5 Best Mattermark Alternatives for B2B Enrichment in 2026

Mattermark shut down in 2017. It was acquired by FullContact for less than $500K after raising over $17 million from Andreessen Horowitz, NEA, and Foundry Group. Common stockholders received nothing.

If you're searching for “Mattermark alternatives,” you already know the platform is gone. What you need is a modern B2B enrichment tool that does what Mattermark promised — and actually delivers it.

Mattermark tracked company growth signals, funding data, and firmographics to help sales teams identify high-potential accounts. In 2026, the best replacements go much further — verified contacts, multi-provider waterfall enrichment, intent signals, and outreach sequences in one platform.

This guide compares the 5 best Mattermark alternatives ranked for B2B prospecting teams. Each has been evaluated on data depth, contact enrichment accuracy, pricing, and outreach capabilities.

What Happened to Mattermark?

Mattermark was founded in 2012 as a startup intelligence platform. It aggregated data on private companies — funding rounds, headcount growth, web traffic, and app download signals — to help VCs and sales teams identify accounts worth targeting.

The company raised $17.2 million from Andreessen Horowitz, NEA, and 500 Startups. Despite strong early traction, it struggled to compete with Crunchbase, PitchBook, and CB Insights in the company intelligence space, while never building deep enough contact data to compete with ZoomInfo or Apollo.

In December 2017, Mattermark was acquired by FullContact for less than $500K in cash plus stock. According to co-founder Danielle Morrill's public statement, common stockholders received nothing. The product was shut down shortly after.

Why You Need a Mattermark Alternative in 2026

Mattermark's core value was company-level intelligence: which companies were growing fast, who just raised funding, which accounts were expanding headcount. That category has evolved significantly since 2017.

Modern B2B enrichment platforms combine what Mattermark offered with verified contact data — work emails, direct dials, LinkedIn profiles — plus behavioral intent signals that didn't exist at Mattermark's scale.

According to Gartner research, B2B contact data decays at roughly 2% per month. A contact database that isn't refreshed across multiple sources goes stale fast.

The right Mattermark alternative should solve three problems Mattermark never fully cracked:

1. Contact coverage — verified emails and mobile numbers, not just company-level data
2. Multi-source enrichment — no single provider has complete data; waterfall enrichment across 50+ sources fills the gaps
3. Outreach integration — enrichment without a way to act on the data is incomplete

#1. SyncGTM — Best Overall Mattermark Alternative

SyncGTM — waterfall enrichment from 50+ providers in a single workflow step

SyncGTM is a B2B enrichment and outreach platform that cascades contact lookups across 50+ data providers in a single waterfall step. It returns verified emails, direct dials, LinkedIn profiles, firmographics, and intent signals — 76+ data points per lead — and pushes the results directly to your CRM or outreach sequences.

Where Mattermark gave you company signals with limited contact data, SyncGTM delivers both. The waterfall approach pushes email coverage to 80-95% versus the 40-60% you get from any single-source provider.

Pros

• 50+ enrichment providers cascaded in sequence — highest coverage of any tool in this list
• 76+ data points per lead — contact info, firmographics, technographics, job change signals, and intent data in one lookup
• Integrated outreach — build email sequences and LinkedIn campaigns without switching tools
• CRM sync — push enriched data directly to Salesforce, HubSpot, or any CRM via API or native integrations
• No annual contract required — flexible credit packs at $0.05/credit with no expiration

Cons

• No built-in dialer — SyncGTM handles email and LinkedIn outreach, not cold calling directly
• Smaller brand recognition than ZoomInfo or Apollo — less useful if your team needs a vendor procurement box-tick

Best for: B2B sales and RevOps teams replacing ZoomInfo, Apollo, or any single-source enrichment tool that caps out at 60% coverage.

Pricing: Starter from $1,069/year (24,000 credits). Add-on credits at $0.05/credit, no expiration. See full pricing.

#2. Apollo.io — Best for All-in-One Prospecting and Sequences

Apollo.io is the most widely used Mattermark alternative among B2B sales teams. It combines a 275M+ contact database with built-in email sequences, a dialer, and LinkedIn integration — making it a true all-in-one prospecting platform.

Apollo replaced much of what Mattermark's early users needed: company discovery, contact lookup, and outreach in one workflow. The free plan makes it accessible for early-stage teams, while paid plans from $49/user/month unlock advanced filters and higher credit limits.

Pros

• Free plan available — 275M+ contacts, basic enrichment, and email sequences at $0
• Built-in sequences and dialer — prospect and outreach in the same platform
• Strong company filtering — industry, headcount, revenue, technology stack, and intent data filters
• Large contact database — 275M+ contacts across 65M+ companies

Cons

• Single-source data — Apollo queries its own database only, capping email coverage at 60-70% for many ICPs
• Credit bloat — forced waterfall enrichment on paid plans means a single email lookup can consume 3-10 credits
• Data quality gaps — international coverage outside North America is noticeably weaker
• Real cost is higher than headline — active outbound teams typically spend $150-$400/user/month once overages kick in

Best for: SMB and mid-market teams that want prospecting and outreach sequences in one tool and primarily work North American accounts.

Pricing: Free plan. Paid from $49/user/month (annually). Organization tier at $119/user/month.

#3. Crunchbase Pro — Best for Company and Funding Intelligence

Crunchbase Pro is the most direct successor to Mattermark's original use case. It tracks 4M+ companies, funding rounds, acquisitions, leadership changes, and investor activity — the same signals Mattermark tried to aggregate.

If your ICP includes funded startups, high-growth companies, or accounts going through M&A activity, Crunchbase Pro's coverage is unmatched for company-level intelligence. It is not a contact enrichment tool — it does not give you verified emails or phone numbers at scale — but as a company discovery layer, it remains one of the best.

Pros

• 4M+ company profiles with funding, investor, and acquisition data — the deepest free-company database available
• Funding signals — track Series A through growth rounds and target accounts right after they raise
• AI-powered search and insights — Business plan adds AI trend analysis and sector comparisons
• CRM integrations — Salesforce and HubSpot sync available on Business plan

Cons

• Weak contact enrichment — Crunchbase gives you company data; you still need another tool for verified emails and phones
• Not a prospecting platform — no built-in outreach, no sequences, no CRM enrichment automation
• Expensive for contact data — pairing Crunchbase Pro ($99/mo) with a contact tool adds significant cost versus an all-in-one platform

Best for: VCs, growth equity teams, and enterprise sales teams targeting funded companies and needing deep company intelligence above all else.

Pricing: Pro at $99/mo (or ~$588/yr). Business at $199/mo adds CRM integrations and AI agent access.

#4. ZoomInfo — Best for Enterprise Intent Data

ZoomInfo is the category leader in B2B sales intelligence — and the tool most enterprise teams replaced Mattermark with back in 2018. It combines 260M+ professional profiles with intent data, buyer intent signals, technographic data, and workflow automation.

ZoomInfo is the right choice for enterprise GTM teams that need the deepest data, the most established integrations, and can justify the cost. For everyone else, the price-to-value ratio is hard to defend in 2026 when tools like SyncGTM deliver comparable enrichment quality at 5-10% of the cost.

Pros

• 260M+ profiles and 100M+ company records — the largest proprietary B2B database
• Intent data — track which accounts are actively researching topics related to your product
• Enterprise integrations — Salesforce, HubSpot, Microsoft Dynamics, Outreach, Salesloft, and 200+ others
• Established compliance — GDPR, CCPA, and SOC 2 certifications for regulated industries

Cons

• Pricing is prohibitive — starts at $14,995/year, typically runs $30,000–$60,000+ for full-stack access
• Annual contracts required — no month-to-month, no credit packs, significant lock-in risk
• Renewal increases — 10-20% price hikes at renewal are standard; Year 2 costs more than Year 1
• Single database limitation — ZoomInfo queries its own database only, missing contacts that live in other sources

Best for: Enterprise sales and marketing teams with $30K+ annual data budgets that need intent data, compliance certifications, and deep enterprise integrations.

Pricing: Professional+ from $14,995/year. Full stack typically $30,000–$60,000+/year. Custom quotes only.

#5. Cognism — Best for GDPR-Compliant European Outreach

Cognism is a GDPR-compliant B2B data platform built primarily for European and UK-focused sales teams. Its Diamond Data tier offers phone-verified mobile numbers — a genuine differentiator when direct dials are critical to your outbound motion.

Cognism covers approximately 50M contacts with strong UK, DACH, and Benelux coverage. If Mattermark was your tool for European account targeting, Cognism is the most direct replacement for that geography.

Pros

• Phone-verified mobile numbers — Diamond Data tier verifies mobiles before delivery, claiming 98% accuracy
• Strong GDPR compliance — built for European regulatory requirements with Notified consent records
• Bombora intent data — available on higher tiers for account prioritization
• Strong European coverage — UK, Germany, France, Netherlands, and Nordics better covered than most US-first tools

Cons

• High baseline cost — platform fee of ~$15,000/year plus per-seat licenses; full Diamond Data access runs $25,000+/year
• Limited US coverage — Cognism's North American data is thinner than ZoomInfo or Apollo
• Enrichment API billed separately — heavy API usage adds $5,000–$15,000/year on top of base pricing
• No integrated outreach — Cognism provides data; you still need a separate sequencing tool

Best for: European sales teams that prioritize compliance and phone-verified mobile coverage for cold calling campaigns.

Pricing: Grow tier from ~$15,000/year. Elevate (Diamond Data) from ~$25,000/year. Custom quotes only.

How to Choose the Right Mattermark Alternative

The right tool depends on what you actually needed from Mattermark and what you need your data platform to do today. Use these decision points:

• You need full B2B enrichment with the highest contact coverage — Choose SyncGTM. The 50+ provider waterfall closes the coverage gap that killed single-source tools — waterfall contact providers consistently outperform single-source alternatives by 25-35% on hit rate.
• You need prospecting and sequences in one free or cheap tool — Choose Apollo.io. The free plan is genuinely useful for early-stage teams. Just plan for single-source coverage limitations.
• You need company intelligence and funding signals above all else— Choose Crunchbase Pro. It's the most direct Mattermark successor for VC-style deal intelligence. Pair it with a contact tool for full coverage.
• You have an enterprise budget and need intent data plus compliance — Choose ZoomInfo if you can justify $30K+, or Cognism if your ICP is European and mobile coverage matters.
• You're targeting European accounts with GDPR requirements — Choose Cognism. No other tool on this list matches its phone-verified mobile coverage and compliance posture for EU outreach.

For most B2B teams moving on from Mattermark, SyncGTM offers the best combination of data depth, coverage breadth, and price. See how B2B data enrichment tools compare in 2026 for a deeper benchmark across more platforms.

Final Verdict: Which Mattermark Alternative Should You Use?

Mattermark's failure taught the market one thing: a company intelligence platform without strong contact enrichment is half a product. Every tool on this list fixes that gap in a different way.

SyncGTMis the best overall Mattermark alternative. It gives you company-level firmographics, verified contacts, and intent signals — everything Mattermark tried to deliver — plus a 50+ provider waterfall that no single-database tool can match on coverage. At $1,069/year versus ZoomInfo's $30K+, it's the practical choice for teams that need enterprise-quality enrichment without an enterprise budget.

Apollo.iowins if you're starting from scratch with no budget and need basic prospecting plus email sequences today.

Crunchbase Pro wins if your core use case is tracking funding rounds and high-growth company signals — the Mattermark use case closest to its original promise.

ZoomInfo wins at enterprise scale if your team has the budget, needs intent data, and requires a widely recognized vendor for procurement approvals.

Cognism wins for EMEA-focused teams that need GDPR compliance and phone-verified mobile numbers as a primary enrichment signal.
