A case management powerhouse


By unifying Needles and Trialworks under a common roof, Assembly Legal has combined two of the most trusted brands in case management software. This has created the scale necessary to attract a world-class team and invest heavily in product innovation, culminating in the introduction of our new cloud product, Needles Neos.

With our unique combination of decades of experience and deep industry knowledge with a revitalized team, cutting-edge technology, and a reputation for best-in-class customer support, Assembly Legal proudly stands apart from all other case management companies.
