ContactOut vs Crustdata: Which One Do You Actually Need?
ContactOut and Crustdata both sell B2B data. That's where the similarity ends.
Comparing these two is really comparing two different product categories - one's a Chrome extension built for recruiters pulling personal emails, the other's an API-first data infrastructure layer built for engineers piping signals into AI platforms. With roughly 2.5% of any contact database going stale every month, picking the wrong tool means you're working with decaying data. On r/SaaS, users regularly complain about enrichment tools returning job titles from two years ago, and we've seen the same frustration firsthand when auditing prospect lists for clients.
The 30-Second Verdict
Recruiter or individual SDR? Pick ContactOut. Chrome extension, personal emails, no engineering required.

Data engineer or platform builder? Pick Crustdata. API infrastructure, real-time signals, 340+ datapoints per record.
What Each Tool Actually Does
ContactOut
ContactOut is a contact finder, plain and simple. It covers 250M+ professional profiles, delivers emails and phone numbers via a Chrome extension, and scores a 4.4/5 on G2 across 109 reviews. The sweet spot is recruiters and sourcers who need personal emails - not just work addresses.
One recruiter on r/Recruitment tested multiple providers and landed on ContactOut specifically for "much stronger personal email coverage" and "lower bounce rates compared to Apollo or Lusha." They'd set up quarterly data imports through Gem and Greenhouse because they didn't have engineering resources for API integration. That's the profile: non-technical users who need reliable contact data without a build project.

Crustdata
Crustdata doesn't compete with ContactOut - it competes with building your own data pipeline. Backed by Y Combinator with a $6M seed round closed in late 2025, it's an API-first data broker targeting builders: teams constructing AI SDRs, AI recruiting platforms, and internal sales automation.
The numbers tell the story. 60M+ companies, 1B+ people profiles, and 340+ datapoints per record pulled from 16+ verified sources. The Watcher API is the standout feature - real-time webhooks for job changes, promotions, and funding rounds that fire the moment something changes. If you don't have a developer on your team, this product isn't for you.

ContactOut is built for recruiters. Crustdata is built for engineers. If you're a sales team that just needs verified emails and direct dials, Prospeo covers 300M+ profiles at 98% accuracy with a 7-day refresh cycle - no Chrome-only limitations, no API build project required.

Features and Pricing Compared
| Feature | ContactOut | Crustdata | Prospeo |
|---|---|---|---|
| Primary use | Contact finder | Data infrastructure | Self-serve B2B data |
| Data delivery | Extension + UI + API | API + flat file + webhooks | Extension + UI + API |
| Database size | 250M+ profiles | 60M+ cos, 1B+ people | 300M+ profiles |
| Datapoints/record | Email + phone + basic | 340+ | 50+ |
| Data freshness | Hourly updates | Real-time updates + webhooks | 7-day refresh |
| Email accuracy | Not published | Not published | 98% verified |
| Verified mobiles | Included (Phone plan) | People fields incl. phone | 125M+, 30% pickup |
| Pricing model | Per-seat subscription | Credit-based API + custom | Credit-based, ~$0.01/email |
| Starting price | $99/mo (Email plan) | Free tier; paid = custom | Free (75 emails/mo) |
| G2 rating | 4.4/5 (109 reviews) | Limited review presence | - |
| Engineering needed | No | Yes | No |
ContactOut's Email plan runs $99/mo for 300 exports, and the Email+Phone plan hits $199/mo for 600 exports - though "unlimited" emails and phones come with fair-use caps around ~2,000 emails/month. Crustdata doesn't publish pricing because production workloads are custom-quoted, but expect mid-to-high four figures monthly once you outgrow the free tier. For context, independent analyses of Apollo-sourced lists have found bounce rates of 25-35%, so sales data quality has a real cost regardless of which tool you choose.
Who Should Use Which
Pick ContactOut If...
- You're a recruiter or sourcer who lives in a Chrome extension
- Personal emails matter more than company emails
- You use Gem, Greenhouse, or similar ATS tools and want direct enrichment
- You don't have engineering resources and quarterly bulk imports work fine
- Your budget is $99-199/mo per seat

Pick Crustdata If...
- You're building an AI sales or recruiting platform and need raw data infrastructure
- You have developers who can integrate API endpoints and handle webhooks
- You need 340+ datapoints per record for ML pipelines or scoring models
- Real-time job change and funding signals via the Watcher API are core to your product
- Flat-file data delivery for analytics pipelines is a requirement
Here's the thing: most B2B teams shopping this comparison don't actually need either tool. ContactOut is built for recruiters. Crustdata is built for engineers. If your average deal size is under $50k and you just need accurate emails and direct dials to fill a pipeline, you're overcomplicating it.
If Neither Fits
Most sales teams don't need a recruiter-focused Chrome extension or an API data broker. They need verified emails and direct dials they can trust, delivered through a platform they can use without writing code or negotiating a contract.
We've seen teams switch from ContactOut when they outgrow the recruiter-focused workflow and need intent data, technographics, and funding signals layered into their prospecting. Prospeo covers 300M+ professional profiles with 98% email accuracy and 125M+ verified mobile numbers hitting a 30% pickup rate. Data refreshes every 7 days - the industry average is 6 weeks. The Chrome extension has 40,000+ users and works on any website or CRM, with native integrations into Salesforce, HubSpot, Smartlead, Instantly, Lemlist, and Clay.

Let's be honest - one of our clients at Stack Optimize built from $0 to $1M ARR using Prospeo data, maintaining 94%+ deliverability and under 3% bounce rates across all their client campaigns with zero domain flags. That's the kind of reliability that matters when your reputation is on the line. If you're tightening up sending and inbox placement, follow email deliverability best practices before scaling volume.
The free tier gives you 75 verified emails and 100 Chrome extension credits per month. Enough to test before committing a dollar.


Bounce rates from stale data don't just waste credits - they burn your domain. Prospeo refreshes every 7 days, verifies emails through a 5-step process, and delivers 125M+ mobile numbers with a 30% pickup rate. Stack Optimize built to $1M ARR on it with under 3% bounce rates.
Test 75 verified emails free. No credit card, no sales call.
