The most useful developments to watch are integration depth, operational packaging and stronger evaluation—not unsupported market-size forecasts. The reviewed evidence supports specific examples, not a quantified claim about adoption across the entire industry.
Native workflow integration is a real purchasing option. ServiceTitan’s documentation describes voice-agent actions within its service-management environment. Buyers should compare the native route with third-party options instead of assuming a separate agent platform is always necessary. (help.servicetitan.com)
Service and governance packaging deserves more attention. Vapi’s current documentation separates usage from support packages and distinguishes new-customer packaging from legacy arrangements. Compare the actual contractual package, not an old screenshot of a minute price. (docs.vapi.ai)
Evaluation is becoming more task-specific. The September 2026 τ-Elicitation research introduces a benchmark for exact capture of names, addresses, identifiers, dates and times. Its relevance to buyers is the testing question—whether critical details are captured correctly—not a transferable estimate of commercial supplier performance. (arxiv.org)
Implementation remains visible in supplier operating models. Current implementation job descriptions and a May 2026 a16z discussion with HappyRobot’s founders emphasise integration and enterprise deployment. These are supply-side signals, not proof of market demand or customer ROI. (jobs.ashbyhq.com)
The practical implication is to refresh your evidence after material configuration, software or commercial changes. A successful demonstration from an earlier release is not your current acceptance record.
