    Our first tool release – Mixtures DoE tool!

    Today, we are excited to announce the release of our first subscriber tool, enabling you to carry out Mixtures DoE-type work at a tiny fraction of the cost of more established tools. We shall follow this up with a whole suite of DoE-type analysis tools over the coming weeks and months. You can get access…

  • Engineering support at your fingertips

    Engineering support at your fingertips

    When engineering teams are under pressure, the right support makes the difference Across manufacturing and engineering businesses worldwide, internal engineering teams are under sustained pressure. Projects are becoming more complex, regulatory expectations continue to increase, and experienced engineers are difficult to recruit and retain. The issue is rarely a lack of work. More often, it…
