We built modern case management. Now we're defining its future.
Forty years powering how personal injury firms run their cases.
40+ Years
in case management
1,450+
personal injury firms
15,000+
attorneys and staff
Four decades inside plaintiff law.
In 1985, PINS was the first case management system for PI firms. Needles, Trialworks, and now Neos carry that work forward, shaped by the firms who use it.
Where did Assembly start?
In 1985, Burt Bank and Alan Perlin built PINS, the first case management system for personal injury law firms. PINS became Needles. A decade later, Robb Steinberg built Trialworks. In 2019, both joined as Assembly Software.
What stayed the same for 40 years?
Every product decision starts with one question: does this make life better for your firm?
Same test since PINS. Same test now.
What's different now?
The next decade of personal injury legal tech starts here. Cloud-native. Intelligence inside every case.
Every improvement, in every firm, instantly. Same focus. Sharper tools.
Outcomes that compound
Wins stack. Workflows sharpen. Practices grow stronger every year. Here's what that work looks like across the firms running on Neos across 260+ reviews.

Building Assembly's next chapter

Chief Executive Officer
Jonah Paransky has spent more than 20 years in B2B SaaS, with over a decade leading legal tech businesses.
Previously led Wolters Kluwer's enterprise legal management business as EVP and GM, ran the Business of Law Software group at LexisNexis, and most recently served as President of the Americas at The Access Group.
Believes the future of plaintiff legal tech is purpose-built integration. Off-the-shelf AI tools won't solve real legal work. AI belongs inside the case file, with full case context, not in a separate tool.
Sees the next era of legal tech as the convergence of workflow and AI inside one platform.
What backs the platform
Trust isn't a tagline. It's encryption, certifications, and a support team that answers the phone. Here's what backs the platform thousands of plaintiff firms run their practice on.
"Neos helps plaintiff firms automate workflows, securely manage documents, and save 25+ hours per case."
