BookYourData vs Mattermark: Different Tools for Different Jobs
This comparison shouldn't exist. One gives you contacts to call. The other tells you which companies are growing. They don't compete - they solve fundamentally different problems, and lumping them together leads to bad buying decisions.
30-Second Verdict
BookYourData - Pick it if you need verified B2B emails and direct dials for outbound campaigns. Pay-as-you-go, 97% accuracy guarantee, no subscription.
Mattermark - Pick it if you need company intelligence: growth scores, funding rounds, investor portfolios. It's not a contact list tool.
What Each Tool Actually Does
BookYourData
BookYourData is a pay-per-credit contact marketplace. You search by job title, industry, company size, or technographics, and you get verified emails and direct dials. The database covers 250M+ contacts across 200+ countries. Credits never expire, there's no subscription lock-in, and they offer a 97% accuracy guarantee with refunds for bounced contacts. Think of it as a vending machine for B2B contact data.
Mattermark
Mattermark is a company intelligence platform - closer to Crunchbase than to ZoomInfo. It tracks over 4 million companies with 80+ data fields, including growth and mindshare scores, funding and VC portfolio data, revenue ranges, and employee counts. It does include contact search by job title or name, but there's no email accuracy guarantee or bounce-refund policy like you'd find with contact-first databases. The platform also offers REST and GraphQL APIs for developers and a free iOS app that doesn't even require an account.
Mattermark's Backstory
Mattermark has had a wild ride. In December 2017, TechCrunch reported the company was shutting down after selling to FullContact for less than $1M - with under $500k in cash used to wind things down. For years, it was effectively dead.
Then it came back. Mattermark relaunched as an independent company with founders Danielle and Kevin Morrill returning alongside former team members. The product is live and purchasable today, but its G2 profile is inactive with zero reviews. That's a red flag worth noting before you hand over a credit card.
Choosing between a contact database and a company intelligence tool means paying twice and stitching data together yourself. Prospeo combines 300M+ verified profiles with 30+ filters - intent data, technographics, funding, headcount growth - all refreshed every 7 days. At $0.01/email, one month of Mattermark Professional buys you 50,000 verified contacts.
Stop paying for two tools when one does both better.
Feature-by-Feature Comparison
| Category | BookYourData | Mattermark | Winner |
|---|---|---|---|
| Data type | Verified contacts | Company intelligence | Depends on need |
| Database size | 250M+ contacts | 4M companies | BookYourData (volume) |
| Accuracy guarantee | 97% with refund | None | BookYourData |
| G2 rating | 4.9/5 (394 reviews) | 0 reviews (inactive) | BookYourData |
| Pricing model | Pay-per-credit | Monthly subscription | BookYourData (flexibility) |
| CSV export | Every plan | Professional plan ($500/user/mo) | BookYourData |
| API access | Available | $99-$999/year (REST + GraphQL) | Mattermark (transparency) |
The mismatch is obvious. BookYourData is built for reps who need a list to call tomorrow. Mattermark is built for analysts researching which companies to target next quarter.
If you're running outbound sequences, Mattermark won't give you what you need.
Pricing Breakdown
| Plan | BookYourData | Mattermark |
|---|---|---|
| Entry tier | $99 for 250 credits | $49/user/mo (Standard) |
| Mid tier | Volume discounts | $500/user/mo (Professional) |
| Salesforce enrichment | N/A | $49/seat/mo (annual) |
| Enterprise | Contact sales | Custom pricing |
| API | Available | $99-$999/year |
| Free trial | 10 free credits | 14-day trial |
Here's the thing about Mattermark's pricing: CSV export is gated behind the $500/user/mo Professional plan. You can browse company data on the Standard tier, but you can't export it to a spreadsheet without paying ten times more. We've tested pay-per-credit models against subscriptions across dozens of client engagements, and for outbound teams that just need exportable contact lists, the subscription model with export paywalls is almost always a worse deal.
BookYourData includes exports in every plan. You're buying data to use, not data to look at.
If your outbound motion is email-first and your average deal size sits below $25k, you probably don't need company intelligence at all. You need accurate emails and a good sequence. Mattermark is a research tool for investment analysts and corporate development teams, not for SDRs booking meetings.
Data Quality and Reviews
BookYourData carries a 4.9/5 on G2 with 394 reviews - unusually high for a data tool. On Trustpilot, the picture is more mixed at 3.8/5, with complaints about stale data and pricing surprises.
A Reddit user comparing BookYourData to ZoomInfo and Apollo reported a 2.3% bounce rate on their first batch, compared to 7-8% from ZoomInfo and 6-7% from Apollo. One data point, but a telling one.
Mattermark has zero third-party reviews on G2. We've seen teams adopt tools with thin review footprints before, and it almost always means you're flying blind on support quality, data freshness, and reliability. Let's be honest - that's a tough sell when you're betting your pipeline on the data.
The Third Option Worth Considering
If you need both verified contacts and company-level intelligence, you don't need two subscriptions. Prospeo covers 300M+ professional profiles with 98% email accuracy and layers in company-level filters - intent data tracking 15,000 topics, technographics, funding signals, headcount growth, and 30+ search filters. Data refreshes every 7 days, not every 6 weeks. For the cost of one month of Mattermark Professional, you could verify 50,000 emails through Prospeo and get access to 125M+ verified mobile numbers with a 30% pickup rate on top.
BookYourData guarantees 97% accuracy. Mattermark guarantees nothing. Prospeo delivers 98% verified email accuracy across 143M+ emails, plus 125M+ mobile numbers with a 30% pickup rate - backed by a 5-step verification process and 7-day data refresh cycle. No subscriptions, no contracts, no export paywalls.
Get the highest accuracy in B2B data without the subscription trap.
FAQ
Is Mattermark still active in 2026?
Yes. It relaunched as an independent company after the 2017 FullContact acquisition, with original founders returning. The product is purchasable today, though its G2 profile remains inactive with zero reviews - so due diligence is limited.
Can I get verified emails from Mattermark?
Not reliably. Mattermark includes contact search, but there's no email accuracy guarantee or bounce refund policy. BookYourData offers a 97% accuracy guarantee, and Prospeo delivers 98% verified accuracy across 143M+ emails - both are purpose-built for deliverable contact data.
Which tool is better for outbound sales?
BookYourData. It provides verified B2B contacts with a 97% accuracy guarantee designed for cold outreach. Mattermark is a company research tool for analysts and investors, not a contact database for sales teams running sequences.
