LeadIQ vs SourceScrub: They're Not Competitors - Here's What You Actually Need
You're comparing a contact capture tool to a PE deal sourcing platform. That's the core confusion behind every LeadIQ vs SourceScrub search - it's like comparing a telescope to a telephone. One finds targets, the other reaches them.
LeadIQ grabs emails and phone numbers for SDR outreach. SourceScrub identifies private companies for deal pipeline. The real question isn't which one to pick. It's which contact data layer to pair with whichever workflow you're running.
30-Second Verdict
- Choose SourceScrub if you're a PE or corp dev team sourcing private companies for deal pipeline across 16M+ profiles.
- Choose LeadIQ if you're an SDR team running high-volume outbound and need quick contact capture integrated with your sequencer.
- Skip both if your real problem is bounced emails and bad phone numbers - Prospeo delivers 98% email accuracy and 125M+ verified mobile numbers with no annual contract, starting free.

What SourceScrub Does
SourceScrub is a private-market intelligence platform built for PE firms, M&A teams, and corporate development. It profiles roughly 16M companies across 220,000+ sources - including 190,000+ scrubbed conference and trade show lists - to surface hard-to-find private businesses. Used by 700+ firms including KKR, TA, and Hg, it also offers an AI copilot called SourcingGPT that helps analysts get smart on a sector fast.
Here's what matters if you're evaluating today: Datasite acquired SourceScrub in August 2025 and is integrating its data into Grata, which covers 19M+ private companies. Your buying decision is increasingly about the combined Grata + SourceScrub roadmap, not the standalone product.
Three tiers exist - Discovery Essentials, Sourcing Plus, and Winning Professional - all demo-led with firm-wide packaging and optional web-extension-only seats. Expect $20K-$80K/year for smaller teams and $100K+/year for larger deployments. The company data is excellent. Contact accuracy? That's a known weak spot.
Use this if you're sourcing private companies for deal pipeline. Skip this if you need accurate contact details for outreach.
SourceScrub's company data is excellent - but its contact accuracy isn't. Prospeo gives deal teams 300M+ profiles with 98% email accuracy and 125M+ verified mobiles on a 7-day refresh cycle, so your outreach actually lands after sourcing.
Don't plug a $50K sourcing tool into a broken contact layer.
What LeadIQ Does
Here's the thing about LeadIQ: across 1,160 G2 reviews, "inaccurate data" appears 72 times and "incorrect numbers" 40 times. That tells you everything. It's a B2B contact capture tool SDR teams love for its workflow and often criticize for phone accuracy. Pull a batch of contacts, load them into Outreach, watch too many bounce, and you can damage your domain reputation fast.
The tool runs on a universal credit model: 1 credit per email, 10 per phone number. Free gives you 50 credits. Essential runs $36/user/month with 1,000 emails and 50 phone numbers. Pro is $79/user/month with 2,000 verified emails and 100 phone numbers. Enterprise is custom and annual-only. Native integrations with Salesforce, HubSpot, Outreach, and Salesloft make it a natural fit for reps already living in those tools.
Our hot take: LeadIQ is a great workflow tool wrapped around mediocre data. If your average deal size sits below $10K, the bounced emails will cost you more in domain reputation than the tool saves in prospecting time.
Why This Comparison Doesn't Make Sense
Look - we've seen this confusion repeatedly. Teams evaluate these side by side when they actually need both layers. Altvia's PE tech stack breakdown illustrates the real workflow: SourceScrub identifies target companies, then a separate contact data tool finds the emails and phone numbers for outreach. With 59% of VC firms increasing tech spend to improve deal execution, the question isn't which tool - it's which stack.
SourceScrub isn't a contact-capture tool. LeadIQ isn't a deal sourcing platform. The real decision is which contact data tool gives you accurate enough data that your outreach actually lands.
The Accuracy Layer Both Workflows Need
Both SourceScrub and LeadIQ users hit the same wall: bounced emails and bad phone numbers. We've tested this extensively, and the gap between "good enough" contact data and verified contact data is the difference between 35% bounce rates and under 4%.
Prospeo fills that gap with 300M+ professional profiles, a 7-day data refresh cycle versus the six-week industry average, and pricing around $0.01 per email. For deal teams pulling hundreds of contacts from a sourcing platform, that means pennies for data that connects instead of thousands for data that bounces. With 98% email accuracy and a 30% mobile pickup rate, it's the verification layer that makes either workflow actually produce meetings.
Let's be honest - if you're spending $50K+ on SourceScrub to find the right companies, then losing half your outreach to bad emails, you've got an expensive funnel with a hole in the bottom.
LeadIQ users report inaccurate data 72 times across G2 reviews. Prospeo's 5-step verification delivers 98% email accuracy at ~$0.01/email - no annual contract, no domain damage, no wasted credits on bad numbers.

FAQ
Is SourceScrub being discontinued?
Not exactly. Datasite acquired SourceScrub in August 2025 and is merging it into Grata, which covers 19M+ private companies. The standalone product is transitioning - if you're evaluating today, you're effectively evaluating the combined Grata + SourceScrub roadmap.
Can I use LeadIQ for PE deal sourcing?
No. LeadIQ captures contact details from professional profiles. It doesn't source private companies, track M&A signals, or build deal pipeline. For that, you need SourceScrub or Grata. LeadIQ sits downstream in the outreach step.
What's the most accurate contact data tool for deal teams?
Prospeo delivers 98% email accuracy and 125M+ verified mobile numbers on a 7-day refresh cycle. It's self-serve, starts free with 75 emails per month, and requires no annual contract - a strong fit for PE teams that need reliable outreach data without enterprise sales overhead.
Do I need both LeadIQ and SourceScrub?
Only if you're a PE team running outbound to deal targets. SourceScrub finds companies; a contact tool finds people at those companies. But LeadIQ isn't the only option downstream - and given the data accuracy complaints across 1,160+ reviews, it's worth testing alternatives before committing.
