Software Improvement Group expands Mendix quality and security proposition by acquiring Mendix-related technology from Siemens partner CLEVR

30 May 2024

With the acquisition of CLEVR’s IP, Software Improvement Group expands its global customer base and intensifies its partnership with Mendix and Siemens.

Amsterdam, The Netherlands – 30 May 2024

Software Improvement Group (SIG), a leader in traditional and AI software quality assurance, has acquired the IP and customer contracts from all CLEVR’s Mendix-related quality assurance technology.

Mendix, a subsidiary of Siemens, is the global leader in enterprise low-code.

SIG’s 2023 benchmark report showed that low-code systems are more entangled, especially at larger system sizes. This makes them harder to maintain, compared to systems built in modern general-purpose languages. The report also highlighted that having higher-quality architecture enables you to address issues twice as quickly as lower-quality architecture.

As the industry embraces these powerful low-code tools, we must also enhance our processes to ensure that our rapid creations do not become liabilities. Low-code is still code, after all. Successfully deploying complex applications at scale requires a balanced approach.” – Luc Brandts, CEO of Software Improvement Group

CLEVR has operated specific quality technology for Mendix, which are now acquired by SIG:

In the past, SIG designed and launched:

QSM is a platform powered by Sigrid, SIG’s leading software excellence platform. QSM is specifically designed for Mendix applications and includes a Mendix-approved ruleset for detecting common Mendix security misconfigurations and best practice violation rules.

With the acquisition of CLEVR’s IP, SIG acquires the rights to all its Mendix-related technology and gains new customers from around the world. By doing so, SIG firmly positions itself as the authority within the Mendix community to help improve and scale the deployment of Mendix applications, next to delivering similar propositions to other low code platforms and high code solutions.

Organizationally, this acquisition will have no impact on current customers, as support and maintenance will continue to be provided.

SIG ensures full support for all current versions of ATS, APD, and ACR until the end of 2026.

With this acquisition, we are proud to welcome new customers from all over the world and are extremely excited to help them build high-quality software applications and enhance their capabilities to review its scalability, quality, security, and dependency on third party applications. Acquiring CLEVR’s IP will not only improve our offering but will also further strengthen our relationship with CLEVR, Mendix, and Siemens.” – Luc Brandts, CEO of Software Improvement Group

SIG taking over our software technology portfolio is fully in line with our strategy and allows us to keep focus on what we do best: The reselling, delivery and support of (PLM, MOM, low-code) software solutions. It’s for this exact reason that we have further engaged with SIG into a partnership in which we – as the trusted advisor for our clients – use SIG software for health and quality assurance“. – Jeroen Hanekamp, CEO of CLEVR
