Ensuring safety-critical software is built on a solid foundation
Founded in 2014 in Amsterdam, The Netherlands
Since Amsterdam’s earliest days, its buildings have stood on deep foundation piles – driven through clay and peat to reach solid sand. At Solid Sands, we take the same approach to software reliability.
Founded in 2014 by Marianne Damstra and Marcel Beemster, we set out to ensure that safety-critical software is built on a solid foundation – just like the city itself.
Today, our world isn’t built on bricks – it’s built on code.
Software drives autonomous vehicles, secures railway networks, powers medical robotics, controls aviation, and enables space exploration. Yet software is only as strong as the trust behind it. A single flaw can mean failure – and in safety-critical industries, failure is not an option.
Driven by relentless precision, deep expertise, and an unwavering commitment to quality, we ensure our clients’ safety-critical software is built on a solid foundation.
That’s why we created SuperTest™ and SuperGuard™, the world’s most rigorous compiler validation and library test suites. By eliminating uncertainty and ensuring quality, we give our clients more than just testing tools — we give them Confidence by Design.
“Since early times, houses in Amsterdam have been built on wooden foundation piles that are driven deep into the clay, peat, and water until they reach the first layer of solid sand.”

Johannes Vermeer is known for his photorealistic attention to detail using pigments such as lapis lazuli to create a world more perfect than the real one. It is still a mystery how he was able to achieve the masterly treatment of light and color in his work, since the appreciation of his paintings came only two centuries after his death. SuperTest aims to attain the same perfection as Vermeer, but without the mystery.

Solid Sands starts in November 2014 and has its headquarters in Amsterdam, the Netherlands. Our mission is to put quality into C. We do that by improving the quality of C and C++ compilers, libraries and analysis tools, and their safe and secure use, with the best possible test and validation suite.
1984
When SuperTest started, there was only K&R C. As ISO standardization progressed, SuperTest was extended to track the latest developments. We plugged holes in the suite by adding tests for errors not initially found. We created generators to add systematic testing for complex parameter spaces. SuperTest is now the most complete validation suite for C and C++ available.
