LimeLeads vs NinjaPear: Honest Comparison (2026)

LimeLeads vs NinjaPear: A Comparison That Shouldn't Exist

LimeLeads vs NinjaPear is one of those matchups that falls apart the moment you look under the hood. LimeLeads is a US-only contact database. NinjaPear is a company intelligence API for developers. Comparing them is like comparing a CRM to a spreadsheet - they solve fundamentally different problems.

We evaluated both platforms side by side, and they genuinely don't overlap.

30-Second Verdict

LimeLeads gives you US business contacts to export and email. NinjaPear gives developers API endpoints for customer mapping, competitive intelligence, and company enrichment. They don't compete.

What Is LimeLeads?

LimeLeads is a B2B contact database focused on US-based businesses. You search by filters, unlock contacts with credits, and export to CSV or Excel. Pricing is straightforward: Pro runs $99/month for 500 credits, Business is $150/month for 1,500 credits, and Enterprise hits $400/month for 5,000 credits. They also advertise a yearly option at 35% off.

It holds a 4.0/5 on G2, though the reviews aren't all rosy. One quoted G2 reviewer in Woodpecker's LimeLeads write-up called it "more costly than other tools" and flagged email accuracy as needing improvement.

Here's the thing that's hard to ignore: in 2020, 49 million LimeLeads records - names, titles, emails, phone numbers, company details - were put up for sale after a researcher found an unsecured Elasticsearch server indexed on Shodan since at least July 2019. LimeLeads didn't respond to ZDNet's request for comment. For a company whose entire job is storing business contact data, that's a serious trust problem, and it's the kind of thing that should factor into any purchasing decision.

What Is NinjaPear?

NinjaPear is the successor to Proxycurl, built by the same team at Nubela. Proxycurl grew to roughly $10M in revenue before a lawsuit forced a shutdown in early 2025, and NinjaPear pivoted to company intelligence - Customers, Companies, Competitors, and Employees modules delivered via API.

This is a developer tool. You hit endpoints to map business relationships like customers, investors, and partners, pull competitor overlaps, or enrich company profiles. It's not a place where a sales rep searches for prospects and exports a list.

Pricing reflects the API-first model. All plans require a 12-month commitment, with tiers ranging from about $49 to $1,899/month. Credits are usage-based, and the math gets granular fast - a Customer Listing request costs 1 credit per request plus 2 credits per customer returned. A few things worth knowing:

• Subscription credits expire at the end of each billing cycle
• Starting a subscription kills any remaining pay-as-you-go credits
• The free trial is 3 days with 10 credits

NinjaPear doesn't appear on G2 or Capterra yet, so third-party validation is thin.

Side-by-Side Comparison

Which One Do You Actually Need?

Let's be honest - most people landing on a "LimeLeads vs NinjaPear" comparison want contact data for outbound. Two clear paths:

Path 1: You need prospect lists to email today. You're in the contact database category. NinjaPear isn't built for this. It's an API for company intelligence, not a sales list tool.

Path 2: You're a developer building competitive intelligence or customer mapping features into a product. NinjaPear is the right category, and the only option here that serves that use case.

LimeLeads fits Path 1, but with real limitations. US-only coverage cuts out every international market. The 2020 breach raises questions about data stewardship. And the recurring theme in third-party write-ups is that accuracy and cost are pain points - not what you want from a tool whose entire job is delivering valid contacts.

A Better Option for Contact Data

Most teams searching for contact databases in 2026 don't need a US-only tool with a breach on its record. They need global, verified data at a price that doesn't punish scale.

If you're comparing vendors, it also helps to understand what modern data enrichment looks like (and what it doesn't).

Prospeo's leads database covers 300M+ professional profiles globally with 98% email accuracy, 143M+ verified emails, and 125M+ verified mobile numbers. Data refreshes every 7 days - not the 6-week industry average. You get 30+ search filters including buyer intent, technographics, job changes, and headcount growth.

The cost difference is stark. On LimeLeads, $150/month gets you 1,500 credits, and one credit equals one verified contact unlocked for export - so you're capped at 1,500 US-only contacts on that tier. With Prospeo's roughly $0.01 per email unit economics, $150 gets you about 15,000 verified emails with global coverage. That's a 10x difference before you even factor in the international reach.

The free tier includes 75 emails and 100 Chrome extension credits per month - enough to test before committing a dollar. No contracts, cancel whenever you want.

We've seen teams switch from US-only databases and immediately unlock pipeline in EMEA and APAC markets they couldn't touch before. If your outbound isn't limited to the US - and in 2026, whose is? - the coverage gap alone makes the decision.

If you're building a repeatable outbound motion, pair better data with better sales prospecting techniques and a clean lead generation workflow.

FAQ

Is NinjaPear the same as Proxycurl?

Same team, different product. NinjaPear is built by Nubela, the company behind Proxycurl. After a lawsuit forced Proxycurl to shut down in early 2025, the team pivoted to NinjaPear, focusing on company intelligence APIs rather than profile scraping.

Does LimeLeads work outside the US?

No. LimeLeads is limited to US-based business contacts only. If you're prospecting internationally, you need a provider with global coverage.

What's the best free alternative to both?

Prospeo's free tier gives you 75 verified emails and 100 Chrome extension credits per month with no credit card required. That's far more usable than NinjaPear's 3-day, 10-credit trial, and LimeLeads doesn't advertise a free option at all.
