Here's the 30-second verdict, then the details to back it up.
Pick SignalHire if you're rolling out a tool to a team. Unlimited users, shared credits, 850M+ profiles, and a recruiting-friendly data model.

Pricing and Credit Economics
LeadLeaper's pricing is genuinely confusing. Different pages and reviews reflect different plan generations, and we've spent more time than we'd like trying to reconcile them.
The current product shows a free tier with 100 email credits/month, paid plans starting at $49/month (Basic) and $69/month (Professional). But Woodpecker's LeadLeaper review lists an older structure: free with 200 credits, Basic at $39/mo for 3,000 credits, Professional at $59/mo for 10,000 credits. G2 shows yet another layer - ProspectorPlus at $110/user/month and ProspectorPro at $125/user/month.
For most solo users, budget $49-$69/month on current standard tiers. If you're looking at higher-tier per-user plans, expect $110-$125/user/month based on what G2 reflects.
SignalHire is more straightforward. The free plan gives you 5 credits/month (or 10 if you install the extension). Paid plans start at $39/month and they're built around a shared credit pool - every paid plan includes unlimited users, so your whole team works from the same account. Third-party pricing breakdowns commonly show SignalHire around $57/month for Emails, $39/month for Phones, and $167/month for Emails & Phones on annual billing.
Let's be honest though: stop comparing plan prices in isolation. Calculate cost per usable contact. Lead finders often look cheap until you factor in missing data, undeliverable emails, and time spent re-checking contacts. Test a small batch against your real ICP before committing annual.
Data Coverage and Verification
SignalHire's 850M+ profile database spans multiple platforms and emphasizes real-time verification with 95%+ accuracy (they reference a 96% hit rate in some materials). For recruiting teams that need personal phone numbers alongside work emails, this is the stronger data model. The extension covers professional profiles, GitHub, Facebook, and company websites - useful when sourcing people who don't maintain traditional profiles.
SignalHire's credit rule is also team-friendly: 1 credit is deducted only if at least 1 email or phone is returned.
LeadLeaper takes a different approach entirely. It's an extension-led workflow where you capture contacts while browsing professional profiles, then move them into engagement flows. That's genuinely valuable for solo operators who want prospecting and follow-up in one place. But LeadLeaper doesn't publish a public accuracy figure, which matters - finding a contact, verifying it exists, and confirming it's deliverable are three different things.
Neither LeadLeaper nor SignalHire publishes a data refresh cycle - meaning the contacts you pull today could be stale tomorrow. Prospeo refreshes all 300M+ profiles every 7 days and verifies emails through a proprietary 5-step process that delivers 98% accuracy. At $0.01 per email, you spend less and bounce less.
Stop comparing finders. Start comparing deliverability.
Workflow Fit: Recruiting vs Sales
Six recruiters, one budget. Your finance team won't love per-seat pricing for a sourcing tool. SignalHire is the obvious play here: unlimited users means all six recruiters share one credit pool under a single plan. The extension also works across professional profiles, GitHub, Facebook, and company websites, which matters when you're sourcing candidates who don't keep profiles current everywhere.
Solo SDR, inconsistent follow-up. You're a founder or solo rep, and the problem isn't just finding contacts - it's the gap between finding them and actually reaching out. LeadLeaper's sequences, tracking, and contact management help close that gap without adding a separate outreach platform. On the Professional tier, you get event-triggered engagement, behavioral lead scoring, open/link/reply tracking, and a lightweight CRM layer with activity records, notes, and reminders. You can export or sync contacts into your main CRM when you need more advanced pipeline reporting.
Reliability and Risks
LeadLeaper holds a 4.5/5 on G2 from 45 reviews (77% five-star). Users consistently praise ease of use and fast email capture. Recurring complaints include: sometimes it doesn't generate data, weak customer support, and loading/performance issues including glitches and freezing. Heavy usage can also create platform risk - one user described aggressive usage leading to a one-day suspension.
There's also a visibility issue worth knowing about. A Reddit thread about Chrome Web Store "shadow banning" specifically cites LeadLeaper as an extension with 100,000+ users that can be visited via direct link but doesn't appear in Chrome Web Store search results.
SignalHire positions itself with 850M profiles and over 3 million users, plus real-time verification and team-wide credit sharing. On the downside, third-party writeups frequently mention accuracy complaints, confusing pricing and UX, technical issues, and customer service concerns. Some users also dislike losing credits when results are incomplete.
When Neither Tool Is Enough
Both tools help solve the "find" problem. Neither fully solves the "verify and keep fresh" problem - and that's where teams lose money fast. Poor data quality costs organizations $12.9M per year on average.
If your bounce rates are above 5%, the issue isn't which finder you're using. It's what happens after the lookup.
We've tested this gap extensively. Prospeo covers it with 300M+ profiles, 98% email accuracy, and a 7-day data refresh cycle versus the 6-week industry average. It also includes 125M+ verified mobile numbers with a 30% pickup rate - roughly 2.5x the industry average for direct dials - which makes it particularly strong for outbound teams. Credit-based pricing starts around $0.01 per email, with a free tier of 75 emails/month plus 100 Chrome extension credits/month. Self-serve, no contracts.
Shared credits and built-in sequences are nice, but they don't fix a 5%+ bounce rate. Prospeo combines 98% email accuracy, 125M+ verified mobiles with a 30% pickup rate, and 30+ search filters including buyer intent - all on a 7-day refresh cycle. Teams using Prospeo book 26% more meetings than ZoomInfo users and 35% more than Apollo.
Find contacts, verify them, and actually connect - all in one platform.
Final Recommendation
Pick SignalHire if you're a team of 3+, need unlimited users under one plan, and your use case leans recruiting-heavy with personal phone numbers.
Pick LeadLeaper if you're a solo operator who wants built-in sequences, lead scoring, and engagement tracking without paying for a separate outreach platform.
Pick Prospeo if accuracy and freshness are the bottleneck - 98% verified emails, 125M+ mobiles, 7-day refresh, and no per-seat gating.
FAQ
Does SignalHire charge per seat?
No. All paid SignalHire plans include unlimited users. Pricing is based on credits and data type (emails, phones, or both), not headcount - making it significantly cheaper than per-seat tools for teams of 3+.
Is LeadLeaper free?
Yes. The free plan includes 100 email credits per month. Paid plans start at $49/month for more credits and engagement features like sequences, lead scoring, and open tracking.
Can I use SignalHire for bulk enrichment?
Yes. Bulk upload supports lists of up to 1,000 names, and SignalHire's fair usage policy limits spending to 2K credits/month. For larger enrichment jobs, tools with API access and higher throughput scale better - Prospeo's enrichment API handles this at a 92% match rate.
