Adapt.io vs NinjaPear: Which B2B Data Tool Fits Your Team?
The Adapt.io vs NinjaPear decision comes down to workflow ownership, not feature checklists. Adapt.io is a sales prospecting database you hand to reps today. NinjaPear is an API-first company intelligence layer you build into pipelines. Pick the wrong one and you'll waste weeks forcing a tool into a workflow it wasn't designed for.
30-Second Verdict
- Adapt.io wins if your sales team needs a contact database and Chrome extension right now.
- NinjaPear wins if engineering owns enrichment and you're building company intelligence via API.
What Is Adapt.io?
Adapt.io is a classic sales prospecting and enrichment platform built for the "find a person, get an email, push to sequence" workflow. It offers 250M+ contacts, a Chrome extension for quick lookups, and CRM integrations for enrichment.
Pricing is credit-based, not seat-based. The free plan gives you 25 email credits and 25 enrichment credits per month. Starter runs $49/month for 500 of each. Basic bumps to $99/month with 1,000 email credits and 100 phone credits. There's also a Custom tier for higher volumes and API access.
With 2,789 G2 reviews averaging 4.6/5, it's a proven tool - though we've seen it work best when RevOps keeps the credit model tight and reps aren't spraying unchecked exports into Salesforce.
What Is NinjaPear?
NinjaPear is a "B2B Company Intelligence Platform" from the Nubela team behind Proxycurl, which shut down in 2025 after a LinkedIn lawsuit at roughly $10M in self-reported revenue. NinjaPear launched in 2026 as the reboot, with a focus on data ownership and ethical sourcing boundaries - no scraping professional social media platforms, no scraping behind login walls - and a heavier emphasis on company-level intelligence.
Here's the part most comparisons skip: before pivoting to data, NinjaPear v1 was an AI live chat tool that attracted 163 registered users and zero integrations. The current product is a fundamentally different bet.
It's API-first with Python and Node.js SDKs, built around turning a website URL into customers, competitors, and employee intelligence. The docs spell out rate limiting up to 300 requests/minute using a 5-minute window, with burst capacity up to 1,500 requests per 5 minutes. If you're an engineering team that thinks in endpoints rather than Chrome extensions, this is the product's sweet spot.
NinjaPear doesn't have an established G2 or Capterra review footprint yet. That makes the contract terms a bigger gamble if you're buying without a deep technical pilot. On Reddit, the Proxycurl shutdown thread is mostly about the lawsuit timeline, and NinjaPear is still too new to have a meaningful public track record.
Head-to-Head Comparison
This isn't "which is better." It's which matches your operating model.
| Category | Adapt.io | NinjaPear |
|---|---|---|
| Primary use case | Sales prospecting | Company intel API |
| Data coverage | 250M+ contacts | Company intelligence (customers/competitors/employees) |
| Pricing entry | $0 (Free plan) | $49/mo |
| Full pricing range | $0-$99/mo + Custom | $49-$1,899/mo |
| Contract terms | Monthly available | 12-month minimum |
| API access | Custom tier | Core product |
| Rate limits | Plan-based | Up to 300 req/min (burst to 1,500/5 min) |
| Chrome extension | Yes | No |
| CRM integrations | Native | Via API |
| G2 reviews | 2,789 (4.6/5) | None yet |
| Email verification | Verified contact emails (credit-based) | Disposable email checker |
Our take: NinjaPear is asking for 12-month commitments on a product without a mature third-party review footprint and with a predecessor that got sued into shutdown. If your average deal size sits below $25k, that risk-reward math doesn't work. Adapt.io is the safer bet for most sales teams. NinjaPear only makes sense if engineering owns the data stack and you've validated the API in a real pilot.
Pricing and features verified as of March 2026.
Neither Adapt.io's Custom-tier API gate nor NinjaPear's 12-month lock-in should be the cost of accurate B2B data. Prospeo gives you 300M+ profiles, 98% verified emails, and a 7-day data refresh - all self-serve at ~$0.01/email with no contracts.
Get enterprise-grade data without the enterprise commitment.
Pricing Gotchas
Use this section like a pre-mortem. These are the terms that bite teams later.
NinjaPear's commitment trap. All monthly and annual plans come with a 12-month commitment, even on "monthly" billing. Cancellation fees equal the remaining months left unpaid. Subscription credits expire at the end of each billing cycle, so you can't bank them. PAYG credits last 18 months - a critical distinction if you're evaluating commitment levels.
Customer Listing costs multiply fast. It's 1 credit per request plus 2 credits per customer returned. A domain that surfaces 50 customers burns 101 credits in a single call. Run that across a few hundred target accounts and you'll blow through a mid-tier plan in days.
The trial is almost useless. Three days and 10 credits isn't enough to validate real workloads against a product with no reviews to reference. We've run pilots on tools with similarly tight trials, and the result is always the same: you end up committing before you've actually tested anything meaningful.
Adapt.io's Custom tier is where API access and higher-volume phone credits usually land - and it's "Contact Us" pricing, so budget accordingly.
Strict commitments paired with expiring credits is a red flag for any team running a pilot.
Which One Should You Pick?
Choose Adapt.io if you're enabling reps with a contact database, Chrome extension, and quick list exports on self-serve tiers before talking to sales. Your workflow is prospect, enrich, sequence.
Choose NinjaPear if engineering owns enrichment and you're building customer/competitor mapping or company intelligence pipelines via SDK. But negotiate the commitment terms hard - or start with PAYG credits to limit exposure.

The No-Contract Alternative
Teams using Prospeo book 26% more meetings than ZoomInfo users and 35% more than Apollo users. That tracks with what we see when bounce rates stop wrecking deliverability - one of our customers, Snyk, dropped their bounce rate from 35-40% to under 5% and saw AE-sourced pipeline jump 180%. And unlike NinjaPear, there's no 12-month lock-in. Cancel anytime.
If you're pressure-testing deliverability impact, start with bounce rates and work backward into your email deliverability stack.
NinjaPear's 3-day trial with 10 credits won't validate anything. Adapt.io's free tier caps you at 25. Prospeo gives you 75 free emails and 100 Chrome extension credits every month - enough to run a real bake-off before you spend a dollar.
Run your pilot on a platform that actually lets you pilot.
FAQ
Is NinjaPear the same as Proxycurl?
Same Nubela team, different product. Proxycurl shut down in 2025 after a LinkedIn lawsuit, and NinjaPear launched in 2026 with explicit sourcing boundaries - no scraping professional social media platforms or behind login walls - and a focus on company-level intelligence rather than individual profile scraping.
Can I cancel NinjaPear monthly?
No. All plans require a 12-month commitment even when billed monthly. Cancellation fees equal the remaining months left unpaid, and unused subscription credits expire each billing cycle.
Is there a free alternative to both Adapt.io and NinjaPear?
Prospeo's free plan gives you 75 emails and 100 Chrome extension credits per month with no credit card required. Adapt.io also offers a limited free tier at 25 credits. NinjaPear has no free plan - only a 3-day, 10-credit trial that's too short for meaningful evaluation.
