B2B prospecting is the part of sales that AI genuinely changed — not by replacing the rep, but by collapsing the hours between "who should I talk to?" and "a message they'll actually open." The catch is the category is flooded: half the "AI prospecting" tools are a GPT wrapper with a pricing page. We went through the sales tools in our directory, verified the prices at checkout, and kept the ones that do a specific job well.
What AI actually does in prospecting
Strip the marketing away and AI prospecting tools do one of four things: find the right people, enrich what you know about them, write the first touch, and run the sequence. Most tools cover one or two. Buy for the gap in your own process, not the longest feature list.
The tools, by job
LinkedIn outreach
- Dux-Soup — from $14.99/mo (verified). The veteran LinkedIn automation tool: visits, connection requests and message sequences on autopilot, with a free trial before you commit. Best for SDRs who run LinkedIn as a primary channel.
- Salee — free inbox tier; Growth $19/mo, Outreach $39/mo. A smart LinkedIn inbox with hot-lead detection and AI replies, stepping up to automated invites and sequences. The free tier is the cheapest way to see whether AI-written LinkedIn replies land for your market.
Sequencing and engagement
- Reply.io — from $59/mo (verified). Multichannel sequences (email, LinkedIn, calls) with AI-assisted copy and deliverability tooling. The most complete engagement layer on this list; priced for teams that will use all of it.
Personalized first touch
- MailMentor — from $9/mo (verified). AI-written personalized sales messages with a built-in prospect finder (100 contact scrapes a month on the entry plan). The cheapest verified entry on the list — good for solo founders doing their own outbound.
A realistic stack, priced
For one person doing outbound: Salee's free inbox + MailMentor at $9 gets you AI-written LinkedIn and email first-touches for under $10 a month. For a small SDR team that needs sequencing: Dux-Soup ($14.99) for LinkedIn volume plus Reply.io ($59) for multichannel — about $74 per seat, verified at each checkout. Both stacks assume you already have a data source; none of these replaces a proper contact database.
What to watch for
- LinkedIn's limits are real. Automation tools work inside LinkedIn's rate caps; pushing past them risks restrictions on the account doing the sending. Start conservative.
- "AI personalization" varies wildly. Test any tool's output on five real prospects before you buy a seat. Generic output at scale is worse than no outreach.
- Seat pricing compounds. Every tool above is per user. A five-person team on the full stack is closer to $370/mo than $74.
