We are Reactive

About Quantum Leaps

Quantum Leaps, LLC makes modern, real-time embedded (RTE) software especially suitable for mission-critical systems. Our lighweight QP™ real-time frameworks and the QM™ modeling and code-generating tool have been chosen by hundreds of companies around the world to build electronic products ranging from implantable medical devices to complex weapon systems.


Our mission is to bring quantum leaps of innovation to embedded systems programming by facilitating widespread adoption of reactive programming, hierarchical finite state machines (UML statecharts), unit testing, graphical modeling and automatic code generation.


Customers & Markets

Our software and tools are used in millions of products worldwide by companies large and small, in IoT, consumer, medical, industrial, wireless, networking, robotics, research, automotive, defense, and many other industries.


Quantum Leaps, LLC was founded by Dr. Miro Samek in 2005 in Palo Alto, California—at the heart of Silicon Valley—and subsequently relocated to Chapel Hill, North Carolina in 2007. The company has always been independent, debt-free, and profitable from day one. We're here for the long haul.

Professional Open Source Company

Quantum Leaps, LLC is a second-generation professional open source company that has established a sustainable business based on dual-licensing.

In contrast to most of the first-generation open source companies, we own all the intellectual property in our software. Therefore we can offer traditional commercial licensing to all customers interested in retaining the proprietary character of their software.

This increasingly popular, strictly quality-controlled, single-vendor commercial open source business model combines the best of the open source and proprietary software worlds to make open source a safe choice for the embedded systems vendors. This includes the accountability for the licensed intellectual property, professional documentation and technical support expected of a traditional software vendor as well as transparent development, availability of source code and active community inherent in open source projects.

How We Operate

We've built the company that we'd ourselves want to do business with. Here are the main principles that guide us:

The UML and other modern approaches to software development offer true benefits, but there is also too much fluff and detachment from reality. We cut through this noise and provide only practical, efficient, working software that has been battle-tested and proven in real-life systems.

Any piece of our software that goes into an embedded device is openly available in source code, because you need to be able to understand, adapt, recompile, and debug the software in source code.

We own all the intellectual property in our software. Therefore, we can offer closed-source licensing and the accountability for the licensed intellectual property to all commercial customers interested in retaining the proprietary character of their software.

With every commercial license we offer professional technical support. This is designed to motivate us to keep our software free of bugs, easy to use, and clearly documented with many examples to minimize our support load and expenses.

This is in contrast to many first-generation open-source vendors, where such strategy would actually lower their revenue and profit from support contracts.

All our software and documentation is truly free to download from public open source repositories (currently SourceForge and GitHub), without registration or teasing private information out of our potential customers. We trust you, because the sustainability and thriving of our business is ultimately in your own best interest as well.

Our customers fund our daily operations by purchasing commercial licenses for our software. We answer to them — not investors, the stock market, or a board of directors.

We believe everyone is entitled to the best price we can offer. Our prices are open and transparent, published right on our site.

Our software and tools make software development fun again. You work at a higher level of abstraction of active objects and state machines, instead of struggling with "spaghetti" code and chasing race conditions in projects based on the traditional "shared-state concurrency with an RTOS" approach.


Miro Samek

Dr. Miro Samek

Founder and CEO

Dr. Miro M. Samek is the creator of the open source QP™ real-time frameworks as well as the free QM™ modeling tool. His practical books about UML state machines, active objects (actors), and event-driven frameworks for embedded systems are among the most popular on the market. Miro has also published dozens of technical articles for Embedded Systems Programming/Design, Dr. Dobb's Journal, and a column for C/C++ Users Journal. His extensive industry experience ranges from safety-critical software development at GE Medical Systems through real-time embedded software design at two Silicon Valley companies specializing in GPS technologies. Software he wrote continues to power billions (yes, thousands of millions) of products. Dr. Samek earned his Ph.D. in nuclear physics at GSI (Darmstadt, Germany).
