6sense Review 2026: Powerful ABM Platform or Overpriced Black Box? (Honest Take)

ยท 7 min read

Founder, marketbetter.ai

6sense is one of the most ambitious platforms in B2B sales tech. It promises to use AI and intent data to predict which accounts are in-market to buy โ€” before they ever fill out a form. The pitch: stop guessing, start selling to accounts that are already researching your category.

In theory, it's transformative. In practice? The reality is more complicated. 6sense delivers genuine value for enterprise ABM teams with the budget and patience to implement it. But for everyone else, the steep pricing, complex setup, and opaque algorithms create friction that can outweigh the benefits.

We analyzed G2 and TrustRadius reviews, talked with teams using 6sense, and compared it against modern alternatives. Here's what holds up and what doesn't.

What 6sense Does Wellโ€‹

1. Intent Data at Scaleโ€‹

6sense's core strength is processing massive amounts of intent data to identify accounts showing buying behavior:

  • 500B+ intent signals analyzed across channels
  • Keyword-level tracking โ€” see which topics target accounts research
  • Buying stage predictions โ€” AI categorizes accounts into stages (Awareness, Consideration, Decision, Purchase)
  • Bombora integration plus proprietary first-party signals

For enterprise ABM teams, this means prioritizing outreach based on where accounts sit in the buying journey rather than guessing. When it works, it genuinely shortens sales cycles.

2. Predictive Buying Stagesโ€‹

6sense's AI models predict which accounts are most likely to convert and what stage they're in. This powers:

  • Account scoring that goes beyond basic firmographic fit
  • Segment building based on predicted intent + ICP match
  • Orchestration โ€” trigger different campaigns based on buying stage

The prediction models get better over time as they learn from your closed-won data, which means long-term users see compounding value.

3. Advertising Integrationโ€‹

6sense's display advertising capabilities let you:

  • Retarget identified accounts across the web
  • Run ABM campaigns targeting specific account lists
  • Measure ad influence on pipeline
  • Sync audiences to LinkedIn, Google, and programmatic networks

This integration between intent data and advertising is genuinely useful for coordinating marketing and sales efforts around the same accounts.

4. Free Tier Existsโ€‹

Unlike most enterprise platforms, 6sense offers a free Community plan with:

  • Basic company data
  • Limited intent signals
  • Contact search (with caps)
  • Chrome extension for prospecting

It's not full-featured, but it lets small teams test the waters without a sales call.

Where 6sense Falls Shortโ€‹

1. Pricing Is Enterprise-Onlyโ€‹

Despite the free tier, 6sense's paid plans are firmly enterprise-priced:

  • Team plan: Estimated $30,000-$50,000/year (not publicly listed)
  • Growth plan: $50,000-$100,000+/year
  • Enterprise: $100,000+/year for the full platform
  • Advertising costs are additional โ€” and escalate quickly with refined targeting
  • Multi-year contracts are standard

For SMBs and mid-market companies, this pricing is a non-starter. You're paying enterprise ABM platform prices before you know if intent data will work for your specific market.

2. The Black Box Problemโ€‹

This is the most common complaint from 6sense users across review platforms:

  • Intent scores feel opaque โ€” "why does this account show Decision stage?"
  • Hard to validate predictions โ€” you can't easily see what signals drove a score
  • Trust requires faith โ€” teams either believe the AI or don't, with limited visibility in between
  • False positives waste SDR time โ€” accounts flagged as "in-market" that aren't actually buying

One TrustRadius reviewer noted: "Exclusions are too simple. There's no logic for two conditions, either/or statements. This results in accounts missing from our ICPs."

When your $50K+/year platform tells an SDR to call an account and the prospect says "we're not looking at anything right now," trust erodes quickly.

3. Steep Learning Curveโ€‹

6sense is not a "log in and go" platform:

  • Implementation takes months โ€” not days or weeks
  • Requires dedicated admin โ€” often a full-time RevOps resource
  • Advanced features demand training โ€” most teams underutilize the platform significantly
  • Segment building is complex โ€” the flexibility is a double-edged sword

Teams without RevOps support often end up using 6sense as an expensive prospecting database rather than the AI-powered ABM orchestration tool they bought.

4. Company-Level, Not Action-Levelโ€‹

Like ZoomInfo, 6sense excels at telling you WHICH accounts to pursue but falls short on telling SDRs WHAT TO DO:

  • No daily SDR playbook โ€” reps get account lists and scores, not prioritized task lists
  • No "call this person, say this" workflow โ€” SDRs still figure out the approach themselves
  • No real-time engagement โ€” no AI chatbot intercepting visitors as they browse
  • No unified execution โ€” teams still need separate tools for email, calling, and chat

The gap between "this account is in-market" and "this SDR books a meeting" is still largely manual.

5. Website Visitor ID Is Company-Levelโ€‹

6sense identifies companies visiting your website, not specific people:

  • Company-level resolution only โ€” "Acme Corp visited" but not "Jane from Acme"
  • No person-level identification for known contacts revisiting your site
  • No real-time alerts for individual visitor sessions
  • Relies on IP-to-company mapping with inherent accuracy limits

For account-based teams this is adequate. For teams that want to know the specific person researching your product, it's a gap.

Who 6sense Is Best Forโ€‹

Enterprise ABM teams (500+ employees) who:

  • Run coordinated marketing + sales motions against named accounts
  • Have budget for $50K+/year platform spend
  • Have RevOps resources to implement and manage
  • Sell high-ACV deals ($50K+) where intent data ROI is clear
  • Need advertising + intent data integration

6sense is NOT ideal for:

  • SMBs or mid-market companies (pricing is prohibitive)
  • Teams that need quick time-to-value (months-long implementation)
  • SDR teams that need daily playbooks and task prioritization
  • Companies wanting person-level visitor identification
  • Teams without dedicated RevOps support

Best forEnterprise ABMSMB-Mid Market SDR teams

6sense asks: "Which accounts in our TAM are showing intent?"

MarketBetter asks: "Who's on our website right now, and what should we do about it?"

Both questions matter. But for most B2B teams, the second question drives faster pipeline because you're acting on first-party buying behavior โ€” not third-party topic signals.

The Bottom Lineโ€‹

6sense is a legitimate enterprise ABM platform. The intent data is real, the predictive models improve over time, and the advertising integration is unique. For large organizations running coordinated ABM plays across marketing and sales, it delivers value that's hard to replicate.

But the market has moved. In 2026, the choice isn't just "buy 6sense or go without intent data." New platforms deliver intent signals โ€” from your actual website traffic โ€” combined with SDR execution tools, at a fraction of the cost. The question is whether topic-level intent from third-party data is worth 10x more than page-level intent from your own website visitors.

For most teams under 500 employees: it's not. The money you'd spend on a 6sense contract could fund your entire sales tech stack โ€” CRM, visitor ID, email sequences, dialer, and AI chatbot โ€” with budget left over.

Our recommendation: If you're an enterprise with an established ABM program and the budget to support it, 6sense is a strong option. For everyone else, start with your own website traffic data. The 98% of visitors leaving anonymously are a more actionable signal than third-party topic intent โ€” and tools that capture those signals cost a fraction of 6sense's annual contract.

Apollo.io Review 2026: Is It Still Worth It for SDR Teams? (Honest Take)

ยท 6 min read

Founder, marketbetter.ai

Apollo.io has become one of the most popular sales platforms for outbound teams. With 275M+ contacts, built-in email sequencing, and a generous free tier, it looks like a no-brainer for SDR teams building their tech stack.

But after talking with dozens of sales teams who use Apollo daily, the picture is more nuanced than the marketing suggests. Some teams swear by it. Others hit walls โ€” credit limits, data accuracy gaps, and deliverability problems โ€” that make them start looking for alternatives within months.

Here's our honest take on Apollo in 2026: what it does well, where it falls short, and who should (and shouldn't) use it.

What Apollo.io Does Wellโ€‹

1. The All-in-One Value Propositionโ€‹

Apollo's strongest pitch is that you don't need a separate data provider, sequencing tool, and dialer. Everything lives under one roof:

  • Contact database (275M+ contacts, 60M+ companies)
  • Email sequences with multi-step automation
  • Built-in dialer for cold calling
  • LinkedIn integration via Chrome extension
  • Basic CRM functionality

For small teams who'd otherwise juggle ZoomInfo ($15K+/yr) + Outreach ($100+/seat/mo) + a dialer, Apollo consolidates that into one platform starting at $49/month.

2. Aggressive Pricingโ€‹

Apollo deliberately undercuts competitors. Their 2026 pricing:

PlanPrice (Annual)Credits/MonthKey Features
Free$0100Basic search, 250 emails/day
Basic$49/mo900Sequences, intent filters
Professional$79/mo1,200Dialer, advanced reports
Organization$119/mo2,400Data enrichment API, SSO

Compared to ZoomInfo's $15K+ annual minimum or 6sense's $30K+ enterprise pricing, Apollo is accessible for startups and SMBs.

3. Solid Chrome Extensionโ€‹

Apollo's Chrome extension works well on LinkedIn, letting SDRs prospect without leaving Sales Navigator. One-click enrichment, direct-to-sequence, and contact data overlay are genuinely useful in daily workflows.

Where Apollo Falls Shortโ€‹

1. Data Accuracy Is a Real Problemโ€‹

This is Apollo's Achilles' heel. Multiple G2 reviewers and teams we've spoken with report:

  • Email bounce rates of 15-25% on Apollo-sourced contacts (industry standard should be under 5%)
  • Outdated job titles โ€” people who changed roles 6-12 months ago still listed at old companies
  • Weak international data โ€” EMEA and APAC coverage is significantly worse than North America
  • Phone numbers often wrong โ€” direct dials frequently route to main company lines

When your sequence tool and data source are the same platform, bad data doesn't just waste credits โ€” it tanks your email sender reputation.

2. The Credit System Creates Frictionโ€‹

Apollo's credit model sounds generous until you hit the walls:

  • Free plan: 100 credits/month (barely enough to test)
  • Export limits: Can only select 25 records at a time for export
  • Credit burns: Revealing emails and phone numbers costs separate credits
  • Enrichment costs extra at the Organization tier

Teams doing serious outbound (500+ prospects/month) burn through credits fast and either upgrade or start rationing, which defeats the purpose of an "all-in-one" tool.

3. Deliverability at Scale Is Challengingโ€‹

Running cold email campaigns through Apollo at volume introduces problems:

  • Shared sending infrastructure means your reputation is partially tied to other Apollo users
  • No built-in email warmup (you need a separate tool like Instantly or Mailreach)
  • Sequence management gets messy โ€” the UI isn't designed for teams running 10+ active campaigns simultaneously
  • Reply handling is basic compared to dedicated engagement platforms like Outreach or Salesloft

4. No Website Visitor Identificationโ€‹

Apollo tells you who's in its database. It doesn't tell you who's visiting your website right now. This is a critical gap for inbound-assisted outbound:

  • No reverse IP lookup
  • No real-time visitor alerts
  • No integration with visitor identification tools out of the box

If someone visits your pricing page three times this week, Apollo has no idea. You're relying entirely on cold outbound when warm signals exist.

5. No Daily Playbook or Prioritizationโ€‹

Apollo gives you a database and sequencing tools, but it doesn't tell your SDRs what to do next. There's no:

  • Daily task prioritization based on intent signals
  • Automated lead scoring that factors in website behavior
  • Playbook-style workflow ("Call this person first because they visited pricing yesterday")

SDRs still have to figure out their own priorities every morning, which is exactly the productivity problem modern sales tools should solve.

Who Apollo Is Best Forโ€‹

Small outbound-only teams (1-5 SDRs) who:

  • Primarily do cold outbound (no inbound pipeline)
  • Operate in North America (data is strongest here)
  • Need an affordable all-in-one to start prospecting
  • Can tolerate higher bounce rates in exchange for lower cost
  • Don't need website visitor identification

Apollo is NOT ideal for:

  • Teams with meaningful inbound traffic (no visitor ID)
  • Companies needing high data accuracy (healthcare, financial services)
  • Large SDR teams (10+) who need advanced prioritization
  • Teams doing both inbound and outbound (need signal-based workflows)

Apollo vs. MarketBetter: A Different Philosophyโ€‹

Apollo and MarketBetter solve different problems:

CapabilityApolloMarketBetter
Contact database275M+ contactsFocused on your actual visitors
Website visitor IDโŒโœ… Company + person-level
Daily SDR playbookโŒโœ… Prioritized task list
Intent signalsBasic (keyword tracking)Website behavior + engagement
Email sequencesโœ… Built-inโœ… Hyper-personalized
Smart dialerBasic power dialerโœ… Warm call routing
AI chatbotโŒโœ… Instant visitor engagement
ApproachCold outbound at scaleWarm outbound from signals

Apollo's philosophy: Give SDRs a massive database and let them blast outreach at volume.

MarketBetter's philosophy: Show SDRs exactly who's interested and what to do about it. Fewer contacts, but warmer and more likely to convert.

The Bottom Lineโ€‹

Apollo is one of the best value propositions in sales tech for teams that need affordable, all-in-one cold outbound tooling. The free tier is genuinely useful for testing, and the pricing undercuts legacy vendors by 70-80%.

But "affordable" and "effective" aren't the same thing. Data accuracy issues, credit limitations, and the total absence of inbound signal processing mean Apollo-sourced outbound often converts at lower rates than signal-driven approaches.

If your team generates any meaningful website traffic, you're leaving pipeline on the table by using a tool that can't see those visitors. The 98% of traffic that leaves without filling out a form? Apollo has no idea they exist.

Our recommendation: Apollo is a solid starting point for early-stage outbound teams. But as you grow and start generating inbound traffic, you'll need to either layer on visitor identification tools (adding cost and complexity) or switch to a platform that connects signals to action from day one.

ZoomInfo Review 2026: Is $15K+/Year Still Justified? (Honest Assessment)

ยท 6 min read

Founder, marketbetter.ai

ZoomInfo is the 800-pound gorilla of B2B data. With the largest contact and company database on the market, intent data, and a full engagement suite, it's the default choice for enterprise sales teams.

But "default" doesn't mean "best for everyone." ZoomInfo's pricing starts at $14,995/year with annual contracts, auto-renewal clauses, and a credit system that makes costs hard to predict. For mid-market and SMB teams, the ROI math gets shaky fast.

We dug into real G2 reviews, talked to teams who use (and left) ZoomInfo, and compared it against the new generation of sales tools. Here's what we found.

What ZoomInfo Does Wellโ€‹

1. The Gold Standard for B2B Dataโ€‹

Credit where it's due: ZoomInfo has the most comprehensive B2B database available. Period.

  • 100M+ business professionals with verified contact info
  • 14M+ company profiles with firmographic data
  • Phone number accuracy is best-in-class (direct dials, not main lines)
  • Org charts and reporting structures
  • Technographic data โ€” what tools companies use

For enterprise teams selling into large accounts, this depth of data is genuinely hard to replicate elsewhere. The org charts alone justify the price for strategic account-based selling.

2. Intent Data (Via Bombora Integration)โ€‹

ZoomInfo's Bombora-powered intent data shows you which companies are actively researching topics relevant to your product. This lets teams:

  • Prioritize accounts showing buying signals
  • Time outreach to coincide with research activity
  • Score leads based on intent + firmographic fit

The intent data isn't perfect (it's topic-level, not page-level), but it's better than flying blind.

3. WebSights (Visitor Identification)โ€‹

ZoomInfo's WebSights feature identifies companies visiting your website. It's company-level identification โ€” you see "Acme Corp visited your pricing page" but not which specific person. Still useful for account-based teams who can route to the right rep based on account ownership.

4. Robust API and Integrationsโ€‹

ZoomInfo connects with everything: Salesforce, HubSpot, Outreach, Salesloft, Marketo, and dozens more. The API is well-documented and lets RevOps teams automate enrichment workflows at scale.

Where ZoomInfo Falls Shortโ€‹

1. Pricing That Locks You Inโ€‹

ZoomInfo's pricing is the single biggest complaint across review platforms:

  • Minimum $14,995/year โ€” no monthly plans, no "starter" tier
  • Annual contracts only โ€” with 60-day cancellation windows
  • Auto-renewal with 20% increases โ€” reported by multiple G2 reviewers
  • Credit-based usage โ€” heavy prospecting teams blow through credits quickly
  • Add-ons cost extra โ€” intent data, enrichment, and advanced features are often separate line items

One G2 reviewer from a small business reported being quoted $25,000/year. For teams under 50 employees, this is a hard pill to swallow when competitors like Apollo offer similar (though less accurate) data for $49/month.

2. Steep Learning Curveโ€‹

ZoomInfo is powerful, but it's not intuitive. Teams frequently report:

  • Weeks of onboarding before SDRs use it effectively
  • Advanced features go unused โ€” most teams only scratch the surface (search + export)
  • The UI feels enterprise-heavy โ€” designed for power users, not quick daily workflows

If your SDRs are spending 30 minutes learning to build a search filter, that's 30 minutes they're not selling.

3. International Data Gapsโ€‹

Despite the massive database, ZoomInfo's coverage outside North America has real limitations:

  • EMEA data accuracy drops significantly โ€” especially for mid-market companies
  • APAC coverage is thin โ€” many contacts are stale or missing
  • GDPR compliance adds friction โ€” EU-based prospects may not be available depending on your configuration

For US-focused teams this isn't a problem. For global sales orgs, it's a material weakness.

4. Company-Level, Not Action-Levelโ€‹

ZoomInfo tells you WHO (contacts, accounts, intent signals). But it doesn't tell you WHAT TO DO:

  • No daily SDR playbook โ€” reps still build their own task lists
  • No automated prioritization โ€” intent signals exist but aren't turned into specific actions
  • No "call this person because they visited pricing" workflow
  • No AI chatbot to engage visitors in real-time

You're paying premium prices for data, but the "last mile" โ€” turning that data into meetings โ€” is still manual.

5. No Built-in Multi-Channel Executionโ€‹

ZoomInfo added engagement tools, but they're not the core product:

  • Email sequencing exists but most teams use Outreach/Salesloft instead
  • No smart dialer with warm-call routing
  • No AI-powered email personalization at the per-contact level
  • No unified workflow that combines data + signals + execution

Teams end up using ZoomInfo for data and 2-3 other tools for execution โ€” which means more cost, more complexity, and more places for leads to fall through cracks.

Who ZoomInfo Is Best Forโ€‹

Enterprise sales teams (100+ employees) who:

  • Sell into large, named accounts in North America
  • Have budget for $15K+/year data spend
  • Need deep org charts and direct dials for strategic selling
  • Have RevOps resources to manage the platform and integrations
  • Already use Outreach/Salesloft for engagement

ZoomInfo is NOT ideal for:

  • SMBs under $5M ARR (pricing is prohibitive)
  • Teams that need a unified data-to-action workflow
  • Global sales teams (international data is weak)
  • Companies wanting real-time visitor identification at the person level

ZoomInfo's approach: Be the world's best B2B database and let you figure out the execution.

MarketBetter's approach: Combine signals, data, and execution into one workflow so SDRs know exactly what to do every morning.

The Bottom Lineโ€‹

ZoomInfo earns its reputation for data quality. If you're an enterprise team doing strategic account-based selling into Fortune 500 companies in North America, the database depth is hard to beat.

But the sales tech landscape has shifted. In 2020, paying $15K+/year for a database made sense because there weren't alternatives. In 2026, teams have options that combine data + signals + execution for a fraction of the cost โ€” and those integrated platforms often outperform the "best data + separate tools" stack.

The question isn't whether ZoomInfo has good data. It does. The question is whether you need a $15K+ database when 98% of your website visitors are anonymous, your SDRs lack a daily playbook, and cheaper tools can handle both data and execution.

Our recommendation: If you're already on ZoomInfo and it's embedded in your enterprise workflows, it's hard to rip out. But if you're evaluating for the first time, or if your contract is up for renewal, test a signal-driven alternative before signing another annual agreement.


See what ZoomInfo can't show you. Book a demo to see real-time visitor identification, daily SDR playbooks, and the full MarketBetter workflow โ€” all without a $15K annual contract.
