MuraenaA low-cost contact database with AI search, technographics and funding data. A fit for small teams and founders.
Muraena is a small B2B prospecting tool. Its homepage says it covers 180M+ professionals and 30M companies, with 280M emails and 25M phone numbers.
Starting from your own won, lost and open deals, not from a typed description or your website, and showing the reason on each account.
Ocean is contextual intelligence for go-to-market. It reads what every company actually does from its own website, learns what good looks like from your closed-won and closed-lost deals, and ranks your whole market against it, with the reason behind each score. The ranked accounts arrive in your CRM, your rep queue or your AI agents.
What buyers weigh, grouped by the job each part does. A light blue background marks the stronger side.
| Topic | Ocean | Muraena |
|---|---|---|
| Finding the right accounts | ||
| Lookalikes | Ocean is stronger here. Core of the product. Segments and models learned from your won and lost CRM deals. | You describe your ideal customer or enter your company domain, and its AI suggests companies. The input is a description or your own website, not your customer results. |
| Learns your ICP from won and lost deals | Ocean is stronger here. Learned automatically from your won and lost deals. | It doesn’t describe reading your CRM’s won and lost deals. Your ICP comes from what you type or your domain. |
| The reason behind each account | Ocean is stronger here. Segment, score, tier and matched signals on every account and every export. | Shows funding, technographics and intent topics on each company. We found no explanation of why a company matched your ICP. |
| Coverage | Ocean is stronger here. Segments your whole market and shows win rate, deal size and cycle time for each segment. | Says it indexes every global business website and covers 30M companies. Other listings quote different database sizes. |
| Contacts and data | ||
| Contacts | Verified emails and direct phones from a waterfall across 16+ data sources. Charged only when a contact is found, and exports are free. | A verified email database of 280M emails and 25M phone numbers by its own count, with credits for emails starting at 50 a month free. |
| Technographics and funding data | Answers custom questions from each company’s own website. It doesn’t resell funding rounds or a technology catalog. | Technographic profiles, funding stages and amounts, and buyer-intent insights across 7,500 topics and 250 categories on every plan. |
| Buying signals | Up-to-date signals built in-house from each company’s own teams, leaders, hiring and website. | Third-party intent topics and funding rounds. We found no documentation of where the intent data comes from. |
| Workflow and pricing | ||
| CRM sync | Two-way with HubSpot, Salesforce, Pipedrive and Attio. Reads your deals to learn, then writes scores, segments and signals back. | Exports to CSV, Pipedrive, lemlist and HubSpot, and has a Pipedrive Marketplace app. It describes an export, not a two-way sync. |
| AI agents and MCP | MCP server, public API and a chat agent on the same data and lookalike engine. | API access on the Business plan, plus AI search in the app. We found no MCP server documented. |
| Security and privacy | SOC 2 Type II and GDPR, per Ocean’s own site. | We couldn’t open a security or compliance page for it. Ask for its reports and how it sources contact data. |
| Pricing | Two ways to buy: a flat-rate plan with credits included, or a custom plan built around your deals and credit volume. | Free, then $19 and $89 a user a month, priced by email credits. |
Muraena publishes three plans, priced per user a month on email credits. All include technographics, buyer-intent insights, unlimited AI search and exports.
G2 and Capterra still show older prices of $39 and $149, so use Muraena’s own pricing page. Credits are for emails, and its FAQ lists a custom plan above Business. Some third-party listings describe a lifetime deal on AppSumo, which isn’t a current plan.
A flat-rate plan with credits included, or a custom plan built around your deals.
Contacts are charged only when one is found. Exports are free.

Choose Muraena if Already on Muraena?Five steps, working back from your renewal date.
Export the companies and contacts from your Muraena searches, then run them through Ocean to see how many fit your closed-won pattern.
Find your plan, your remaining email credits and your renewal date.
Connect HubSpot, Salesforce, Pipedrive or Attio. Ocean reads your closed-won and closed-lost deals to learn what a good account looks like.
Ocean proposes segments and scores, with the reason on each. Correct anything that doesn’t match how you sell.
Scores, segments and matched signals go back to your CRM, or into Apollo, Instantly or Lemlist sequences.
Expect a polished demo on sample data, because that is where it looks best; ask for a test on your own accounts.
Expect an accuracy claim, because vendors measure it on their own samples; test find and bounce rates on your own list.
Expect export and no-code connectors first, with two-way sync tied to the plan; confirm what is live on yours.
Expect a trust-center link or a request form, because reports sit behind a sales step; ask for the date and scope.
Ocean is better because it tells it like it is: contextual intelligence to find your next deal, with the reason on every account.
