About Stability AI
Stability AI develops generative AI models for images, video, audio and 3D. The models can be self-hosted under a licence, used through a platform API or accessed through cloud partners. In April 2026 it introduced Brand Studio, a managed creative production platform for enterprise teams. It is headquartered in London.
TechCrunch and Wikipedia date the company to 2019 and name Emad Mostaque and Cyrus Hodes as co-founders. Stable Diffusion, a text-to-image model released in August 2022, had been downloaded or licensed over 200,000 times by October. Wikipedia says Mostaque stepped down in March 2024, and Stability's own announcement says interim co-chief executives ran the company from then. On 25 June 2024 the company appointed Prem Akkaraju, the former chief executive of Weta Digital, as chief executive and Sean Parker as executive chairman. James Cameron joined the board in September 2024 and Robert Legato became chief pipeline architect in March 2025.
Releases since then include Stable Diffusion 3.5 in October 2024 and Stable Audio 3.0 in May 2026, which Stability says was trained on fully licensed data. It launched Stability AI Solutions for enterprises in August 2025. Its site names HubSpot, Mercado Libre and Stride Learning in case studies.
Stability announced a collaboration with NVIDIA on a Stable Diffusion 3.5 microservice in August 2025 and brought image services to Amazon Bedrock in September 2025. It announced partnerships with Electronic Arts in October 2025, Universal Music Group later that month and Warner Music Group in November 2025. It reports SOC 2 Type II and SOC 3 compliance.
Stability raised 101 million dollars in October 2022, led by Coatue, Lightspeed Venture Partners and O'Shaughnessy Ventures. A June 2024 round, with no amount disclosed, included Greycroft, Sound Ventures, Sean Parker and Eric Schmidt. On 25 August 2026 it announced a 76 million dollar Series B, with Electronic Arts, Sony Music Group, Universal Music Group, Warner Music Group, AMD Ventures and Pacific Alliance Ventures among new investors. The company puts total funding at 232 million dollars and says the money will go to creative production products, applied research and professional services.
