About

What is Trellus

Trellus sits inside your existing dialer and fires real-time coaching cues, objection handling prompts, and prospect research to reps while a call is still live. It transcribes and scores every call automatically, then pushes notes and updates directly to HubSpot, Salesforce, or whichever CRM the team runs. The standout capability is its AI voice bot for rep practice — reps can simulate prospect conversations before hitting the phones, which is rare in this category. It's built for SDR, BDR, and AE teams at mid-market and enterprise companies that run high-volume outbound and need coaching at scale without adding headcount. The honest limitation: Trellus is a UI-driven tool with no public API, so it can't be wired into automated workflows or agent pipelines without manual intervention.

Our verdict

Vanderbuild take

Trellus is a focused sales coaching and assistant tool — it does one thing well: keeping reps sharper on live calls, and it's a credible fit for SDR/BDR teams and AEs at scale-up and enterprise orgs that want coaching embedded in the dialer rather than bolted on after the fact. On the agentic readiness front, there's no API and no MCP server — this is UI-only, meaning you cannot drive it from an agent or plug it into an orchestration layer without scraping, which is a real ceiling if your stack is moving toward agentic outbound. Pricing lands at the enterprise tier with a custom Business plan on top of per-seat fees reaching $149.99/month, so expect procurement involvement and a proper business case before rollout. The free tier is useful for individual reps to trial the core coaching loop, but team-level analytics and custom coaching models are gated behind the higher tiers, which is where the actual value for RevOps lives.
