Pertch vs Trellus

This is the sharpest head-to-head comparison Pertch has. Trellus is the only other real-time AI sales coach built for the individual seller. Both products listen to live conversations and surface coaching prompts. The differences come down to what kind of calls you’re making and how you feel about recording.

Trellus is a Y Combinator-backed product founded by former MIT researchers. It started as a Chrome extension for SDRs making cold calls, integrating directly with dialers and parallel dialing platforms. The product has expanded to include analytics, coaching, and team features.

Pertch listens to live calls through a shared browser tab, surfaces a coaching prompt every five to fifteen seconds when one’s useful, and never records audio (only a private text transcript kept for 30 days). It’s built for meetings (Zoom, Meet, Teams, Webex) more than cold calls, though it works with browser-based dialers too.

Both are good products. They serve overlapping but distinct use cases.

30-second verdict

Use Trellus if you’re an SDR making 50+ cold calls a day, you want a dialer integration, you don’t mind your calls being recorded, and you want team analytics and manager features when you scale.

Use Pertch if you’re running discovery calls, demos, or meetings rather than cold dials. You don’t want your audio recorded. You want a tool that’s yours alone, with no team or manager surface.

The honest read: if you’re an SDR cold-calling all day, Trellus’s dialer-first design is probably a better fit. If you’re an AE, founder, consultant, or SE running meetings, Pertch is.

Pricing

	Pertch	Trellus

Trellus has been less transparent about paid pricing since adding team features. The free tier with 40 dials per week is the main thing most individual users experience. Team and enterprise pricing is typically quoted.

Different products for different calls

The cleanest way to think about this: Trellus was built for cold outbound. Pertch was built for live meetings. The product decisions follow from there.

Trellus integrates with dialers like Orum, Nooks, and Outreach. It coaches you through high-volume short calls where the win condition is booking a meeting. The prompts are oriented around objections that come up in the first 30 seconds of a cold call (gatekeeper handling, opener objections, “send me an email” deflections).

Pertch is oriented around longer conversations where the win condition is qualifying, discovering, or advancing a deal. The coaching methodologies (Decisive, Qualify, Screen) reflect this. Pertch can work for cold calls if you can route the audio through a browser tab, but it’s not optimized for that motion.

If you’re not sure which describes your work, ask yourself: do you spend most of your day dialing, or most of your day in scheduled meetings? That answers the question.

The recording question

Trellus records your calls. The recordings are used for post-call analytics, transcripts, and coaching review. For SDRs and their managers, this is usually a feature, not a problem. You want to be able to review your dials, and managers want to spot patterns.

Pertch never records audio. The transcript is created live, used for in-the-moment coaching, and stored privately to your account for 30 days before deletion. No audio ever hits disk.

For a cold-calling SDR, this might be a downgrade. For an AE on a customer call, a founder talking to a prospect, or a consultant under a NDA, this is often the difference between “tool I can use today” and “tool I have to get approved by legal first.”

Two-party consent states (California, Florida, Pennsylvania, and several others) create real friction around recorded calls. Pertch sidesteps that entirely.

Where Trellus wins

You’re an SDR or BDR running a dialer all day.

You need a free option to test extensively before paying.

You want manager and team features as you scale.

You want post-call analytics, call libraries, and review workflows.

Your call style is high-volume cold outbound where the prompts need to fire in the first ten seconds.

Where Pertch wins

You run scheduled meetings (discovery, demos, follow-ups) rather than cold dials.

You can’t or won’t record calls. Compliance, privacy, two-party consent, or personal preference.

You want a tool with no team visibility and no manager dashboard, where your transcripts are visible to no one but you.

You’re not in a dialer all day. You’re in Zoom, Meet, or Teams.

You want pricing that’s predictable and published.

Can you use both?

Yes. The use cases don’t overlap much. An SDR could use Trellus for cold dialing in the morning and Pertch for discovery calls in the afternoon. We’ve designed Pertch to coexist with everything else in your stack, including Trellus.

The honest answer

Trellus is a good product for what it’s built for. If you’re a cold-calling SDR, give it a serious look. The free tier alone is generous enough to validate whether real-time coaching helps you.

If your work is meetings, not dials, Pertch is the better fit. Different product, different design choices, built for a different motion.

If you’re somewhere in between, the recording question is usually the tiebreaker. If you can record, either works. If you can’t or won’t, Pertch is the only option in the category.
