About Trellus

Trellus is a New York–based sales technology startup that provides an AI-powered cold calling copilot and embedded dialer for sales development teams. Built and operated by Outpost Labs Inc. (dba Trellus), the platform runs as a Chrome extension on top of tools like Salesloft, Outreach, HubSpot and Apollo, turning them into high-velocity power and parallel dialers while delivering in-call coaching prompts. ycombinator.com

Founded in 2022 and backed by Y Combinator (YC W22) and other early-stage investors, Trellus focuses on real-time guidance rather than only post-call analysis. The software listens to live conversations, then surfaces behavioral cues (e.g., slow down, pause, ask a question) and objection-handling suggestions while reps are on the phone. It also automates repetitive tasks such as dialing, voicemail drops, call dispositioning, call notes and follow-up email generation so reps can spend more time in conversations. ycombinator.com

On the infrastructure side, Trellus integrates natively with browser-based dialers and popular sales engagement platforms via its Chrome extension, rather than requiring a standalone dialer UI. This lets teams keep their existing workflow and tech stack while adding capabilities like multi-line dialing, AI-generated prospect and company research, real-time transcription, conversation analytics and number health/spam monitoring. For managers, Trellus provides dashboards and call scoring to identify best practices, close performance gaps between reps and run structured call blitzes in a virtual sales floor environment. ycombinator.com

Trellus primarily serves B2B organizations with outbound motions—especially SaaS and technology companies that rely heavily on SDRs and BDRs for pipeline generation. With a free individual plan, self-serve paid tiers and a customizable business plan for teams, Trellus positions itself as a more affordable, AI-first alternative to traditional parallel dialers such as Orum and Nooks, emphasizing conversation quality and coaching over pure dial volume. ycombinator.com
