DiscoverOrg vs Mattermark: Neither Tool Exists Like It Used To
DiscoverOrg got acquired and folded into ZoomInfo in 2019. Mattermark shut down that same year after selling to FullContact for less than $1M. If you're still comparing these two, you're reading recycled content from 2017.
Here's what actually happened to each platform, and what to use instead.
30-Second Verdict
What Happened to Each Platform
DiscoverOrg Became ZoomInfo
On February 4, 2019, DiscoverOrg acquired ZoomInfo. By September 2019, the combined brand was marketed as "ZoomInfo Powered by DiscoverOrg." Over time, the DiscoverOrg name disappeared entirely, and ZoomInfo became the primary brand serving 13,500+ clients with a database covering 113M business emails and 59M direct dials.
If you're looking for DiscoverOrg, you're buying ZoomInfo. Full stop.
Mattermark's Shutdown
Mattermark's story is grimmer. After raising $17M+ since 2012, the company shut down in December 2017. TechCrunch obtained liquidation documents showing FullContact paid less than $1M - cash plus stock - just a year after Mattermark had closed a $7.3M Series B. The Mattermark website now positions the product as relaunched with "millions" of private companies, but there's no public relaunch date, no ownership clarity, and no independent reviews we could find. We wouldn't commit budget to that.
Both DiscoverOrg and Mattermark failed to survive - but the need for accurate B2B data didn't go away. Prospeo covers 300M+ profiles with 98% email accuracy, 125M+ verified mobiles, and a 7-day refresh cycle. All at $0.01/email with no annual contract.

Pricing Reality
ZoomInfo's list price starts around $14,995/year for Professional, but most teams pay $30,000-$60,000 once you add seats, credits, and modules. Negotiated discounts of 30-65% are common, but you'll need multi-year commitments to get them. Contracts are annual-only, renewals bump 10-20%, and data-destroy clauses force you to delete ZoomInfo-sourced contacts if you cancel. The consensus on r/sales is that contract lock-in and renewal surprises are the breaking point for most teams.
Mattermark's Salesforce enrichment runs $49/user/month billed annually. Reasonable on paper, but you're paying for a dataset nobody has independently validated.
Let's be honest: if your average deal size sits below five figures, ZoomInfo-level spend makes no mathematical sense. You'll burn half your deal value on data before a single call is made.
What to Use Instead in 2026
Prospeo
The need behind both DiscoverOrg and Mattermark was always the same: find the right people at the right companies with data you can trust. Prospeo's B2B database covers 300M+ profiles with 143M+ verified emails and 125M+ verified mobile numbers, all refreshed every 7 days versus the 6-week industry average. Email accuracy hits 98%, and mobile pickup rates reach 30% across regions.
We've tested this against ZoomInfo and Apollo side by side, and the bounce rate difference is stark - teams using Prospeo consistently see sub-4% bounce rates where ZoomInfo-sourced lists were running 35%+. One customer, Snyk, cut their bounce rate from 35-40% to under 5% and saw AE-sourced pipeline jump 180%.
Search with 30+ filters including buyer intent, technographics, and job changes, then export verified contacts into Salesforce, HubSpot, or your sequencer of choice. No annual commitment, no sales call required.
Apollo
Apollo works best as an all-in-one outbound platform when you want prospecting and sequencing in a single tool. The free tier is generous. Skip it if email accuracy is your top priority - bounce rates run higher than dedicated verification tools, and in our experience the mobile data is thin outside the US. Paid plans run $49-$99/user/month.
UpLead
UpLead includes email verification on exports, so you don't need a separate cleaning step. Starts at $99/month. A strong pick for mid-market teams who want clean data without complexity, but limited if you need mobile numbers at scale.
Snyk replaced their legacy data provider and cut bounce rates from 35-40% to under 5% - while growing AE-sourced pipeline 180%. Prospeo's 5-step verification and weekly refresh mean you're never emailing dead contacts.
Replace extinct tools with data that actually connects you to buyers.
FAQ
Is DiscoverOrg still available?
No. DiscoverOrg was absorbed into ZoomInfo after the 2019 acquisition and isn't sold as a standalone product. Expect to pay $15,000/year minimum, with most teams landing in the $30K-$60K range after add-ons.
Did Mattermark relaunch?
The Mattermark website shows signs of a relaunch with "millions" of private company profiles, but there's no confirmed relaunch date or independent review coverage as of 2026. Prospeo and Apollo are safer bets for teams that need validated data today.
