Trellus

Trellus is a Y Combinator-backed AI sales copilot that embeds directly into your existing sales engagement platform as a Chrome extension. Rather than replacing your tech stack, it layers parallel dialing, real-time AI coaching, and call analytics on top of tools like Salesloft, Outreach, HubSpot, and Apollo.

Core Features:

Embedded parallel dialer (up to 5 lines) that works inside your existing SEP, eliminating context switching between platforms

Real-time AI coaching that provides live suggestions, objection handling prompts, and competitor insights during calls

AI voice agents that simulate prospects for roleplay practice, created from your team's past calls in seconds

Automated caller ID health checks and number rotation to stay out of spam lists and boost connection rates

Superhuman for LinkedIn feature consolidating all LinkedIn and Sales Nav messages into one inbox with snoozing, categorising, and keyboard shortcuts

Best For:

Individual SDRs and small-to-mid sales teams (1-15 reps) who want to boost calling productivity without ripping out their existing tech stack. The Chrome extension approach means zero migration. Particularly strong for teams already on Salesloft, Outreach, or Apollo who want parallel dialing and AI coaching without paying for a standalone dialer like Orum or Nooks. Note: Trellus is an add-on, not a standalone phone system. You still need an underlying platform.
