In 2023, Flaviu Radulescu founded Runware after discovering that existing text-to-image AI solutions, while advanced, were too slow for practical use. Partnering with Ioana Hreninciuc, he launched Runware as a developer platform focused on delivering instant image, video, and audio generation.
Since its inception, Runware has experienced rapid expansion, enabling over 200,000 developers to create more than 10 billion pieces of media, according to statements shared with TechCrunch.
Runware’s platform allows developers to seamlessly integrate its API into their applications, streamlining the process of generating various media assets without the need for separate integrations or additional infrastructure. The company’s proprietary AI inference system supports open-source models, offering immediate access to new releases and maintaining competitive pricing, as explained by Hreninciuc, who leads operations and go-to-market strategy.
On Thursday, Runware revealed it had secured $50 million in Series A funding, led by Dawn Capital. Shamillah Bankiya from Dawn Capital will join the company’s board. Other investors in this round include Comcast Ventures, Speedinvest, Insight Partners, and a16z Speedrun, bringing Runware’s total funding to $66 million.
Hreninciuc emphasized that Runware stands out due to its cost-effective pricing and a fully integrated API. The company’s Sonic Inference Engine, which operates on custom AI hardware, is a key differentiator. Runware also collaborates with external AI cloud providers, allowing it to dynamically allocate workloads and scale memory as needed.
“We’ve heavily optimized the loading and offloading of models on the software side, enabling us to support over 400,000 models and provide real-time inference for any of them,” Hreninciuc noted.
Developer tools for image and video generation have recently attracted significant venture capital. For example, Fal.ai recently raised $140 million at a $4.5 billion valuation, focusing on offering a wide range of models rather than speed. Hreninciuc identifies Fal.ai and Replicate—another startup enabling open-source model deployment with minimal code—as key competitors.
Unlike competitors that charge based on GPU compute time, Runware adopts a pricing model similar to Stable Diffusion and Flux, charging per generated image. This approach allows customers to pay only for what they use, rather than purchasing fixed compute blocks.
The new funding will support further expansion of Runware’s infrastructure, with ambitions to power over 2 million models using the Sonic Inference Engine. The company’s overarching goal is to become the universal API for generative AI, enabling any model to run on its platform.
“We’re also moving quickly into new types of media,” Hreninciuc added, noting plans to grow the team—currently around 25 people—to support this expansion.
Ultimately, Hreninciuc envisions Runware enabling applications to scale to millions of users while maintaining healthy profit margins, making advanced AI more accessible and affordable. “This benefits everyone—from app creators to end users—by putting powerful AI tools into more hands around the world,” she said.
