Gradium

At Gradium, we're building real-time voice models (STT, TTS) with industry-leading voice cloning, semantic turn-taking, and accuracy that handles the hard cases. Every day we see new applications emerge: voice AI for gaming, customer care, media, and markets we haven't imagined yet. The builders driving this wave shouldn't be held back by cost or infrastructure. That's why we're launching the Gradium Startup Program to back them from day one.

Bridging the Scaling Gap

We have heard from many of you that the current landscape of voice API pricing makes it difficult to scale. When voice is a core component of your product, not just a feature, high per-minute costs can kill your unit economics before you even get off the ground. We know how hard it is to balance high-quality infrastructure with the realities of being early-stage. That is why we are launching the Gradium Startup Program: to ensure that the cost of great voice technology isn't a barrier to your growth.

Craft a Unique Identity with Voice Cloning

In a world of generic AI assistants, your brand’s personality is your greatest asset. A differentiating part of our platform is high-fidelity voice cloning, allowing you to move beyond "off-the-shelf" voices. Whether you are creating a specific character for a game or a signature brand voice for your interface, our technology allows you to craft a unique, recognizable identity for your startup in seconds. This ensures your product does not just function well: it sounds like you.
