Riza builds an "AI-first" infrastructure that enables developers and LLM-powered agents to run code safely and efficiently using a sandboxed WebAssembly (WASM) runtime. The platform supports multiple languages (including Python and JavaScript) and isolates untrusted or dynamically generated code to protect the host environment. Riza emerged from a prototype created by founders Andrew Benton and Kyle Gray (formerly of Twilio, Stripe, and Retool) and has positioned its product for development, CI, and production use. The company has announced general availability and says customers generated over 850 million code-execution requests in March. Riza plans to use its new funding to expand its team, continue work on untrusted code execution, and build more tools to make AI code generation more reliable. The product is marketed around a "Just-in-Time Programming" pattern enabling LLMs to write and execute code in production while reducing manual review and infrastructure overhead.
