Leadsrush vs Ninjapear: Email Finder vs B2B Data API (2026)

TL;DR

• Leadsrush is a self-serve lead generation app. It finds and verifies emails, searches domains, finds local businesses and looks up tech stacks. It's built for SDRs, agencies and small sales teams who work in a UI.
• Ninjapear is Nubela's API platform, built after Proxycurl shut down. It returns company intelligence (customers, investors, partners and competitors) along with company and person data. It's built for developers and AI-agent builders.
• If your problem is "I need a verified email for this person," choose Leadsrush. If your problem is "I need to know who this company sells to and who it competes with," choose Ninjapear.
• Neither tool does everything. Many teams pair a company-intelligence API with a dedicated email finder and verifier.
• Our pick: Leadsrush for hands-on outbound on a small budget, Ninjapear for data-hungry product and RevOps teams building their own pipelines.

What is Leadsrush vs Ninjapear, and why are people comparing them?#

The "leadsrush vs ninjapear" search mostly comes from buyers who are reshuffling their data stack. Many of them relied on Proxycurl, which shut down in July 2025 after LinkedIn sued it. Now they're checking which replacements cover the same jobs.

The two products look alike on a feature checklist, since both "enrich B2B data." They solve different problems, though.

Leadsrush (leadsrush.io) comes from Reganam Ltd, a team that has done lead generation for more than eight years. It's a web app. You type a company, a name or a location, and you get contacts back. The main modules are:

• Email Finder (name + company → email)
• Email Verifier
• Domain Search (list the known employees and emails at a domain)
• Local business finder (location + keyword → B2B businesses)
• Technology lookup (which companies run a given tool on their site)
• 18 native CRM and email-marketing integrations, with one-click export

Ninjapear (nubela.co) is the API platform the Proxycurl team built next. It doesn't scrape LinkedIn. It's built around public sources and centres on company relationships:

• Customer Listing endpoint: customers, investors and partners of any company, queried by website URL
• Competitor Listing endpoint: a company's competitors, with a stated reason for each
• Company data and person/employee profiles
• Monitoring, pay-as-you-go credits and client libraries for Python and JavaScript

So it isn't really one email finder against another. It's a prospecting UI against a data API.

How do Leadsrush and Ninjapear compare feature by feature?#

The table below lists what each product does out of the box as of 2026. Vendors ship updates often, so check the current product pages before you commit budget.

Here's the short version. Leadsrush gives you contacts you can email today. Ninjapear gives you context you can reason over: who buys from whom, who competes with whom, and which companies deserve a closer look.

What does Leadsrush do best?#

Leadsrush is strongest when a rep needs a list by Friday and has neither an engineer nor a large budget.

1. Speed from search to send. Enter a company or a location and keyword, pick the decision-makers, verify, and push them to your CRM in one click. You don't write any code.
2. Local and SMB prospecting. The location + keyword search suits agencies selling to plumbers, dental clinics or regional logistics firms. Most enterprise data vendors cover these segments poorly.
3. Verification in the same app. Verification has its own credit pool, so finding emails doesn't eat into your checking budget.
4. Team-friendly billing. Every plan includes unlimited users, and the stored-prospect limit rises from 250 on Free to 50,000 on the top tier.

Where it's weaker: the credits are simple, but they reset each month. One search credit returns up to ten results, which is generous for broad domain searches and wasteful for single lookups. You also won't get relationship data. Leadsrush can tell you who works at a company. It can't tell you who that company's customers are.

What does Ninjapear do best?#

Ninjapear is the tool you use when the account list matters more than the contact list.

1. Customer graph data. Point the Customer Listing endpoint at a website and get back that company's customers, investors and partners. This is the fastest way to build lookalike lists ("sell to everyone who buys from our competitor") or to find warm-intro paths through shared investors.
2. Competitor intelligence with reasons. The Competitor Listing endpoint names each competitor and explains why they compete. That's useful for battlecards, positioning and account scoring.
3. Built for agents and pipelines. Clean REST docs (nubela.co/docs), official SDKs and per-endpoint credit costs make it easy to wire into an AI agent, a Clay-style workflow or an internal enrichment job.
4. Fair billing for bursty usage. Pay-as-you-go credits last 18 months, and failed requests are never charged. That matters when you enrich messy input lists where many domains won't resolve.

Where it's weaker: Ninjapear isn't a point-and-click prospecting tool, and emailable contacts aren't its core output. If you're a lone SDR with no developer, you'll hit a wall fast. Buyers moving over from Proxycurl should also note that it deliberately doesn't scrape LinkedIn, so don't expect Proxycurl's old LinkedIn profile endpoints to map one-to-one.

Is Leadsrush better than Ninjapear for cold outbound?#

Yes, if "cold outbound" means sending emails this week. Outbound needs three things in this order:

1. A target account list, meaning who to go after
2. The right people at those accounts, with roles and seniority
3. A deliverable email address for each person

Leadsrush covers steps 2 and 3 well and step 1 reasonably well, through tech lookup and local search. Ninjapear covers step 1 very well and part of step 2, but it doesn't finish the job at step 3.

That's why many RevOps teams run a split stack. A company-intelligence API builds and scores the account list. A dedicated email finder plus email verification turns those accounts into contacts you can actually send to. If you send to unverified addresses from a relationship dataset, your bounce rate climbs and you damage your sender reputation.

Which one is cheaper in practice?#

Sticker prices mislead here because the two products bill for different units.

Leadsrush uses monthly plans. At the time of writing, the free plan gives you 50 searches and 100 verifications a month, Starter costs about $29/mo and Growth about $59/mo, and higher tiers exist for bigger teams. Credits reset every billing cycle, so you pay for capacity whether or not you use it. That works well for steady weekly prospecting and is wasteful if your outbound comes in bursts.

Ninjapear charges per endpoint call in credits, with two options:

• Subscription credits: a lower per-credit rate, but they expire at the end of each cycle
• Pay-as-you-go credits: a higher rate, but they stay valid for 18 months

Check Ninjapear's pricing page for current per-endpoint credit costs. Relationship endpoints usually cost more per call than a simple lookup, because each response carries far more information.

A rule of thumb:

• If you enrich more than a few hundred contacts every month through a UI, a flat monthly plan like Leadsrush's is usually cheaper.
• If you run large, irregular batch jobs (for example, re-scoring your whole TAM each quarter), long-lived pay-as-you-go API credits like Ninjapear's usually waste less money.

Who should choose Leadsrush, and who should choose Ninjapear?#

Match the tool to the job in front of you, not to the longest feature list.

• Solo founder or SDR, no engineer: Leadsrush. You'll be sending emails within an hour of signing up.
• Agency prospecting local or SMB businesses: Leadsrush. Location + keyword search and unlimited seats suit agency workflows.
• RevOps team building an ICP/TAM model: Ninjapear. Customer and competitor graphs are hard to get anywhere else at this price.
• Product team building an AI sales agent: Ninjapear. It's API-first, has SDKs, and failed calls aren't charged.
• Former Proxycurl customer: Ninjapear for company and relationship data. Plan a separate tool for emails and LinkedIn-derived fields.
• Team that needs both account intelligence and emailable contacts: use Ninjapear (or a similar API) for accounts, then run a dedicated email finder and verifier on the people.

What do reviewers say about each tool?#

Independent review coverage is still thin for both. Leadsrush is a smaller product that launched through Product Hunt and a RocketHub lifetime deal. Ninjapear is a 2025–2026 rebrand, so most of its history sits under the Proxycurl name. If you read reviews on G2, keep a few things in mind:

• Proxycurl reviews describe the old LinkedIn-scraping product, not Ninjapear's current public-source data.
• Lifetime-deal reviews of small tools tend to skew positive in the first year. Check how recently the reviewers used the product.
• Accuracy for a data tool depends on the market you're checking. Run your own test on 50 to 100 contacts from your real ICP before you trust any vendor's accuracy claim.

A simple test works for both. Take 50 companies you already know well, with known customers, known competitors and known email formats. Run them through each tool and score what comes back. This takes an afternoon and will tell you more than any comparison page, including this one.

Where does Tomba fit next to Leadsrush and Ninjapear?#

Tomba sits on the contact side of this comparison, which is the job Ninjapear doesn't try to do. Its core product is an email finder that works by name + domain, company or LinkedIn profile. A verifier, a catch-all verifier, domain search, a phone finder and enrichment sit alongside it.

In practice it plays two roles:

• As a Leadsrush alternative for teams that want a larger database, API access and integrations with HubSpot, Salesforce, Google Sheets and similar tools. Plans start with a free tier of 25 searches a month, then $49/mo Starter, $99/mo Growth and $249/mo Pro. See the full Tomba pricing.
• As the email layer behind Ninjapear. Pull a customer list from Ninjapear, pass the domains to a domain search or finder, and verify the results before they reach your sequencer.

Neither role requires you to drop the tool you already use. The best B2B data stacks in 2026 are usually built from a few tools, each good at one job. They aren't one platform that claims to do everything.

Frequently asked questions#

Is Ninjapear the same as Proxycurl? It's built by the same team (Nubela) at the same domain, but it's a different product. Proxycurl shut down in July 2025 after LinkedIn's lawsuit. Ninjapear uses public sources, doesn't scrape LinkedIn, and focuses on customers, competitors and company data.

Does Leadsrush have an API? Leadsrush is built mainly as a web app with native integrations. If API-first access is a hard requirement, confirm the current API scope with their team before you buy.

Can Ninjapear find email addresses? Emailable contacts aren't its core output. Use it to decide which companies to target, then use a dedicated finder and verifier to reach the people there.

Which is better for agencies? Leadsrush, in most cases. Unlimited seats, local business search and one-click CRM export fit how agencies work. Ninjapear suits agencies that sell data or competitive analysis as a service.

The verdict: Leadsrush or Ninjapear?#

Choose Leadsrush if your bottleneck is contacts: you know who you want to reach and you need verified emails in your CRM today, on a small budget, without writing code.

Choose Ninjapear if your bottleneck is targeting: you want to know who your prospects' customers and competitors are, and you have someone who can call an API.

If you need both, which covers most growing outbound teams, don't force one tool to do the other's job. Build accounts with a relationship-data API and fill in contacts with a dedicated finder.

When you reach that second step, try Tomba Email Finder. Start with the free plan (25 searches a month), run it on a sample of the accounts you pulled from Ninjapear or Leadsrush, and compare how many deliverable emails you get back before you spend anything.
