Mattermark vs SalesIntel: Which B2B Data Tool Is Worth It in 2026?
These two tools barely overlap. One focuses on company intelligence and growth signals, the other is built around a contact database. We pulled together vendor pricing pages, G2 reviews, and Vendr contract benchmarks to build this comparison from scratch, because no direct head-to-head existed anywhere we looked.
30-Second Verdict
Pick Mattermark if you need company-level growth signals on a budget ($49/mo) and can live with a 4M+ company database that doesn't prioritize contact data.

Pick SalesIntel if you need a large human-verified contact database with intent data and you're comfortable with an annual contract that typically lands in the $15K-$25K/year range for small-to-mid teams.
Skip both if you need verified emails and direct dials with a self-serve buying experience, no annual lock-in, and faster data refresh. There are better options.
Is Mattermark Still Around?
Here's the thing: Mattermark sold to FullContact for less than $1M in late 2017 and effectively shut down. At some point, the brand relaunched. Their pricing page now carries a banner reading "Mattermark has re-launched as an independent company!" with active subscription plans.
The database covers 4M+ companies with 80+ data points each - decent for company intelligence, but tiny compared to modern contact databases. The review footprint is thin, which makes current data quality hard to gauge. If you're betting on Mattermark, you're betting on a comeback story with limited social proof.
SalesIntel at a Glance
SalesIntel plays in a different league size-wise. The database includes 200M+ B2B contacts, 54M+ verified mobile numbers, and 40M+ companies, all maintained by 2,000+ human researchers on a 90-day refresh cycle. The platform claims up to 95% accuracy and includes Bombora-powered intent with 60K+ intent signals.

On G2, SalesIntel holds a 4.3/5 from 538 reviews. Users praise ease of use and CRM integrations, but "Outdated Data" and "Inaccurate Data" each show up in 40+ reviews. For a platform that leads with human verification, that's a real gap between promise and experience. A Reddit thread in r/sales shows a user trialing SalesIntel as a ZoomInfo alternative, specifically questioning mobile accuracy - but community responses were sparse.

Mattermark gives you 4M companies with no contact data. SalesIntel gives you contacts on a 90-day refresh with 40+ G2 reviews flagging outdated records. Prospeo gives you 300M+ profiles, 143M+ verified emails at 98% accuracy, and 125M+ mobile numbers - refreshed every 7 days, not every 90.

Side-by-Side Comparison
Let's be honest: this comparison barely makes sense. Mattermark is company intelligence. SalesIntel is a contact database. But if you're evaluating both, this table clarifies where they diverge.

| Dimension | Mattermark | SalesIntel | Winner |
|---|---|---|---|
| Database size | 4M+ companies | 40M+ companies, 200M+ contacts | SalesIntel |
| Verified emails | Not primary focus | Included (debated quality) | SalesIntel |
| Verified mobiles | Not available | 54M+ | SalesIntel |
| Data refresh | Unclear | 90 days | SalesIntel |
| Intent data | No | Yes (Bombora) | SalesIntel |
| Starting price | $49/user/mo | ~$10,000/yr | Mattermark |
| Contracts | Month-to-month (Standard) | Annual only | Mattermark |
| CRM integrations | Salesforce (enrichment add-on) | Salesforce, HubSpot | SalesIntel |
If you need contact-level data - emails, mobiles, intent signals - Mattermark isn't built for that. If you need company growth signals and funding-style intelligence, SalesIntel is overkill.
Pricing Breakdown
Mattermark is straightforward:

| Plan | Price |
|---|---|
| Standard | $49/user/mo (monthly) |
| Professional | $500/user/mo (annual) |
| Enterprise | Custom |
| Salesforce Enrichment | $49/seat/mo (annual) |
| API | $99-$999/mo (annual) |
Transparent pricing. Refreshing for B2B data.
SalesIntel is quote-only with no public price list, which makes budgeting harder than it needs to be. Vendr benchmark data across 20 contracts puts the median annual cost at $17,599/year, ranging from $8,670 to $41,380. A commonly referenced starting point is roughly $10,000/year for a Business plan with 30,000 download credits, with platform users often priced at $1,200/user/year and overage credits running $0.33 each. Other contract analyses show credit-based tiers ranging from $99/month (Individual, 100 credits) up to $48,000/year (Enterprise, 100K credits).
Add intent data ($5K-$10K/year) and VisitorIntel ($1K-$3K/year), and a $15K budget can easily become $25K+. Exports are also capped at 500 contacts per pull, which slows high-volume workflows.
Look - if you're comparing either tool to ZoomInfo or Apollo, that's a different conversation entirely. Both Mattermark and SalesIntel are niche picks. Most mid-market teams don't need Mattermark's company signals or SalesIntel's five-figure contracts. They need accurate contact data at a reasonable price.
The Verdict
Use Mattermark if you're a VC analyst or growth researcher who needs company-level signals - funding rounds, growth scores, headcount trends - and $49/mo fits your workflow. The database is small and the product's trajectory is uncertain.
Use SalesIntel if you're a mid-market sales team that needs human-verified contacts plus intent data and you're comfortable with annual contracts in the $15K-$25K range. The data is solid when fresh, but 40+ G2 reviewers flagging outdated records means you'll want to verify before sequencing.
Skip both if you need a modern, self-serve data platform that prioritizes accuracy and freshness over legacy packaging. When weighing Mattermark vs SalesIntel, most outbound teams realize neither tool is quite right - the real question is what replaces them.
If Neither Fits

We've tested both workflows side by side, and the difference in data freshness is immediately obvious when you're running outbound sequences at scale. Prospeo's database covers 300M+ professional profiles with 143M+ verified emails at 98% accuracy and 125M+ verified mobile numbers with a 30% pickup rate. You get buyer intent powered by Bombora across 15,000 topics, technographics, job changes, and headcount growth signals - all filterable through 30+ search criteria. Native integrations cover Salesforce, HubSpot, Lemlist, Instantly, and Clay.
If your primary need is verified emails and direct dials for outbound, neither Mattermark nor SalesIntel is the right starting point.

SalesIntel's median contract is $17,599/year with capped exports and extra fees for intent data. Prospeo includes Bombora intent across 15,000 topics, 30+ search filters, and native CRM integrations - all self-serve with no sales calls and no annual lock-in.
Skip the five-figure contract and start prospecting in minutes.
