SignalHire vs Xverum: They Don't Actually Compete
Both names show up when you're researching B2B data tools, so the comparison seems natural. It isn't. SignalHire is a browser extension that reveals verified emails and direct dials one contact at a time. Xverum is a dataset vendor that sells bulk professional and company data via API. Comparing them is like comparing a fishing rod to a fish market - they solve fundamentally different problems for fundamentally different buyers.
Here's the thing: if you're an SDR or recruiter who just needs verified contact data fast, neither of these tools is necessarily the best fit. Let's break down what each actually does so you can decide for yourself.
30-Second Verdict
Pick SignalHire if you're an SDR or recruiter who needs to pull up a prospect's email and direct dial from a browser extension, one contact at a time, on a per-credit basis.
Pick Xverum if you're on a data engineering or RevOps team evaluating bulk dataset vendors to feed an enrichment pipeline - and you've got budget starting at $900/mo.
What Each Tool Actually Does
SignalHire: Contact Finder for Reps and Recruiters
SignalHire's pitch is simple: install the extension, land on a prospect's profile, and reveal their email and phone number. The database covers 850M+ profiles across 30M+ companies, and credits only get charged when a contact is successfully returned. That's a meaningful differentiator - most competitors charge credits whether the lookup succeeds or not. What works:
- Dead-simple UX - the extension works across multiple platforms and websites
- Unlimited users on every plan, no per-seat pricing
- Free plan gives you 5 credits/month (or 10/month with the extension) to test
What doesn't:
- Accuracy is the recurring complaint. G2 reviewers rate it 3.7/5 across 56 reviews, with outdated data and inconsistent results flagged repeatedly
- Capterra reviews (4.3/5, 34 reviews](https://www.capterra.com/p/150698/SignalHire/) include a notable billing incident where a user was charged a $497 annual renewal with no refund option
- Reddit recruiters echo similar frustrations - some find it useful for quick lookups, while others report returned phone numbers are often outdated or irrelevant
Pricing starts at $39/mo. SignalHire's own pricing page lists an Emails & Phones plan at $139/month billed monthly ($110/month billed annually). G2 also shows an "Emails and Phone numbers" option at $2,500/year. Compared to ZoomInfo's roughly $15,000-$18,000/year for a solo user, it's affordable. But you're getting a narrower tool with less reliable data.
Xverum: Bulk Data for Pipeline Builders
The number that matters most: Xverum's pricing begins at roughly $900/mo for firmographic datasets, with POI datasets at ~$1,800/mo and intent data APIs at ~$2.25 per 1,000 calls. Full access can scale to $100K/year. Free samples are available through Datarade, but this is enterprise procurement territory - not something you sign up for over lunch.
What you get for that spend is bulk data at scale: 750M+ professional profiles, 54M company profiles, 10M+ job postings, and 240M+ location records, all delivered via API in JSON and Parquet formats. Xverum's numbers aren't perfectly consistent across every page (one page references 46M companies and 250M+ POIs), but the overall scale is clear. Refresh rates can be as fast as 24 hours, with 300M+ records updated monthly.
Named #1 in Datarade's March 2026 firmographic data provider roundup, Xverum also offers a SERP Data API with a 100K-query trial, which signals real product breadth beyond B2B datasets. Coresignal's comparison page lists larger job posting coverage (425M+ vs Xverum's 10M+), while Xverum emphasizes fast refresh options and datasets spanning people, companies, jobs, and POIs.
The risks are real, though. Xverum has zero G2 reviews and just one Datarade review (5.0/5 - hardly a sample size). We've found that vendors with near-zero public reviews require extra due diligence before you sign annual contracts. Xverum doesn't collect data itself either - affiliated companies collect and organize it, and Xverum distributes. No Chrome extension, no per-contact lookup, no self-serve free tier for dataset products.
SignalHire charges credits for contacts that bounce. Xverum starts at $900/mo for bulk data you may not need. Prospeo delivers 98% verified email accuracy across 300M+ profiles, with data refreshed every 7 days - not 6 weeks. Start free with 75 emails and 100 extension credits.
Stop burning credits on outdated contacts. Get data that actually connects.

Which One Do You Need?
Most people evaluating SignalHire vs Xverum aren't data engineers shopping for bulk vendors. They're reps or recruiters who need verified contact data fast.
You're an SDR or recruiter who needs 50 verified emails by end of day. SignalHire is closer to what you need, but the accuracy complaints are real. We've seen teams burn through credits on outdated contacts, which defeats the purpose of a pay-per-success model if the "successes" bounce.
Your data team is evaluating bulk people-data vendors for an enrichment pipeline. Xverum is the right conversation. The refresh rates and dataset breadth are competitive, though the near-zero review footprint means you're betting on a vendor most of your peers haven't validated publicly.
For teams where the average deal size is under $25k, you almost certainly don't need Xverum's bulk data infrastructure. And if accuracy matters more than database size - which it should - SignalHire's 3.7-star G2 rating tells you everything you need to know about the tradeoff you're making.
The Self-Serve Alternative Worth Knowing
Prospeo sits in the sweet spot most people actually need: 300M+ professional profiles, 98% email accuracy, and 125M+ verified mobile numbers with a 30% pickup rate. Data refreshes every 7 days while the industry average sits at 6 weeks, and the Chrome extension has 40,000+ users pulling verified contacts from any website.
Where SignalHire charges credits for inconsistent data and Xverum requires enterprise procurement, Prospeo starts free - 75 emails and 100 Chrome extension credits per month, no credit card. Paid plans scale from ~$39/mo with no contracts. For individual reps, agencies, and SMB teams, it's the obvious pick.
If you need verified emails and direct dials without enterprise procurement or a 3.7-star accuracy gamble, Prospeo is the answer. 125M+ verified mobiles with a 30% pickup rate, 40,000+ Chrome extension users, and plans starting at ~$0.01 per email. No contracts, cancel anytime.
Enterprise-grade B2B data without the enterprise price tag or accuracy tradeoffs.
