ListKit vs Mattermark: A Comparison That Doesn't Work the Way You Think
If you're searching for ListKit vs Mattermark, someone pointed you in the wrong direction. ListKit is a contact database built for cold outbound. Mattermark is a company intelligence platform built for VC research and corp dev. Comparing them is like comparing a fishing rod to a weather station - same ocean, completely different purposes.
Let's sort this out anyway, because we've seen this question pop up enough times that it deserves a clear answer.
30-Second Verdict
- You need contacts for outbound - ListKit. It's a contact database with 731M triple-verified email contacts, intent data, and CRM integrations.
- You need company intelligence for VC or corp dev - Mattermark, with real caveats about vendor stability.
What Mattermark Actually Is in 2026
Mattermark's story is one of the stranger ones in B2B data. The company raised $17M+ in total funding, then sold to FullContact in 2017 for under $1M - less than $500K in cash plus stock. That's not an acqui-hire. That's a fire sale.
It has since re-launched as an independent company under co-founders Danielle Morrill and Kevin Morrill, plus former product lead Paul Denya. The core product covers 4M+ companies with 80+ data points: funding rounds, growth signals, news, VC portfolio data. It's company intelligence, not a contact database.
Here's the thing: Mattermark does have a "Contact Information Beta," but contact data isn't the core product. The pricing creates a real barrier - the $49/user/month Standard plan is in-browser only with no CSV exports. Want to pull data out? That's the Professional plan at $500/user/month on an annual contract. A separate self-service pricing announcement also listed a $200/month Individual plan that doesn't match the current pricing page lineup, which doesn't inspire confidence.
Use this if you're in VC, PE, or corp dev and need private company intelligence with funding data.
Skip this if you need verified emails or phone numbers for outbound. Mattermark's G2 profile shows zero reviews and has been inactive for over a year. That's a vendor risk signal you can't ignore.
What ListKit Actually Is
ListKit is a straightforward contact database for outbound teams. The database covers 731M triple-verified email contacts, and the platform layers on AI company search, intent data from 21B daily buying signals, and CRM integrations.
Pricing runs on credits. The Free plan gives you 100 credits. Professional costs $83/month billed yearly for 24,000 credits, Scale runs $253/month for 120,000 credits, and Ultimate hits $508/month for 600,000 credits. Their pricing page also shows a calculator-style recommendation for "Pro" at $97/month for 2,000 credits, which is why you'll sometimes see both numbers floating around. One credit gets you a business email; mobile numbers cost five credits.
Every plan includes unlimited users - a rarity in this category where most competitors charge per seat.
On G2, ListKit sits at 4.7/5 across 388 reviews. Review summaries flag occasional outdated data and some setup friction, which is normal at this database scale. In our experience testing contact databases, no provider is immune to stale records; the question is always how fast they refresh.
ListKit gives you contacts. Mattermark gives you company intel. Prospeo gives you both - 300M+ profiles with 30+ filters, 98% email accuracy, and a 7-day refresh cycle that keeps your lists clean. No $500 export fees. No beta-stage contact data.
Start with 75 free verified emails - no contract, no sales call.
Side-by-Side Comparison
| Feature | Mattermark | ListKit |
|---|---|---|
| Category | Company intel | Contact database |
| Database size | 4M+ companies | 731M email contacts |
| Verified contacts | Contact Information Beta | Triple-verified emails |
| CSV export | $500/user/mo (annual) | Included |
| Entry pricing | $49/user/mo | Free ($0) |
| G2 rating | 0 reviews | 4.7/5 (388) |
| Intent data | Not a core feature | Yes (21B daily signals) |
| Free tier | No free web plan | Yes (100 credits) |
| API access | $99-$999/mo (annual) | Not public |
Three contrasts jump off this table. Mattermark charges $500/user/month just to get CSV export - ListKit is built for outbound list-building from the ground up. Then there's 388 G2 reviews versus zero. And beta contact data versus a database designed around verified outbound contacts. The gap isn't close.
The consensus on r/sales and similar communities is that email sender tools are increasingly bundling lead data into their core product. ListKit fits that trend. Mattermark doesn't.
The Verdict on ListKit vs Mattermark
For cold outbound and SDR teams, ListKit wins and Mattermark isn't even in the conversation. ListKit is a contact database with verified emails, phone numbers, and intent signals. Mattermark is a company research tool with beta contact features.
For VC research and corp dev, Mattermark or Crunchbase are the right category - but the zero-review G2 profile and shutdown history are real vendor risks to weigh before signing an annual contract. We'd want to see active product updates and community engagement before committing budget there.
Look, this comparison shouldn't exist. They solve different problems entirely. If someone recommended Mattermark for your outbound stack, they're thinking of the pre-acquisition era that raised $17M+ and had buzz. That company doesn't exist anymore.
A Verified Contact Alternative Worth Knowing
If you landed here looking for verified emails and realized Mattermark doesn't do that, Prospeo covers 143M+ verified emails and 125M+ verified mobile numbers at 98% accuracy on a 7-day refresh cycle - compared to the 6-week industry average. There's a free tier with 75 emails/month, no contracts, and paid plans run roughly $0.01 per email. The proprietary email-finding infrastructure and 5-step verification process mean fewer bounces and cleaner lists out of the box. Pair it with ListKit for company search, or use Prospeo's own firmographic filters to build lists directly - either way, you're not paying $500/month for the privilege of exporting a CSV.
Zero G2 reviews and beta contact features aren't risks your outbound pipeline can afford. Prospeo delivers 143M+ verified emails and 125M+ mobile numbers through proprietary 5-step verification - trusted by 15,000+ companies with a 98% accuracy rate.
Stop gambling on unproven tools when verified data costs $0.01 per email.
FAQ
Is Mattermark still active in 2026?
Yes, it re-launched as an independent company under its original co-founders. That said, its G2 profile has zero reviews and has been inactive for over a year, which raises real questions about active development, support, and long-term viability. If you're evaluating it, ask for a recent product changelog before signing anything.
Can Mattermark replace ListKit for cold outreach?
No. Mattermark is a company intelligence platform with beta-stage contact data covering 4M+ companies. ListKit is a contact database with 731M triple-verified email contacts built specifically for outbound. They serve fundamentally different use cases, and trying to force Mattermark into an outbound workflow will frustrate your team.
What's the cheapest way to get verified B2B emails?
Prospeo's free tier gives you 75 verified emails per month at no cost, with paid plans at roughly $0.01 per email and no annual contracts. ListKit's free tier offers 100 credits. Both are dramatically cheaper than Mattermark's $500/user/month Professional tier requirement for CSV export.
