Self-improving
Opening experiments run for you.
Breakout sells an inbound AI SDR: it identifies who's on your site, nudges them with personalized content and books the meeting. Darwin books meetings from your website too, and spends its time testing which openings get people talking. Here's how the two compare.
Opening experiments run for you.
Your website becomes your starting point.
Try Darwin with included bookings.
Breakout wants to be your whole inbound motion: it figures out who's visiting, runs the campaigns, chats, and hands the good ones to reps, and the AI SDR tier starts at $2,000 a month. Darwin is a narrower bet. It's a chat window that books meetings and keeps rewriting its own openings, and there's no monthly fee until it's earned one. The rows below walk through where that difference shows up.

An inbound AI SDR for B2B revenue teams running full demand gen.
Breakout lists its prices, which is rarer than it should be in this category. Signals runs from $500 a month and covers visitor identification; Growth, the tier with the actual AI SDR, runs from $2,000 a month; Enterprise is a conversation with sales. There's a free 30-day trial. Darwin's Origin plan costs nothing per month. You get five bookings included and pay for each meeting booked after that.
69Yes. Breakout says it books meetings both in chat and from its Smart Forms, with pre-filled one-click calendar booking, though its pages don't name the calendar providers. Darwin offers a time in the conversation and completes the booking in whichever scheduler you've connected. With both, check what gets recorded as a finished booking.
238Published by Darwin, using the official documentation linked below. This is a comparison of documented capabilities, not a hands-on benchmark. “Not documented” means the reviewed sources do not establish that capability; it does not prove absence. Breakout publishes monthly tiers; several capability rows read “Not documented” because its public pages are marketing pages rather than product documentation. Darwin bills for booked meetings. Setup means preparing a draft, not automatically installing it.
Personalized nudges by industry, size and region; video nudges; competitor comparisons; pre-filled one-click calendar booking; routing to reps.
