An AI SDR, or Sales Development Representative, is a voice-based AI agent that takes on the early stages of your sales process. It can initiate conversations, qualify prospects, follow up on interest, and even schedule meetings. It works just like a human SDR; only it never sleeps, scales effortlessly, and can handle dozens of conversations at once.
By automating repetitive outreach and qualification tasks, Synthflow helps your sales team focus on closing deals instead of chasing leads. The AI SDR can make thousands of calls per day, follow a tailored pitch, ask the right qualifying questions, and pass high-intent leads directly to your reps. This means faster follow-ups, better conversion rates, and a more efficient pipeline.
It’s built for a wide range of scenarios. You can use it for cold outreach, warm lead follow-ups, event reminders, reactivation campaigns, or even demo scheduling. Whether you prefer a fixed script or a more adaptive flow, the AI handles it smoothly and naturally.
Yes, it integrates seamlessly with CRMs like Salesforce, HubSpot, and Pipedrive, among others. This means your team gets real-time updates, call summaries, recordings, and lead data automatically, without having to juggle between tools.
Very natural. Synthflow uses advanced voice synthesis technology to create voices that are expressive and human-like. The AI speaks clearly, adjusts tone and pace, and even knows when to pause. It doesn’t sound robotic, and most people on the other end of the call won’t know they’re not speaking to a person—unless you want them to.
That’s completely up to you. You can configure the AI to introduce itself as a virtual assistant or let it speak as a human rep. In either case, what really matters is how relevant and respectful the conversation is—and when that’s done right, prospects stay engaged.
If the AI encounters something unexpected, it can either transfer the call, schedule a callback, or send a detailed summary to your team for follow-up. Nothing slips through the cracks, and your human reps always have full context when they take over.
Synthflow is designed to be incredibly easy to use, highly scalable, and deeply customizable. You don’t need to be technical to set it up, and it integrates with the tools your team already uses. Compared to other providers, Synthflow offers lower latency, more lifelike voices, better support, and a pricing model that’s clear and fair. It’s built for teams that want real results without a complicated setup.
