Gigasheet vs ReachStream: They're Not Actually Competitors
Comparing Gigasheet to ReachStream is like comparing Excel to Apollo - they sit at completely different stages of your data workflow. Gigasheet is a big-data spreadsheet that processes millions of rows you already have. ReachStream is a lead intelligence database that gives you new contacts to prospect. If you're evaluating these two side by side, you're probably solving the wrong problem.
Let's break this down so you don't waste a week trialing tools in the wrong category.
30-Second Verdict
ReachStream if you need a source of B2B contacts. Search by title, industry, and company size, then export lists for outbound. It's a lead database.
Gigasheet if you already have massive datasets and need to enrich, transform, and analyze them without code. It's a data-operations platform, not a prospecting tool.
What Each Tool Actually Does
ReachStream is a B2B contact database with 200M+ contacts, 95% claimed data accuracy, and 90% deliverability. You search by job title, industry, SIC code, technographics, company size, revenue, and geography down to zip code. It includes a Chrome extension, ESP-verified emails, and an ABM list builder.
Gigasheet handles up to 25 million rows per sheet and lets you enrich every row via no-code HTTP requests to any REST API - think Hunter, Apollo enrichment, Clearbit, or ChatGPT. Each enriched row consumes a credit. Gigasheet offers a free plan with paid tiers above it, but it's not a lead database. It's a workbench for teams that already have data and need to process it at scale.
Feature Comparison
| ReachStream | Gigasheet | |
|---|---|---|
| Category | Lead intelligence DB | Big-data spreadsheet |
| Database | 200M+ contacts | No native DB |
| Best for | Sourcing new leads | Processing existing data |
| Enrichment | Built-in | Via API credits |
| Chrome ext. | Yes | No |
| CRM integrations | Limited | N/A |
| G2 rating | 4.8/5 (52 reviews) | 4.9/5 (23 reviews) |
| Starting price | Free / $39/mo paid | ~$25/mo billed annually ($295/yr) |
In our testing, the category mismatch becomes obvious within minutes - one tool finds contacts, the other crunches spreadsheets. The CRM integration gap is ReachStream's biggest weakness right now. Five G2 reviewers specifically call out missing HubSpot and Salesforce connections. If that's a dealbreaker, the usual alternatives - ZoomInfo, Apollo, Lead411, Seamless.AI - all offer native integrations but at higher price points.
If you're weighing multiple sales prospecting databases, make sure you're comparing tools in the same category.
ReachStream lacks CRM integrations. Gigasheet doesn't source contacts. Prospeo does both - 300M+ profiles with native Salesforce, HubSpot, Smartlead, and Instantly connections. 98% email accuracy, 7-day data refresh, and $0.01 per email.

Pricing and Credits

|---|---|---|---|
| Icebreaker | Free | Free | 1,200 |

The free Icebreaker plan also includes 2,400 email views/year and unlimited contact/company views. Polar Peak advertises unlimited data downloads with the Chrome extension - a strong value prop if your workflow is extension-heavy.
If you're trying to keep spend down, compare this against other free lead generation tools before you commit.
Gigasheet Plans
Here's the thing: Gigasheet's pricing is a mess to navigate. Gigasheet Premium runs $95/mo monthly or $25/mo billed annually at $295/year, with 100 enrichment credits per month. Their official pricing page elsewhere lists "from $75/user/month billed annually" - which doesn't help clarify anything. MRF Explorer, their healthcare JSON product, starts at $295/user/month billed annually ($3,540/year) - a completely different product, and the naming doesn't make it obvious. Additional enrichment credits beyond the included 100 typically run $0.05-$0.15 each.
If you're doing a lot of list cleanup + append work, it can help to benchmark against dedicated data enrichment services.
What Real Users Say
We didn't find meaningful Reddit threads comparing these two head-to-head. Most user feedback lives on G2 and Capterra, which tracks with their niche positioning.
ReachStream (4.8/5, 52 reviews): Data accuracy is the top pro with 17 mentions. The Chrome extension gets consistent praise for quick, in-browser prospecting. CRM integration gaps remain the #1 complaint - frustrating for teams running HubSpot or Salesforce workflows.
Gigasheet (4.9/5, 23 reviews): Handling 2M+ row files in a familiar spreadsheet UI is the standout feature. The main gripe? Price once you move past the free tier.
If you're sanity-checking review sites, it helps to understand how a G2 rating is calculated.
Need Verified Contact Data Instead?
If your deal sizes sit below $25k, you probably don't need to wrestle with either tool's limitations. We've seen teams waste weeks evaluating tools in the wrong category when their real problem is getting verified emails and direct dials into a CRM fast.
Prospeo handles that directly - 300M+ professional profiles, 98% email accuracy, a 7-day data refresh cycle, and native integrations with Salesforce, HubSpot, Smartlead, Instantly, and more. The Chrome extension alone has 40,000+ users pulling verified contact info from any website in one click. At roughly $0.01 per email, it's a fraction of what ZoomInfo charges for comparable data quality.
If you're building a repeatable outbound motion, these sales prospecting techniques can help you turn data into meetings.
If your real problem is getting verified emails and direct dials fast, neither Gigasheet nor ReachStream solves it cleanly. Prospeo's 5-step verification, 125M+ mobile numbers, and 40,000+ user Chrome extension were built for exactly this.
75 free emails per month, no contract, no sales call required.
FAQ
Can Gigasheet replace ReachStream?
No. Gigasheet processes data you already have; ReachStream sources new B2B contacts. They serve different pipeline stages and aren't interchangeable. If you need both sourcing and processing, pair a contact database with Gigasheet's spreadsheet engine.
Is ReachStream good for healthcare prospecting?
Yes - ReachStream offers advanced healthcare filtering and has published case studies around healthcare-specific outreach. At $39-$99/mo, it's one of the more affordable options for medical and pharma lead lists.
What's a good free alternative for verified B2B emails?
Prospeo's free tier includes 75 verified emails and 100 Chrome extension credits per month - no sales call or contract required. That's more generous than ReachStream's Icebreaker plan for email verification specifically, and it includes 5-step verification with catch-all handling.
Who should actually compare Gigasheet vs ReachStream?
Almost nobody. The comparison only makes sense if you're evaluating your entire data stack at once - one tool for sourcing contacts, another for large-scale data processing. Most outbound teams just need a contact database with built-in verification, not a spreadsheet tool.
