About us

CADChain is a deep tech startup, with a focus on emerging technologies such as blockchain and machine learning, R&D, education, and intellectual property.
What we do?
We are developing IP management software for CAD data. We have one product in beta, Boris for Inventor, a second product in alpha for open-source software Blender, BlendedBoris, and a proposition for 3D printing in stealth mode.
Core team
We have a female CEO and a professionally diverse team with decades of experience.
  • Violetta Bonenkamp
    CEO & Co-Founder
    Violetta is a linguist with an MBA, 4 other Higher Education degrees, several blockchain and AI certifications, which allows her to come up with multidisciplinary and creative solutions. Violetta has been with the startup since its inception and has been supporting every aspect of its development. Now she is responsible for R&D, PR and business development.

    As a female founder, she is on a mission to inspire, and hire a diverse team that works hand-in-hand with sustainable development goals. She is the initiator of the non-profit initiative (startup game for women) called Fe/male Switch that is part of our CSR.
  • Dirk-Jan Bonenkamp
    CLO & Co-Founder
    Dirk-Jan is responsible for the legal framework that CADChain solutions need. He comes from a technical family as his father was an inventor. He bridges the gap between the law and the use of emerging technology, which is why he has immersed himself in blockchain technology and IP law with respect to manufacturing and CAD data.

    His previous experience as a politician proves to be beneficial when it comes to connecting with the public sector. His experience as an entrepreneur allows him to come up with cost-efficient solutions that fit the needs of startups and SMEs. Dirk-Jan also acts as our Data Privacy Officer.
  • Timo Wolthof
    Timo manages operations and research. 
    His strategic and operational experience in previous startups is valuable and he brings a vast knowledge of distributed ledger technologies. He became part of the blockchain sector in 2016. He is also the lead for grants and development.
  • Evgeny Malyshev
    Evgeny is CAD Developer with a background in both Mechanical Engineering and IT. He has been working for a research institution for many years. Evgeny is passionate about innovation and has an outside-the-box thinking approach. He has been instrumental in the feasibility study by helping us bring together CAD and blockchain.
Our history
A startup idea was born out of a problem that exists in the engineering industry: there’s no industry standard for CAD data protection and sharing.

Creating a globally accepted multi-layered solution that would address the lack of data protection and a reliable method of data sharing became the premise that needed to be explored.

At the end of 2018, after validating the idea at EOSIO hackathon in Hong Kong, CADChain founders were invited into a Dutch incubator.
Corporate Social Responsibility (CSR)
As part of our CSR, CADChain established Fe/male Switch, a non-profit with a focus on bringing more women into STEM. We started it during the pandemic and bootstrapped it until it received initial funding.
