Assembly Software

What It Does

Assembly Software is the parent company behind two long-running legal case management brands, Needles and TrialWorks, aimed primarily at plaintiff and personal-injury law firms. Its main product, Needles Neos, is a web-based case management system covering client intake, matter and document management, workflow automation, and calendaring. The portfolio targets small-to-mid-size litigation practices.

What We Found

Assembly Software was formed in 2017 (announced publicly in early 2019) by combining Needles and TrialWorks, two case management vendors with a long combined operating history. The company released Needles Neos, its cloud platform, in March 2020. Vendor and press material describe a base of thousands of law-firm clients across the two brands. Lawyerist carries a published review of Needles Neos.

Who It’s For

Plaintiff / personal-injury firms

• Workflow fit: Client intake → matter management → document automation → calendaring
• The Needles and TrialWorks heritage is specifically plaintiff-side litigation, so the templates and workflows lean that way.

In-house legal / corporate

• Workflow fit: Not the target. Skip — this is built for plaintiff law-firm case management.
