Prosp

Prosp is an AI-powered LinkedIn outreach tool built specifically for the agency and high-volume sales use case, where you're managing prospecting across many accounts at once and personalization at scale is the whole game. You find leads with its built-in finder and Chrome extension, then launch campaigns where the AI writes personalized icebreakers and messages drawn from each prospect's profile and recent activity. It goes a step further than text by automating voice notes inside sequences, and it can even clone your voice so those notes sound like you, which is genuinely uncommon in this space and the feature most users single out. The tool was founded in 2023 by Yann Dine, based in Paris, who built it to help agencies and sales teams scale LinkedIn outreach and lean on AI for hyper-personalization to lift positive reply rates. It's sold both directly and through AppSumo, where it ran a lifetime deal and has accumulated real review history. Across roughly 71 verified AppSumo reviews it sits at about 3.89 out of 5, which is a useful honest signal: customers love the AI features, clean interface, and responsive support, while some report bugs, occasional slow performance, and limited contact management. That's a fair picture of a young but actively developed product. Mechanically, the standout capabilities are built around running outreach safely at volume. Prosp rotates between multiple connected LinkedIn accounts so you can spread activity and scale without hammering a single profile, and every connected account gets its own free residential proxy so the activity looks native rather than like it's coming from a data center. A unified inbox pulls every conversation across every account into one place, so reps aren't logging in and out of separate profiles all day. You build multi-step sequences mixing AI-personalized text and automated voice notes, and the lead finder plus Chrome extension handle sourcing and importing prospects. The design intent is clear throughout, this is for someone managing outreach for several clients or running prospecting across a team of reps. Pricing is per account, which is the model you have to reason about carefully. The standard rate is $79 per account per month, dropping to $59 per account if you pay annually, and there's a lower entry tier reported around $29 to $39 depending on billing. Every level includes unlimited AI personalization, unlimited campaigns and contacts, full feature access, and the free proxies, so there's no feature gating, the variable is purely how many accounts you connect. There's a free trial, custom enterprise pricing, and you can book a setup call to get going. One thing AppSumo reviewers flagged is that additional sender seats beyond your base plan carry their own cost, so read the per-account math before you commit. The strengths are real. Voice note automation, especially with voice cloning, is a differentiator most LinkedIn tools simply don't have, and it can genuinely lift reply rates because a voice note feels personal in an inbox full of templated text. The per-account proxies and rotation meaningfully reduce the restriction risk that plagues aggressive LinkedIn automation. And flat per-account pricing with everything unlocked is easy to reason about versus tools that nickel-and-dime features across tiers. The weaknesses are just as real. Per-account pricing adds up fast once you're running many seats, so a team of ten is a meaningful monthly bill. It's locked to LinkedIn, so it isn't a general multi-channel outreach platform, and if your motion needs email plus LinkedIn plus calls in one tool, this isn't it. Aggressive automation on LinkedIn always carries some account-ban risk no matter how careful the proxy setup, that's the nature of the platform, not a Prosp-specific flaw. And the reported bugs and contact-management limits from reviews mean you should expect some rough edges. Public contact details are also thin beyond a Calendly link, though founder Yann Dine is reachable on X. Who should use it. Lead-gen agencies running outreach for multiple clients, sales teams scaling LinkedIn prospecting across several reps, founders booking demos through personalized cold outreach, and recruiters sourcing candidates at volume. Who should skip it. Solo operators sending a handful of messages a week who don't need rotation or proxies, teams that want true multi-channel outreach in one platform, and anyone uncomfortable with the inherent ban risk of automated LinkedIn activity. In a crowded LinkedIn automation field, Prosp's voice-note angle and agency-first architecture are what justify a look.
