Honest comparison · updated September 2026
Amplemarket calls itself an AI sales copilot, and of everything in this comparison series, it comes closest to Rocketship's ambition: a contact database, intent signals, multichannel sequencing, a dialer, even AI-generated voice messages. But it names its own limit plainly — Duo drafts the outreach and the reply, and, in Amplemarket's words, "you just have to approve it, and that's it." Every send waits on a person's click. Duo needs a click before anything ships. Sophie doesn't: she picks the lead, writes to them, and by the time a reply lands she has already answered it and put a meeting on your calendar — before anyone on your team would have opened the inbox to look. Flat, from $24.99 a month, no per-seat floor, no approval queue.

The cost math
Amplemarket bundles more into one per-seat price than most of this batch — data, signals, sequencing, a dialer, voice messages — and that's worth crediting. But price the entry point: the Startup plan is $600 a month on an annual term for two users, which works out to roughly $300 a user a month before you've sent a thing. Growth and Elite step up from there, four and ten users included, and both are priced by quote rather than published — so the floor is the only number you can check without a sales call.
And at that price, the send still isn't unsupervised. Amplemarket's own product description of Duo is direct about it: the AI drafts the message or the reply, and "you just have to approve it, and that's it." That's a genuinely fast review step — faster than reading a whole email cold — but it is still a person, still a click, still a human required for every message that goes out and every reply that comes back. It is the same structural gap as a unibox: better assisted, not unsupervised.
Rocketship charges $24.99 a month flat, no per-seat floor, and nobody clicks approve before anything goes out: the buyer gets decided on, the message goes out under your name, and whatever comes back gets opened and answered without a review step — then the meeting lands on the calendar and the phone gets a live, two-way conversation, not a recorded drop, any hour, on your own number. The site it can build, with Stripe Connect on your domain, rides along in the same subscription. Amplemarket's $300-a-seat floor buys a faster copilot. $24.99 buys an agent that doesn't wait on you at all.
Track the approvals, not just the replies
Amplemarket sells with a card at the Startup tier, so run the test directly: start both this week and track two numbers for thirty days — what got approved and sent by a person on your team, and what got answered and booked without anyone touching it. Amplemarket's Duo feed will show you drafts waiting on a click. Rocketship's calendar will show you meetings nobody approved by hand. Keep whichever produced a customer with less of your time in the loop.
