We're giving Seed to Series C startups complementary API credits and early access to build with Runway Characters.
Today we are introducing Runway Builders, a program for early-stage startups building the next generation of products with generative video and real-time conversational AI.
Runway Builders gives Seed to Series C startups complimentary API credits to start building immediately, in close partnership with our team.
Runway Builders is already live with a founding cohort of startups — including Cartesia, MSCHF, Oasys Health, Spara, Subject and Supersonik — building across customer experience, synthetic media and interactive AI. We're now opening the program more broadly.
We're launching Runway Builders alongside the release of Runway Characters, Runway's real-time video agent API powered by GWM-1, our General World Model. Characters can have any appearance and any visual style, with full control over voice, personality, knowledge and actions – you can generate expressive digital personas from a single image, with zero fine-tuning required.
Use cases Runway Builders and enterprises are already exploring: AI customer support agents, interactive brand characters, personalized onboarding experiences, real-time sales assistants and synthetic media tools.
Runway Builders receive:
- Up to 500k complimentary API credits
- Runway's highest rate limits for faster development
- Access to Runway Characters via the Runway API
- Private Runway Builders community: Slack access, training sessions and direct support
