Gigasheet vs WarpLeads: Data Analysis Tool or Lead Database?
The Gigasheet vs WarpLeads comparison keeps surfacing because both tools handle large datasets. That's where the similarity ends. Gigasheet is a big-data spreadsheet for analyzing millions of rows without code. WarpLeads is a B2B lead database for exporting contacts in bulk. Comparing them is like comparing Excel to Apollo - they solve fundamentally different problems, and you probably landed here because you're evaluating both for some stage of your outbound pipeline. Here's the breakdown.
30-Second Verdict
Pick Gigasheet to analyze, filter, or visualize massive CSV/JSON files without SQL or coding skills. On Gigasheet Premium, you can work with up to 25M rows per sheet.
Pick WarpLeads for a cheap, high-volume B2B lead database with unlimited exports at $99/mo.
Skip both if you need verified contact data for outreach. Prospeo delivers 98% email accuracy across 300M+ professional profiles on a 7-day refresh cycle - the data quality that actually converts.
What Each Tool Does
Gigasheet
Use this if you're drowning in massive files - multi-million-row CSVs, JSON dumps, healthcare MRF data - and need a spreadsheet interface to explore them without writing a single line of code.
Gigasheet handles up to 1 billion rows on its MRF Explorer tier, connects to tools like Snowflake and BigQuery, and is SOC 2 Type II certified. The Premium plan also includes enrichment credits and Gigasheet AI for insight generation, which can help you pull useful signals from your own datasets. G2 rates it 4.9/5 under Big Data Analytics - one of the highest scores in that category.
WarpLeads
Use this if you want raw volume. That's it.
WarpLeads positions itself as a B2B database with access to 100M+ contacts and 20M+ companies. You get filters including a Technology filter, exclude lists, de-duplication, bulk lookup, and bulk export where you can select up to 10,000 records at once. There's also a Chrome extension that finds publicly available email addresses and phone numbers on websites. The "unlimited exports" pitch at $99/mo is what draws buyers in.
Here's the thing: if your outbound strategy depends on volume over accuracy, WarpLeads will fill your CRM fast. But filled CRMs don't close deals - verified contacts do. We've watched teams celebrate hitting 50,000 exports only to torch their sending domain within two weeks because half the addresses were dead.
WarpLeads gives you volume. Prospeo gives you accuracy. Upload your bulk exports and verify every address against 300M+ profiles refreshed every 7 days - not every 6 weeks. At ~$0.01 per email, cleaning a 10,000-row export costs less than one burned domain.
Stop celebrating export counts. Start celebrating reply rates.
Pricing Breakdown
| Feature | Gigasheet | WarpLeads |
|---|---|---|
| Starting price | $25/mo (annual) or $95/mo (monthly) | $99/mo |
| Annual option | $295/year (Premium); higher tiers available | No annual plan for Unlimited |
| Row/contact limits | Up to 25M rows/sheet (Premium) | Unlimited exports |
| Data exports | Unrestricted | Up to 10K records/batch |
| API access | Add-on available | $299/mo billed quarterly ($897/quarter) |
| Compliance | SOC 2 Type II | Not stated |
| Best for | Analyzing large files | Bulk lead export |
Gigasheet's Premium tier runs $95/mo monthly or $295/year billed annually, with higher price points for larger packages. For healthcare machine-readable file workflows, MRF Explorer starts at $295 per user/month billed annually.
WarpLeads keeps it simpler: free at 30 contacts/month, unlimited at $99/month. API access starts at $299/month billed quarterly and requires an active Unlimited subscription, with rate limits of 300 requests/min, 800 requests/hour, and 4,000 requests/day.
Now here's the interesting part. WarpLeads also sells add-on export bundles ranging from $40/mo for 5,000 exports up to $2,800/mo for 1M exports - alongside the "unlimited" plan. That suggests the unlimited tier has practical throughput constraints nobody advertises upfront. Also worth knowing: WarpLeads has a strict no-refunds policy.
How Data Quality Compares
"$99 for unlimited exports" sounds incredible until you actually send those emails.
The #1 concern on Reddit about WarpLeads is data quality - one B2B marketing company reported "quality is terrible (high bounce rate, old emails etc)" even after running a separate verification pass. When someone on r/coldemail posted "$99 for unlimited exports? lol really?" - that captures what experienced outbound operators feel. We've seen this pattern dozens of times: a team gets excited about cheap volume, blasts 20,000 unverified contacts, and spends the next month rebuilding domain reputation from scratch.
The common workaround is pairing WarpLeads with Apollo for targeted leads and a cleaning tool to scrub bounces. One user reported closing 38 deals that way - but it means WarpLeads is just the first step in a multi-tool pipeline.
For that verification step, Prospeo handles it with 98% email accuracy, 125M+ verified mobiles with a 30% pickup rate, and a 7-day data refresh cycle versus the 6-week industry average. Upload a CSV of bulk exports, verify in bulk, and only send to addresses that are actually live. Free tier starts at 75 emails/mo, paid plans from ~$39/mo, no contracts.
Skip the three-tool stack. Prospeo combines 30+ search filters, 98% verified emails, and 125M+ direct dials in one platform. Build targeted lists, verify in real time, and push straight to HubSpot, Salesforce, or your sequencer - no WarpLeads cleanup required.
One platform. Verified data. Zero domain risk.
Who Should Pick What
Analyzing 5GB CSVs or healthcare MRF data? Gigasheet. Purpose-built for this, nothing else comes close at that row scale.
Building outbound lists at scale on a tight budget? WarpLeads. Just don't send without verifying first - seriously.
Need volume, analysis, and accuracy together? Let's be real, that's a three-tool stack: export from WarpLeads, analyze segments in Gigasheet, verify contacts through Prospeo before outreach. That's the full workflow when you're weighing Gigasheet vs WarpLeads for a complete pipeline.
Skip WarpLeads entirely if your team doesn't have a verification step baked into the process. The money you save on lead sourcing, you'll spend ten times over recovering burned domains.
FAQ
What's the difference between Gigasheet and WarpLeads?
Gigasheet is a big-data spreadsheet for analyzing massive files - up to 1B rows - without coding. WarpLeads is a B2B lead database for exporting contacts at $99/mo. They serve entirely different workflows: one analyzes data, the other generates lead lists.
Is WarpLeads' $99 unlimited plan really unlimited?
WarpLeads advertises no export limits at $99/mo, but they also sell export bundles from $40 to $2,800/mo alongside it, and users consistently report high bounce rates. Budget for a verification tool before any outreach to avoid burning your sending domain.
How do I reduce bounce rates on exported lead lists?
Run every export through a verification tool before sending. A 7-day data refresh cycle catches stale addresses that volume databases miss - bulk CSV verification flags invalid contacts so you only sequence confirmed-valid emails. In our experience, teams that verify see bounce rates under 4% versus 20%+ without it.
