Billing infrastructure for the AI era

Artificial intelligence broke the economics of software. Grant is built to fix it.

Every AI company goes through the same journey. Leverage frontier models to find product-market fit. Mix frontier and open sources models to get the costs under control. Fine-tune on your proprietary data to get the extra performance at fraction of a cost.

Each stage is additional complexity and more infrastructure to manage. But the billing systems of the last decade were designed for subscriptions, not for agentic products, where costs are unpredictable and change overnight every time a new model ships.

That's the problem Grant exists to solve. We make it easy to monetize your AI product, meter every inference stream, update customer balances, and show cost and margins in real time.

We believe the next decade should produce many enduring AI companies, not just a few. To make that happen, we built the financial infrastructure that supports you from your first customer to your first foundational model.
