratch. You can design custom call flows, set up voicemail detection, and configure integrations without any upfront cost. When you're ready to actually make or receive calls, the platform transitions to a pay-as-you-go (PAYG) model where you only pay for the actual calls and chats conducted, so there's no financial commitment during the design and testing phase.
Synthflow uses end-to-end encryption and holds HIPAA, SOC 2, GDPR, and PCI DSS compliance certifications. This makes it suitable for industries with strict data handling requirements, including healthcare, finance, and enterprise services. You can also define guardrails, escalation rules, and fallback responses to keep conversations on-brand and prevent the AI from sharing unapproved information during sensitive calls.
Yes, Synthflow offers native integrations with popular CRMs including HubSpot, GoHighLevel, and Salesforce, allowing automatic syncing of call data, contact updates, and follow-up triggers. Beyond CRM, it connects to ERPs and platforms like Google Cloud and Zapier, giving you access to hundreds of additional apps. These integrations work without custom development, so call outcomes can automatically update records, create tasks, or trigger workflows in your existing systems.
Synthflow agents are designed to manage uncertainty gracefully. When the AI encounters a question it can't answer or detects caller frustration, it can ask clarifying questions, offer alternative responses, or escalate to a live human agent. You have full control over handoff triggers — you can configure escalation based on the number of failed response attempts, caller sentiment, or specific keywords. This ensures callers always have a path to resolution rather than getting stuck in an unhelpful loop.
