Adapt.io vs LimeLeads: Which B2B Database Is Actually Worth It?
Adapt.io has 2,789 G2 reviews. LimeLeads has one. That gap alone tells you something, but database size, pricing, and email accuracy matter more than review counts - so let's break it down properly.
30-Second Verdict
Adapt.io wins this head-to-head for the vast majority of teams. It has global coverage, a well-reviewed Chrome extension, API access, and a 250M+ contact database sitting behind nearly 2,800 G2 reviews at 4.6/5. LimeLeads is a US-only database with a single G2 review, an inactive profile, and a 2020 data breach on its record.
Here's the thing: if your outbound volume is high enough to compare these two tools, you probably need better email accuracy than either one delivers. More on that below.

Adapt.io - What You Get
Use this if you need a global B2B database with a solid Chrome extension and API access. The extension alone gets 71 positive mentions on G2, and the platform scores 9.1/10 for ease of use. It feels fast in day-to-day prospecting - the credit limits are the real bottleneck.
Pricing runs Free (25 email credits/day), Starter at $49/mo for 500 credits, Basic at $99/mo for 1,000 email plus 100 phone credits, and Custom for API access and team features.
Skip this if you burn through credits fast. The top complaint across G2 (34 mentions) is credit limitations - users hit walls mid-campaign. Another 14 reviewers flagged incorrect email addresses, which is a real problem when you're running high-volume outbound and your domain reputation is on the line.
Adapt.io users flag credit limits and incorrect emails. LimeLeads is US-only with a single G2 review. Prospeo gives you 300M+ global profiles, 98% email accuracy, and 125M+ verified mobiles - with 30+ filters including buyer intent and technographics. No credit walls, no coverage gaps.
Stop choosing between coverage and accuracy. Get both at $0.01/email.
LimeLeads - What You Get
Use this if you exclusively prospect US-based contacts and want simple CSV exports without needing API access or a browser extension. Pricing starts at $99/mo for 500 credits on the Pro tier, $150/mo for 1,500 credits on Business, and $400/mo for 5,000 credits on Enterprise, with 35% off annual billing. Credits never expire, and LimeLeads offers refunds for invalid or hard-bounced emails - a fair policy.
Skip this if you need international coverage or API workflows. LimeLeads' G2 profile hasn't been active for over a year, and its single reviewer said the platform needs to improve email accuracy - despite the vendor claiming "99% email data accuracy" on its homepage. That disconnect between marketing copy and user experience is a red flag. There's also a 2020 data breach that exposed 49 million records. Not a great look for a data vendor.
Key Differences That Matter
Global vs. US-only. Adapt.io covers contacts worldwide. LimeLeads only provides US-based lead data. If you sell into EMEA, APAC, or LATAM, LimeLeads simply isn't an option.
API access. Adapt.io offers Prospect, Enrich, and Refresh APIs on its Custom plan. LimeLeads has no API - third-party directories note it's in development, but there's no timeline. For any team running enrichment workflows or connecting to tools like Clay or Make, this is a dealbreaker.
Social proof gap. We've seen teams pick tools based on feature lists alone, only to regret it when support disappears or the product stagnates. Adapt.io's 2,789 reviews signal an active product with a real user base. LimeLeads' single review and inactive profile suggest the opposite. B2B data decays at roughly 3% per month, so you need a vendor actively investing in data freshness - and review activity is a reasonable proxy for that investment.
When Email Accuracy Is the Real Problem
The difference isn't just the numbers. Prospeo runs a proprietary 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering - it doesn't rely on third-party email providers the way many competitors do. We've watched teams cut bounce rates from 35%+ down to under 4% after switching, which has a direct impact on email deliverability and reply rates.
Beyond email, Prospeo covers 125M+ verified mobile numbers with a 30% pickup rate - something neither Adapt.io nor LimeLeads can match. Add 30+ search filters including buyer intent data via Bombora, technographics, and job change signals, and it's a different tier of platform entirely. Native integrations with Salesforce, HubSpot, Smartlead, Instantly, and Clay mean it slots into existing workflows without duct tape.
Both Adapt.io and LimeLeads leave you guessing on data freshness. Prospeo refreshes every 7 days - not 6 weeks - and runs a proprietary 5-step verification that cuts bounce rates from 35%+ to under 4%. Teams using Prospeo book 26% more meetings than ZoomInfo users and 35% more than Apollo.

FAQ
Is LimeLeads really $29/month?
No. Older blog posts list $29/mo, but current pricing starts at $99/mo for 500 credits. Always check the official pricing page - vendor blog content often lags behind actual pricing by years.
Does Adapt.io have a free plan?
Yes. The free tier includes 25 email credits per day - enough to evaluate data quality and the Chrome extension, but not enough for real outbound campaigns. Paid plans start at $49/mo.
Is there a better alternative to both?
For most outbound teams, yes. Look at the numbers: 300M+ profiles, 98% email accuracy, 125M+ verified mobiles, and intent data covering 15,000 topics - all self-serve at roughly $0.01 per email. That covers the global reach of Adapt.io and the simplicity of LimeLeads without the accuracy tradeoffs of either.
