LeadsForge vs Mattermark: Honest Comparison (2026)
If you're weighing LeadsForge against Mattermark, there's a decent chance you need neither. One is a company intelligence platform built around firmographics and growth signals. The other is a contact search tool with accuracy questions hanging over it. The real question isn't which is better - it's whether either one actually solves your problem.
30-Second Verdict
Mattermark is for analysts and VC teams who want company-level growth signals, funding data, and firmographics. It's not built as an outbound contact-finding tool.
LeadsForge is for outbound reps who want a chat-based interface to pull contact lists fast. It delivers emails and phones, but G2 reviewers flag data inconsistency, and Trustpilot users mention cancellation friction.
What Is Mattermark?
Mattermark sold to FullContact in late 2017 for under $1M total - a mix of under $500K cash and a stock transaction valued slightly above $500K. It later re-launched as an independent company and brought back much of its early staff, including founders Danielle and Kevin Morrill.
Today it covers 4M+ companies with 80+ data fields. The API supports REST and GraphQL and returns fields like employee count trends, revenue ranges, funding events, and Mattermark Score, which is useful for account prioritization. There's also a Salesforce Data Enrichment add-on, and its iOS "Company Data and News" app is free.
Here's the thing: Mattermark is company intelligence, full stop. If you're building outbound lists, you'll still need a dedicated contact data platform for verified emails and phone numbers.
What Is LeadsForge?
LeadsForge uses a chat-based interface where you describe your ICP in natural language and it pulls matching contacts with emails, phone numbers, and profile URLs. It runs waterfall data enrichment across multiple sources with instant verification.
The reviews tell a mixed story. G2 gives it 4.5/5 across 12 reviews - users praise speed and filtering but flag a steep learning curve and inconsistent data quality. Trustpilot sits at 4.0/5 from 11 reviews, with users loving the time savings but at least one reviewer calling it "very hard to cancel." That's a red flag we don't love seeing.
In our experience, the credit math catches teams off guard. One email costs 1 credit, but a single phone number costs 10. That 2,000-credit plan gets you 2,000 emails or just 200 phone numbers. Not both.
LeadsForge charges 10 credits per phone number. Prospeo gives you 125M+ verified mobiles with a 30% pickup rate - plus 143M+ emails at 98% accuracy. No credit-math surprises, no cancellation friction, and data refreshes every 7 days.
Replace two tools with one platform that actually verifies its data.

These aren't competitors. Mattermark gives you company data for research and prioritization. LeadsForge gives you contact data with accuracy concerns flagged across review sites. Neither tool generates much Reddit chatter either - Mattermark's post-acquisition confusion and LeadsForge's small review base mean you're largely on your own for peer validation.

Let's be honest: if your average deal size sits below $15k, you don't need Mattermark's company intelligence layer. A good contact data tool with firmographic filters does the job at a third of the cost.
Who Should Use Which?
Use Mattermark if you're a VC team, market analyst, or account strategist who needs company growth signals and funding data - and you already have a separate tool for contact data.
Use LeadsForge if you're an outbound rep who wants AI-assisted list building and can tolerate a learning curve. Verify the data independently before you sequence it.
Skip both if your core need is verified emails and direct dials with high confidence. We've tested both workflows, and stitching a company intelligence tool to a separate contact finder creates more friction than it solves. Prospeo's B2B database combines company-level filtering - buyer intent, technographics, headcount growth - with verified contact data in one platform. Data refreshes every 7 days instead of the 6-week industry average, so you're not sequencing stale contacts. With 300M+ professional profiles and 30+ search filters, it covers the firmographic intelligence Mattermark provides alongside the contact enrichment LeadsForge attempts, without the credit-math surprises or cancellation headaches.
Mattermark covers company signals. LeadsForge covers contacts (sometimes). Prospeo covers both - 30+ filters including buyer intent, technographics, and headcount growth layered on top of 300M+ verified profiles. No stitching required.

FAQ
Is Mattermark Still Active in 2026?
Yes. Mattermark re-launched independently after the FullContact acquisition and operates with published pricing, a 14-day free trial, and active API access. Some documentation still references legacy fields like Alexa rank, which raises freshness questions in certain data categories.
Does LeadsForge Verify Emails?
LeadsForge supports email validation, but verification costs additional credits - and G2 reviewers flag occasional inaccuracy in exported contacts. For teams where deliverability isn't negotiable, pairing with a dedicated verification tool that runs a multi-step process eliminates bounce-rate risk.
Can I Replace Both Tools With One Platform?
Yes. If you need company intelligence and verified contact data, a unified platform removes the integration tax. Prospeo covers 30+ firmographic and intent filters alongside 143M+ verified emails and 125M+ verified mobiles, combining what Mattermark and LeadsForge do separately at roughly $0.01 per email with no annual lock-in.
