To tool up its work, Precilog relies on two leading vendors: TIOBE, for continuous quality analysis (TiCS), and Verifysoft, for test coverage (Testwell CTC++). Here are the teams that design these tools.
Founded on October 1, 2000 by Paul Jansen, TIOBE Software is based in Eindhoven, the Netherlands. Its name echoes the title of an Oscar Wilde play, The Importance Of Being Earnest — a way of signaling the earnestness it claims toward clients and partners.
TIOBE specializes in assessing and tracking software quality: every day, in real time, it analyzes more than a billion lines of code for its clients around the world, with the goal of defect-free software. Most of its staff hold a master's or a PhD in computer science. This is the team behind TiCS.
CEO and founder. A computer science and philosophy graduate of the University of Amsterdam and a former researcher at Philips Research. Creator of the TIOBE Quality Indicator and the well-known TIOBE index, published every month.
CTO. Coming from automotive embedded systems — notably Bosch and DAF — as a software architect specializing in domain-specific languages and code generation, he joined TIOBE in 2018 and leads software development.
Chief Delivery Officer. A graduate of Eindhoven University of Technology, he joined TIOBE in 2022; since 2025 he has led TIOBE's deployments and support worldwide.
Based in Offenburg, Germany, Verifysoft Technology makes Testwell CTC++. Its motto sums up its direction: “For your software's quality.”
Around its Offenburg team, the company relies on a network of distributors in the United States, Italy, Israel, India, Korea, Japan, Turkey, Singapore, Australia, and China. The team covers Testwell tool development, static analysis tools, support, sales, and marketing. This is the team behind Testwell CTC++.

They only make sense in service of a need. Let's start with the diagnostic — the tool, if justified, comes next.
