Let’s be honest—6sense is a beast. It’s packed with intent data, predictive AI, and account-based marketing features. But damn, it’s also pricey, bloated, and sometimes way more than you actually need. I’ve tested tons of B2B Lead Generation Tools and platforms that offer similar benefits—some even better depending on your goals.

So if you’re ready to ditch the complexity (and the 5-figure bill), here are the best 6sense alternatives worth using in 2025. All tested, all honest.

1. ZoomInfo – The Enterprise Go-To

What it is: Giant B2B leads database with intent data, firmographics, contact info, and native sales tools.

What I liked:

• The data coverage is massive.
• Intent tracking is super accurate.
• Works great with SalesOS and Chorus for pipeline insight.

What I didn’t like:

• UI is clunky.
• Super expensive—really only worth it for large teams.
• You’ll need someone to own the tool.

Pricing: Custom (aka, expensive af).

Verdict: If you want a 6sense alternative with real-time business leads, contact data, and intent, ZoomInfo is solid. But only go for it if your budget isn’t a concern.

2. RocketReach – Quick Contact Data Without the Bloat

What it is: Lightweight lead generation database that helps you find emails, phone numbers, and social profiles fast.

What I liked:

• Easy to use, fast lookups.
• Accurate B2B emails.
• Great for LinkedIn prospecting.

What I didn’t like:

• No intent data or AI scoring.
• No sequencing or workflows.

Pricing: From $53/mo.

Verdict: RocketReach is no 6sense when it comes to predictive insights—but if you just need verified contact info for outbound, it’s cheap, simple, and effective.

3. Kaspr – Perfect for LinkedIn Prospecting

What it is: Chrome extension that grabs contact info (email + phone) directly from LinkedIn profiles.

What I liked:

• Works like magic on Sales Navigator.
• Phone numbers are super reliable.
• Real-time data, not outdated scraps.

What I didn’t like:

• No intent data or account tracking.
• Database is smaller compared to 6sense or Apollo.

Pricing: Free plan available, then from €30/month.

Verdict: Kaspr is way more nimble than 6sense. Not an ABM machine, but awesome for outbound reps who live on LinkedIn.

4. LeadIQ – Real-Time Prospecting + CRM Sync

What it is: Combines B2B lead capture, enrichment, and outbound email tools into one sleek system.

What I liked:

• Real-time LinkedIn + company scraping.
• Smart integrations with Salesforce + HubSpot.
• Built-in cold email features.

What I didn’t like:

• No predictive insights like 6sense.
• Data quality is decent, but not elite.

Pricing: Free limited plan, then from $75/mo.

Verdict: 6sense gives you predictive intent, LeadIQ gives you real-time, actionable contacts. Use it if you want faster outbound, not complex ABM workflows.

5. Apollo.io – My Personal Favorite

What it is: Full-stack B2B lead generation platform with a massive database, built-in email sequencer, CRM features, and even basic intent signals.

What I liked:

• 275M+ contacts with solid filters.
• Outreach built in—no need to bounce between tools.
• Enrichment, scoring, job changes, buying signals.

What I didn’t like:

• UI gets a bit clunky when managing large lists.
• Intent data isn’t as deep as 6sense.

Pricing: Free plan, then paid from $49/month.

Verdict: If you want 80% of what 6sense does at 10% of the cost, go with Apollo. For real. It’s the best all-in-one B2B lead gen tool I’ve used this year.

6. SalesIntel – Great for Human-Verified Data

What it is: A high-quality B2B leads database provider with 95% human-verified data and intent insights.

What I liked:

• Interface is a bit dated.
• Pricing isn’t transparent—sales call required.

Pricing: Custom, mid-to-high tier.

Verdict: If you love the intent features of 6sense but want better raw contact data, SalesIntel nails that. It’s one of the more accurate lead generation companies I’ve used.

7. LeadSwift – Scrappy Lead Scraper With Some Magic

What it is: A lead scraping tool for local biz and niche B2B.

What it is: A desktop tool to find business leads with email, phone, and company info.

What I didn’t like:

What it is: A browser extension that grabs verified B2B emails from LinkedIn and company domains.

What I liked:

• Super simple UI.
• Great LinkedIn integration.
• Decent email accuracy.

What I didn’t like:

• No automation, no CRM sync.
• Doesn’t go deep with signals or scoring.

Pricing: Free tier, then starts at $39/month.

What it is: A mix of email finder, cold outreach platform, and drip campaign builder.

What I liked:

• All-in-one cold email workflow.

What I didn’t like:

What it is: Email extraction tool for LinkedIn and company domains with lead list building.

What I liked:

What I didn’t like:

• No intent signals or firmographic filters.

Pricing: Free plan, then starts at $49/month.

Verdict: It’s barebones, but it works. Good for clean B2B contact data, but lacks the brains of something like 6sense.

12. TaskDrive – Lead Research as a Service

What it is: A done-for-you lead generation service—they do manual prospecting for you.

What I liked:

• You’re dependent on their process.

Pricing: Custom—usually starts around $1,000/mo.

Verdict: If you’re sick of doing research yourself and don’t need the AI fluff of 6sense, TaskDrive is a legit outsourced solution.

13. LeadFuze – Smart Lead Lists + AI Filtering

What it is: B2B contact data tool with AI filtering and account-based search features.

What I liked:

What it is: Cold email automation platform with inbox rotation, smart sending, and warm-up.

What I liked:

• Send 1000s of emails safely.

• No built-in data (you’ll need your own list).
• Reporting could be better.

Pricing: From $37/month.

Verdict: Combine this with any lead source (like Apollo or GetProspect) and you’ve got a killer outreach machine. Not a lead source on its own though.

15. Brevo (formerly Sendinblue) – Good for Email Marketing, Not Leads

What it is: Email marketing + CRM platform with automation and campaign tools.

What I liked:

• Great for newsletters and email sequences.
• Simple CRM tools for small teams.
• SMS and WhatsApp marketing included.

What I didn’t like:

• No real lead generation database.
• Very B2C-focused.

Pricing: Free plan, then from $25/month.

Verdict: Don’t expect it to replace 6sense for B2B demand gen. But if you already have a list and want a budget-friendly email marketing tool, it works well.

16. Leadzai – AI Ad Optimization for SMBs

What it is: An AI ad platform that helps you create and optimize Google + Meta ads for lead generation.

What I liked:

• Built for small biz and solopreneurs.
• Suggests budgets, creatives, and targeting.
• Hands-off lead flow from paid channels.

What I didn’t like:

• No outbound or email features.
• Not ideal for enterprise sales.

Pricing: Free to start, paid based on ad budget.

Verdict: Very different vibe from 6sense. It’s not a B2B lead generation company in the traditional sense, but for paid ad leads on a budget, it’s solid.

17. Leadfeeder – Website Visitor Tracking That Works

What it is: Tracks who visits your site, even if they don’t fill out a form.

What I liked:

• You’ll still need to enrich the data to get contact info.
• Not super helpful if you don’t get traffic yet.

Pricing: Free plan, paid from $139/month.

Verdict: A solid add-on if you’re already running inbound and want to uncover anonymous visitors. 6sense does this too, but with more bells and whistles.

What it is: A B2B lead generation database with real-time email verification.

What I liked:

• Solid data quality.

19. Lead411 – Intent + Contact Data Combo

What it is: Sales intelligence platform with intent data and verified contact info.

What I liked:

• Built-in email sequences.
• US-focused data is strong.

What I didn’t like:

What it is: Combines email finder, outreach, pipeline, and CRM features.

What I liked:

• Everything lives in one place.
• Automated email flows.
• Good for small outbound teams.

What I didn’t like:

• Feels like it tries to do too much.
• Data enrichment isn’t as strong.

Pricing: Starts at $99/month.

Verdict: Like a mini version of Apollo or Outreach. Doesn’t go toe-to-toe with 6sense, but a great starter stack.

What it is: Pulls professional emails from domains and validates them.

What I liked:

• Basic—no workflows or signals.
• Only email, no phone or deep firmo data.

Pricing: Free tier, paid starts at $49/month.

Verdict: A great lead generation tool if you’re just building lists and need quick email discovery. But not in the same class as 6sense in terms of depth.

22. Coldlytics – Human-Verified Lead Research

What it is: Request-based lead research, manually verified by their team.

What I liked:

• Crazy specific lead targeting (e.g., “chiropractors in Texas with Yelp reviews”).
• Fully human-researched.
• Cold email–ready lists.

What I didn’t like:

• Not instant—you wait for results.
• Small team = not for scale.

Pricing: Pay-as-you-go model.

Verdict: Perfect if you need high-precision business leads and don’t trust scraped tools. Quality over quantity.

23. Seamless.ai – AI-Powered Contact Search Engine

What it is: A B2B contact platform using “real-time search” to find accurate leads.

• Data can still be hit-or-miss.
• Aggressive upsells and marketing.

Pricing: Free trial, then starts at $147/month.

Verdict: Offers a lot of bang for the buck if you don’t mind sorting through a few duds. Not as predictive or signal-rich as 6sense though.

24. LeadsGorilla – Local Lead Hunter for Agencies

What it is: Built to help local marketers and agencies find leads from platforms like Google My Business.

What I liked:

• Unique niche—local lead gen.
• Pulls review data, contact info, social signals.
• Great for service biz targeting.

What I didn’t like:

• Not really built for SaaS/B2B targeting.
• Clunky desktop UI.

What it is: A Chrome extension + platform to pull direct dials and emails.

What I liked:

• Clean, verified data.
• Integrates with CRMs.

What I didn’t like:

• Gets expensive fast.
• Limited filters on lower tiers.

Pricing: Free tier, then $39+/mo.

Verdict: More of a ZoomInfo alt than a 6sense alt. But if you just want accurate contact info fast, Lusha delivers.

26. Clay – Smart Lead Workflows & Automation

What it is: A spreadsheet-style lead enrichment + automation platform with insane flexibility.

What I liked:

• Combine 30+ data sources (LinkedIn, Clearbit, etc.)
• Auto enrich, score, and trigger workflows.
• Great for technical teams.

What I didn’t like:

• Bit of a learning curve.
• No built-in contact data—needs plug-ins.

Pricing: Starts at $149/mo.

Verdict: Clay can become your custom 6sense… if you’re down to build it. Total hacker’s dream for lead ops.

• Nice Chrome extension.

What I didn’t like:

• Kinda shallow data.
• Limited outreach or automation features.

Pricing: Starts at $21/month.

Verdict: Decent add-on if you’re doing tech-based targeting. Not close to 6sense in the predictive space.

28. Dun & Bradstreet (DNB) – Enterprise-Grade Company Data

What it is: Massive database of verified company records, risk scores, and buying intent.

What I liked:

• Insane global coverage.
• Trusted for enterprise deals.
• Tons of firmographic + financial insights.

What I didn’t like:

• Old-school UI.
