Muraena Review: B2B Lead Database with 140M Profiles

What Is Muraena?

Muraena is a B2B lead generation tool currently available as a lifetime deal on AppSumo. At its core, it's a massive database of over 140 million business profiles that you can search through using both traditional filters and an AI-powered natural language search.

The AI component is designed to make finding leads more intuitive than the old-fashioned method of manually clicking through filter options. You type in a description of who you're looking for, and Muraena translates that into the appropriate search filters. Fun fact that came up during research: "Muraena" is actually the name of an eel. But on AppSumo, it's all business.

As part of the That LTD Life series, this review puts Muraena through real-world searches to see whether those 140 million profiles actually deliver usable, high-quality leads — or if it's just another oversized database with questionable data.

Plans and Pricing

Muraena's entry point on AppSumo is $59 for a lifetime deal — a one-time payment that gets you ongoing access to the platform. Tier one includes up to 2,000 email credits per month, which is a reasonable starting point for freelancers or small teams running targeted outreach campaigns.

If you need more volume, tier two and tier three bump up your monthly email credits significantly. Tier three also unlocks API access, which is a big deal if you want to integrate Muraena directly with your CRM or cold emailing tool. There are even tier four and tier five upgrades available for power users.

For this review, the focus is on tier one at $59. The logic is simple: if you can close even a single client from Muraena's database, you've likely paid for the tool 30 to 40 times over. That's a low-risk entry point for any lead generation tool.

Getting Set Up

Setup is straightforward but comes with a notable friction point: Muraena requires Google sign-in. There's no option to create an account with just an email and password, which is a drawback if you prefer to minimize how much data flows through your Google account.

There's also a browser compatibility issue worth mentioning. On Safari, the "Continue with Google" button didn't work at all during testing. Switching over to Arc browser resolved the issue immediately. It's a minor hiccup, but if you run into trouble during activation, try a Chromium-based browser before assuming something is broken.

Once you're past the login, the interface is clean and ready to go. Muraena presents you with an AI search bar front and center, along with example queries to help you get started.

First Search: AI-Powered Lead Discovery

The first test search used a natural language prompt: "I design landing pages for online course creators. Find me some in the health and fitness niche." Muraena processed that and returned a traditional search results page — but with only seven results, several of which were duplicates from the same company (Barbary Inc., a legal education firm).

That's not exactly a bullseye for health and fitness course creators. Looking at what the AI actually did under the hood, it translated the query into job title filters like "Online Course Creator" and "Course Manager," and selected "E-Learning" as the industry. The filtering logic makes sense, but the results were too narrow and not particularly relevant.

This first test suggests the AI search works best as a shortcut for filling out filters rather than a genuinely intelligent lead discovery engine. It's convenient, but don't expect magic — you'll still want to refine results manually.

Search Filters and Targeting Options

Where Muraena gets more interesting is in its filtering sidebar. Beyond basic job title and industry filters, you get access to several advanced targeting options that can meaningfully narrow your search.

Technographics let you filter by the technologies a company uses — think WordPress, Google Apps for Business, or specific plugins. Buyer intent filters flag companies that Muraena believes are actively in the market for certain services, like email marketing or web development. You can also filter by country (it defaults to the United States), sub-regions, company headcount, and even whether a company has raised funding.

That funding filter is a smart inclusion. If you're targeting startups with marketing budgets, filtering for companies that have secured funding helps you avoid wasting outreach on bootstrapped operations that may not have the budget for your services. You can also search by personal LinkedIn URL or company name, which opens up some creative prospecting workflows.

Using Muraena with LinkedIn

One of the more practical use cases is combining Muraena with LinkedIn for contact enrichment. Here's the workflow: find someone interesting on LinkedIn using the free search, copy their profile URL, and paste it into Muraena's LinkedIn URL filter.

In testing, this worked impressively well. After finding an AI artist and course creator named Terza on LinkedIn, her profile URL was pasted into Muraena. The tool returned her profile immediately, and revealing her contact details produced two email addresses that appeared legitimate based on contextual clues in the addresses themselves.

This is a genuinely useful workaround for people who don't want to pay for LinkedIn Sales Navigator. Instead of trying to connect or message through LinkedIn's increasingly spammed inbox, you can grab the URL and use Muraena to find a direct email address. It essentially turns Muraena into a LinkedIn contact enrichment tool for a fraction of the cost.

Bulk Search and Export

A second test search asked for companies using WordPress and doing at least $1 million in revenue per year. Muraena returned over 300,000 leads — far too broad to be useful. But after narrowing down to the e-commerce industry and adding a buyer intent filter for email marketing, the list dropped to a much more manageable 512 leads.

Muraena supports both individual contact reveals (one credit each from your 2,000 monthly allowance) and bulk exports. For bulk exports, you can select all leads on a page or the entire result set, then export to CSV with all available fields included. Direct integrations with Pipedrive, HubSpot, and Lemlist are also available for streamlined workflows.

The bulk export is where Muraena's value proposition really comes through. Being able to pull 500+ targeted contacts into a CSV and feed them into your outreach stack is exactly what a tool like this needs to do well.

Advanced Search: Where AI Falls Short

A more advanced test pushed the AI search harder: "We manage LearnDash websites for content creators. Show us companies that use this software and are looking for web hosting and web development." The result? Zero leads.

This confirmed a suspicion from earlier testing — the AI search is essentially just auto-filling the traditional filter fields. It's a natural language interface layered on top of a standard database query, not a sophisticated AI that understands context or intent. When the query is too specific or combines multiple criteria in ways the filters can't handle, it simply returns nothing.

The better approach is to skip the AI search entirely for complex queries and go straight to the filters. Searching manually for companies using LearnDash returned 31,000 leads. That's a much more useful starting point that you can then refine with additional filters for headcount, region, or buyer intent.

Are the Leads Actually High Quality?

Lead quality is the make-or-break factor for any B2B database, and it's hard to fully evaluate in a single review. But some spot-checking provided encouraging results.

One lead from the LearnDash search was a founder of a company called Boosted (now Boostly). Cross-referencing on LinkedIn confirmed the company existed, and running their URL through WhatCMS.org verified they were indeed using WordPress. Digging deeper revealed they had LearnDash courses on their site. That's a legitimately well-matched lead.

Of course, one accurate result out of 32,000 isn't a comprehensive quality assessment. Some leads in the results were clearly irrelevant. The key takeaway is that the data isn't fabricated — it's pulling from real profiles and real technographic data. But you'll still need to do your own filtering and validation. Running exported emails through a verification tool like ClearOut or SMTP.com before any outreach is strongly recommended.

Final Verdict: Is Muraena Worth It?

Muraena earns a score of 7.1 out of 10. It's a solid B2B lead generation tool, especially at the $59 price point. The database is large, the filters are comprehensive, and the LinkedIn enrichment workflow alone could justify the cost for many users.

The AI search feature is more of a convenience than a game-changer — it fills out filters based on natural language, but it doesn't do anything you couldn't do manually. For best results, go straight to the filter sidebar and build your queries there. The real value is in the data itself and the ability to export it in bulk.

Keep in mind that Muraena is just one piece of a larger outreach puzzle. You'll want to pair it with an email verification tool to clean your lists, a warm-up tool like Inboxy to protect your sender reputation, and a cold outreach platform or CRM like HubSpot to manage your campaigns. Used as part of that stack, Muraena is a strong foundation — and at this price, closing even one deal from its database makes it a no-brainer investment.
