Pros	Highly capable autonomous agents with real tool use and multi-turn reasoning Outcome-based pricing aligns cost with value delivered Production-grade voice agent with low-latency, natural turn-taking Strong guardrails, safety layers, and human escalation Deep enterprise integrations and dedicated implementation support	Strong at converting live website traffic into pipeline by engaging high-intent visitors in real time and routing them straight to booked meetings or the right sales rep. Automated qualification and routing reduce manual triage, letting SDRs focus attention on conversations that are most likely to advance. Deep integration with major CRM and marketing systems like Salesforce, HubSpot, and Adobe Marketo keeps engagement data connected to the rest of the revenue stack. Buyer intent and conversation insights help teams identify in-market accounts and prioritize outreach. Now embedded within Salesloft's broader revenue platform, giving teams a path to unify chat with cadences, deal management, and forecasting.
Cons	Expensive: six-figure annual contracts plus large setup fees No free trial, free plan, or self-serve option Sales-led onboarding with multi-week implementation Not a marketplace app for Zendesk/Salesforce; requires SDK integration Overkill for teams handling under ~1,000 tickets per month	Pricing is quote-based and oriented toward mid-market and enterprise budgets, making it expensive and hard to estimate for smaller teams. The platform is resource-intensive—getting real value requires dedicated staff to respond to routed conversations, not just the software itself. Its focus on sales and pipeline generation means it is less suited to general customer support use cases than dedicated helpdesk chat tools. The acquisition by Salesloft has shifted Drift toward being a module within a larger suite, which may complicate evaluation for buyers who want a standalone chat product.
