LimeLeads vs Prospeo: Which B2B Data Tool Is Worth Your Budget?
These two tools sit in completely different weight classes. One's a US-only database with 20M contacts and CSV exports. The other covers 300M+ profiles globally with native integrations, intent data, and a 7-day refresh cycle.
The 30-second verdict: Prospeo wins for the vast majority of outbound teams. It's 4x cheaper at 5,000 credits, 15x larger in database coverage, and refreshes data 13x faster. The only reason to stick with LimeLeads is if you prospect exclusively US local businesses with unpredictable volume and don't need integrations.

Pricing Breakdown
Pricing is where LimeLeads falls apart for most teams.
| Plan | LimeLeads | Prospeo |
|---|---|---|
| Entry | $99/mo (500 credits) | Free (75 emails/mo) |
| Mid | $150/mo (1,500 credits) | $39/mo (1,000 credits) |
| High volume | $400/mo (5,000 credits) | $99/mo (5,000 credits) |
| Scale | N/A | $199/mo (20,000 credits) |
| Business | N/A | $369/mo (50,000 credits) |
At 5,000 credits, you're paying $0.08/credit with LimeLeads or roughly $0.02/credit with Prospeo - a $3,600/year difference for the same volume, except Prospeo's credits come with global coverage, verified mobiles, intent data, and API access.
LimeLeads offers 35% annual discounts, bringing the Enterprise plan to ~$260/mo. Still about 2.6x Prospeo's price for equivalent volume. LimeLeads does include multiple user seats on higher tiers (up to 5 seats on Enterprise), which matters for larger teams. They also refund credits for bounced contacts - a fair policy, though with a 90-day refresh cycle, you'll use that refund more often than you'd like.
LimeLeads charges $400/mo for 5,000 credits covering 20M US contacts with a 90-day refresh. Prospeo gives you 5,000 credits for $99/mo across 300M+ global profiles refreshed every 7 days - with 98% email accuracy, 125M+ verified mobiles, intent data, and native CRM integrations included.
Save $3,600/year and get 15x more coverage. No credit card required.
Data Quality and Freshness
Here's the thing about LimeLeads' accuracy claims: they're all over the map. Their pricing page says 98%+. TrustRadius lists 95%+. A Woodpecker blog review cites 99%. That's not a rounding difference - that's a credibility gap. Their sole G2 reviewer specifically flagged email accuracy as a weakness, and the G2 profile itself is marked "Inactive," unmanaged for over a year.
To be fair, LimeLeads' sole Capterra reviewer (5/5) praised lead quality as comparable to tools costing 4-5x more. But that review is from 2020, and the tool hasn't evolved much since.
The refresh cycle is the bigger issue. LimeLeads updates its database every 90 days. B2B contact data decays roughly 30% annually, so stale records pile up fast between refreshes. Prospeo refreshes every 7 days, running every record through a 5-step verification process that includes catch-all handling, spam-trap removal, and honeypot filtering. If you're tightening your process, follow an email verification list SOP alongside your data provider.
We've seen the difference firsthand: teams like Meritt cut bounce rates from 35% to under 4% after switching to weekly-refresh data, and their pipeline tripled from $100K to $300K/week.
Features and Integrations
Use LimeLeads if you only need a basic search-and-download workflow for US contacts and you're fine managing CSV files manually. (If you're evaluating other options in this category, start with our roundup of B2B data providers USA.)
Skip LimeLeads if you run any kind of automated outbound workflow, need CRM sync, want an API, or prospect outside the US.
It's 2026 and LimeLeads still requires CSV exports and manual CRM imports. No API. No Chrome extension. No confirmed native integrations - despite some directories mentioning HubSpot and Salesforce, the vendor hasn't specified any on their own site.
Prospeo connects natively to Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Clay, Zapier, and Make - your data flows into your outbound stack without CSV gymnastics. The Chrome extension, used by 40,000+ people, pulls verified emails and phones from any website in one click (see our picks for email finder extensions). Layer on 30+ search filters, intent data tracking 15,000 topics via Bombora, and a full B2B lead enrichment API with a 92% match rate, and you're looking at a modern data platform versus a basic list-builder.
Let's be honest: LimeLeads isn't bad for what it is. But what it is belongs in 2018. If your outbound stack has more than one tool in it, you need a data provider that actually connects to the rest of your workflow.
One security note worth flagging: in 2020, LimeLeads suffered a data breach that exposed 49 million records through an unsecured Elasticsearch server. They fixed it within a day, but it's worth considering if you're in a regulated industry.
Who Should Use Which
Stick with LimeLeads if you prospect exclusively US local businesses, don't need an API or CRM integrations, have wildly unpredictable volume (those non-expiring credits help), and genuinely don't mind CSV exports. In a Reddit roundup of list-building tools, one user ranked LimeLeads last out of seven, calling it best for "unlimited downloads (US-only)" - a fair summary.
Choose Prospeo if you need global coverage, verified accuracy, API access, integrations, intent data, or you're running any automated outbound workflow. In our experience, the weekly refresh cycle alone justifies the switch for most teams - stale data doesn't just hurt reply rates, it burns your sending domain (use a warmup email process if you're recovering deliverability).
Unless you have a very specific US-only, low-volume, no-integration use case, Prospeo outperforms LimeLeads on every metric that matters: database size, accuracy, freshness, pricing, integrations, and security track record.
CSV exports and manual imports aren't a workflow - they're a bottleneck. Prospeo connects natively to Salesforce, HubSpot, Smartlead, Instantly, Lemlist, and Clay, with a full API at 92% match rate. Teams like Meritt cut bounce rates from 35% to under 4% and tripled pipeline after switching.
Stop managing spreadsheets. Start closing deals with data that actually connects.
FAQ
Is LimeLeads' data accurate?
LimeLeads claims 95-99% email accuracy depending on which page you read, and their only G2 reviewer flagged accuracy as a weakness. The 90-day refresh cycle means records decay significantly between updates. Prospeo delivers 98% accuracy through a 5-step verification process refreshed every 7 days.
Does LimeLeads have an API?
No. LimeLeads offers CSV and Excel exports only - no API, no Chrome extension, and no confirmed native CRM integrations. Prospeo provides a full API with a 92% match rate plus native integrations with Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Clay, Zapier, and Make.
Can I use LimeLeads for international prospecting?
