The White-Label Infrastructurefor Vertical Voice AI

Deploy hyper-specialized voice agents for Healthcare, Real Estate, and Finance under your brand. We provide the latency-optimized, compliant infrastructure; you own the client relationship.

The Wrapper Trap vs. True Architecture

Most platforms are just UI skins on OpenAI. VoiceStacks is a complete telephony infrastructure.

The Old Way

Generic Wrappers

Built for chatbots, forced into phone calls.

Unpredictable Latency

2-3s pauses while waiting for GPT-4 to 'think'.

Compliance Risk

Zero PII redaction or HIPAA-grade recording storage.

Vendor Lock-in

Your data trains their model. You own nothing.

The Platform Advantage

We built the engine.
You drive the car.

Ownership

Your URL. Your SMTP. Your Logo. We operate entirely in the background as your silent infrastructure partner.

Frequently Asked Questions

Who is VoiceStacks for?

We are built for Agencies, SaaS Platforms, and Enterprises who want to offer voice AI capabilities to their customers without building the infrastructure from scratch.

Will my customers know I'm using VoiceStacks?

No. The platform is designed to be invisible. Your clients will interact with a platform that looks, feels, and acts like your proprietary technology.

How is this different from building it myself with OpenAI?

Building a raw wrapper around OpenAI creates latency and telephony issues. We handle the "hard stuff"—interruption handling, silence detection, carrier integration, and websocket management—so you can focus on the business logic.

When does the waitlist open?

We are rolling out access in batches to ensure platform stability and high-touch support for our founding partners.
