Mattermark vs ZoomInfo: One Is Dead, Here's What to Use Instead
Mattermark was acquired for less than $1M in late 2017, and the cash was literally used to wind down the company. This isn't a real comparison anymore.
What Happened to Mattermark?
Mattermark raised $21.2M in disclosed venture funding, built a company intelligence product focused on growth signals and funding data, then ran straight into a wall. Crunchbase, PitchBook, and CB Insights ate its market. In December 2017, TechCrunch reported the company was shutting down after selling to FullContact for under $1M. Common stockholders received nothing.
At its peak, Mattermark's Growth & Mindshare Score and funding data helped teams like Looker cut per-company research from five minutes to thirty seconds. FullContact announced the acquisition in January 2018, absorbing Mattermark's 4 million company profiles and 20 million contacts into its identity graph.
Today, Mattermark's website displays a banner claiming it has "re-launched as an independent company." But there's little modern third-party validation: Serchen shows zero reviews, no meaningful G2 footprint surfaced in our research, and third-party directories list conflicting pricing - $49/user on one site, $500/user/month on another. Treat it as defunct.
What ZoomInfo Offers in 2026
Use ZoomInfo if you're a mid-market or enterprise team that needs a full GTM platform - database, intent data, workflow automation, and org charts under one roof. ZoomInfo's database covers 500M+ professional profiles. It holds a 4.5/5 on G2 from over 9,000 reviews, which is genuinely impressive at that volume.
Skip ZoomInfo if you're a small team, a startup, or an agency that just needs accurate contact data without the platform overhead. Typical annual contracts look like this: $15,000-$18,000 for Professional, $22,000-$28,000 for Advanced, and $35,000-$45,000+ for Elite. There's a free Lite tier with 10 credits/month (25 with Community Edition), but it's more teaser than tool.
Here's the thing: ZoomInfo is still the best all-in-one GTM platform. But most teams don't need all-in-one. They need accurate emails and direct dials that actually connect. Paying $15K+ for a platform you use at 20% capacity is how sales budgets die quietly.
One platform in this comparison is defunct. The other charges $15K+ and delivers 87% email accuracy with a 12.5% mobile pickup rate. Prospeo gives you 98% verified emails, 30% mobile pickup, and a 7-day data refresh - at roughly $0.01 per lead. No annual contract. No sales call.
Stop overpaying for outdated data from legacy platforms.
What ZoomInfo Users Actually Say
The #1 complaint on r/sales is price relative to value. One user described paying $15-20K and finding that the "majority of phone numbers do not go to the people specified" - routing to front desks instead of direct lines. The same thread flagged a buggy Chrome extension that crashed a 32GB MacBook.
G2 reviews echo a similar pattern. Users love the search experience and CRM integrations, but recurring cons include outdated data and inaccurate contacts. Even a 2015 Reddit thread called 10 credits for ~$30 "a bit steep." A decade later, that perception hasn't changed.

What to Use Instead
Real results back this up: Snyk's 50-person AE team cut bounce rates from 35% to under 5% and grew AE-sourced pipeline 180% after switching. Self-serve, no contracts, roughly $0.01 per lead.
For teams that want an all-in-one prospecting platform with a generous free tier, Apollo.io ($49-99/mo per user) is worth testing. And if you're selling heavily into EMEA, Cognism (~$1,000-3,000/mo) deserves a look for its European mobile coverage.
Snyk's 50 AEs cut bounce rates from 35% to under 5% and grew pipeline 180% after switching to Prospeo. 300M+ profiles, 125M+ verified mobiles, and weekly data refreshes - all self-serve with 75 free emails per month to start.
See why 15,000+ companies left five-figure contracts behind.
FAQ
Is Mattermark still available in 2026?
Effectively, no. The product was acquired for under $1M in 2017, has zero modern reviews, and shows wildly conflicting pricing across directories. Don't build a workflow around it.
How much does ZoomInfo cost?
Typical annual contracts run $15,000-$45,000+ depending on seats and tier. There's a free Lite tier with 10 monthly credits (25 with Community Edition). Expect 10-20% renewal increases annually.
What's a good free alternative to both?
Prospeo offers 75 free emails per month plus 100 Chrome extension credits - no credit card or sales call required. For teams that need verified contact data without committing to five-figure annual contracts, it's the strongest free starting point alongside Apollo.io's freemium plan.
Is Mattermark vs ZoomInfo still a valid comparison?
No. Mattermark is defunct. If you need ZoomInfo-level data at a fraction of the cost, look at self-serve platforms with verified contact databases, weekly data refresh cycles, and no annual lock-in.
