ContactOut vs Gigasheet: How to Choose in 2026
These two tools barely compete. If you're comparing ContactOut vs Gigasheet, you're probably staring at a Chrome extension for pulling emails off professional profiles on one side, and a cloud-based big-data spreadsheet - think Excel on steroids - with a RevenueBase-powered contact database bolted on, on the other.
We dug into both platforms to map the actual overlap. Short version: it's thin.
30-Second Verdict
Pick ContactOut if you're a recruiter or SDR who needs quick, one-at-a-time email and phone lookups from professional profiles.
Pick Gigasheet if you're processing massive datasets - millions of rows - and need data enrichment at scale.
Skip both if your real need is verified emails without credit ceilings or a spreadsheet subscription. Prospeo covers 300M+ profiles at 98% email accuracy, starts free with 75 emails/month plus 100 Chrome extension credits, and doesn't force you into a platform you don't need.
Head-to-Head Comparison
| Feature | ContactOut | Gigasheet | Edge |
|---|---|---|---|
| Core purpose | Email/phone finder | Big-data spreadsheet | Depends on job |
| Database size | 350M professionals (40M companies) | 300M+ contacts (RevenueBase) | ContactOut (slightly) |
| Pricing | Starts at $29/mo; Sales tier $299/mo | $25/mo (annual) - $95/mo (monthly) | Gigasheet (entry price) |
| Credit model | Monthly credits by plan | 100 enrichment credits/mo (Premium) | Depends on use case |
| Enrichment | Built-in lookup | Multi-provider bulk enrichment | Gigasheet (flexibility) |
| Best for | Individual lookups | Bulk data processing | - |
| G2 rating | 4.4/5 (109 reviews) | 4.9/5 (23 reviews) | ContactOut (sample size) |
Gigasheet's G2 score looks impressive at 4.9, but 23 reviews versus 109 means ContactOut has roughly 5x the user feedback. We'd weight the larger sample more heavily.
Where ContactOut Wins
ContactOut's strength is speed-to-contact. You're on a professional profile, you click the extension, and you've got contact details in seconds. The platform claims access to 350M professionals from 40M companies, which puts it in the upper tier for database size.
The tradeoff? Credits. It's the number-one complaint on G2 reviews: users burn through their monthly allocation fast, especially high-volume sourcers. One common entry point is 300 email exports for $49/month, which disappears quickly if you're prospecting dozens of candidates a day. That credit anxiety is real, and it shapes how people use the tool - you start rationing lookups instead of prospecting freely.
If you're doing this kind of daily outreach, it helps to have a repeatable system for sales prospecting and follow-ups.
Credit anxiety kills prospecting momentum. Prospeo gives you 300M+ profiles at 98% email accuracy with no weekly credit ceilings - just $0.01/email on a 7-day refresh cycle that's 6x faster than industry average.
Stop rationing lookups. Start prospecting freely.
Where Gigasheet Wins
Gigasheet wins when the job is bulk data processing. We're talking up to 25 million rows per sheet on Premium, multi-provider enrichment through Apollo.io, Hunter Email Verifier, and People Data Labs, plus AI-powered column generation without code. The platform has processed over 13.75 trillion cells across 150,000+ users. It's built for scale, not individual lookups.
One nuance worth flagging: Gigasheet markets "no credit limits" around exports for its contact-database workflow, with unlimited exports up to 1M rows per export. But the Premium spreadsheet plan still caps you at 100 enrichment credits/month.
Pricing gets complex as you move upmarket. Premium runs $25/month billed yearly or $95/month billed monthly, while Business/enterprise packaging typically lands in the mid four-figures per year and up. On G2, reviewers call out that the subscription isn't cheap and that useful features keep migrating behind higher paywalls.
Here's the thing: if you're weighing ContactOut against Gigasheet, you probably need neither. It's like comparing a screwdriver to a table saw because both touch wood. Most people hitting this comparison actually need a dedicated email finder with solid accuracy - not a spreadsheet platform and not a credit-limited Chrome extension.
When Neither Tool Fits
Let's be honest about what most sales teams actually need. They don't need a spreadsheet that handles 25 million rows. They don't need a Chrome extension that runs dry mid-week. They need verified contact data that won't torch their sender reputation.
A lot of email-finding tools land in the mid-accuracy range - GetProspect, for instance, is often positioned around 85-90%. Prospeo delivers 98% accuracy across 300M+ profiles with a 7-day data refresh cycle, while most competitors refresh every six weeks. That gap matters when you're running outbound at volume and every bounce chips away at your domain health (see email bounce rate benchmarks).
The Chrome extension works across any website, and the mobile finder covers 125M+ verified numbers with a 30% pickup rate. Free tier gives you 75 emails/month plus 100 Chrome extension credits, paid plans run about $0.01/email, and it plugs directly into Salesforce, HubSpot, Lemlist, Instantly, and Clay.
You don't need a big-data spreadsheet or a credit-limited Chrome extension. Prospeo covers verified emails, 125M+ mobile numbers with 30% pickup rates, and plugs straight into HubSpot, Salesforce, and your outbound stack.
Purpose-built for contact data. Nothing you don't need.
Final Verdict
Choosing between ContactOut and Gigasheet comes down to your workflow:
ContactOut - recruiters and SDRs who live in Chrome and need instant individual lookups. Just budget for the credit limits.
Gigasheet - data analysts or RevOps teams processing massive files with multi-provider enrichment. Skip it if you don't need the spreadsheet.
Neither - sales reps, founders, or agencies who need verified emails and mobile numbers without credit restrictions. That's most people reading this, and it's the gap a purpose-built email finder closes best.
FAQ
Are ContactOut and Gigasheet the same type of tool?
No. ContactOut is a Chrome extension for finding emails on professional profiles. Gigasheet is a big-data spreadsheet with a RevenueBase-powered B2B contact database. They overlap on contact data but serve fundamentally different workflows - individual lookups vs. bulk data processing.
Does Gigasheet have credit limits?
Gigasheet offers unlimited exports up to 1M rows per export for its contact-database workflow, but Premium includes only 100 enrichment credits/month. ContactOut caps lookups and exports by plan tier, starting at 300 email exports for $49/month.
What's a good alternative if neither tool fits?
Prospeo hits 98% email accuracy with a 7-day refresh cycle across 300M+ profiles. The free tier includes 75 emails/month plus 100 Chrome extension credits, and paid plans cost roughly $0.01/email with no annual contract required.
Can I use Gigasheet just as an email finder?
Technically yes - Gigasheet's RevenueBase integration lets you search and export B2B contacts. But you're paying for a full spreadsheet platform at $25-$95/month to access a feature that dedicated email finders handle at lower cost with higher specialization.
