At larger firms, deals tend to stall after the demo, in approval and rollout (typical). Clio's 2025 Legal Trends Report says adoption cycles at larger firms can be slower because of more involved purchasing and approval processes, which stretch the time it takes to get a new tool approved. Clio sells legal software, and its vendor survey of 1,702 US legal professionals (1,202 of them Clio customers) leans to small and midsize firms, so treat the large-firm line as Clio's observation.
Expect AI tools to roll out in stages. ILTA's 2026 survey found more than half of respondents issuing licenses for the AI assistant built into their office software only on request. CLOC, the legal operations association, summing up its European summit in March 2026, wrote that successful AI programs "require governance, structured pilots, training, and measurement of business impact." Expect a pilot with a named group, a named owner and a training requirement, not a firm-wide rollout.
The objections that hold a pilot back are known. In the ABA's 2024 AI TechReport (a single survey: 512 respondents on this volume, fielded October to December 2024), the top concerns about AI tools were accuracy (74.7%), reliability (56.3%), data privacy and security (47.2%), cost of implementation (22.1%) and time to learn (21.3%). Build the pilot plan around those five.
No neutral source we found measures how long legal tech pilots or sales cycles run, so do not plan around a number someone quotes you. Plan around the steps: security review, AI policy check, pilot scope, a success measure agreed up front, and the approvers' meeting.
