Deltek

What It Does

Deltek makes enterprise software for project-based businesses, covering ERP, project portfolio management, CRM, and professional-services automation. Its products are aimed primarily at government contractors, architecture and engineering firms, consultancies, and other services organisations that bill against projects. It is not a legal-specific vendor; any relevance to law firms comes from generic project accounting and time/billing rather than legal-domain features.

What We Found

Deltek was founded in 1983 in Herndon, Virginia by Donald and Kenneth deLaski. It was acquired by Roper Technologies in 2016 for a reported $2.8B and operates as part of Roper’s software portfolio. Headcount is in the low thousands as of mid-2026. Its presence in a legal-tech directory most likely reflects time-and-billing or project-accounting overlap rather than a dedicated legal product.

What We Haven’t Verified

• Whether any Deltek product is marketed to or used by law firms specifically.
• The published integrations (Microsoft Outlook, Procore, Prophix, Raken) — we haven’t tested them, and they point at construction/finance use cases, not legal.
