ContactOut vs LFBBD: SaaS Tool or Data Broker?
ContactOut and LFBBD aren't competing products - they're different product categories entirely. Comparing them is like comparing a vending machine to a wholesale distributor. ContactOut is a self-serve SaaS platform with a Chrome extension for one-at-a-time prospecting. LFBBD is a data broker that delivers bulk CSV/XLS files within 24-48 hours. Same goal, completely different workflows.
We've tested both, and the choice really comes down to how your team prospects - not which database is "better." If you’re pressure-testing your process, start with a few sales prospecting techniques that match your volume and channels.
30-Second Verdict
- Pick ContactOut if you need a Chrome extension for instant, one-at-a-time lookups and can live with credit caps.
- Pick LFBBD if you need bulk data delivered in spreadsheets for large campaigns and don't mind waiting a day or two.
How Each Tool Works
ContactOut
ContactOut covers 300M professionals across 30M companies, and over 76% of Fortune 500 companies reportedly use it. The core experience lives inside a Chrome extension: browse professional profiles, click, and pull emails and phone numbers instantly. On G2, 75% of reviewers gave it five stars (4.4/5 from 109 reviews), and the extension genuinely earns that rating for individual prospecting.
The Sales plan runs $79/user/month, with a free tier for light usage. Third-party pricing breakdowns commonly list an Email plan around $99/month and an Email+Phone tier around $199/month.
Here's the thing: even "unlimited" marketing is still limited in practice. Fair-use caps on those plans land at roughly 2,000 emails and 1,000 phone numbers per month - about 91 daily lookups. That's not unlimited by any reasonable definition. G2 reviewers also flag outdated contacts and slow extension loading as recurring pain points.
Recruiters and solo SDRs who prospect from professional profiles will love the workflow. Teams running outbound at scale will hit the credit wall fast - especially if you’re tracking lead generation metrics and need consistent throughput.
LFBBD (Lead for Business)
LFBBD's accuracy claims don't add up, and that tells you a lot. The FAQ says 95%. The features page says 97-99%. A separate section claims 98% for one dataset. Datarade reviewers land closer to ~95% validity in practice, which is the number we'd trust. Some Trustpilot reviewers also mention irrelevant leads mixed into otherwise accurate lists.
The database is large: 500M+ professionals, 30M+ companies, 130M+ work emails, and 50M+ mobile numbers across 200+ countries. You place an order, specify targeting criteria, and receive a CSV or XLS file within 24-48 hours. Pricing starts at $100 on Datarade, with rates around $45 per 1,000 records or $1,000 per million contacts. Annual plans go up to ~$14,999/year.
Reviews are positive but thin - 4.3/5 on Trustpilot from just 15 reviews. Teams needing large, one-time data pulls for campaign launches will find the per-record pricing competitive. But a 15-30 day refresh cycle and a 24-48 hour delivery window won't work for daily prospecting. LFBBD also has virtually no Reddit footprint, which makes independent vetting harder. And because delivery is spreadsheet-based, teams typically end up doing manual CSV imports into whatever CRM or sequencer they use.
ContactOut caps you at ~91 lookups per day. LFBBD makes you wait 24-48 hours for a spreadsheet. Prospeo gives you real-time access to 300M+ profiles with 98% email accuracy, 125M+ verified mobiles, and a 7-day data refresh - not 15-30 days. Native integrations with HubSpot, Salesforce, Instantly, and Lemlist mean no more manual CSV imports.
Skip the credit walls and stale spreadsheets. Start prospecting in real time.

The real gap isn't in the numbers - it's in the workflow. ContactOut is built for reps who prospect one contact at a time from a browser. LFBBD is built for ops teams who need bulk data delivered as a file. Neither gives you real-time access to a large, continuously verified database with native integrations to your outbound stack. If you’re evaluating options broadly, compare against other sales prospecting databases before committing.
Let's be honest: if your outbound volume is under 500 contacts per month, ContactOut's credit caps won't bother you and LFBBD is overkill. If it's over 500, both tools start breaking down - ContactOut runs out of credits, and LFBBD's batch files go stale fast. That middle-to-high volume range is exactly where a third option makes more sense. (If you’re sending at scale, it’s also worth understanding email velocity so you don’t burn domains.)
What If Neither Fits?
One of our customers, Snyk, cut their bounce rate from 35-40% down to under 5% after switching, with 50 AEs now sourcing 200+ new opportunities per month. The free tier gives you 75 emails and 100 extension credits monthly, no credit card required. If bounce is a recurring issue, start with the fundamentals in our email bounce rate guide.
Snyk's 50 AEs dropped their bounce rate from 35-40% to under 5% and now source 200+ new opportunities per month. That's what happens when your data refreshes every 7 days instead of every 15-30. At $0.01 per email, Prospeo costs a fraction of ContactOut's $79/user/month - with no fair-use caps hiding behind "unlimited" marketing.

FAQ
Is LFBBD's data really 95% accurate?
Their own site quotes 95%, 97-99%, and 98% in different places. Datarade reviewers land around ~95% validity in practice. Always run bulk lists through a verification tool before launching sequences - bouncing 5% of a 100K list will torch your sender reputation.
Does ContactOut offer unlimited lookups?
No. Fair-use caps on "unlimited" plans sit at roughly 2,000 emails and 1,000 phone numbers per month - about 91 daily lookups. That's fine for a solo recruiter, but it won't support a five-person SDR team.
Is there a free way to test all three tools?
Yes. ContactOut has a free plan with limited credits. LFBBD offers free samples through Datarade. Prospeo gives 75 free emails plus 100 Chrome extension credits monthly - no credit card required. Test all three on your actual target accounts before committing budget.
