Best Mattermark Alternatives in 2026 (It's Dead)

Mattermark Is Dead - Here Are the Alternatives That Actually Replace It

Mattermark's been gone since 2017. But search for replacements and you'll still find "alternatives" lists stuffed with generic sales tools that don't touch company intelligence. Even Product Hunt's Mattermark alternatives page drifts into marketing automation and CRM add-ons - fine products, wrong job entirely. If you relied on Mattermark for startup data, funding rounds, and growth signals, you need a different shortlist.

Here's the thing: most of what Mattermark did well has been absorbed by a handful of tools that each do one piece better than Mattermark ever did. The trick is knowing which piece you actually need.

Our Picks (TL;DR)

What Happened to Mattermark?

Mattermark raised $17M+ total after its 2012 founding, including a $7.3M Series B in 2016. Then in December 2017, FullContact acquired it for less than $1M. A shareholder letter described under $500K in cash "to facilitate shutdown," plus a stock transaction valued slightly above $500K at the time. Six employees moved over. Most didn't.

After that, the branding got messy. A 2019 blog post claimed Mattermark had "returned as an independent company" with $49/user/month pricing - but it never regained real traction as a startup intelligence product.

FullContact pivoted hard into identity resolution: hashed emails, device IDs, person-level matching. It also moved upmarket, with pricing running roughly ~$99/month on the low end up to ~$2,000+/month for enterprise packages. Useful for certain use cases, but it's not a startup intelligence database by any stretch.

The Hacker News shutdown thread captured the real issue. Users called the dataset "terribly outdated," and even basic contact features didn't work reliably. Meanwhile, Crunchbase, PitchBook, and CB Insights quietly became the default sources for funding and market intel.

Best Replacements for Mattermark

Prospeo - Contact Data

If you used Mattermark as a prospecting shortcut - find a company, grab a decision-maker, push it into outreach - this is the cleanest replacement. Prospeo gives you 300M+ professional profiles, 143M+ verified emails, and 125M+ verified mobile numbers at 98% email accuracy, with data refreshed every 7 days. Most databases still update on a monthly (or longer) cycle, which means you're emailing people who changed jobs six weeks ago.

Pricing is dead simple. A free tier includes 75 verified emails per month, and paid usage works out to about $0.01 per verified email. It plugs into Salesforce and HubSpot natively, and the Chrome extension (40,000+ users) lets you capture verified contact details while you research. We've found it's the fastest way to go from "interesting company" to "email sent" without wrecking your domain reputation with bounced messages - something that was a constant headache with Mattermark's aging data toward the end.

Crunchbase - Company Intelligence

Crunchbase is the closest "Mattermark-shaped" product still standing: company profiles, funding rounds, acquisitions, and leadership changes in one place. In our experience, Crunchbase's free tier covers the majority of what most people actually used Mattermark for - basic research and list-building - without turning your workflow into an enterprise procurement project.

Crunchbase Pro runs roughly ~$49-$99 per user/month and adds advanced search, saved lists, and integrations. If you want a simple, dependable replacement for Mattermark's company pages, this is it. Skip it if you need deep sector taxonomy or investor-grade tracking - that's Tracxn's territory.

Tracxn - Deal Sourcing

Tracxn is what you pick when you're doing real deal sourcing and you care about taxonomy, tracking, and workflow - not just confirming a startup exists. It covers millions of companies and layers on sector mapping, comparables, and monitoring built for VC/PE teams.

Pricing is sales-led, but you can ballpark it: small teams typically land around ~$1,000-$4,000/month depending on seats and modules. Start with the Lite plan to sanity-check coverage and categories before committing. If your fund isn't writing checks above $5M, the cost probably doesn't pencil out - pair Crunchbase with a contact tool instead.

Dealroom.co - Europe Focus

Dealroom.co is the default for European startup ecosystems, and it shows up behind a lot of public innovation reports and accelerator datasets. Premium starts at EUR12,600/year with a 3-seat minimum, and Premium Plus runs about EUR17,000/year with added email credits and CRM connectivity.

Don't mix it up with DealRoom at dealroom.net, which is an M&A virtual data room. Completely different product, confusingly similar name.

Harmonic - AI-Forward Discovery

Harmonic is a strong pick when you want discovery driven by signals like hiring velocity and leadership changes, not just static profiles. It's research-first (not a CRM), designed to surface companies earlier than traditional "funding-round-first" databases.

Pricing isn't public. Assume enterprise spend - roughly ~$10,000-$30,000/year depending on seats and scope - based on where it's positioned in the market.

Owler - Cheap Monitoring

Owler is best for lightweight competitive tracking: follow companies, get alerts, keep a basic profile view. Pro is $39/user/month billed annually. It won't replace Mattermark's depth, but if all you need is a "what's happening with my competitors" dashboard, it works.

Apollo.io - Outreach Included

Apollo bundles a contact database with sequencing and dialing, which makes it a better fit for outbound teams than for research-heavy workflows. Expect ~$49-$99/user/month for paid plans. The data quality on emails is noticeably weaker than dedicated verification tools - the consensus on r/sales is that Apollo's bounce rates run higher than advertised, so watch your sender reputation.

Pricing Comparison

The Real Lesson

Let's be honest: if your deal sizes don't justify a dedicated research team, you don't need an "all-in-one" platform. You need a reliable two-tool stack.

We've watched teams waste weeks trying to recreate Mattermark as a single purchase. Don't. Use Crunchbase for company truth, then add a contact data layer when you're ready to turn research into pipeline. That setup is cheaper, faster, and it doesn't collapse when one vendor changes direction - which, as Mattermark proved, happens more often than anyone expects.

FAQ

Is Mattermark still available?

No. Mattermark sold to FullContact in December 2017 for less than $1M and shut down. FullContact now focuses on identity resolution - a completely different category than startup intelligence or company data.

What's the cheapest Mattermark alternative?

For company research, start with Crunchbase's free tier. For verified contact data, Prospeo's free plan gives you 75 verified emails per month at 98% accuracy, so you can run a basic "research + outreach" workflow for $0.

What's the best free option for startup data?

Crunchbase's free tier is the strongest starting point for company profiles and funding history. For investor-style categorization and tracking without paying upfront, Tracxn's Lite plan offers a limited but useful taste of deal-sourcing workflows.

Are there good Reddit threads on Mattermark replacements?

Not many recent ones. Most Reddit discussions jump straight to big-name databases like Crunchbase, PitchBook, and CB Insights. A lot of community "alternatives" lists drift into unrelated sales tools - useful products, but not true Mattermark replacements for company intelligence. The r/startups and r/venturecapital subs occasionally surface newer tools like Harmonic, but threads are sparse.
