Revel, a software platform built for hardware test and control, has raised $150 million in a Series B round at a valuation exceeding $1 billion. Index Ventures led the investment, with significant participation from Redpoint Ventures. Returning investors Thrive Capital, Felicis, and Abstract Ventures also joined the round, alongside notable angel investors including Dylan Field, co-founder and CEO of Figma.
The funding reflects growing conviction that the software supporting complex physical systems — from rockets to nuclear reactors — is overdue for a serious rebuild.
Modern hardware systems are more autonomous and software-driven than at any point in history. Aerospace vehicles, advanced robotics, and energy infrastructure now operate at levels of complexity that demand precise, real-time software control. Yet many of the tools engineers use to test and command these systems were built decades ago, well before concepts like real-time observability, modern collaboration workflows, and deterministic execution became standard practice in software engineering.
That gap is what Revel was founded to close. The company provides a unified platform that lets engineering teams visually configure hardware systems, monitor live telemetry, and issue commands in real time. Its proprietary programming language, RevelCode, combines Python-inspired syntax with the kind of precision and debuggability required in high-consequence environments.
"I spent a decade building and operating systems where reliability wasn't optional," said Scott Morton, founder and CEO of Revel. "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."
The Series B proceeds will fund team expansion, continued product development, and broader deployment across industrial markets. Revel is accelerating its push into a wider range of industrial control applications, with particular focus on the infrastructure that powers the next generation of mission-critical systems.
Beyond headcount and product work, the company plans to deepen its presence across aerospace, defense, robotics, and advanced energy — markets where the cost of software failure is not just financial. Revel's platform is already in use at organizations like Impulse Space, Radiant Nuclear, and Astro Mechanica, signaling early traction among some of the more ambitious hardware companies operating today.
Revel was founded by engineers who came out of SpaceX, Anduril, and Palantir — organizations where software reliability under pressure is not a nice-to-have. That background is baked into how the platform was designed: built for environments where errors carry real consequences and testing infrastructure has to perform consistently under load.
The platform addresses what has historically been a fragmented and underfunded part of the hardware development stack. Testing and control software is not glamorous work, but it is where safety, speed, and reliability are ultimately proven. By bringing modern engineering principles to this layer, Revel is positioning itself at the foundation of how complex hardware gets built and operated.
Index Ventures Partner Nina Achadjian led the round and joined Revel's board. Her perspective on the investment reflects a broader thesis about where hardware development is headed.
"We believe hardware is entering a new era — more autonomous, software-driven, and operationally complex than ever before," said Achadjian. "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."
Revel's other backers include Redpoint Ventures, Thrive Capital, Felicis, and Abstract Ventures, alongside angel investors with deep roots in software and product development. The round builds on prior funding from this same investor base, underscoring continued confidence in Revel's direction.
