Evisort's AI contract platform is now Workday's CLM layer in 2026. Here's what changed post-acquisition, the bundled pricing, the integration story.
Key takeaways
The period from April 5 to May 5, 2026 reshaped how legal teams think about AI agent deployments. Evisort is the latest signal that the agent buying cycle has shortened from 18 months to 8 weeks at the enterprise tier — and the pricing models, integration patterns, and vendor selection criteria all moved with it.
This post pulls together what was announced, what's now live in production, what enterprise customers are paying, and what the deployment shape actually looks like inside the buyers we have visibility into. We focus on numbers and named customers wherever they are public, and flag where the data is still anecdotal.
Public confirmation from the last 30 days produces a consistent picture:
These are the public-facing numbers we can confirm. Internal benchmarks from buyers we've spoken with under NDA skew slightly higher on resolution rate and slightly lower on cost, primarily because most enterprises are routing fallback intents to cheaper models like Haiku 4.5 or GPT-4o-mini rather than running everything on the flagship reasoner.

Three questions that cut through the marketing in any vendor evaluation:
Demand the answers in writing during the procurement cycle. Vendors who refuse to commit are signaling something important about their actual production behavior.
For legal buyers, the risk-reward calculation in 2026 looks different than horizontal SaaS:
The vendors and customers winning are the ones with patience and discipline about scope expansion.
After watching dozens of bake-offs in this segment in Q1-Q2 2026, the consistent patterns:

There is no single right answer. There are several wrong ones, and the wrong ones tend to be the ones that look right on paper but fail one of the deployment-criteria checks above.
How big is the legal AI agent market in 2026? Estimates run $4-8B in 2026 software spending across the named vendors, growing 80-120% year-over-year. The estimates are wide because pricing models vary so much that comparing total spend across vendors is hard.
What's a realistic deflection or resolution rate target? 60-75% on tier-1 intents in year one is reasonable. 80%+ requires sustained tuning, deeper tool integration, and disciplined intent expansion. Targets above 90% in year one are usually unrealistic and will lead to unhappy customers when escalation paths break.
Should we buy from an incumbent or a pure-play? Incumbents (Salesforce, Zendesk, Microsoft) win on integration. Pure-plays (Sierra, Decagon, Ada) win on agent quality. The gap is narrowing through 2026 — by end of year it may not matter much for most use cases.
What's the riskiest part of a legal AI agent rollout? Knowledge base quality. The agent is only as good as the underlying content it can ground answers in. Most failed deployments traced back to outdated, contradictory, or poorly structured knowledge bases — not to model issues.
