Revel, a unified software platform for hardware test and control, announced it has raised $150 million in Series B funding to accelerate its expansion across aerospace, defense, robotics, and industrial markets. The round was led by Index Ventures, with significant participation from Redpoint Ventures and returning investors Thrive Capital, Felicis, and Abstract Ventures. Prominent angel investors, including Dylan Field, co-founder and CEO of Figma, also participated. Nina Achadjian, partner at Index Ventures, led the round and joined Revel’s board.
Revel is focused on modernizing the software layer used to test, validate, and command increasingly autonomous and software-driven hardware systems. From rockets and propulsion systems to advanced robotics and nuclear energy infrastructure, many of today’s complex physical systems rely on legacy software tools built decades ago, before modern collaboration workflows, deterministic execution, and real-time observability became standard in software engineering.
The company’s platform enables engineering teams to visually configure hardware systems, monitor live telemetry, and safely issue commands in real time. Its proprietary programming language, RevelCode, features Python-inspired syntax combined with deterministic execution, precision, and debuggability designed for high-consequence environments. The platform is intended to accelerate testing cycles, reduce costly errors, and support mission-critical infrastructure.
Revel has secured customers, including Impulse Space, Radiant Nuclear, and Astro Mechanica, across the aerospace, defense, and advanced energy sectors. As demand for safe, software-defined hardware systems grows, the company is expanding into a broader range of industrial control applications.
The new capital will be used to expand the team, continue product development, and support broader market deployment.
Founded by engineers from SpaceX, Anduril, and Palantir, Revel is building software infrastructure designed to support the next generation of complex hardware systems.
KEY QUOTES
“I spent a decade building and operating systems where reliability wasn’t optional. Testing and control sit at the center of how complex hardware is developed and deployed, but the tools supporting that work haven’t kept pace with system complexity. We built Revel to give engineers infrastructure they can trust from prototype through production.”
Scott Morton, Founder And CEO, Revel
“We believe hardware is entering a new era — more autonomous, software-driven, and operationally complex than ever before. Yet the underlying software infrastructure hasn’t kept pace. Scott brings rare, firsthand experience operating at the highest levels of reliability and scale. By modernizing this foundational layer, Revel has the potential to define a new category in how complex hardware is built and run.”
