If you sell to businesses, you've probably noticed your inbox and LinkedIn feed filling up with pitches for an "AI SDR" that will supposedly replace your outbound team. Some of that is real: a new wave of tools now researches prospects, writes personalized messages, and manages replies with much less manual work than a spreadsheet and a mail merge tool. Some of it is also hype — a few vendors promised a full human replacement in 2024-2025 and quietly walked that back once customers tried it. This guide looks at eight tools that are actually live and in use today, from six-figure-a-year "digital employee" platforms down to $49/month tools a solo founder can run alone.
The short version: if you have real budget and want a fully autonomous outbound motion, look at 11x or Artisan. If you want a flexible research/enrichment engine you wire up yourself, Clay is the industry default. For lighter, cheaper prospecting, Lev8, Agent Jesse and Pebbles AI are built for smaller teams. And if your whole motion lives on LinkedIn specifically, Fuzzy AI and Sherloq are purpose-built for that channel.
11x — the "digital employee" for enterprise outbound
11x splits the job into two named agents — Alice for outbound, Julian for inbound — and researches prospects across 50+ data sources before generating outreach. It's SOC-2 compliant and backed by a16z and Benchmark, and it's priced like hiring someone: reportedly $36,000-$68,000 a year, with no public pricing page.
Good for: growth-stage and enterprise RevOps teams that can justify replacing (or augmenting) a headcount line with a subscription. Limits: the "fully autonomous AI SDR" narrative has cooled industry-wide since 2024 — treat it as a strong assist, not a guaranteed hire replacement, and the published case-study numbers are single-customer claims, not verified averages.
Artisan — the more affordable 11x alternative
Artisan (its agent is named Ava) automates enrichment, multi-channel sequencing and reply handling, with continuous A/B testing of its own messaging. It integrates with HubSpot, Salesforce and ZoomInfo. Custom pricing by lead volume lands in a reported $2,000-$5,000/month range — well under 11x's enterprise contracts.
Good for: startups and SMBs who want AI-assisted outbound without an 11x-sized contract. Limits: same industry-wide caveat as 11x on the "full replacement" pitch, and there's no public pricing page — you'll need a sales call to get a real number.
Clay — the enrichment engine sophisticated GTM teams build on
Clay is less a finished "AI SDR" and more a spreadsheet-native research engine: it stacks 200+ data providers in a "waterfall enrichment" pattern so you can build custom lead-research logic without engineering help. It's reportedly used internally by OpenAI, Anthropic and Mistral AI for their own GTM tooling. Pricing starts free (500 actions/month) and scales to $167+/month (Launch) or $446+/month (Growth), with credit-based billing throughout.
Good for: GTM, sales and RevOps teams who want to design their own enrichment/outreach logic rather than accept a black box. Limits: credit-based pricing can get expensive fast at real usage volume, and it takes more setup work than a plug-and-play tool.
Lev8 — real-time web research instead of a stale database
Lev8 sends AI agents to search the live web for prospects instead of querying a static, purchased database, then runs multi-channel outreach across email, LinkedIn, WhatsApp and SMS with auto-generated battle cards. Free tier gives 500 credits/month; paid tiers run $49 (Starter, 5K credits) to $499/month (Scale, 65K credits).
Good for: growth and sales teams doing multi-channel outbound who want fresher data than a static list. Limits: credit pricing is less predictable than a flat subscription, and the "10x, -60% cost" performance figures are self-reported.
Agent Jesse — the generous free tier for early-stage teams
Agent Jesse also searches the live internet rather than a fixed database, and lets you query in plain English ("find me Series A fintech founders in Berlin") instead of building filter combinations. It enriches each prospect with 50+ data points. The free tier is unusually generous: 1,000 credits and 50 company searches/enrichments per day, no card required. Paid plans start around $9/month.
Good for: founders and small SaaS/IT-services sales teams who want to try real AI prospecting before paying anything. Limits: native CRM integrations (Zapier, HubSpot, Salesforce) are still listed as "coming soon" rather than live, and its email-accuracy and user-count claims aren't independently verified.
Pebbles AI — lead gen, outreach and inbox in one
Pebbles AI bundles lead generation, outreach sequencing and an AI-managed inbox into a single system, and lists Google, Cisco and HP as customers. It's CASA Level II and Microsoft 365 certified. Pricing runs from £49/month (Professional, 400 leads) to £3,499/month (Enterprise, 15,000 leads).
Good for: B2B sales teams that want to consolidate lead-gen, outreach and analytics into one tool instead of stitching several together. Limits: its 60%/51%-style performance claims are self-reported, and the higher tiers get expensive — this only pays off if you actually want everything under one roof.
Fuzzy AI — LinkedIn outreach that warms up before it pitches
Fuzzy AI is built specifically for LinkedIn: instead of cold-DMing immediately, it has your account engage with a prospect first (likes, comments) before sending an outreach message, which helps avoid the platform bans that come from pure-volume tools. Pricing runs Starter $149/month to Scale $599/month, with named customers including Google and MongoDB.
Good for: B2B teams whose prospects are genuinely reachable on LinkedIn and want a slower, safer cadence than a spam-style tool. Limits: reply-rate numbers are self-reported and unaudited, pricing is steep for a solo user, and it stays dependent on LinkedIn's ever-changing rules.
Sherloq — turns LinkedIn signals into timed outreach
Sherloq watches for LinkedIn signals — job changes, competitor interactions, relevant posts — and auto-drafts personalized outreach the moment they happen, integrating with 50+ tools including HubSpot, Salesforce and Apollo. Pricing is €69-179/month, notably cheaper than enterprise sales-intelligence suites.
Good for: B2B teams selling to buyers who are active and visible on LinkedIn. Limits: value depends entirely on how active your specific targets are on LinkedIn, its time-saved and meeting-uplift figures are vendor-reported, and it doesn't cover other channels.

None of these tools fully replaces a sales team's judgment, and every vendor's performance numbers in this space should be read as marketing claims until you verify them with your own pilot. But the actual mechanics — real-time web research instead of stale databases, multi-channel sequencing, and AI-drafted personalization — are genuinely useful, and the price range here (from free to enterprise) means there's a realistic entry point whether you're a solo founder or a RevOps team with a real budget.
